Fasting Can Prevent Cardiovascular Diseases

Dr. Joel Kahn gave a lecture in Las Vegas in which he explained that fasting can prevent cardiovascular diseases. Dr. Kahn is a Clinical Professor of Medicine at Wayne State University School of Medicine. He spoke at the 27th Annual World Congress on Anti-Aging Medicine in Las Vegas. The conference took place from Dec. 13 to 15th, 2019.

According to the CDC cardiovascular diseases like heart attacks and strokes are hitting the middle age adults in large numbers. Part of the problem is obesity and diabetes, both of which cause an increase of cardiovascular diseases. Heart attacks, strokes, heart failure and other related cardiovascular conditions caused 2.2 million hospitalizations in the US in 2016. This resulted in 415,000 deaths and a health care cost of $32.7 billion.

Fasting can improve the risk for cardiovascular disease

Dr. Kahn asked whether fasting can reduce the aging pathways, build up resilience and protect the heart from aging and heart disease. In a few words: eat less, live more! He showed with slides that fasting can indeed do that. One heart catheterization study showed that a fasting group had only 64% coronary artery disease compared to a non-fasting control group with 76%.

Another study showed that fasting patients had only 10.3% diabetes compared to controls with 22.0%. With heart catheterization 63.2% of fasting patients had cardiovascular disease while 75.0% of non-fasting control patients did have lesions in their coronary arteries.

Animal experiments confirmed that fasting had beneficial effects on heart health as well. In rats, researchers showed that fasting reduced infarct size and inflammation. It also preserved left ventricular function. With mice fasting produced less inflammatory response and less tissue damage.

Alternate day fasting shows benefit in clinical human trial

A 2019 publication reported about a 4-week randomized clinical trial on 60 healthy non-obese human subjects. The effect of alternate day fasting was compared to controls. On average there was a 37% calorie reduction in the alternate fasting group. The fasting group had improved fat mass, improved fat-to-lean ratio and cardiovascular markers. There was a reduction of age-associated inflammatory markers and low-density lipoprotein.

Fasting mimicking diet

A newer form of fasting is the fasting mimicking diet (FMD), which was invented and researched in depth by Dr. Valter Longo. Both animal experiments as well as human trials have shown that the FMD is safe and effective. It can be followed 5 days out of every month and will lead to some weight loss, an increase of telomeres, stem cells and lowered inflammatory markers.

My own experience with the fasting mimicking diet

My wife and I heard about the FMD from Dr. Longo when he spoke about it at the 2017 Anti-Aging Conference in Las Vegas. We immediately started the FMD in December of 2017 and have done it every month for 5 days since. But we never ordered the expensive meal kit. Instead, we calculated calories and use regular food to do the calorie-restricted diet. We eat 600 to 700 calories every day during the FMD days. In between we have unrestricted calories, but we noticed that we are more careful about our meal choices. I find that the result of the FMD is more energy, an improved sleep pattern and an easier way to keep my body-mass index in the 21.0 to 22.0 range. Here is a description of the effects of the FMD.

Use of FMD in high-risk patients

Dr. Khan said that the FMD is an ideal diet that the high-risk population of the US should use. 34% of the US population has a compromised metabolic condition. They are obese and at a high risk to develop diabetes. But on the FMD they gradually lose abdominal obesity, lower their cholesterol and triglycerides levels, which otherwise causes a high risk for heart attacks and strokes. The fasting blood sugar is lowering reducing the risk to get diabetes. The systolic and diastolic blood pressure comes down. And the C-reactive protein, which is a general inflammatory marker, becomes lower.

In non-obese patients the main effect of the FMD is a stimulation of stem cell release and telomere elongation. This postpones the aging process and with it delays the onset of cardiovascular diseases.

Fasting Can Prevent Cardiovascular Diseases

Conclusion

Dr. Joel Kahn gave a lecture at a Las Vegas conference that fasting can prevent cardiovascular diseases. He compared alternate day fasting with the fasting mimicking diet (FMD). The FMD was more effective in reducing danger markers, abdominal girth measurements and blood markers of cardiovascular diseases. Ultimately, he said, it was easier to follow an FMD where you only reduce your calorie intake to 600 to 700 calories per day for 5 days in one month. In those who are wanting to do this just for good health, the FMD increases stem cells and elongates telomeres. This postpones the aging process and keeps a person younger for longer. At the same time, it delays the onset of cardiovascular diseases.

Telomeres are Important

In the first place, Dr. Joseph Raphaele reviewed why telomeres are important at a Conference in Las Vegas in December 2019. This was at the 27th Annual World Congress on Anti-Aging Medicine in Las Vegas from Dec. 13 to 15, 2019. The actual title of his lecture was: “Telomeres in 2019; clinical developments and cutting-edge applications”.

Notably, Dr. Raphaele reviewed how various animals have quite different life expectancies. First, the Aldabra giant tortoises, for instance can live up to 152 years. Second, the house mouse can at the most live up to 6 years, but its predator, the cat lives up to 38 years. Finally, humans can live up to 122.5 years.That is to say, the average mortality rate doubling curve of man is 8 years. Dr. Raphaele introduced the terms “lifespan” and “health-span”.

Lifespan versus health-span

The first thing to remember is that our lifespan is defined by the number of years we live. On the contrary, the health-span is defined by the number of years you do not have any disease and your physical and mental health are good. Dr. Raphaele explained that for the most part the body’s organs have a limit of functioning after 80. For this reason the kidneys, the maximum heart rate, the maximum breathing capacity and the maximum work rate (oxygen uptake) all decline after the age of 80. It is important to realize that in 1961 Dr. Leonard Hayflick showed that there is a limit of how often cells can divide. After 60 doublings cells in tissue culture either die or just stop dividing. The built-in molecular clock resides in the telomeres. The telomeres are the caps at the end of the chromosomes in the cell’s nucleus.

Telomeres and their function in aging

In a word, what is the function of telomeres? In essence, the telomeres protect the integrity of our genes. For the most part, they protect the chromosomes from deteriorating, prevent DNA fusion and massive instability of the genes. In addition, the telomeres allow the cells to divide in an orderly fashion, but only up to the Hayflick limits. In short, the bottom line is that telomeres prevent cells from mutations of the DNA, from senescence and from death.

Shortening of telomere length with age

Dr. Raphaele said that one of the important findings was that telomere length is shortening with age. Notably, he showed a slide similar to this. To clarify, this graph shows telomere length as a function of the lifespan in years. The telomere length is obtained by a blood test. This determines the length of the telomeres in white blood cells. At a young age it has a length of between 8 and 10 kb. kb stands for kilobase. A kilobase consists of 1,000 pairs of nucleic acid sequences. So, 10 kb means 10,000 pairs of nucleic acid sequences. Around the age of 80 people have much shorter telomeres, only 4 to 6 kb. There is an enzyme, called telomerase that can elongate telomeres by approximately 10%. But this may not be desirable as too much telomerase activation can also stimulate cancer growth.

Age changes telomere length

Dr. Raphaele explained further that a telomere loses about 100 base pairs per cell division. But there are other factors that shorten telomeres. Smoking, sedentary lifestyle, high blood pressure, stress and a low antioxidant status all can shorten telomeres. Certain congenital conditions can shorten telomeres by 28%. Dyskeratosis congenita is such a condition where 80% patients die by the age of 30 due to aplastic anemia. This is associated with bone marrow failure. 10% of these patients die from cancer. Apart from age, which shortens telomeres slowly, lifestyle factors are very important. A good lifestyle where you exercise regularly, you don’t smoke and you eat a healthy diet will slow down the shortening of your telomeres. Controlling your stress, sleeping enough hours per night and taking supplements also delays telomere shortening. Certain medications that control diabetes, high blood pressure or thyroid medication that treats hypothyroidism also delay telomere shortening.

Telomeres and shortened lifespan

Researchers could show that good lifestyle practices work by increasing telomerase to a certain degree. This results in lengthening of telomeres and translates into up to 10 years of increased life span. Jerry Shay, PhD said in 2011: “While the aging process is complex and certainly cannot be explained solely on the basis of telomere biology, there is a growing consensus that in some situations telomere biology and telomere tests may have important utility similar to cholesterol assays or blood pressure monitoring measurements.”

Telomeres are not just a biological clock inside our cells. They have a great influence on the function of mitochondria and on how many mitochondria multiply inside cells. This latter process is called mitochondrial biogenesis. In addition, telomeres regulate gene expression.

Chronic diseases associated with shortened telomeres

Here is a list of chronic diseases where all the patients have shortened telomeres.

  • High blood pressure
  • Hardening of the arteries (atherosclerosis)
  • Cancer
  • Chronic obstructive pulmonary disease (COPD)
  • Alzheimer’s disease
  • Diabetes and obesity
  • Chronic stress
  • Metabolic syndrome

Telomeres in cardiovascular disease

Telomere length was found to be shortened in those who developed a heart attack. Researchers compared the telomere length in coronary artery disease (CAD) patients to people with no history of heart attacks. In comparison to this normal group the heart attack victims had telomeres typical for people who are chronologically 11.3 years older than the healthy controls. The researchers calculated that people with telomere shortening had a 3-fold higher risk of coming down with a heart attack.

Telomere length enhancers

  1. Lifestyle changes can have positive effects on telomere length. Examples are smoking cessation, weight loss and stress reduction.
  2. Dietary changes: we know that fish oil (omega-3 fatty acids) supplements elongate telomeres as does a low-fat diet.
  3. Supplements like vitamin D3, antioxidants (vitamin C and E) and astragalus (TA-65) elongate telomeres as well. The astragalus supplement, TA-65 showed a significant elongation of telomeres after 12 months while controls lost telomere length.
  4. Exercise: in a 24-week experiment of care workers regular aerobic exercise increased the telomeres by 67.3 base pairs.
  5. Bioidentical hormone replacement in aging people: when hormones are missing after andropause and menopause, the natural hormones need replacing, or the telomeres are shortening.
  6. High cortisol levels cause telomere shortening.
  7. Human growth hormone elongates telomeres via telomerase activation.
  8. The fasting mimicking diet (FMD) was shown to extend life and telomeres as well.

Therapeutic rationale for telomere lengthening in CAD and AD

Patients with coronary artery disease (CAD) are at risk for developing heart attacks and other cardiovascular diseases. Here is an overview of many clinical trials that have been done in humans with CAD. It shows shortening of telomeres in these high-risk patients. But the review also shows that telomeres can lengthen by changing the risk factors of cardiovascular disease. Researchers were increasing the enzyme telomerase that indirectly lengthens telomeres. Both approaches prevent serious cardiovascular disease and increase life expectancy significantly. In severe cases of telomere shortening the physician can consider TERT gene therapy.

Alzheimer’s disease (AD) also is a condition where telomeres are shortened compared to normal controls. Time will tell whether TERT gene therapy is possible to prevent Alzheimer’s disease.

Telomeres are Important

Telomeres are Important

Conclusion

Telomeres are the caps of the chromosomes in our cells. In the past the word “telomere” appeared obscure and only scientists discussed this among themselves. Now we know that telomere shortening is often the reason for chronic illnesses like high blood pressure, hardening of the arteries (atherosclerosis), cancer, chronic obstructive pulmonary disease (COPD), Alzheimer’s disease, diabetes and obesity. Patients who have these conditions often have shortened telomeres in their white blood cells. Over the years we have learnt that lifestyle changes can have positive effects on telomere length. Smoking cessation, exercise, weight loss and stress reduction are elongating telomeres.

Additional factors elongating telomeres

In addition, supplements like antioxidants (vitamin C and E), vitamin D3 and astragalus root (TA-65) elongate telomeres as well. By elongating telomeres, a person can add 10 to 11 years of disease-free life to the normal life expectancy. Researchers showed that telomerase activation by human growth hormone increased telomere length without causing cancer. Dr. Thierry Hertoghe, an endocrinologist from Belgium spoke about HGH replacement in aging people on other occasions. He said that cautiously treating patients with low doses of HGH when blood tests showed deficiency, adds about two decades of life-expectancy to these patients’ lives.

Clinical Applications of the Fasting Mimicking Diet

Dr. Kurt Hong, professor of clinical medicine spoke about clinical applications of the fasting mimicking diet in Las Vegas. This was at the 27th Annual World Congress on Anti-Aging Medicine on Dec. 14, 2019. Although he spoke on various forms of fasting, he concluded that the fasting mimicking diet had the best results and was most consumer-friendly.

How we age

Dr. Hong reviewed the processes of aging. We age, because our cells experience oxidative damage and our telomeres (the end caps of our chromosomes) get shorter in time. We also age, because there are genetic mutations in our cells’ DNA and our mitochondria are aging as well. The mitochondria are the small energy packages inside the cells that give us energy. When people age, they have lost mitochondria, there is less energy that the body makes out of food and we feel chronically tired.

Above the age of 65 we are also likely to develop diseases of various organs:

  • Heart disease: 31%
  • Cancer: 24%
  • Chronic lung disease (lower respiratory disease): 21%
  • Alzheimer’s disease: 13%
  • Diabetes: 11%

Women are generally healthier than men and their life expectation is 4 to 5 years longer than that of men.

Cellular and molecular aging

Longevity researchers have done mouse experiments and human clinical trials for decades. Dr. Hong asked the question: how much longer could humans live, if we could cure cancer, heart disease, stroke and diabetes? The answer is: 13 years. But if we transfer the animal data to humans it should be 30 years of longer life. Why is there such a discrepancy? The answer is that it is easy to force good lifestyles onto animals, but humans are resistant to changes. Humans have their habits; they like to continue to smoke and eat fast food instead of switching to a healthier Mediterranean diet. Humans also resist a regular exercise program. And they do not want to hear that they should replace missing hormones with bioidentical ones. The result is that we humans will prolong our lives only by less than 50% of what we could achieve.

The concept of intermittent fasting

Dr. Hong stated, that ten thousand years ago, people did not always have enough food to eat. They were forced to intermittently fast. That did not mean that they had long life expectancies, as there was no cure for any disease. But one fact was true: the body learnt to rejuvenate itself during periods of fasting. And these longevity genes are still present in our genes. But they will only help us when we actually fast for some periods of time.

Dr. Hong reviewed what kind of fasting methods are available.

Prolonged fasting and juice fasting are not among the options. With prolonged fasting electrolyte disturbances become an issue. Juice fasting does not remove enough calories and nutrients. This, however is needed to allow the body to stimulate the longevity genes.

How fasting diets work

Dr. Hong explained that there are essentially 5 fasting diets that are effective in regulating the key nutrient sensitive pathways of IGF-1, TOR and PKA. This increases cellular protection and maintenance. It also increases activation of stress resistance pathways and removes and replaces damaged and dysfunctional cells. Finally, a fasting diet also reduces inflammation, which is often the start of disease.

A review of the 5 fasting diets

Time-restricted eating (TRE)

With TRE the person fasts for 12 to 16 hours every day. The person restricts the daily food consumption to a 4- to 12-hour window. The disadvantage is that this fast is done every day. The period of fasting may not be long enough to change the metabolism, where the above-mentioned effects take place.

Alternate-day fasting  

This is a 24-hour fast every other day with a 1:1 day eating-fasting cycle. This does not appear to be physiological and is disruptive with regard to social activities.

5:2 intermittent fasting

With this fast you fast for 2 days every week. With this 2:5 eating-fasting cycle the person fasts for 2 days every week; the other 5 days you eat as much as you desire.

Although this is effective, it can be quite disruptive to your lifestyle.

Periodic fasting

You fast for 48 to 72 hours every couple of months. This fast is socially more acceptable. It is not that often, just a couple of times in a year. The question remains whether it is effective in changing the metabolism to trigger the effects mentioned above.

Fasting-mimicking diet (FMD)

The original suggestion by Dr. Longo, the inventor of the FMD was that you should fast for 5 days once every month. Since then he has modified it and said that you can achieve similar metabolic changes, if you only fast for 3 days and do this a couple of times per year. I have done the FMD since December 2017 and I adhere to the original schedule of doing the FMD monthly for 5 days. This has provided me with more energy. It is easier to keep my body mass index in the 21.0 to 22.0 range. Dr. Hong explained that the FMD allows you to eat, but it tricks the body into acting like you are fasting. Because you are eating 500 to 600 calories per day, you are getting some fluid and nutrients, so the hunger pangs are tolerable.

More details about the FMD

Here is Dr. Hong’s summary about the FMD: “The stomach sees food, while the cells see fasting”. Dr. Hong said that the FMD is the most user-friendly method of fasting. It also has had the most scientific studies to validate that it is indeed working. Poorly functioning mitochondria and misfolded proteins are removed by a process of phagocytosis. The FMD reduces heart disease, cancer, and neurodegenerative disorders. Stem cell production also gets a boost. This promotes cell regeneration and reduces risk factors of premature aging.

Publication on the effectiveness of the FMD

A publication came out in 2017 reporting about the findings of a clinical trial regarding the FMD.

Researchers followed markers of aging, diabetes, cancer and cardiovascular disease in 100 volunteers. They underwent a FMD for 5 days on 3 consecutive months. The results were astounding. The body mass index, the fasting blood sugar level, triglycerides, total and LDL cholesterol and the CRP were all lower. CRP stands for C-reactive protein, which measures the degree of inflammation in the body. The blood pressure was also lower. Overall the 5-day FMD was a safe method with no side effects. The FMD reduced markers and risk factors of aging and age-related diseases. In doing so it prolongs life by reducing the likelihood of coming down with disease.

Who should abstain from fasting?

Dr. Hong mentioned that the FMD is not for everybody. Pregnant women should refrain from going on it, also type 1 and type 2 insulin dependent diabetics. Anybody who has a sign of an active infection (coughing, having a fever or diarrhea) should be excluded. Other exclusions are people who are underweight (BMI less than 18.5) or are malnourished (protein deficiency). Patients with heart failure and advanced kidney or liver disease should not take part in a fasting program.

Autoimmune diseases and FMD

The myelin sheath around the axon of nerve cells in the central nervous system are supported by oligodendrocytes. In multiple sclerosis (MS) patients T lymphocytes activate macrophages and B cells to produce autoantibodies. They destroy oligodendrocytes breaking down the insulating barrier of the myelin sheath. In MS patients the broken-down myelin sheath suppresses the electrical impulses transmitted through the nerve fibers. The FMD led to clinical improvements.

In a pilot study intermittent fasting changed the gut flora into a healthier flora.

This triggered the immune system in the gut to make less inflammatory T cells producing the IL-17 cytokines. There was also an increase in regulatory T helper cells.

Inflammatory bowel disease (IBM) can be improved with several courses of FMD. As the authors showed, intestinal inflammation improved with FMD. The intestinal gut flora improved with the FMD and it promoted intestinal regeneration.

Reversal of physical and functional decline

The fasting mimicking diet (FMD) has a variety of effects on the human body. Dr. Hong showed a slide where we could see that ketone bodies, cortisol and ghrelin levels are increased in the blood. At the same time glucose, insulin, leptin and IGF-1 levels are reduced. In addition, triglycerides and LDL levels are getting lower. Inflammatory markers including the C-reactive protein (CRP) are reduced as well.

Effects of the FMD on various organs in the body

A look at all of the organs shows that in the liver the ketone body production and insulin sensitivity are up. Glycogen production in the liver as well as the liver size are down.

The intestines produce ketone bodies. In the skeletal muscles the insulin sensitivity is increased, while the muscle structure and function are improved. In the brain the hunger feeling increases the release of neurotropic factors including the neuropeptide Y. Cognitive function and stress resistance increase with the FMD. The FMD reduces inflammation and oxidative stress in the brain. With respect to the cardiovascular system the heart rate drops down and blood pressure gets lower. The insulin production in the pancreas is reduced.

Fatty tissue

In fatty tissue lipolysis is up and also the production of adiponectin. This is a protein hormone involved in glucose and fatty acid metabolism. Insulin sensitivity with the FMD is also increased. On the other hand, the FMD reduces fat mass, leptin production and inflammation.

The FMD is the solution to preventing disease and prolonging your life

All of these effects lead to a reversal of physiologic and functional declines. Age-related metabolic diseases like type 2 diabetes are postponed or eliminated. The FMD prevents neuro-cognitive decline like Alzheimer’s disease. In addition, the risk of developing cancer is getting lower. In summary, the FMD improves the health-span, quality of life and can prepare you for a long life.

Clinical Applications of the Fasting Mimicking Diet

Clinical Applications of the Fasting Mimicking Diet

Conclusion

Dr. Kurt Hong is a professor of clinical medicine at UCLA. He gave a talk at the 27th Annual World Congress on Anti-Aging Medicine in Las Vegas on Dec. 14, 2019. He discussed what we could do to help patients with various autoimmune diseases like multiple sclerosis, rheumatoid arthritis and inflammatory bowel disease. It turns out that the fasting mimicking diet (FMD) is the best solution to reduce inflammation and modify  the autoimmune response from aggressive T lymphocytes. With the FMD you consume only 500 to 600 calories per day for 5 days every month. The rest of the days of the month you eat a healthy Mediterranean-type diet.

Fasting mimicking diet, the best way to treat autoimmune diseases

Dr. Hong explained in detail what cellular mechanisms are at work to achieve the modification of the immune system in autoimmune diseases. The FMD is also the solution to slow down aging in healthy people. Dr. Hong discussed clinical applications of the fasting mimicking diet fort autoimmune diseases. It is easier to prevent disease than it is to cure an illness. The FMD is an easier way, because you don’t fast completely, you only reduce your food intake to the bare minimum, but your body “thinks” that you are fasting.

Ultimately, this approach does take some effort, and it does take time to familiarize yourself with it. If patients do it for the first time, they will experience some hunger, the first and second day tend to be a hurdle! Once you make it part of a health routine on a regular basis, it is a lot easier.

Centenarians Are Positive Thinkers

Dr. Thierry Hertoghe gave a presentation in Las Vegas on Dec. 14, 2019 where he stated that centenarians are positive thinkers. This was at the 27th Annual World Congress on Anti-Aging Medicine. The topic of his talk was “Positive Psychological Attitudes of Centenarians “.

Dr. Hertoghe is an endocrinologist in Belgium. Dr. Hertoghe took an interest in people above the age of 100. He felt that these people are special people with a very optimistic outlook on life. He went on to study the literature about this topic in detail and this is what this talk was about.

The oldest man, Gustav Gerneth died at 114 years 7 days in Germany (Oct. 22, 2019). The oldest female is Japan’s Kane Tanaka at 117 years (birthday Jan. 2,1903).

So, what is their secret to age that well? Here is what Dr. Hertoghe found out about centenarians.

Attributes of centenarians

Centenarians have a will to live. They adapt to changes; they have a sense of purpose, and they stay active. Other psychological features show that they have is a positive mood and they avoid stress and anxiety. Another important attribute is self-determination. They are very sociable, have close family ties, love their relationships and often have a strong religious faith. There is a connection between their basic values and beliefs and their spirituality. Centenarians insist on their freedom and they have a feeling of youth. Centenarians have their own centenarian spirit where they can feel young or old.

In the following I am reviewing the details that Dr. Hertoghe gave. He covered 13 subtopics regarding causes of longevity in centenarians.

The will to live

It takes courage to grow old and all centenarians have this. They say “Life is worth living”. They have a certain resiliency in a world that has an obsession about youth. Despite negative experiences they had to overcome they do not give up and they enjoy life as much as they can. A Finnish study examined 400 individuals aged 75-90 and followed them for 10 years. Group 1 who wished to live less than 5 years had a mortality rate of 68%. Group 2 wished to live for 5-10 years. They had a mortality of 45.6%. The last group, group 3 wanted to live more than 10 years. Their mortality was only 33.3%. Be careful what you wish for!

Adaptability

This describes the capacity to overcome adversity and your ability to adjust. In a study of 7400 Chinese centenarians’ resilience to changes was measured with psychometric psychological tests. The majority of subjects did not qualify for being resilient. Only 9% of male centenarians and 6% of female centenarians had the resiliency where they qualified for high adaptability. This high resilience group was associated with 2%-4% lower mortality risk. They had a 36%-55% higher odds of not developing cognitive impairment and they rated themselves as being in good health and having a “good life” satisfaction. These resilient centenarians had a 7%-12% higher probability of not developing a physical disability. Short-term health decline was not associated with these high resilient centenarians.

A sense of purpose

Centenarians can still contribute to society. Tao Porchon-Lynch turned 100 in 2014. She opened the Westchester Institute of Yoga in 1982 and is still practicing yoga. There are many ways how centenarians express a sense of purpose. Males often work in their old job, but only part-time. They may help with babysitting the great-grandchildren. Others do volunteer service. Still others may enrol in a university and study what they always wanted to do.

In a 2016 publication people older than 65 were followed between February 2011 and November 2014. Those who had neither hobbies or a purpose in life did not fare well. They had a risk of mortality of 2.08-fold compared to those with a sense of purpose. Dr. Hertoghe provided 9 more references regarding studies that showed the same finding.

Remaining active

If a centenarian remains active and moves about several hours per day, the body functions are preserved. Anna Mary Robertson Moses who was known by her nickname “Grandma Moses” took up painting at age 78. She died at age 101 in 1961.

Positive emotions

One study of 54 Ashkenazi Jewish older adults (aged 98-107) compared those with positive emotions to those with negative emotions. The researchers noted that a positive attitude about life allowed centenarians to live longer.

A study involving 2282 Mexican Americans aged 65 to 99 showed that positive affect scores were a predictor for the following. Subjects with a high positive affect had a 52% lower probability of becoming physically disabled. They were 36% less likely than the negative controls to lose their walking speed. In addition, they were 47% less likely to die during the two-year observation period than their negative controls.

Nurses’ Health Study and Veterans Affairs Normative Aging Study

Two studies, the Nurses’ Health Study (NHS) and men from the Veterans Affairs Normative Aging Study measured optimism. The researchers found that those with the highest optimism scores had a 1.5-fold higher probability in women and 1.7-fold in men to survive to age 85. This was compared to a control with the lowest optimism scores. Dr. Hertoghe provided 19 more studies that showed the effects of positive emotions regarding long term survival. For brevity reasons I will not dwell on them here.

Better stress management

Centenarians avoid excessive stress and attempt to relax instead.  It has been known since the ground-breaking work by Dr. Hans Selye that stress undermines longevity. By using relaxation methods intermittently one can reduce the stress response, which normalizes the excessive ACTH production in the pituitary gland and the concomitant cortisol production in the adrenal glands.

Self-determination

Long-living people have a strong willpower and are determined to succeed with what they want. They have a sense of self-worth and self-esteem. Centenarians have concerns for others, but they also have a healthy regard for themselves. Dr. Hertoghe provided 4 references to illustrate this, but for brevity reasons I will omit them here.

Social involvement

Centenarians have an active social life. They are involved with their family, with the community including often church communities. Sociability has a 2.3-fold higher probability of survival (mortality reduced by 57% due to sociability).

Practicing religion

Those who are centenarians were often raised in religious families. They developed a strong faith in God. A common theme among centenarians is that they trust in God and believe it is His will that they lived a long life. They also believe that eventually God will call them “home” when He is ready for them. Centenarians who practice religion have a strong belief in an afterlife, which sustains them to live and they accept death when it comes. In a 2017 study 18,370 participants aged 50 and older were interviewed in 2004 and followed for all-cause mortality to 2014. Regular church attendants had a mortality that was 40% less than those who did not attend. Dr. Hertoghe provided 20 more references that showed similar findings.

Spiritual involvement

Attributes of spiritual involvement are high ethical principles, resilience and hope that everything will turn out OK. Dr. Hertoghe cited from 7 different references that the average effect of spirituality leads to a 2- to 4-fold greater survival over 17 years.

A feeling of freedom

This makes centenarians less concerned what other people think of them. Dr. Helen Langner, a psychiatrist, still does a part-time psychiatric practice at age 100. She says about a feeling of freedom: “In old age, there’s often a sense of personal freedom because there is less pressure of a career or the responsibilities of work or raising a

family. It can and should be a time for people to do the things that are important to them and a time to enjoy. “

A feeling of youth

Many centenarians are young at heart. Even though they may look physically old, they don’t feel old in their heart.

What is the centenarian spirit?

When people are older than 100 years, they often have a mix of humor and eccentricity; they express emotions openly and they are happy people. They accept the death of spouses, siblings and significant others.

By the way, humor has a strong predictive survivor value. In a study that researchers conducted over 15 years, there was a clear positive effect of humor regarding mortality. A sense of humor reduced the all-cause mortality by 48%. In women humor lowered mortality regarding cardiovascular disease by 73%. Humor reduced death due to infections in women by 83%. Men had a non-significant reduction of all‐cause mortality by 12% and a significant lower mortality due to infections by 74%.

Dr. Hertoghe cited three more publications that showed the power of humor in reducing disease and disability.

Jeanne Louise Calment 

As an illustration for humor Dr. Hertoghe introduced Jeanne Louise Calment to the audience. She was a French woman who broke the record for being the oldest centenarian in the world.  Jeanne Calment died on August 4, 1997 at the age of 122 years and 164 days. She was asked by someone: “Why do you live so long?” She replied: “Because God has forgotten me…” Next question: “How do you consider your future life?” “Very, very short”. Last question:” What do you think of your wrinkles?” “The only wrinkle I have is the one I am sitting on”.

Centenarians Are Positive Thinkers

Centenarians Are Positive Thinkers

Conclusion

Centenarians have certain attributes that make them more resilient than others who die earlier. They have a will to live, an ability to adjust, a sense of purpose and they stay active. Their psychological make-up is such that they have a positive mood and they tend to avoid stress and anxiety. They have a sense of self-determination. They are very sociable, have close family ties, love relationships with people around them, and often have a strong religious faith. Their spirituality has a connection to their basic values and beliefs. Centenarians insist on their freedom and they have a feeling of youth. They have their own centenarian spirit where they can feel young or old. But they also have humor as documented above with the oldest woman that lived. She was 122 years and 164 days old when she died in 1997.

Ketogenic Diet With Ketone Supplementation

There is a newer way to shed some pounds using a ketogenic diet with ketone supplementation. Ketosis with a ketogenic diet is difficult to achieve because it requires a lot of fat consumption and at the same time extremely low carb intake to trigger the ketogenic response. The October 2019 issue of LifeExtension magazine contained an article about a ketogenic diet with ketone supplementation. There are dip sticks with which you can test your urine for ketone bodies to verify that your metabolism has switched to ketosis. But you can also take some ketone supplements including beta-hydroxybutyrate. By adding this supplement it is easier to achieve ketosis.

Why do people think of starting a ketogenic diet?

Calorie restriction can mimic the effects of fasting. It leads to ketone production and improved energy metabolism. Your blood sugar goes down, you lose weight and diabetes becomes easier to manage. In an animal experiment with worms with the pretty name “C. elegans” researchers fed beta-hydroxybutyrate to these roundworms. They extended their lifespan by 20%.

Many who are motivated to go on a ketogenic diet hope to lose weight and others may hope to live longer. One large US study from the Brigham and Women’s Hospital, Boston, MA showed that mortality over a period of 25 years was lowest when carbohydrates were in the 50 to 55% range. In the same study when carbohydrates were replaced in ketogenic diets with animal-derived protein and fat sources, mortality increased by 18%. Meat and fat were from sources such as lamb, beef, pork, and chicken.

Problems with ketogenic diets

Physicians have had the concern that their patients on ketogenic diets tend to eat cheap fats and meats that contain trans fats. These unhealthy fats lead to premature death from accelerated hardening of the arteries resulting in heart attacks and strokes.

The alternative: a ketogenic diet with ketone supplementation

A new approach to anti-aging is taking ketone bodies like beta-hydroxybutyrate as a supplement. A publication from 2017 stated that oral ketone bodies could mimic the life extending properties of caloric restriction. The authors stated: “An exogenous ketone ester provides a new tool for mimicking the effects of caloric restriction that can be used in future research. The ability to power mitochondria in aged individuals that have limited ability to oxidize glucose metabolites due to pyruvate dehydrogenase inhibition suggests new lines of research for preventative measures and treatments for aging and aging-related disorders.”

Another publication from 2017 describes how ketones can be used as alternatives to glucose for energy. Brain cells and muscle cells in particular are very capable to utilize ketone bodies for energy. Two principal ketones are significant: acetoacetate and beta-hydroxybutyrate. The liver is involved when fatty acids are broken down and ketones are manufactured.

Ketone metabolism

Ketones provide energy without raising blood sugar levels or stimulating insulin secretion. The body requires less processing of ketones to release energy. This means that less NAD+ is used to metabolize ketones. The end result is that more NAD+ circulates in the body, which is used to repair damaged DNA and helps slow down the aging process. Ketones mimic many of the effects of caloric restriction and intermittent fasting dieting. Ketone metabolism reduces risk factors for diabetes and heart disease.

Human experiments

A 2018 study took 20 individuals aged between 18 and 35 years and tested them with an oral glucose tolerance test. Half of the subjects received a ketogenic hydroxybutyrate monoester, the other half just water (placebo group). The ketogenic group had 16% lower blood glucose levels. Their insulin sensitivity was 11% lower. The authors concluded: “These results suggest that ketone monoester supplements could have therapeutic potential in the management and prevention of metabolic diseases.”

Longevity in humans 

There has been a lot of research in the last few years indicating that sirtuins (SIR1 and SIR3) are important anti-aging genes. NAD+ needs to activate sirtuins first to make them effective. Unfortunately with the aging process less NAD+ is available, which leaves the sirtuins genes inactivated.

In rat experiments feeding of a ketogenic diet resulted in increased levels of NAD+. The researchers measured an oxidative DNA damage marker in the hippocampus of the brain. This showed much less DNA damage in rats fed a ketogenic diet when compared to controls on a regular diet.

Study of humans with Alzheimer’s disease

Another human study examined the blood of Alzheimer patients, patients with mild cognitive impairment and normal controls.  Alzheimer patients had low ketone levels in the blood as well as low 2-hydroxybutyric acid. Overall this showed that there is a change in metabolism in Alzheimer’s patients that leads to low ketone bodies in the blood on one hand and beta amyloid deposits on the other hand leading to memory loss.

A further experiment with Alzheimer’s patients showed that cognitive function improved after elevation of ketone blood levels following ingestion of beta-hydroxybutyrate.

A healthy way to raise ketones

Investigators in this human study determined whether various ketone-drinks were elevating blood ketone bodies reliably. 15 volunteers received ketone esters or ketone salts as a drink. There was a reduction of blood pH by 0.1 units using ketone esters. The ketone salts elevated the urinary pH from 5.7 to 8.5. An experiment with 16 volunteers measured the effect of having a meal before taking ketone esters. The ketone blood level showed a reduction of 33% after the volunteers consumed a meal and they took the ketone supplement afterwards. Ketone supplements lowered blood glucose, lowered free fatty acid and also lowered triglyceride concentrations. On the other hand, there was no change of the electrolyte levels. The authors said: “We conclude that exogenous ketone drinks are a practical, efficacious way to achieve ketosis.”

Ketogenic Diet With Ketone Supplementation

Ketogenic Diet With Ketone Supplementation

Conclusion

The liver produces ketones when a person is fasting or is on a ketogenic diet. However the high fat content of a ketogenic diet can lead to atherosclerotic plaques in the arteries with the subsequent developments of strokes and heart attacks. A much safer way of raising ketone bodies in the blood is by taking ketogenic supplements by mouth. Animal experiments and clinical trials have shown that oral ingestion of ketogenic substances appear in the blood stream within 30 minutes and remain there for 3 to 4 hours. The body tolerates ketogenic supplements well with no side effects.

Prevention of Alzheimer’s disease, achieving weight loss and longevity

They likely will play a larger role in the prevention of Alzheimer’s disease in the future. Ketogenic supplements may be an adjunct to weight loss diets. In addition, fatty acids metabolize into ketones, which turn into energy in brain cells and muscles. Oral ketones stimulate the formation of NAD+, which activate longevity genes (sirtuins). Older people have a hard time to metabolize glucose because of certain enzyme deficiencies. But the brain and the muscle tissue can metabolize ketones rapidly, even in older age. Unfortunately the price of such supplementation is forbidding at the present time.

Fasting Mimicking Diet For 5 Days Every Month

In December 2017 I heard Dr. Longo speak at a medical conference in Las Vegas. He suggested the use of the fasting mimicking diet for 5 days every month. I am getting into the age group where a little help from nature would not harm (I am 74 years old). I started immediately in December 2017 to do a fasting mimicking diet (FMD) for 5 days.

Effects of fasting mimicking diet

In the beginning you just notice that you are not as hungry as you thought you would be, because you do take in three mini meals of about 200 calories each, which curbs your appetite. It is also important to consume enough liquids. Please note: liquids! Not liquor! Wine, beer or any alcoholic drinks are not part of the diet. You can drink water, but, this may get boring, and you can take water with lemon, herbal teas, black tea and coffee, as long as you stay away from sugar-laced drinks.

How the FMD works

Your total calorie intake will amount to no more than 600 calories per day for the 5 days where you do the fasting mimicking diet. Your body mass index (BMI) decreases between 0.1 and 0.4 per day to a total of 0.5 to 0.9 for the 5 days. This does not seem much, but if it is accumulating every month, a person who is obese now could have a normal weight within one year. The first day of this fast may present some challenges. I found that in the afternoon I felt hungry. What helped was a hot drink( tea, coffee, clear broth). Day two was better, and from day three it has become a routine. There are  no ferocious hunger pangs, no headaches or feelings of weakness or tiredness. I am always surprised that my energy level is improving when I do the fasting mimicking diet for 5 days every month.Dr. Longo suggests not to exercise during the fast. It is obvious that this time is not suitable for half- marathons or taxing hikes, but I found that thirty minutes of aerobics and thirty minutes of weight training felt good. Listen to your body! If you feel lightheaded at any time, stop! The emphasis is on “moderate”.

Dr. Longo noticed the following findings in a mouse model as well as on humans. I summarized this before in a previous blog:

Specific results when on the fasting mimicking diet for 5 days every month

  • Obesity diminishes, because of the weight loss effect due to missing calories.
  • Diabetes: insulin resistance becomes lower and blood sugar levels drop.
  • High blood pressure reduced: many patients were able to reduce their medications or discontinue them
  • Pain conditions improve as all kinds of pain disappears, an effect for which there is no explanation at this point
  • Autoimmune diseases like MS and rheumatoid arthritis improve, likely because of the effect of increased stem cell circulation
  • Prevention of heart attacks and strokes because of reduction of LDL, triglycerides and CRP
  • Cancer cure rates improve by protecting normal cells, the bone marrow and stimulating the immune cells
  • Longevity improved in mice with a 3-fold increase of their life span. Telomere length in humans was increased. Increased stem cells will find defective areas that need repair. This effect leads to less disease in older age.

Meal samples of fasting mimicking diet

Dr. Longo developed a kit containing all pre-packaged foods for 5 days under the name “ProLon Fasting Mimicking Diet”. The package is not larger than a shoebox, and the diet is plant-based, has some nutrition bars, drinks as well as freeze-dried soups. You can argue about the nutritional value, as it has an average rating of 3.5 out of 5. It also comes in at a hefty price of 300.00 USD. In reality it is a matter of calorie-math to consume very little food. There are plenty of tables available on the Internet that tell you the nutritional value of foods, and it does not take much effort to compose your own menu.

Here is a fairly typical list of foods

Breakfast: A typical breakfast consists of 2 slices of rye crisp bread (Wasa or Ryvita) with a bit of almond butter on it, a cup of coffee and either black or with stevia and milk.

Lunch: 8 oz. of tomato soup and coffee or tea.

Dinner: A tossed salad with organic bell peppers, ½ tomato, and two thin slices of avocado, vinegar and 1 tablespoon of olive oil.

Here is an alternative meal sample:

Breakfast: Eat a nutrition bar that is based on nuts. It should not be more than 250 calories. Alternatively make your own! Have tea or coffee.

Lunch: 8 oz. of homemade vegetable soup without the addition of pasta or beans.

Dinner: Miso soup and 4 rice crackers, alternatively a small tossed salad with olive oil and vinegar.

Results of fasting mimicking diet for 5 days every month

Here are typical results that I found over several months. I am using body composition scales every day to measure my weight, body fat percentage, visceral fat percentage, muscle percentage, calories burnt and the BMI.

One month the BMI went from 21.9 to 21.1 during a 5-day FMD. Another month the BMI experienced a reduction from 21.7 to 21. 2. Here is a list of the some of the 5-day losses of my BMI on a couple of occasions: 0.8, 0.4, 0.9, 0.7, 0.6, 0.5, 0.7 and so on.

It is important that you are not going on an eating binge after those five days. The FMD conditioned your body to be content with very small amounts of food. Enjoy your food, but stick to moderate portions.

Discussion of fasting mimicking diet for 5 days every month

An intermittent fasting mimicking diet was shown to have a diversified positive health effect in both animal models and humans. For instance, inflammatory bowel disease improves on FMD by improving the bowel microbiota and by promoting the intestinal regeneration.

Intermittent fasting, as this article shows, can prevent age-associated diseases.

This article suggests that T-killer cells that attack cancers are promoted by the intermittent fasting mimicking diet.

A FMD in type 1 diabetic patients has been shown to restore insulin generation in islets of the pancreas of these patients. The result was an improvement of their type 1 diabetes.

More research data on fasting mimicking diet

A clinical trial with 100 subjects was undertaken by Dr. Longo and his research team. He measured markers after 3 cycles of a fasting mimicking diet for 5 days every month. They found that the FMD reduced aging markers, improved diabetes and reduced susceptibility for cancer and cardiovascular disease. In another publication Dr. Longo and co-authors describe how autoimmune diseases can be improved by the use the fasting mimicking diet for 5 days every month.

Another publication by Dr. Longo describes that “age-related disorders including diabetes, cardiovascular disease, cancers and neurological disorders such as Alzheimer’s disease, Parkinson’s disease and stroke” can be prevented by fasting mimicking diet for 5 days every month.

Even cancer prevention and cancer treatment can be helped by the fasting mimicking diet.  The FMD makes chemotherapy more tolerable.

Fasting Mimicking Diet For 5 Days Every Month

Fasting Mimicking Diet For 5 Days Every Month

Conclusion

I have shown that with the fasting mimicking diet (FMD) done for 5 days in every month you can lower your body mass index (BMI) by 0.4 to 0.9 units. On the long-term this helps you to keep your BMI stable and in the 21.0 to 22.0 range. Dr. Longo has researched the effect of the FMD in both mice and humans. He found that you age better with less age-related diseases. In addition, inflammatory bowel disease, autoimmune diseases like MS, rheumatoid arthritis and type-1 diabetes improve. Cancer patients who need chemotherapy tolerate it better. Their immune system also produces more killer T cells that destroy cancer cells. The FMD prevents heart attacks, strokes and cancer. Dr. Longo also has shown that there is stimulation of stem cell production and telomeres are increasing in length. Telomeres are important for longevity, which allows you to age healthier with less disease.

Can Longevity Research Make Us Age Slower?

Longevity research has done a lot of experiments, but can longevity research make us age slower?

This year an 800-page summary was published of all the longevity research that has been going on. A review of this research is in this abbreviated article.

The entire report can be found here.

In the following I like to address some of the problems of anti-aging or longevity research.

Telomere lengthening

We know that people with longer telomeres live longer than people with short telomeres. When telomeres are longer, the cells can continue to divide and function normally. When telomeres shorten there comes a point when no more cell division is possible.  At this point the cell will normally be dissolved. When it persists, there is the danger that it undergoes a malignant transformation. This can cause premature deaths. On the other hand, if enough shortened telomeres accumulate in various organs, organ failure ensues. This will also result in premature deaths.

Research in humans has shown that increased physical activity elongate telomeres. So do vitamin C, E, vitamin D3 supplementation and resveratrol. A Mediterranean diet and marine omega-3 fatty acid supplementation elongate telomeres as well. In addition higher fiber intake, bioidentical estrogen in women and testosterone replacement in men can be effective in elongating telomeres. Finally, relaxation techniques like yoga and meditation are also elongating telomeres.

Antioxidants

Many processes lead to free radicals. Free radicals are unstable atoms that may damage cells and can cause illness and premature aging. Inflammation, the metabolism of our mitochondria, radiation exposure, industrial solvents and ozone are just some examples of what can cause free radicals in our system. If we have enough antioxidants on board, there is a balance between free radicals and antioxidants. No damage would occur then. In humans the two major antioxidants present are vitamin C and glutathione. Vitamin C comes from our food. Glutathione is produced by the liver and circulates in the blood. These two antioxidants are keeping free radicals in balance.

 

Anti-inflammatories

This Harvard site explains that even food can cause inflammation in us. For instance sugar, French fries, red meat and margarine cause free radicals. Anti-inflammatory foods are tomatoes, green leafy vegetables, olive oil, nuts, fatty fish, berries and fruit. A Mediterranean diet has anti-inflammatory qualities. There are 6 anti-inflammatory supplements that are useful to know about: ginger, fish oil, alpha-lipoic acid, curcumin, resveratrol and spirulina. In addition to the above, vitamin D3 also has anti-inflammatory effects in higher doses.

Chronic inflammation can cause cancer down the road, so it is important to prevent this by eating sufficient amounts of anti-inflammatory foods and supplements.

Genetic repairs

Spontaneous mutations of DNA, mutations of suppressor genes, oncogene activation and insufficient DNA damage response can all lead to cancer. In the past there was the hope of using chemotherapy and radiation therapy as a means to influence the outcome of cancer treatment. A reinvestigation of this concept is ongoing.

More specific treatment modalities are under investigation. When more cancer can be prevented and when it is possible to cure more cancers longevity in the population will increase. Cancer has been one of the major killers over the years.

Metformin research

Metformin has been in use for decades to prevent and treat diabetes. But beyond this it also has anti-cancer activity, it prevents Alzheimer’s, prevents cardiovascular disease and may be the first anti-aging drug. A trial to this effect is ongoing.

It makes sense that a drug that treats and prevents diabetes would be a longevity drug at the same time. The fact that it also helps to prevent cardiovascular disease and Alzheimer’s disease also makes sense. Anytime you remove a chronic disease, life expectancy improves. As a result metformin will likely receive approval as a longevity drug soon.

Mitochondrial repair

The mitochondria are small organelles in each cell. The purpose of this structure is to provide energy. In normal cells there are hundred of these organelles in each cell. In heart muscle cells, brain cells and liver cells there are thousands of mitochondria in each cell to provide energy. Muscles, nerve cells and liver cells require more energy to function properly.

Two supplements have been in use for some time to support mitochondria function.

  1. Co-Q10. This supplement supports mitochondrial function. It prevents heart disease, together with vit. K2 and vitamin D3 and it keeps blood vessels open.
  2. Pyrroloquinoline Quinone (PQQ). This supplement can increase the number of mitochondria in a cell. It can also improve their functioning. With aging we know that we are slowly losing mitochondria. It is important to know that there is a supplement that can counter the aging effect and prevent further mitochondrial loss.
Can Longevity Research Make Us Age Slower?

Can Longevity Research Make Us Age Slower?

Conclusion

For centuries people were hoping to live longer. Nowadays this dream seems to become a reality. But it does not happen with one magic pill. The aging process involves multiple targets that need attention. The telomere length is one factor. I listed a number of items that will elongate telomeres, like regular exercise and a Mediterranean diet. Antioxidants and anti-inflammatories are prolonging life as well. You want to preserve the function of your genes. Research is concentrating on improving gene repair.

Metformin has been found to prolong life. This molecule might be the first longevity drug. It has been in use to prevent and treat diabetes, but it also helps to prevent cardiovascular disease and Alzheimer’s disease. Two supplements help with mitochondrial repair, namely Co-Q10 and PQQ. Because life is all about energy, it is important to have well functioning mitochondria in all of your cells. When mitochondria are functioning, your body functions at its best, and you feel well.

Gut Bacteria Crucial To Healthy Aging

New research presented at the London Microbiome Meeting asked the question “are gut bacteria crucial to healthy aging?” Marina Ezcurra, is a Ph.D. is a researcher working at the Queen Mary University of London in the United Kingdom. She uses a nematode (round worm) model to investigate various aspects of aging. Nematodes like C. elegans provide a useful model not only for genetic work, but also for the human gut flora as well. Moreover, it allows making observations about the connection between bacterial genes and aging. Coupled with the fact that the worm has such a short lifespan, the researchers can test bacterial genes, the aging of the worm and get meaningful results in short order.

It seems like one of the research objectives was changing the nematode’s gut flora and observing life expectancy and age-related diseases.

Pathological versus healthy gut bacteria composition

Dr. Ezcurra did a couple of experiments with the nematode C. elegans as a model. She could show that the worm’s gut bacteria composition mattered. First of all, if there was a pathological composition of the gut flora, the worm did not turn as old and there were various age-related diseases that developed. Secondly, they were very comparable to human age-related degenerative diseases like Alzheimer’s disease.

Another senior author researched how genes of gut bacteria influence life expectancy

Meet Dr. Meng Wang, associate professor of molecular and human genetics, Baylor College of Medicine in Houston, TX. He did extensive genetic research on C. elegans. He used this model, because C. elegance lives only 2 to 3 weeks. This animal model is easy to manipulate. For instance, he studied the gut bacteria composition. This link explains that he tested about 4000 E.coli bacteria with various gene defects. 29 E.coli strains when deleted, increased the worms’ lifespan.12 bacterial mutants among those prevented cancer and amyloid-beta, found in Alzheimer’s disease. Some mutant bacteria caused longevity by acting on processes linked to aging.

Colanic acid is an important anti-aging factor in C.elegans

Dr. Wang joined Dr. Christophe Herman, associate professor of molecular and human genetics at Baylor, for further research. It turned out that one of the keys to longevity of the nematodes were the mutant bacteria in the gut over-producing the polysaccharide colanic acid. This allowed the nematodes to live much longer. The researchers could show further that fission and fusion processes with regard to mitochondria are important. Mitochondria are the energy packages in cells and these processes are regulated by the presence of colanic acid. As a result, if your gut has good bacteria you can grow old and escape Alzheimer’s disease and cancer.

Dr. Meng Wang said: “Of the nearly 4,000 bacterial genes we tested, 29, when deleted, increased the worms’ lifespan. Twelve of these bacterial mutants also protected the worms from tumor growth and accumulation of amyloid-beta, a characteristic of Alzheimer’s disease in humans.” 

Creating longevity with metformin, a diabetic drug

Physicians have known for some time that metformin stimulates longevity genes. This is the reason why diabetics on metformin live longer than diabetics on insulin. Dr. Ezcurra mentioned on 24 October, 2018 in her talk at the London microbiome Meeting that she had done experiments with C. elegans and metformin. Metformin reduces the risk of cancer and increases longevity in C. elegans as well as in mice (other experiments). Currently there is a clinical trial going on that investigates anti-aging under the influence of metformin in older people.

Effects of metformin on anti-aging

Metformin has the potential to target diabetes, cancer and Alzheimer’s pathologies all at once.

The anti-aging effect in humans with metformin involves the gut bacteria. Dr. Ezcurra says that this is the reason why diabetics on metformin live longer than diabetics on insulin. Metformin influences the folate bacterial metabolism of the gut flora. Other research has shown that the Akkermansia bacteria in the gut, which are good, desirable bacteria, will increase from 3-5% to 12.44% of the gut flora under the influence of metformin. Here is the discussion in detail in the following link.

Effect of gut bacteria on psychiatric diseases, obesity and diabetes

Dr. Ezcurra said that there are many studies showing that dysbiosis of the gut can lead to psychiatric diseases, Parkinson’s disease, obesity and diabetes etc.

We need to know more about whether a healthy gut flora will let us age without causing age-related diseases. Dr. Ezcurra stated: “By better understanding the links between nutrition, microbiome, and health, we can understand how the elderly can maintain their microbiome, and also help them directly by using pre- and probiotic strategies. This would help us age in a better way, maintaining health and quality of life in old age without drugs or surgery.”

Gut Bacteria Crucial To Healthy Aging

Gut Bacteria Crucial To Healthy Aging

Conclusion

The composition of the gut microbiome appears to determine whether we age gracefully or not and whether we get sick as we age or not. Everything depends on the diversity of the gut flora. There are bacteria in the gut that are good for us and also bacteria that are bad for us. Metformin has been shown to stimulate the good gut bacteria to multiply. Dr. Ezcurra is continuing her research into this. She clearly stated that it should be possible for us to age in a better way and maintain health and quality of life in old age without drugs or surgery.

Writing A Medical Book

In my 40’s when I was practicing medicine, I was dreaming about writing a medical book. This was in the mid 1980’s and I was busy seeing 30 to 40 patients a day. I would never have found the time to write a medical book at that time. I thought, perhaps I could show how patients could stay younger for longer by adopting the right life style in order to stay well. Fast forward 3 decades, and the medical book writing began. But instead of one book the project turned into 4 books. There were too many topics to cover to fit them all in one book.

Prior to writing a medical book

First of all, in 2002 I published a large website. Its structure is like a book on the Internet: Net Health Book . It contains descriptions of the major diseases, mental and physical, and their current treatment modalities. I still maintain this work. Furthermore, I started another website in 2003, a weekly blog, called “Ask Dr. Ray” . This is a compilation of interesting research. Some medical research papers can get too scientific. For this reason I translated it into easier language. The topics tend to be anti-aging topics. This blog comes out Saturdays.

Retirement hobby

When I retired in 2010 I revamped my websites. In the process the web developer suggested I should add to Net Health Book a blog (nethealthbook.com/news) where I review current health news that I find interesting. This is a weekly blog, which I publish on Wednesdays. All of this is still going on, and it gave me lots of opportunities to write and publish on a smaller scale. In addition, I finally started publishing books.

A Survivor’s Guide To Successful Aging

My first book came out with Amazon in 2014. I had joined the A4M (American Academy of Anti-Aging Medicine) in the early 2000’s. The lectures at their conferences were very open-minded and pointed out details of what one could do to delay aging and avoid premature deaths. My own experience with changing our diet in 2001, starting bioidentical hormone replacement and changing my lifestyle became topics that were part of this book. I dedicated this book “to those who are willing to work on prevention in order to achieve a longer life without disabilities”. This is still the basis of prolonging your life.

Lifestyles can be deleterious

I start out in this book describing the obesity wave and how this changes the metabolism (metabolic syndrome). I used statistics from the Framingham Heart Study to show the detrimental effects of various lifestyles on mortality. Subsequent chapters deal with food, exercise, stress and missing hormones as life-shortening factors. There is a separate chapter on vitamins and supplements. They as a group can create 5.1% longer telomeres, which translated into 9.8 years of longer life expectancy (see also a study by Dr. Xu  in the book). Subsequently it describes how a change of your lifestyle can have a positive impact. Changing your eating habits and exercise activity will make a tremendous positive difference on the long term.

Successful Aging in the Kitchen

The book ends with an appendix, written by my wife: “Successful Aging in the Kitchen”. You are presented with recipes for 7 breakfasts, 7 lunches and 7 dinners. In addition she has provided 7 healthy desserts for you. Bon Appétit!

Healing Gone Wrong, Healing Done Right

In another book, which got appeared in 2016 I gave a few examples of how famous people were failed by medicine. It started already in the past: Ludwig van Beethoven’s physicians did harm instead of healing their patient. However, this is happening now as well: physicians mismanaged the health care of Elvis Presley, Churchill, Michael Jackson and JF Kennedy. The physicians treated symptoms, but they never properly attended to the causes of the ailments of their patients. The end result was premature death in all of them. Churchill who had good genetics made it to age 90, but during his last 15 years he suffered of severe disabilities.

Treatment of symptoms will fail, treatment of causes succeed

These examples of famous people’s health problems resemble to what happens to today’s patients in various office settings. Their symptoms are mostly being treated, but their causes often not. Simply treating symptoms will not work on the long term. It did not work in the past, and it does not work now.

Other chapters in this book

Other chapters in this book deal with preventing disease, keeping a healthy brain and keeping a healthy heart. Next I discuss why food matters, followed by the health of limbs and joints. Subsequently I am discussing how to keep toxins out. The next chapter deals with how to reduce the impact of cancer. It is always important to diagnose cancer as early as possible as removal by surgery has the highest success rate at an early cancer stage. The next chapter is entitled: “Stable hormones key to health”. If any of your hormones are missing (particularly around the age of menopause and/or andropause) it is time for nature identical hormone replacement. The next chapter gives you general thoughts on anti-aging. This is followed by “supplements yes, but do not overdo it”.

Alternative treatment for ADHD

A final chapter gives you an example of an alternative treatment for ADHD, where the idea of not just treating symptomatically, but treating causes is included. References and an index are also provided for the book.

Prostate Cancer Unmasked

Furthermore, I did not intend to write this book. But in early 2016 my PSA (prostate specific antigen) level jumped from 3 to 8.6. For years it had been in the 1.5 areas, then slowly increased to 3. But 8.6 was too high for comfort! I had an MRI scan done, which showed one lesion in my left prostate, which was suspicious for prostate cancer. I was referred to a urologist at the Vancouver Prostate Centre, one of the top clinics in Canada. But I had already researched the literature and came across research by Dr. Gary Onik from Ft. Lauderdale who warned me about the pitfalls of “standard therapy”.

The conservative urologist in Vancouver

The urologist in Vancouver told me that without a positive biopsy he cannot accept that the shadow on my MRI scan would be prostate cancer. And the only way they do a prostate biopsy was by random trans-rectal biopsies. He also wanted to include me in a random clinical trial where they would compare active intervention with active surveillance. I politely declined the trans-rectal prostate biopsy and the inclusion into a trial.

Assessment by Dr. Onik

I booked a flight to see Dr. Onik in Ft. Lauderdale. His method is well researched and orchestrated.

Initial assessment

He assesses you with a rectal ultrasound and he sees the prostate on a TV screen. He said right away that I had three separate lesions, one in the left as shown on the MRI scan and two in the right lobe, which was missed by the MRI scan. False negative lesions are common on MRI scans, which can become a source of cancer recurrence.

3-dimensional prostate biopsy

The following day he booked me for a 3-dimensional prostate biopsy via the perineal approach. The perineum is easy to sterilize, so there is no risk of septicemia. A metal grid with holes for biopsy needles was used to get 96 biopsies of my enlarged prostate. For a normal size prostate, Dr. Onik said about 60 biopsy needles are normal. You don’t feel anything, because you are asleep.

Cryoablation prostate surgery

Next was the cryoablation surgery of the 3 prostate cancer lesions. This happened one month after the biopsy. I was seen at the hospital in Ft. Lauderdale. The same grid from the biopsy was used to relocate exactly where the cancer lesions were. The pathologist had confirmed them as Gleason 6 and 7 prostate cancers. This was treated with Argon sounds and frozen twice. I felt nothing, because I was under a general anesthetic. But Dr. Onik told me that everything went very well. Some cancer was too close to the neurovascular bundle, so he used the NanoKnife, an invention where nano-size holes get blasted into cancer cells, but it leaves normal tissue intact.

I needed to do self-catheterization for about one month to empty my bladder, as there was a lot of swelling from the prostate hypertrophy and the surgery. But eventually my normal water works returned.

Follow-up blood work

My follow-up PSA blood work 3 months after the surgery was down to 1.0. Prior to the surgery the Oncoblot test was positive for prostate cancer. A repeat Oncoblot test 3 months after the surgery was now negative for prostate cancer. I realize that not every physician accepts this new cancer-screening test, but I felt a lot better to know that all the cancer markers were now gone.

9 cancer treatments reviewed

In my book I described a total of 9 prostate cancer treatments and their 10-year survival statistics. None of the other treatment methods were as good as Dr. Onik’s statistics. I believe it is linked to the precision of the 3-dimensional biopsy and the surgery being done through the same grid. If you do not perform the surgery this way, you miss cancer lesions and this becomes the source of failure 10 years down the road. My book details all these alternative treatments. It also has a section on lifestyle modifying factors. I needed to write this book as a service to any man who suddenly is faced with a possible diagnosis of prostate cancer.

Unmasking prostate cancer

Like me he needs to unmask the cancer. Is it really there? How far advanced is it? Which way to safely biopsy it (definitely NOT through the rectum for fear of blood poisoning=septicemia)? What is the best method to remove it? I came to the conclusion that Dr. Onik’s method was best for me. But with the information in this book you can decide what is best for you.

Medical Questions Answered

Finally I wrote my 4th book. From more than 4400 medical questions that I have answered on the site Quora.com I selected the most popular questions for this book. The editorial board of Quora said that I own the publishing rights for my answers. The questions were rephrased without changing the meaning. I selected more than 120 questions under 44 different headings.

Here are some of the areas that are covered: Acne, the best home remedies. Aging: can it be reversed? What is the limit for a human? Alcohol: how does it affect your body? Alzheimer’s disease: which foods promote brain health? Arthritis: what can you do about osteoarthritis? Back pain: what can I do about it? Cancer: why can cancer still not be cured? There are as well 15 other answers about cancer. Depression: will my depression ever go away? Diabetes: will a 600-calorie diet help diabetes control?

Further topics discussed

Diet: I want to get rid of sugar in my diet. How can I do this long-term? Other answers about diet are included. Exercise: How useful is cardiovascular exercise? Gut disease: Is “gluten free” food healthy? Heart disease: What can I do to clean out my arteries and reduce my risk for heart disease? Hormones: Is estrogen present in the male body? Life Expectancy: What is the theoretical life expectancy of humans? Lifestyle Habits: Can good habits change your life completely? Pain: Pain relief for a headache or other pain: Aleve, Advil or Tylenol? Pregnancy: Best age for a successful pregnancy? Prostate Cancer: How dangerous is prostate cancer? Does it kill you? Schizophrenia: What complementary approach may help a patient with schizophrenia? Sleep: What happens when you go to bed late every night? And many other answers under this topic.

And the book finishes with these topics

Sugar: will I be OK living without sugar? Vaccinations: Is there a connection between vaccinations and autism? Vitamins and supplements: Are taking vitamins and supplements healthy or are they harmful? Weight loss: I am working out every day, but I am not loosing weight. What should I do? There are many more answers under this topic. Younger for longer: What are three things I can do every day to stay younger for longer?

These are only a few selections of all of the topics dealt with in this book.

Conclusion

I have reviewed briefly why I published the books mentioned above. My prostate cancer book developed out of the necessity that I had to deal with my newly diagnosed prostate cancer in 2016. I felt that the review process I went through would be good for those men who have to face a similar situation. The anti-aging book comes from my interest in anti-aging medicine. “Healing Gone Wrong, Healing Done Right” developed from the observation that physicians in the past and often even now tend to only treat symptoms. But if a cause can be found, this should be treated, as this often leads to a permanent cure.

Treating symptoms only will not improve the patient’s condition

Treating symptoms only will not improve the patient’s condition. “Medical Questions Answered” is a collection of medical topics where I answered various medical questions. It was a way for me to cover a vast array of medical topics. Some of the topics are dealt with in depth (acne for instance); others are very short. I have also two medical blogs that come out on Wednesdays and Saturdays. I hope that some of that medical information will be useful to you.

Combatting Aging using Artificial Intelligence

I found an article dealing with combatting aging using artificial intelligence. It comes from the April 2018 edition of the Life Extension Magazine.  Both of those concepts sound intriguing: “combatting aging”. It would be nice, if this would be a possibility! And “artificial intelligence” (A.I.) sounds mysterious. LifeExtension researchers have partnered up with an A.I. group, called Insilico Medicine.

Why did Life Extension engage in this project? Many people have side effects with the drug metformin, which is an old diabetes drug. It turns out that metformin stimulates anti-aging genes that help to elongate telomeres and also activate genes that prolong lives otherwise. The thought was to find out how exactly metformin protects against age-related disorders. Once researchers located the genes, they may be able to find herbs that can do the same as drugs with less side effects. Often herbs are safer than drugs.

Background regarding metformin

The FDA accepted metformin (trade name Glucophage) as the first-line therapy for type 2 diabetics, particularly if they are overweight or obese.

Side effects include gastrointestinal irritation with vomiting, cramps, diarrhea and flatulence. Even though this drug is not new, research does not fully understand all metabolic effects of metformin.

Promise of metformin as an anti-aging drug

A trial in Great Britain found that metformin has an interesting anti-aging effect. Diabetics on metformin lived longer than a control group of patients without diabetes who were not on metformin. The diabetics lived 15% longer than the controls. Further experiments with human cells and animal experiments showed that metformin is able to stimulate the mitochondria without producing as many free radicals. Free radicals cause inflammation that leads to heart attacks, strokes, Alzheimer’s and cancer. The suggestion is that all of these diseases will be suppressed when the patient is on metformin.

Mimicking the effects of metformin with three herbs

The co-operative research between the Life Extension researchers and Insilico Medicine researchers concentrated on finding data that would replace the beneficial effects of metformin with three herbs stimulating the same life-prolonging targets in human cells. This is not a small task. The following three herbs in combination cover more than 78% of the actions of metformin.

Withaferin A (found in Ashwagandha)

Weight loss

Withaferin A is a component of the life-prolonging herb ashwagandha. This herb is in use in Ayurvedic medicine because of its ant-inflammatory action; it is also anti-diabetic, anti-cancer, anti-obesity and has appetite-regulating activities. An important observation by researchers was that within 21 days of exposing obese mice to withaferin A they lost 23% of their weight. Other mice on the same diet received control solutions and did not lose weight.

Effect on neurodegenerative disease

There is a neurodegenerative condition, called Lou Gehrig disease (=amyotrophic lateral sclerosis). A group of mice that were the subjects of genetic modification to develop Lou Gehrig disease received withaferin A in their food. Compared to controls without withaferin A they had a 39% reduction of damaged proteins in their spinal cords. They also had 60% less loss of motor nerve cells. These are the nerve cells that pass on the electrical signals between the brain, the spinal cord and into the muscles. The life span of these animals that received withaferin A was 5.4% longer than control animals.

Ginsenoside (found in Ginseng)

The structure of ginsenoside is steroid-like. As the name already suggests, it is present in ginseng. The Insilico Medicine team noticed that it affects many of the same age-decelerating pathways like metformin. Ginsenoside prevents damage to the DNA and prevents loss of mitochondria, particularly in the brain and heart. In cancer cases ginsenoside also suppresses cancer stem cells, which slows down cancer growth. All in all ginsenoside reduces inflammatory changes; it also fights neurodegenerative diseases, cardiovascular diseases and cancer.

Gamma linolenic acid (present in borage seed oil)

Gamma linolenic acid (GLA) is a fatty acid. The source of it is the evening primrose plant, black currant oil or borage. The Insilico Medicine researchers found that many pathways that metformin triggers are also responding to GLA. GLA can reduce inflammation, help with adaptation to stress can modulate metabolism and participates in regulation of gene expression. GLA is also part of energy sensing in diabetes and obesity. It also can slow down cancer development.

Discussion

One has to be cognizant of the fact that LifeExtension is in the business of selling herbal supplements. It would be in the company’s interest to find an herbal combination that mimics what Metformin does. They say they have found it; so we are told in the April 2018 article of the LifeExtension magazine. But a 78% overlap of actions when the herbs were compared to metformin is not a 100% overlap.

Conflict of interest

There seems to be a conflict of interest between doing basic research on anti-aging and marketing an anti-aging product. I like to see confirmation of these findings by other independent researchers. I am not too keen to spend $1.40 every day for the rest of my life in the hopes that this herbal concoction would slow down aging. Also to state that this mix of three herbs would do the same as Metformin is a large leap of faith. At this point I am not even ready to swallow metformin just because of one trial in England that showed a beneficial anti-aging effect.

Conclusion

The old dream of finding a pill for anti-aging is alive and well. If you believe this research you are likely to buy this pill and keep on taking it for the rest of your life. But I am not so certain that either swallowing metformin or swallowing this herbal concoction will do what the researchers were hoping for. They have done some basic research with mice and rats. But they tested each of the herbs  separately, and the researchers have then mixed the herbs and claim, that this mix will do what each single herb in isolation has done. We do not know anything about the interaction between these herbs. We do not know whether there will be the same anti-aging results with the mix. All these claims are yet subject to more testing.

Proposed clinical trial

I like to see a human trial where the anti-aging pill of Life Extension is given once per day for several years (let’s say 5 years). After that anti-inflammatory indicators, telomere length and toxicity should be tested in each subject that is part of the study. If trials like this were successful in humans, I would consider buying this new supplement, but not any earlier!
