Living with the Aging Process

The following article describes living with the aging process. Older adults undergo the process of aging between the ages of 50 and 80. This is a complex process affecting various systems parallel. There are hormone factors that are particularly prominent in women during menopause. Joints are affected by degenerative changes, which can lead to total knee and hip replacements. The aging process was described in an article by Monica Jimenez at Tufts University.

What is aging?

Aging is the loss of function over time. The body is much more complex than a car, so there are more possible points of failure.  Christopher Wiley is a scientist on the Basic Biology of Aging Team who studies the role of nutrition and metabolism in aging at a cellular level at Tufts University. He said:” The fact that life works is amazing”. He went on to say: “The body tries to maintain itself and restore homeostasis(self-healing) even in the face of all this stress and all this damage. We have these really sophisticated programs for dealing with these points of failure.”

Aging goes on relentlessly

He explains the aging process this way: “It can start with something as simple as a broken molecule, one little thing that goes wrong in one cell, and then it’s like the butterfly effect,” Wiley said. “The tissue starts struggling, and then the organ, and then your entire body.”

Dr. Wiley warns about those who say physicians could make people “immortal”. “There’s definitely a misconception out there that we’re trying to make people immortal. But there is never going to be an immortality vaccine,” Wiley said. “There’s never going to be one thing that defeats all of aging. There’s always going to be another point of failure.”

Slowing down biological aging

The emphasis of research about aging is not to add chronological years. It is on biological aging and on how well our cells and tissues are functioning. Dr. Sarah Booth is the director of the Human Nutrition Research Center on Aging (HNRCA) at Tufts. She said: “Lengthening the time in which we can continue to move around, care for ourselves, and participate in social life and activities, is a worthier goal than extending years of suffering.” Many people become disabled in their last years of life, then they die. “Healthspan” is a new term for our years of freedom from disability, Booth noted.

Factors that prolong healthy aging

  1. Telomere length: One of the factors of longevity is our telomere length. Telomeres are the protective caps at the end of each chromosome. When they wear down, it leads to mistakes in the DNA copies of genetic information. There are supplements and herbs that can elongate telomeres. Exercise and the fasting mimicking diet also make telomeres longer. Older adults in good shape have longer telomeres, which stabilizes the DNA in their cells.
  2. Healthy diet: Researchers have determined that several diets are healthier than others. The Mediterranean diet is anti-inflammatory, so is the DASH diet, which was developed for people with high blood pressure. The HNRCA of Tufts is one of six organizations that got research grants recently to investigate life-prolonging diets. The amount was for $8.5 million.

Exercise and lifestyle factors

  1. Regular exercise: Over the years a lot of research accumulated data that shows regular exercise makes people biologically younger. Heart vessels have less atheromatous deposits and the brain stays younger as well. One study reported that 30 minutes of exercise daily prevents dementia.
  2. Other lifestyle factors: other factors are whether or not you are smoking (it goes without saying that you must quit). In addition, genetics (longevity gene), the environment (polluted or not), stress levels and socioeconomic class all play a factor in how fast we age. These latter points are difficult to tease apart, but they influence us globally. Target organs for aging are: the brain, heart, eyes, and bones, along with cancer, obesity, and more.

Hormone replacement 

  1. Bioidentical hormone replacement: One factor about delaying aging significantly was not mentioned in the review article by Monica Jimenez. But I am including it, because bioidentical hormone replacement is important for women who undergo menopause in their 50’s. I also mention it because men enter andropause in their 60’s. BiEst estrogen and progesterone cream make a big difference for the symptoms of menopausal women. Similarly, men experience a lot of relief with testosterone injections twice a week, when blood testosterone levels are low. If they have a lack of erections (erectile dysfunction) they may in addition need to take the “happy pill”. Sildenafil or tadalafil can treat erectile dysfunction by giving a good erection to a menopausal male. Hormone replacement can add as much as 10 healthy years to your life.

Discussion

Dr. Booth said: “We’re looking at the same question through different lenses with different tools, technologies, and perspectives. Progress in aging research is only going to be achieved by bringing together different disciplines addressing the same problem.”

Christopher Wiley added: “The biggest change I’ve seen in the past ten years is that we really are finding new, different ways of actually intervening somewhere that could potentially extend the healthy years of life, and prevent people from getting age-related diseases.” He mentioned that scientists are gradually reducing the suffering associated with aging: “What aging research is really trying to do is compress the morbidity and make it as small as possible – to alleviate suffering,” Wiley said. “I think that’s a much more humanitarian goal, and I think we’re having a lot of success with those efforts.”

Living with the Aging Process

Living with the Aging Process

Conclusion

Aging is a slow process that starts the moment we are born. But between the age of 50 and 80 we age faster. I mentioned 5 specific areas that can slow down the aging process. If somebody smokes, he/she must stop smoking. Cigarette and tobacco smoking  the biggest aging factor. The protective caps at the end of each chromosome go by the name of telomeres. When they shorten prematurely, mistakes occur in the DNA copies of genetic information. This leads to premature aging.

What keeps you younger for longer

The good news is that exercise, the fasting mimicking diet and several supplements can elongate telomeres. A healthy diet like the Mediterranean diet and regular exercise keeps the arteries open preventing heart attacks and strokes. Bioidentical hormone replacement helps to rebalance your hormones, which is important for normal cell function. In anti-aging circles they talk about life prolongation of about 10 years for hormone replacement alone. It comes down to not simply extend your lifespan, but to extend your years of healthy living without disability.

Backup your New Year’s Resolutions by looking at short-term Consequences

In the New Year it pays to backup your New Year’s resolutions by looking at short-term consequences. An article in “the conversation” explains how you can keep yourself motivated to stick to healthy habits. The alternative would be to fall back into unhealthy habits, which lead to various disease conditions. Traditional thinking centered around keeping long-term outlooks in front of your mind when tempted by the smell of doughnuts. In these cases, you think that the long-term consequences of eating doughnuts or consuming sugary drinks result in diabetes and obesity. But the smell or taste of unhealthy foods can be so overpowering that the long-term consequences of potential diseases is forgotten. This is the point when your New Years resolution may fade away in favor of falling back to unhealthy eating habits.

Think short-term to resist temptation

The new approach is to replace the thinking of long-term outlooks by short-term outlooks. The authors cited an example of 4000 participants in 7 separate studies. When the short-term consequences of anxiety and a sugar and caffeine crash were explained for caffeine containing sugary drinks, 25% of participants were able to abstain from the energy drinks in comparison to those who were informed about long-term consequences.

Another experiment

A similar experiment involved the consumption of sugar in the form of cookies. One group of participants read about the short-term effects of eating sugar. A second group read about the long-term effects of eating sugar. A third group did not get any information about the effect of sugar. There was also a “reward system” for all the participants: they had to decide between receiving a tote bag or eating cookies. Those who had read about the short-term effects of sugar were 30% less likely to choose cookies than the ones who read about the long-term effects. The ones who read the short-term effects were 45% less likely to choose the cookies than the ones who read nothing about the effects of sugar.

Verbalizing short-term consequences

Here are some thoughts that help to verbalize short-term consequences:

  • For alcohol: excessive drinking can lead to poor sleep and hangovers.
  • Fast food can make you feel bloated or give you indigestion.
  • Sugar and starchy meals: make you bloated and give you an acidy stomach, also will lead to rapid weight gain.
  • Focus on the good taste of apples and carrots. People will eat more of it and get the health benefits without mentioning it.

You can keep your goals easier when you combine them with small rewards here and there. When you have achieved one thing, you could watch your favorite TV show. Another reward could be a brief visit to the gym that makes you feel more fit. Or go and buy yourself a new pair of shorts for the gym. The authors of this article provide evidence from studies that showed that several mini rewards distributed throughout the day are more effective than big rewards at the end of the day.

Measurements of weight fluctuations

I found that body composition scales are very useful to monitor your diet intake. Here is an example how I use this device. My weights, fat% and body mass index for a number of days is listed below. The first line shows the baseline measured in the morning. On Saturday lunchtime I was invited to a Christmas family dinner. I ate more than I should have had. You can see the results on the Sunday readings: weight up, fat up and BMI up. I watched my calorie intake throughout Sunday.

Weekday              Weight (KG)                 Fat %        Body mass index

Saturday:                   63.6                           13.2                  21.7

Sunday:                     64.0                           14.2                  21.9

Monday:                    63.4                           14.3                  21.7

It took another two days (Wednesday) before the fat percentage was down to 12.9.

There is another powerful tool, Dr. Valter Longo’s fasting mimicking diet. I reported about this under this link. Briefly, once a month I eat only 500 to 600 calories daily for 5 days. This helps me to lose my body mass index from 21.8 down to 21.1 or 21.2. After that I can eat a normal diet until the next month when I do the fasting mimicking diet again. It is an easy way to keep my body mass index in the 21.0 to 22.0 range. My wife and I prepare our own 500 to 600 calorie diet with natural food.(No, you do not get much, but it can taste good!) We do not buy Dr. Longo’s expensive diet boxes.

Backup your New Year’s Resolutions by looking at short-term Consequences

Backup your New Year’s Resolutions by looking at short-term Consequences

Conclusion

Focusing on short-term goals and consequences increases the percentage of success for those who have New Year’s resolutions. You can use this for many different approaches: eating less sugar, losing weight, getting regular exercise, reducing your alcohol intake, cutting out fast food and increasing your healthy vegetable and fruit intake. I also added a description of what I do with the help of body composition scales to control my weight and body mass index. I also use Dr. Longo’s fasting mimicking diet once per month for 5-days. Since December 2017 (for 6 years) I practiced this. I find it extremely useful to maintain my body mass index in the 21.0 to 22.0 range. Medicine knows that it is important to keep your body mass index below 25.0. This will prevent heart disease, type 2 diabetes and cancer. It also helps to look forward to a healthy New Year.

Any Form of Exercise is good

Here are a few items that can prolong life; among them any form of exercise is good. This article concentrates on the exercise part in relation to longevity. A recent publication described how regular exercise prolongs your long-term survival. According to a study released on occasion of the American Heart Association’s Scientific Session 2023 there are 8 major factors that prolong life: healthy diet, physical activity, nicotine exposure, sleep health, BMI, cholesterol, blood sugar, and blood pressure.  Among this group of factors regular physical activity plays a major role to prolong your life. Researcher who studied various people found that those who neglected their physical health had a chronological age of 53, but their average biological age was 57. On the other hand, a group of fit people who engaged in regular physical exercise had a chronological age of 41 years, but a biological age of 36.

Clinical trials showing that any form of exercise is good

JAMA Internal Medicine study by Dr. del Pozo Cruz 

This study examined what the optimal amount of physical activity per week is to reduce mortality compared to an inactive population. 500,705 eligible US adults were observed for about 10 years. The abbreviations that the authors used in the study were as follows:

MPA: moderate aerobic physical activity

VPA: vigorous aerobic physical activity

MSA: muscle-strengthening activity

Results of mortality reduction with various amounts of physical activity

  • The best group engaged in more than 0 to 75 minutes of MPA combined with more than 150 minutes of VPA and 2 or more MSA sessions per week. Their mortality rate was 50% lower than an inactive comparison group.
  • The optimal combination for reduction of cardiovascular disease (CVD) and cancer mortality risk was as follows: more than 150 to 225 minutes of MPA, more than 0 to 75 minutes of VPA, and 2 or more MSA sessions per week. This reduced combined mortality of CVD and cancer by 70%.
  • The researchers stated that the adjusted mortality rates represented 50% lower mortality rate for all-cause and cancer mortality. The mortality rate for CVD mortality was 3-fold lower than for inactive controls.

Smallest amount of exercise that reduces mortality

In a study published in the European Heart Journal the authors asked how little exercise per week was enough to reduce mortality from heart disease. They found that it takes at least 15–20 min/week of vigorous physical activity (VPA) to reduce mortality from heart attacks by 16–40%. If you increased the exercise level by 50–57 min/week the mortality rates reduced even further.

Are physically active jobs healthy?

Recent research showed that people who work in physically demanding jobs are more likely to develop early cognitive impairment. This is the pre-stage of Alzheimer’s disease. 15.5 % of people who worked in high levels of occupational physical activity developed dementia. This compared to 9% risk for people whose work involved a low level of physical activity, not too much and not too little. The finding confirms the notion that there is a need for balance of physical exercise. Several publications stressed what is optimal in terms of exercise: vigorous (75 to 300 minutes per week) and moderate physical activity (150 to 600 minutes per week). People who expose themselves to these amounts of exercise live the longest and stay healthy.

Discussion

The studies discussed here showed that the right amount of exercise can reduce mortality from heart disease and cancer. However, exercise is not the only factor that can do this. It is important to combine regular exercise with a healthy diet. Your diet should consist of fruits and vegetables, whole grains, low-fat dairy products, lean proteins and limit saturated and trans-fat, added sugars, and sodium. In addition, you need enough sleep, maintain a healthy weight, manage your stress, and don’t smoke.

Any Form of Exercise is good

Any Form of Exercise is good

Conclusion

In this review I touched on the importance of regular exercise to reduce mortality from heart disease and cancer. Vigorous (75 to 300 minutes per week) and moderate physical activity (150 to 600 minutes per week) reduce mortality from heart attacks by 16% to 40%. But physical exercise is only one factor of mortality reduction. If you want the full benefit from other factors, you must quit smoking, eat a Mediterranean type diet with fruits and vegetables, whole grains, low-fat dairy products and lean proteins. Also you should limit saturated and trans-fat, added sugars, and sodium. In addition, you need enough sleep, maintain a healthy weight and manage your stress. Once you adopted this lifestyle, you live longer and you will get less diseases.

News from the Blue Zones Regarding Longevity

This article is about news from the Blue Zones regarding longevity. Blue Zones are areas where many centenarians live. Medical News Today ran a review article about Blue Zones on Sept. 23, 2023. These Blue Zones are located in Sardinia, Italy; Ikaria, Greece; Nicoya, Costa Rica; Loma Linda, California and Okinawa, Japan. Many studies looked at centenarians in these areas and analyzed what lifestyles led to their longevity. Dan Buettner summarized at a conference that only 20% of deaths in the world are due to genetic conditions. 80% of people can postpone their death date by adopting healthy lifestyles.

Factors associated with longevity

Dan Buettner called the factors that lead to prolonged life “Power 9”. The following factors must be adopted simultaneously, if you want to reach 100 years of age and more:

  • Moving naturally and regularly
  • People in Blue Zones have a purpose in life
  • Reduce stress in your life
  • Practice the 80% diet rule, which is to stop eating when 80% full
  • Adopt a plant-based diet.
  • Consume alcohol in moderation
  • Be part of a community
  • Put family first
  • keep a social circle that supports healthy behaviors

A diet for longevity

Dan Buettner analyzed the dietary habits of centenarians. He found that 90% of the diet they consumed consisted of whole food, plant-based sources and about 65% of their diet were complex carbs. Buettner noted: “The pillars of every longevity diet in the world are whole grains, nuts, greens, and other garden vegetables, tubers and beans.” For years the benefits of a Mediterranean diet were investigated and found to be life prolonging. It also emphasizes vegetables, whole foods, greens, grains, nuts and beans. The review article in Medical News Today that I mentioned above contains recommendations of how to change your diet to a healthier one.

Regular exercise

We are built in a way that requires regular exercise. When you exercise regularly, your body produces healthy HDL cholesterol that balances the unhealthy LDL cholesterol. Overall, this counteracts clogging of arteries and prevents heart attacks and strokes.

When you prevent strokes and heart attacks, you live longer.

Have a purpose in life

When you have a purpose in life, your mind is focused on what excites you. Achieving what is your dream satisfies you. Your brain releases feel-good brain hormones (dopamine, serotonin, endorphins, and oxytocin). When these hormones are released, you relax and cope with stress better. Your blood pressure normalizes, hardening of the arteries is postponed. At the same time, you prevent heart attacks and strokes. This contributes to longevity.

Reduce stress in your life

When under stress, your adrenal glands release adrenaline and cortisol. In the short term these stress hormones help you to cope better with stress. But when stress gets chronic, it weakens your immune system and increases your risk for a heart attack or stroke. It ages you faster. You can counter stress in your life by adopting stress management techniques. Regular exercise stabilizes your emotional life. You can listen to relaxation recordings or to relaxing music to calm your nerves. Developing friendships is another method of coping with stress. Here is more information on how to reduce stress in your life.

Limit alcohol consumption

In the past it was thought that small amounts of alcohol would prevent cardiovascular disease. But these studies overlooked the fact that even small amounts of alcohol can cause various cancers. So, by limiting the amount of alcohol consumption you also limit your probability of getting cancer.

Be part of a community

Many psychological studies showed that social isolation leads to health problems. It follows from this that being part of a community stabilizes your health and prevents disease. When you socialize with other people you counter stress and prevent loneliness.

Putting family first

When you care about your family, family members will care about you. Studies showed that this is an important factor in preventing disease. It even reduces mortality. Lower mortality leads to longevity.

Keep a social circle that supports healthy behaviors

Strangely enough here is another psychological factor that leads to longevity: getting support from a social circle. Being part of a social circle can create positive energy that prevents health problems.

Discussion of factors that lead to longevity

It is interesting to see that a lot of the longevity factors are psychological in nature. But physical factors are also important, like a Mediterranean diet and regular exercise. One factor that was not mentioned by Dan Buettner is the importance of preservation of hormone stability. I attended many yearly conferences of the American Academy of Anti-Aging Medicine (also known as A4M). They take place in the middle of December in Las Vegas every year. Over the years many lectures centered around hormone deficiencies. They collectively lead to premature aging and deaths. However, speakers also stressed that when you replace the missing hormones, you can reach a balance point where life gets prolonged.

Hormone replacement

One of the speakers, Dr. Hertoghe, an endocrinologist from Brussels mentioned in various talks that a lack of human growth hormone (HGH) in older age can lead to premature death. When IGF-1 levels in the blood are low, replacing the missing HGH with regular HGH injections can add 26.5 years to your life expectancy. But other hormones like thyroid hormones, testosterone in males, and progesterone and estrogen in females can prolong life when replaced after menopause or andropause (the male version of menopause).

Conclusion

Many factors contribute to longevity in centenarians. A lot of the factors are psychological in nature, like having a purpose in life or reducing stress in your life. Others are: be part of a community, put family first and keep a social circle that supports healthy behaviors. Physical factors causing longevity are moving naturally and regularly; adopt a plant-based diet; and consume alcohol in moderation. There is one important factor of longevity that Dan Buettner overlooked: your hormone balance. When we approach age 60 and beyond many people stop producing adequate amounts of hormones.

Replacing missing hormones

Anti-aging doctors have done studies showing that replacing missing hormones in proper doses will prolong life. Dr. Hertoghe, an endocrinologist from Brussels mentioned in various talks that a lack of human growth hormone (HGH) in older age can lead to premature death. When IGF-1 levels in the blood are low, replacing the missing HGH with regular injections can add 26.5 years to your life expectancy.

Sudden Cardiac Death in Athletes

This article is about sudden cardiac death in athletes. Dr. Robert A. Harrington and Dr. Manesh Patel reported from the European Society of Cardiology 2023 Congress in Amsterdam. Notably, this congress took place from August 25-28, 2023 with 30,000 participants.  Another key point is that one of the important topics was sudden cardiac death in athletes. In general, you normally assume that athletes are healthy, and their hearts would support their peak athletic activities. It is important to realize as Drs. Harrington and Patel reported that under certain circumstances athletes can suddenly die.

Bronny James, a high school basketball player was rescued from a cardiac arrest as this article shows.  Apparently, he has a congenital heart condition, which makes him more vulnerable to get an irregular heartbeat. It must be remembered that his can cause his heart to stop beating. Fortunately, he was revived at the Mount Sinai Hospital in New York. To clarify, there are a number of non-invasive procedures that interventional cardiologists use to correct abnormalities in a heart. Specifically, following such procedures the person’s heart is more stable.

Ventricular fibrillation

To explain, irregular heartbeats leading to ventricular fibrillation is one cause of death in athletes. Another key point, often there can be other underlying conditions that lead to this. Examples are a long QT interval on an ECG, a big thick heart (medical term: hypertrophic cardiomyopathy), and dilated aortas in tall people.

Success stories of reviving people and athletes with sudden cardiac death

In other words, over the years two methods showed success in rescuing athletes with sudden cardiac deaths. The first is CPR (cardiopulmonary resuscitation).   This keeps the blood flowing and delivers oxygen to the lung capillaries. Next the emergency medical team is called in who provide an automated external defibrillator to the chest. This can revive up to 100% cases of athletes with sudden cardiac deaths. The key is to do CPR right away and to have the emergency medical team use the automated external defibrillator (AED) right away.

Screening methods to prevent sudden cardiac death in athletes

With this in mind, the medical profession has started to do preventative tests of athletes. First, Italy is one of the countries that has persistently done standard screening. Physicians order ECG’s and echocardiograms. They can readily diagnose hypertrophic cardiomyopathy with these tests. Second, a new stethoscope can get sounds and some ECG signals at the same time. This helps to diagnose several abnormal cardiac conditions.

Third, another point is that there have to be enough people around a sports event who have experience in performing CPR (cardiopulmonary resuscitation). Certainly, the sooner you start CPR, the more successful is the outcome with respect to a full recovery. Next medical personnel with the AED equipment are necessary to bring the heart rhythm back to a sinus rhythm. When the patient’s heart beats normally again, the patient needs transportation to the nearest hospital for further monitoring and stabilization.

Commotio cordis

When there is a lower chest impact from a hockey puck, baseball or lacrosse ball the heart can suddenly come to a standstill. Physicians call this commotio cordis. These athletes need immediate CPR to keep them alive followed by timely administration of an automated external defibrillator. Often the heart beats normally after this. If immediate medical help is not available, these young athletes die and it becomes an upsetting newspaper story.

Sudden Cardiac Death in Athletes

Sudden Cardiac Death in Athletes

Conclusion

Dr. Harrington interviewed Dr. Manesh Patel, a cardiologist from Duke University regarding sudden cardiac death in athletes. A thump to the chest from a hockey puck or a baseball can cause the heart to stop beating. In order to save this athlete from dying bystanders have to start CPR right away. This helps to continue blood circulation and brings oxygen into the tissues. Next medical personnel apply electrode pads from an automated external defibrillator (AED) to the chest wall. One or two electric shocks are administered. This often revives the heart or converts irregular heart contractions to the normal sinus beats, and the athlete recovers. The emergency medical team transports the patient to the nearest hospital for observation and further treatments. CPR and AED in combination can save up to 100% of cases that would otherwise turn into sudden cardiac deaths.

Poor Health is Linked to Loneliness and Social Isolation

In June 2023 a new study showed that poor health has a link to loneliness and social isolation. It was also reviewed by CNN. There have been many studies in the past examining whether poor health shows an association to loneliness and social isolation. But this new study is different: it is a meta-analysis of 90 prospective studies with follow-up from 6 months to 25 years. The study included only persons age 18 years and older. There was a total of 2.2 million participants. The study specifically examined the links between loneliness, social isolation and early death.

The Meta-analysis

This new meta-analysis is significant, because with such a high number of participants the statistical strength is much better than with smaller studies. All of the 90 studies examined were prospective studies. The meta-analysis showed the difference between controls and various experimental groups suffering loneliness, social isolation and early death. The researchers identified independent risk factors of subsets among the 2.2 million subjects as discussed further below.

Loneliness

The definition of loneliness in the study was the subjective distress people feel when there is a discrepancy between the social relationships they have and what they want. If their is no fulfillment of the need for connection or intimacy in their relationships, this too can be a source of loneliness. There is increased isolation of Americans due to the increase in TV watching, spending more computer time and increase in cell phone use. This is loneliness by choice. But very few know that this can cause disease.

Social isolation

When people are under social isolation, they are under chronic stress, which translates into disease. In the statistics below it is apparent that cancer and cardiovascular mortality show a significant elevation from social isolation. In women with breast cancer there was a 51% increased mortality due to social isolation.

Findings of the study

Here are the findings form the metaanalysis. All the findings of patients suffering from loneliness and social isolation were in comparison to control groups without social deprivation.

  • There is a 32% all-cause mortality from loneliness and social isolation
  • Loneliness is responsible for a 14% increase in mortality compared to those who are not lonely
  • There is a 24% increased cancer mortality due to social isolation
  • Social isolation is responsible for a 34% increase of cardiovascular mortality
  • Socially isolated individuals with cardiovascular disease had a 28% increased all-cause mortality
  • Socially isolated women with breast cancer had a 51% increased all-cause mortality

Life style factors part of loneliness and social isolation

Turhan Canli, a professor of integrative neuroscience in the department of psychology at New York’s Stony Brook University had no involvement in the study. He said: ”People who feel socially isolated or lonely tend to have unhealthy habits, such as smoking, alcohol use, poor diet or little exercise. Having a small social network or little to no contact with the outside world can also make someone less likely to receive medical care if they don’t have anyone checking on them.”

Broadening social connections

We learnt how devastating loneliness and social isolation are for your health. It follows from this that the solution is to concentrate on broadening social connections as a preventative measure. Canli said: “Think of maintaining a social network like any other health-promoting activity: exercising regularly, eating well, looking after yourself.” Cultivate your social connections with a higher priority than in the past. Engage in new circles of like-minded people. Seek opportunities out like joining an exercise class or a discussion group.

"<yoastmark

Conclusion

Loneliness and social isolation are a real entity that threatens all of our health. A meta-analysis of 90 prospective studies (6 months to 25 years of follow-up) including more than 2 million people showed the following. There is a 32% all-cause mortality from loneliness and social isolation. Cancer mortality is up 24% due to social isolation. Socially isolated individuals with cardiovascular disease had a 28% increased all-cause mortality. Socially isolated women with breast cancer had a 51% increased all-cause mortality. There were more findings than these. Overall, this stresses the importance to cultivate your social connections, which prevents social isolation and loneliness. You will stay healthier for longer and not die prematurely.

What you Must Know about Male Hormones

Dr. Pamela Smith, an anti-aging physician gave a talk about what you must know about male hormones. She spoke on Saturday, Dec. 10, 2022 at the Sands Conference Center of the Palazzo Hotel in Las Vegas. The title was “What you must know about male hormones”. She presented 199 slides, so the following can only be a brief summary of what she said. She started by saying that the term “male menopause” goes back in time to 1944. Other terms are andropause and late onset hypogonadism.

Different testosterone levels at different ages

It is important to realize that at age 20 the blood testosterone level is around 900 ng/dL, but this declines after age 30. It is 550 ng/dL at the age of 40. At the age of 50 the testosterone level is 350 ng/dL. And at the age of 70 the testosterone level has shrunk to 200 ng/dL or less. With this in mind, there are also seasonal variations with higher levels of testosterone occurring in summer and early fall, and low levels happening in winter and early spring. A healthy male produces the following male hormones: Testosterone, 5-6 mgs/day; Androstenedione, 3 mgs/day; DHT, 0.300 mgs/day; DHEAS, 50 mgs/day; and DHEA, 15 mgs/day.

Functions of testosterone

In other words, testosterone is the male hormone responsible for the male body characteristics. Every male body cell has testosterone receptors on it. Truly, this way testosterone is involved in protein manufacture and muscle maintenance. In fact, bone formation depends on testosterone and oxygen uptake as well. It is also controlling blood sugar together with insulin. In addition, normal sperm production depends on testosterone. To clarify, testosterone also regulates cholesterol and the immune system. By all means, it also helps to improve mood, is important for mental concentration and helps protect against Alzheimer’s disease. Finally, there is stimulation of platelets and megakaryocytes by testosterone, which makes blood clotting easier.

Symptoms of andropause

It must be remembered, towards the end of their 60’s many men get symptoms of tiredness, loss of energy and depression. Specifically, they may get a bad temper, present with irritability, anxiety and nervousness. Specifically, they complain of a loss of memory, loss of sex drive and libido. Certainly, their erections are getting weak or they lose them altogether. There is a decreased intensity of orgasm and they are gaining weight. All this should prompt their physician to have a total testosterone blood test done. When the testosterone level is less than 500 ng/dL the person should see their physician for replacement testosterone therapy.

Other signs of testosterone deficiency

There are other signs and symptoms of testosterone deficiency: backaches and joint pains, loss of fitness, being overstressed. In addition, testosterone-deficient males experience a decrease in job performance and a decline in physical fitness. They have bone loss, elevation of their blood cholesterol and an increased risk of heart disease. They often also have increased insulin resistance, diabetes and metabolic syndrome. Mortality in men with low testosterone is much higher than in controls with normal testosterone. Several dozens of literature references were provided to support the above statements.

Testosterone replacement and hormone balance

When a patient is on testosterone replacement, a digital rectal exam should be performed to check for the size of the prostate gland. A PSA should be done every year (in former prostate cancer patients every 3 months). PSA should stay below 4.0 ng/mL. If the PSA rises by 1.5 ng/mL in one year or by 0.75 ng/mL in two consecutive years, a urologist should be consulted to rule out prostate cancer.

Men produce small amounts of estrogens, which are important for memory function of the brain and for strong bones. Androgens and testosterone aromatize into estrogen via the enzyme aromatase in fatty tissue. There are a few reasons why aromatase increases: obesity, excessive alcohol intake, chronic inflammation and high insulin levels.

The following medications lower estrogen levels: phenobarbital, carbamepazine, trazodone, chlordiazepoxide and sulcrafate.

Side effects from elevated estrogen levels

Increased estrogen levels in males cause gynecomastia (colloquially called “beer tits”), decreased sex drive, heart attacks, strokes and benign prostate hypertrophy. Elevated estrogen levels also cause insulin resistance, rheumatoid arthritis and prostate cancer. Dr. Smith referenced all of these statements again with many literature quotations.

Dihydrotestosterone (DHT)

This metabolite of testosterone is 3-times stronger than testosterone. It is formed from testosterone by the enzyme 5-alpha reductase. It is responsible for the male-specific characteristics, the male genitalia and the prostate gland. Low levels of DHT cause reduced sexual function, decreased libido and weakened muscle function. On the other hand, elevated DHT causes male pattern baldness, hirsutism and benign prostate hypertrophy (BPH). There are two 5-alpha reductase inhibitors, namely finasteride and dutasteride, that clinicians use to lower elevated DHT levels. This can reduce the risk of prostate cancer by about 50%. Dr. Smith provided many literature quotations to support these statements.

Testosterone replacement therapy

Based on more than 3 dozen literature quotations Dr. Pamela Smith outlined the following:

  • Most men tolerated transdermal testosterone application very well.
  • Erectile dysfunction affects 1 in 5 older men.
  • Erectile dysfunction in association with low blood testosterone and low libido responds to transdermal application of testosterone very effectively.
  • It may take 14-25 weeks before transdermal testosterone treats erectile dysfunction successfully, more than 50% of men respond to this.
  • Testosterone replacement prevents beta amyloid precursor protein production, which increases memory and decreases the risk of Alzheimer’s development.
  • High stress produces high cortisol levels in the blood, which affect the hippocampus, where memory is located. Testosterone is neuroprotective, and it preserves memory.
  • Transdermal testosterone decreases coronary heart disease by relaxing coronary arteries. This prevents heart attacks and strokes.
  • Testosterone decreases inflammation and lowers LDL cholesterol.

More facts about testosterone replacement therapy

  • Testosterone lowers inflammatory cytokines and stimulates interleukin-10 production. This has anti-inflammatory and anti-atherogenic actions, which prevents heart attacks.
  • There was a reduction in mortality from heart attacks in the testosterone treated group of between 66% and 92%. In addition, 30 nonfatal strokes and 26 nonfatal myocardial infarctions occurred in the control group, but none in the testosterone group. Testosterone deficient heart failure patients responded very well to testosterone replacement therapy.
  • Prostate cancer or benign prostate hypertrophy do not increase with transdermal testosterone replacement therapy.
  • A Meta-analysis showed that older men with the highest risk for prostate cancer have the lowest testosterone blood levels.
  • Type 2 diabetics with a high insulin resistance respond well to testosterone replacement therapy. They increase insulin sensitivity and lower their blood sugars. This improvement peaks after 3 months and the effect stays for 12 months.

Further facts about testosterone replacement therapy

  • Testosterone replacement is safe. It provides significant benefits for erectile dysfunction, for muscle mass, prevention of Alzheimer’s disease, prevention of heart attacks and strokes. Testosterone treatment is for males above the age of 50, there is no cut-off for higher ages. There are many controlled clinical trials spanning over 70 years, which support all of what is presented here.
  • Testosterone can’t be taken orally, because it is rapidly metabolized in the liver. Instead, patients use transdermal testosterone gel or cream. Gels are commercially available and very expensive. Compounding pharmacies can provide testosterone creams for you, which are considerably cheaper and can be dosaged according to the patient’s needs. Testosterone esters in oil are available for subcutaneous or intramuscular injection twice per week. This ensured a steady testosterone level.

Improvements after testosterone replacement therapy

  • Timing of improvements: cholesterol reduction occurs by 12 months, for triglycerides it takes 22 months. Testosterone levels take 4 to 12 weeks to normalize. Fasting blood sugars and Hemoglobin A1C come own within 3 months with further improvements by 12 months. Sexual desire and energy are back to normal within 3 to 6 weeks.
  • It is important that you go for blood tests to measure testosterone levels every 3 months initially (blood level). If the levels are stable, the physician may decide to only order tests every 6 months.

Conclusion

The goal in the aging male is to maintain optimal male hormone levels. This achieves optimal health and prevents diseases of older age. First, it is important to preserve his erections, but at the same time testosterone replacement therapy prevents Alzheimer’s disease and memory loss. It also prevents heart attacks and strokes. Testosterone helps to preserve muscle mass. Hormone replacement therapy keeps lipids like cholesterol and triglycerides under control. Testosterone replacement reduces blood sugars and prevents type 2 diabetes mellitus. Replacement therapy also reduces elevated insulin levels. The end result is that testosterone replacement therapy maintains the health of the aging male.

Erythritol is Linked to Heart Attacks and Strokes

A recent publication found that erythritol is linked to heart attacks and strokes. The study from the Cleveland Clinic was published Jan. 19, 2023 in Nature. It showed that people with diabetes had a 2-fold risk of getting a heart attack or stroke. Researchers measured the highest concentration of erythritol in their blood versus a control group with no erythritol in it. The study further showed that erythritol causes platelets to form clots, which could break of and travel to the heart or brain vessels. This triggered a heart attack or stroke. Dr. Stanley Hazen, director of the Center for Cardiovascular Diagnostics and Prevention at the Cleveland Clinic Lerner Research Institute said: “We never expected this. We weren’t even looking for it.”

Erythritol is what causes heart attacks and strokes

What the research team was looking for was “find unknown chemicals or compounds in a person’s blood that might predict their risk for a heart attack, stroke or death in the next three years. “This is how erythritol was identified as a risk factor.

Erythritol is a sugar alcohol

Like sorbitol or xylitol, erythritol is a sugar alcohol, which occurs in many fruits and vegetables. Erythritol has less laxative effect than some of the other sugar alcohols. It tastes like sugar and adds bulk to any stevia-based sweeteners. These are the reasons why it became the preferred zero calorie sweetener of the industry. Also, in a mixture it diluted the pronounced sweet effect of stevia, but added the crystalline texture appearance like sugar to the sweetener. This is what the consumer expected of a sweetener.

The clinical trials showing there is a link between erythritol and heart attacks as well as strokes

One group of patient’s tests were 1,157 blood samples from people at risk for heart disease collected between 2004 and 2011. Another batch of blood samples came from over 2,100 people in the United States and an additional batch from 833 samples gathered by colleagues in Europe through 2018. 75% of the participants in all three populations had coronary disease or high blood pressure, and about 20% had diabetes. Over 50% were male and in their 60’s and 70’s.  All of those samples showed the following. Higher levels of erythritol showed a correlation to a greater risk of heart attack, stroke or death within three years.

Blood coagulation

Our blood has a delicate balance between coagulation from clotting factors and platelets on the one hand and fibrinolysis, which counters clotting, on the other hand. This ensures that we are not spontaneously bleeding and also not getting clots from hypercoagulation. The researchers found that it is this balance, which erythritol disturbs. Dr. Hazel said: “But what we’re seeing with erythritol is the platelets become super responsive: A mere 10% stimulant produces 90% to 100% of a clot formation”. This was the reason for the higher heart attack and stroke rates in the higher levels of erythritol in the blood.

Erythritol levels checked in healthy volunteers

The last part of the study involved tracking blood tests of erythritol in 8 healthy volunteers. They drank beverages containing 30 Grams of erythritol, which is the amount many Americans consume. According to the National Health and Nutrition Examination Survey, which examines American nutrition each year 30 Grams is the average daily consumption of Americans. The researchers took blood tests of erythritol for the next 3 days including tests of clotting risks. Dr. Hazen said: “Thirty grams was enough to make blood levels of erythritol go up a thousandfold. It remained elevated above the threshold necessary to trigger and heighten clotting risk for the following two to three days.”

Reaction of the industry

Robert Rankin, the Calorie Control Council’s executive director, an industry association, wrote in an email: “The results of this study are contrary to decades of scientific research showing reduced-calorie sweeteners like erythritol are safe, as evidenced by global regulatory permissions for their use in foods and beverages.” But this seems to be a lame excuse. The platelet clotting effect of erythritol simply was not what the FDA expected or tested for. The same was true for other regulatory bodies when they released it as safe. I have drawn my own conclusion and thrown out all sweeteners I had in my possession that contained erythritol.

"<yoastmark

Conclusion

Sometimes studies come out of the blue, which change our everyday practice. One of these studies is Dr. Stanley Hazen, director of the Center for Cardiovascular Diagnostics and Prevention at the Cleveland Clinic Lerner Research Institute. He showed that erythritol as an artificial sweetener is not harmless as previously thought of.  This included the FDA as a regulatory agency, which labeled erythritol as GRAS (=generally recognized as safe). Now new evidence of clinical studies showed that erythritol is responsible for a twofold risk of heart attacks, strokes or death in the next three years. Dr. Hazen included all kinds of controls and also fed healthy volunteers erythritol. No matter how he looked at it, the risk remained.

Erythritol causes clots, which cause heart attacks and strokes

In animal experiments he could also show that erythritol caused platelets to stick together and cause clot formation. These clots could travel into the heart and brain vessels and cause heart attacks and strokes. For any consumer it is the most sensible approach to NOT use any sweetener that contains erythritol. This involves reading product ingredients before you buy any sweetener. Assuming that products are harmless, when the label reads “Stevia” is a fallacy! In numerous products the ingredient list will show the word “erythritol”. Buyer beware!

What Electronic Cigarettes Do to You

A review paper of Canadian researchers showed what electronic cigarettes do to you. They can be an effective smoking cessation aid for motivated smokers who eventually want to quit. But when people continue to inhale electronic cigarettes, their use can cause heart attacks, strokes, high blood pressure and increased heart rates. With regard to the lungs electronic cigarettes can cause vaping-associated lung disease, obstructive pulmonary disease, asthma and chronic cough. A literature review showed that e-cigarettes are less harmful to the heart and the lungs than smoking combustible cigarettes.

Increased use of e-cigarettes in younger people

In Canada the 2017 Canadian Tobacco, Alcohol, and Drugs Survey, which included all ages, found that 15.4% tried e-cigarettes. But among adolescents between 15 to 19 years old 22.8% were using e-cigarettes. For young adults aged 20 to 24 the figure of e-cigarette users was 29.3%. In addition, there was a significant increase of Canadian adolescents aged 16 to 19 from 29.3% in 2017 to 37.0% in 2018. Data from the US shows similar trends. E-cigarette use among US high school students increased from 11.7% in 2017 to 27.5% in 2019.

Some facts about e-cigarettes, cigarette smoking and smoking cessation

  • First, researchers noted that the smoking of e-cigarettes has a 3.62-fold risk of leading to subsequent cigarette smoking.
  • Second, a UK study found that when people used e-cigarettes for smoking cessation, 80% of the e-cigarette group were still smoking e-cigarettes after 1 year. In contrast, only 9% of those who used traditional nicotine replacement therapy (Nicorette etc.) to quit smoking were still using nicotine replacement after 1 year.
  • One study compared heart attack rates in a group of regular cigarette smokers and compared this to e-cigarette smokers. Cigarette smokers had a 2.72-fold higher heart attack rate than non-smokers, while e-cigarette smokers had a 1.79-fold heart attack rate compared to non-smokers.

Effect of e-cigarette use on heart and lung disease

Several studies looked at the relationship between e-cigarette use, heart attacks and strokes. There was a 1.4-fold higher incidence of coronary artery disease in e-cigarette smokers in comparison to non-smokers. The e-smokers had a 1.71-fold higher stroke incidence and 1.59-fold higher heart attack rates. In a large metaanalysis done with e-cigarette smokers, researchers noted the following facts: Electronic cigarette smokers were compared to non-smokers. Researchers noted a 2.27-fold increase of the heart attack rates in e-cigarette smokers. There was a 2-fold elevation of the systolic and diastolic blood pressure in e-cigarette smokers.

Switching from cigarette smoking to e-cigarettes

Patients who switched from tobacco smoking to chronic electronic cigarette use had a 7-fold reduction of their systolic blood pressure and a 3.65-fold reduction of their diastolic blood pressure. The researchers concluded that switching from cigarette smoking to e-cigarettes had some merit in terms of risk reduction for cardiovascular disease. But the final judgment on this is still pending. Certainly, quitting entirely from cigarette smoking is the best choice. I reported previously that e-cigarette smokers find it difficult to quit completely and if they smoke conventional cigarettes to stop that.

Effect of e-cigarettes on lungs

In addition to cardiovascular effects there is a direct effect from e-cigarette smoking on the bronchial tubes and the lungs. The vaped substances from e-cigarettes contain a lot of noxious gases that irritate the lining of the respiratory tract. This syndrome is called EVALI (electronic vaping associated lung illness). In 2019 and 2020 there was a rush of EVALI cases in the US with 2807 hospitalizations and 68 deaths. In Canada there were 19 cases of EVALI, 15 hospital admissions, and no deaths. Patients with EVALI have problems breathing, they cough and they have chest pain. Researchers suspect that vitamin E acetate and tetrahydrocannabinol are the major culprits that cause EVALI. But at this time there is no definite proof for that.

Poor quality of vaping fluid from the black market

These substances are not present in commercial e-cigarettes, but when you buy vaping fluid on the black market, it is often mixed in. Prolonged use of e-cigarettes can cause changes on spirometry, such as chronic obstructive pulmonary disease (COPD). Chronic use of e-cigarettes may cause premature onset of COPD.

What Electronic Cigarettes Do to You

What Electronic Cigarettes Do to You

Conclusion

E-cigarette use is increasing at an alarming rate among youths and persons who never smoked. The emerging evidence from researchers showed that there is a risk when you expose yourself to the smoke of e-cigarettes. There is an association of both heart disease and respiratory disease to e-cigarette smoking, but the risk is less than with exposure to regular cigarette smoke. Some researchers think that a switch from cigarette smoking to e-cigarettes could provide a viable harm reduction strategy for some smokers. But unfortunately, many continue to smoke e-cigarettes instead of quitting altogether. And in this case the risks for heart disease and lung disease remain!

How healthy are Carbohydrates?

A recent review article asked: how healthy are carbohydrates? The three food components that occur in natural food are carbohydrates, fats and protein. Among the carbohydrates it is important to distinguish between simple carbohydrates (such as sugar) and complex carbohydrates. Simple carbohydrates are readily absorbed into the blood, which causes an insulin peak. After a few hours the peak is gone, and there is a “crash”. You will know the feeling of feeling hungry just a few hours after eating doughnuts! Complex carbs like peas, beans, fruit and vegetables take longer to get digested. The final breakdown product of the digestive process is sugar as well. But this process takes longer meaning that the concentration of sugar in the blood is much lower. There is also no “crash”. The result is that complex carbs cause less insulin secretion into the blood.

Long-term effect of eating too much sugar

Integrated over several decades of life, this means that a person who constantly consumes beverages with sugar and snacks containing sugar is at a higher risk of developing type 2 diabetes. In contrast, a person who eats well balanced meals where the insulin secretion is low, will not develop diabetes and have much less hardening of the arteries. This translates into a lower risk to develop heart attacks and strokes.

The types of carbohydrates

Before I discuss the health effects of various carbohydrates, we need to look at the types of carbohydrates.

Simple carbohydrates

Table sugar is a disaccharide, which consists of one molecule of glucose and one molecule of fructose.

The enzyme amylase very quickly breaks down the chemical bond between fructose and glucose and creates these monosaccharides in the small intestine from which they are rapidly absorbed. Milk sugar is a disaccharide, which consists of a molecule of glucose bound to a molecule of galactose. Milk contains 2 to 8% of milk sugar. We have to watch these simple carbs, because they trigger insulin production and lead to accelerated hardening of the arteries, heart attacks and strokes.

Complex carbohydrates

In contrast, complex carbs are healthy, because they take some time to be digested in the digestive tract. They consist of polysaccharides, long chains of sugar molecules. Both starches and dietary fiber consist of complex carbohydrates. They often are present in vegetables and many fruit. Complex carbs slow down the absorption of their breakdown products and minimize the insulin response. Dietary fiber is the indigestible part of fruit and vegetables. It contributes to good gut health as the beneficial gut bacteria can multiply on the fibre particles.

Healthy carbs

When simple carbohydrates dominate in our food intake, we are in trouble because they are loaded with calories. Overconsumption of them leads to weight gain and obesity, to diabetes, heart attacks, strokes and even cancer. On the other hand, consumption of complex carbohydrates is healthy. We get them from eating apples, bananas, berries, vegetables like spinach, tomatoes and carrots. Other healthy complex carbs are whole grain flour, quinoa and brown rice. Black beans, lentils, peas and garbanzo beans are also healthy complex carbs. Dairy products like low fat milk, yogurt and ricotta cheese are healthy as well.

Mediterranean diet as an example of a healthy, balanced diet

In 2019 a study was published where women with polycystic ovary syndrome (PCOS) were either put on a Mediterranean diet or not. This study showed that a Mediterranean diet was anti-inflammatory, reduced insulin resistance and reduced testosterone levels in PCOS patients.  But the same is true in a general population. The Mediterranean diet is one example of a healthy, balanced diet with complex carbohydrates. It prevents insulin resistance, inflammation and hormone disbalance. Other diets have similar effects like the DASH diet, the Zone diet and the Pritikin diet.

Quantity and quality of your food intake matters

A 2018 study from India showed that it matters how many carbohydrates we consume.  On average Indians eat a diet with 65-75 percent of calories coming from carbohydrates. Many of these carbs are the unhealthy simple carbohydrates. How healthy are  carbohydrates? The authors recommended to reduce complex carbohydrates to 50-55% and to add 20-25% protein, mostly from vegetable sources and add 20-30% from fat. The fat consumption needs to include monounsaturated fats (e.g., olive oil, nuts and seeds). Among the carbs a lot of green leafy vegetables help to balance the diet. This prevents the development of type 2 diabetes, heart attacks and strokes.

The above addresses the issue of quality of food. But it is also important what quantity of food we are eating. This is where counting or estimating calories comes in. If we overeat, we will very quickly gain weight and eventually can develop obesity.

The glycemic index and glycemic load

In order to help you with the choice of right carbohydrates the glycemic index was developed.

Here is another reference about the glycemic index/glycemic load.

In table 1 towards the end of the last link you find a column designated “GI” for glycemic index. All the foods that have a value less than 55 are foods that you can eat freely.

Problematical carbohydrate foods

Baked russet potatoes and boiled potatoes are very high on the GI index list. Puffed rice cakes, doughnuts, jelly beans and corn flakes measure high on the glycemic index list. But water melons, dried dates, white bread and white rice are also items to be avoided.

You best avoid anything with a glycemic index above 55. The column to the right of GI shows you a serving size and the last column on the right the glycemic load. The lower the glycemic load per serving, the better it is for your health. The glycemic index and the glycemic load are useful concepts of helping you to sort out your diet items.

My wife and I used this in 2001 to shed weight. We both lost 50 pounds (=22.72 kilograms) each in a period of 3 months.

Fasting mimicking diet (FMD)

According to Dr. Longo intermittent fasting stimulates the stem cells of the bone marrow. This leads to new clones of lymphocytes (B cells and T cells), which are part of the immune system. Your immune system becomes stronger from this.

Dr. Longo has done detailed mouse experiments, which inspired him to develop a new diet plan. Patients would receive a fasting mimicking diet (FMD) on 5 consecutive days per month. The rest of the month consists of a normal, balanced diet. 5 days of the month the person consumes a low 600-800-calorie diet. This reduced calorie intake is enough to ensure adherence to the diet, but low enough to lead to enormous positive metabolic changes including youth-preserving stem cell stimulation.

I am following the FMD

I have followed a FMD since December 2017. It helps me to keep my weight (BMI) in the 21 to 22 range. I feel more energetic and have managed to stay in good health.

The above chapter on the FMD was previously published here.

How healthy are Carbohydrates?

How healthy are Carbohydrates?

Conclusion

Healthy eating consists of 50-55% calories from complex carbohydrates; add to this 20-25% protein, mostly from vegetable sources and add 20-30% of total calories from fat. The fat consumption needs to include monounsaturated fats (e.g., olive oil, nuts and seeds). Unfortunately, most “convenience foods” (=processed foods) are incompatible with a healthy lifestyle. They contain too much simple carbs (sugar). Many people live on 65-75 percent of calories coming from simple carbohydrates, which are too many carbs. It should be complex carbs that digest slower and that do not induce insulin resistance. The glycemic index and glycemic load are useful concepts to help you chose the right foods that keep you healthy. The fasting mimicking diet can help you to take the last few pounds off that may be difficult to shed. Weight loss and weight maintenance are possible when you choose the right foods.
