    Know Your Health; Know Your Biomarkers

    America is not a healthy nation. The US spends more on health care than any other high-income country but still has the lowest life expectancy at birth and the highest rate of people with multiple chronic diseases, according to a 2023 report from The Commonwealth Fund, an independent research group. In fact, America is ranked No. 35 out of 169 countries in terms of overall citizen health, according to the Bloomberg Healthiest Country Index. This means that 34 countries are ahead of us.

    It’s easy to see why. Nearly 60% adults in the United States have at least one chronic disease, with the most common being heart disease, cancer, diabetes, arthritis, and obesity, according to the CDC. Consequently, biomarkers — objective measures of normal or abnormal processes or conditions or diseases —really matter. These might include blood pressure, resting heart rate, blood sugar levels, cholesterol levels, and body fat percentage, for example.

    Essentially half (47%) of American adults have high blood pressure (hypertension), according to the American Heart Association. That amounts to a whopping 122.4 million people. A normal blood pressure is less than 120/80 mmHg. A blood pressure of 140/90 mmHg or more is too high. People with levels from 120/80 mmHg to 139/89 mmHg have a condition called pre-hypertension, which means they are at high risk for high blood pressure.

    Having high blood pressure puts you at risk for heart disease and stroke, which are leading causes of death in the United States. However, most people who have hypertension do not experience any symptoms. People usually discover that they have hypertension following a routine blood pressure check.

    Another all-too-common disease in the US is diabetes, which is diagnosed when a person’s A1C levels are 6.5% or higher.

    According to the CDC, 11.3% of the US population has diabetes, and 23% of adults are undiagnosed. This means that more 34% of the adult population likely has diabetes. Yet, about 90-95% of people with diabetes have type-2, which is preventable. Additionally, about 98 million American adults (more than 1 in 3) have pre-diabetes. If you get the sense that diabetes is a crisis in the US, you’re right. Having diabetes also raises the risks for other chronic conditions.

    For example, if you have diabetes, you are twice as likely to have high blood pressure. Chronic diseases are often linked.
    Diabetes is the top cause of kidney failure, causing nearly half (47%) of new cases. About 1 in 3 adults with diabetes may have kidney disease. High blood pressure is the second most common cause of kidney failure, causing 27% of new cases. In fact, 1 in 5 adults with high blood pressure may have kidney disease. Are you getting the sense that many of the most common chronic diseases are linked?

    Quite astonishingly, as many as 37 million Americans have kidney disease, meaning it affects 14% of American adults. In fact, kidney disease is the fastest-growing noncommunicable disease in the US, and it’s one of the top 10 causes of death.

    The kicker is that all of the above are preventable; it’s within our hands to heal or prevent them. But there’s more.

    High LDL (bad) cholesterol levels in the bloodstream may increase the risk of heart disease and cardiovascular events like stroke. Normal cholesterol in adults is less than 200 mg/dL; borderline high is 200 to 239 mg/dL. Yet, about 86 million US adults age 20 or older have total cholesterol levels above 200 mg/dL, according to the CDC. And nearly 25 million adults in the US have total cholesterol levels above 240 mg/dL.

    The latest data indicate that 39.6% of US adults are obese, and another 31.6% are overweight. Taken together, 71.2%, or nearly three-quarters, of American adults are either overweight or obese. This comes at a tremendous cost to our national wellbeing. Overweight and obesity may increase your risk for developing health problems, such as diabetes, heart disease, stroke, and certain cancers, according to the National Institutes of Health.

    Excess body fat is associated with high levels of LDL (bad) cholesterol and triglycerides, as well as low levels of HDL (good) cholesterol. It also impairs the body’s responsiveness to insulin, raising blood sugar and insulin levels. Excess body fat contributes to major causes of death and disability, including heart attacks, strokes, high blood pressure, cancer, diabetes, osteoarthritis, fatty liver, and depression. Yet, when it comes to health, the issue is not how much you weigh but how much abdominal fat you have. Research shows that abdominal fat is the worst of the worst because it is a major contributor to cardiovascular disease.

    Waist circumference is an indicator of the health risks associated with excess fat around the waist. A waist circumference of 40 inches or more in men, or 35 inches or more in women, is associated with health problems such as type 2 diabetes, heart disease, and high blood pressure. Ideally, everyone should aim to keep their waist measurement less than half that of their height, according to scientists. That means a 6ft (72 inch) tall man should aim to keep his waist less than 36 inches, while a 5ft 4in (64 inch) woman should keep hers under 32 inches.

    Metabolic syndrome is a cluster of conditions that increases the risk of heart disease, stroke and diabetes. Metabolic syndrome includes obesity, high blood pressure, high blood sugar, high triglycerides, and irregular cholesterol levels. The risk of metabolic syndrome increases with age, and about 1 in 3 adults have metabolic syndrome.

    Heart disease remains the leading cause of death in the US, as it has been for the past 100 years. Stroke is the fifth leading cause of death. Together, they claimed more lives in 2021 in the U.S. than all forms of cancer and chronic lower respiratory disease combined. High blood pressure, high blood cholesterol, and smoking are key risk factors for heart disease. Yet, diabetes, overweight and obesity can also put people at a higher risk for heart disease.

    The links between all of these chronic diseases is striking. Having high blood pressure puts you at risk for heart disease and stroke. If you have diabetes, you are twice as likely to have high blood pressure. Yet, people with high blood pressure usually have insulin resistance and have an increased risk of developing diabetes compared to those with normal blood pressure. So the relationship between diabetes and high blood pressure is a two-way street. Diabetes is the top cause of kidney failure. High blood pressure is the second most common cause of kidney failure. High LDL (bad) cholesterol levels in the bloodstream may increase the risk of heart disease and stroke. Overweight and obesity may increase your risk for developing a wide array health problems, such as diabetes, heart disease, stroke, and certain cancers.

    Link after link after link. The connection between chronic conditions is stark.

    Yet, being thin doesn’t necessarily mean that you’re healthy. Thin people might still have cancer, diabetes or heart disease, for example.

    Health is comprehensive and encompasses a number of factors including nutrition, exercise, sleep, stress levels, lifestyle choices, and more. Weight is just one small piece of the puzzle and should never be used as the sole indicator of overall health.

    Wellness requires us to think holistically and address all indicators of health. Obsessing and stressing over one factor, such as weight status, can stunt progress and lead to decreased mental wellbeing.

    It’s important to recognize that medical interventions contribute less than 10% to overall health. Meanwhile, nutritional status accounts for a remarkable 80%. Nutrition addresses the root causes of diseases, whereas drugs often only alleviate symptoms. What we eat really matters… a lot.

    We know that exercise certainly improves health and wellness. Yet, a staggering 80% of US adults and adolescents are insufficiently active, according to the Journal of the American Medical Association. What’s more, those leading sedentary lifestyles face a 20-30% higher risk of mortality compared to those who participate in at least 30 minutes of moderate exercise most days of the week, according to the World Health Organization.

    Numerous studies show that consistent exercise decreases the risk of cardiovascular disease, type 2 diabetes, many cancers, cognitive decline and mental illness. Meanwhile, a sedentary life is associated with an increase in cardiometabolic disease and shortened lifespans.

    While there are many reasons that people exercise, in my view it shouldn’t be about having the best butt or bigger biceps; it’s about being a happier, more fulfilled, more self-satisfied person. Everyone recognizes that exercise can change your body, but it can also change your mood, your attitude, and even your mind.

    Wellbeing is not just the absence of disease or illness. It’s a complex combination of a person’s physical, mental, emotional, and social health factors. Wellbeing is strongly linked to happiness and life satisfaction. In short, wellbeing could be described as how you feel about yourself and your life.

    Researchers agree that health-related quality of life is multi-dimensional and includes domains that are related to physical, mental, emotional and social functioning, and the social context in which people live. That said, loneliness and social disconnectedness are two of the greatest challenges of the modern era. Social isolation and loneliness are now considered demonstrated risk factors for depression and cancer. Our social connections, or lack thereof, really affect our health.

    Loneliness takes a toll on our health. It can lead to high blood pressure, and an increased risk of cardiovascular disease and stroke. Loneliness has been linked to the progression of Alzheimer’s, raising the likelihood of dementia by 40%. And it can also double the risk of Type-2 diabetes. One study found that loneliness can be as much of a long-term risk factor as smoking. As a consequence, chronically lonely people tend to have an 83% higher mortality risk than those who feel less isolated.

    Brigham Young University researchers have revealed that loneliness is deadlier than obesity and should now be considered a major public health hazard. They discovered that lonely people had a 50% increased risk of early death, compared to those with good social connections. In contrast, obesity raises the chance of dying before the age of 70 by around 30%. Humans are social animals. We need community, we need friends. While solitude may be nice sometimes, loneliness isn’t.

    Research also shows that mindset really matters when it comes to health, and it can even extend your life. A classic study found that people who were optimistic about aging lived seven and a half years longer than those who had negative perceptions of it.

    The takeaway is that our health is mostly in our own hands. We can be proactive and we can largely control our own destiny. We are not fated to ill health, even if our parents or grandparents had specific diseases. Most of the diseases that modern Americans suffer from are lifestyle disease, meaning they’re the result of the way we live and the choices we make.

    We can make better choices to improve our health, the quality of our life, and even our life expectancy. We also need to remember that stress reduction and social connection play a big role in our wellbeing. We can do better, and we must do better. Our very lives depend on it.

    It’s preferable that your doctor tells you that you look better on the inside than on the outside. Your biomarkers really matter, and you should know them.

  • Honor Your Body Clock, Create Circadian Alignment

    Honor Your Body Clock, Create Circadian Alignment

    Scientists have isolated the body-clock genes that control 24-hour light-dark circadian rhythm, and it’s now known that every cell in the body has a synchronized clock. 
     
    The 2017 Nobel Prize in Physiology and Medicine was awarded to three scientists who discovered the body clock gene and its critical role in metabolic function. In a world of 24/7 non-stop chaotic eating, relentless stress, continuous screen-gazing, sedentary lifestyle and sleep deprivation, time has become irrelevant. These constant 21st century disruptions of the powerful cellular body clock cycles (aka, circadian rhythm) are wreaking life-threatening havoc on mental and physical health, resulting in obesity, metabolic syndrome, cancer and diabetes.
     
    “We didn’t realize at the time that this clock would be represented all over the body in many different tissues and control so many different biological processes that we go through every day,” says Michael Young MD, 2017 Nobel Laureate in Medicine and Physiology. “It left us with the understanding that our whole bodies are rhythmically active.”  
     
    Circadian Alignment is when the central and peripheral clocks are aligned: bright light during daytime, sleep at night, and food intake during daytime. Circadian Misalignment is when the central and peripheral clocks are misaligned: light at night, sleep during daytime, and food intake at night.
     
    This misalignment has become normalized. According to a recent study of the eating habits of more than 34,000 U.S. adults, nearly 60 percent said it was normal for them to eat after 9 p.m. 
     
    Yet, time-restricted eating (12-16 hours of non-eating) has proven to be the best match to our circadian clocks. This means we need to eliminate nocturnal eating. We should stop eating by 6-7pm and not eat again for at least 12 hours (14 hours is the sweet spot).
     
    Our bodies have evolved to process nutrients during the day, and to conserve energy at night. The body uses energy to repair all of its systems at night, while we sleep. Disrupting that natural rhythm can cause problems.
     
    Several studies have found, for instance, that eating dinner within three hours of bedtime may worsen heartburn or acid reflux symptoms. And limited research has suggested that eating one to three hours before bedtime is associated with more disrupted sleep.
     
    The most intriguing research on late-night eating, however, has focused on its relationship with body weight and metabolic health.
     
    In one 2019 study of nearly 900 middle-aged and older U.S. adults, researchers at Brigham and Women’s Hospital in Boston found that those who consumed roughly 100 calories or more within two hours of bedtime were about 80 percent more likely to be overweight or to have obesity than those who did not eat during that window. Researchers have found similar results in adults in Sweden and Japan.
     
    And in a 2023 study of more than 850 adults in Britain, those who regularly snacked after 9 p.m. had higher levels of HbA1c, a marker for diabetes risk, and greater spikes in blood sugars and fats after daytime meals than those who did not typically consume late-night snacks.
     
    Research has also found that carbohydrates consumed in the evening result in greater blood sugar spikes than those consumed earlier in the day. That is in part because melatonin, a sleep-promoting hormone that increases in the evening, dampens the secretion of insulin, which regulates blood sugar levels. Elevated blood sugars could eventually damage blood vessels and increase the risk of developing high blood pressure and Type 2 diabetes.
     
    Research suggests that it’s best to avoid eating for three to four hours before your usual bedtime. We should be eating during an 8-12 hour window, allowing 12-16 hours for regeneration. We should also be sleeping for 7-8 hours each night. 
     
    A regular bed time is critical for your health and wellness, as is a regular waking time. Additionally, sleeping too long can affect your ability to fall asleep that night. After a good night’s sleep, most people need to be awake around 16 hours before they feel sleepy again.
     
    Going to sleep between 10:00 pm and 11:00 pm is associated with a lower risk of developing heart disease compared to earlier or later bedtimes, according to a recent study by the European Society of Cardiology. Early or late bedtimes may be more likely to disrupt the body’s circadian clock, with adverse consequences for cardiovascular health, according to the study’s authors.
     
    The incidence of cardiovascular disease was highest in those with sleep times at midnight or later (25% higher risk) and lowest in those with sleep onset from 10:00 to 10:59 pm. There was also a 24% higher risk for falling asleep before 10:00 pm. Yes, the body clock is that precise and sensitive. 
     
    Humans are not nocturnal animals; we are diurnal. We need to honor our innate body clock by eating and sleeping in a manner that naturally suits us and promotes health.
  • What Is Your Body Type?

    What Is Your Body Type?

    One’s body type, or somatotype, describes their body composition or the amount of muscle and fat their body tends to comprise. There are three body types — endomorph, mesomorph, and ectomorph — and each is related to overall body composition. 
     
    Endomorphs have bodies that are rounded and soft (think apple or pear shaped), with shorter, thicker arms and legs; mesomorphs are athletic and muscular; and ectomorphs are slender, with thin arms and legs. 
     
    More specifically, endomorphs are stocky, with a larger midsection and hips. Their bodies hold more fat, which is easy to gain and difficult to lose. Endomorphs have a slower metabolism and are more likely to be sedentary. Though they may be heavy and carry lots of body fat, endomorphs can be quite strong. Participants in strongman competitions are likely to be endomorphs.  
     
    Mesomorphs have athletic, muscular bodies, with broad shoulders and narrow waists. They have a higher metabolism and can gain muscle and lose fat fairly easily. Most athletes in sports that require speed, strength, power and coordination tend to be mesomorphs. Most people who exercise would like to have a mesomorphic body, whether that’s realistic or not.
     
    Ectomorphs have narrow shoulders and hips, with longer limb segments. They are the classic ’skinny’ body type. They have a very high metabolism that makes it difficult to gain either muscle or fat. Ectomorphs seem to able to eat almost anything and everything without gaining an ounce. As athletes, ectomorphs are likely to be distance runners. However, they aren’t likely to excel at sports requiring power and strength. 
     
    However, most people are some combination of these body types. For example, one might be a cross between an endomorph and a mesomorph, or a cross between an ectomorph and a mesomorph. For each of these body types, an appropriate diet makes a big difference in the results they will get from a workout program.
     
    One study, published in the National Center for Biotechnology Information, found that men were most likely to be endomorphic/mesomorphs and women were most likely to be mesomorph/endomorphs. Another study of men and women, also published in the National Center for Biotechnology Information, found that the average distribution of somatotypes is 51.6% endomorphic/mesomorphs, which was by far the highest percentage found in the study. In fact, 65% of men in this study were endomorphic/mesomorphs. Next up were mesomorph/endomorphs (17.1% ), and mesomorphic/endomorphs (16.7%). After that, the percentages for each cross type fell into the low single digits (6.1% balanced mesomorphs, and 3.0% ectomorphic/mesomorphs). The study also showed that somatotype classification is not static and can shift over time. So, we can eat and train in a way that will change our bodies. 
     
    Those who are predominately ectomorphic need a diet and training program that focuses on protein intake and muscle mass gain. Since it is difficult for these people to put on mass and maintain it, their workouts should focus on building muscle (hypertrophy) and strength. There should be less focus on cardiorespiratory training and calorie burning. Ectomorphs need to focus on getting adequate calories and high-quality nutrition that will help them gradually gain mass. Ectomorphs need high levels of protein in the range of 1.2 to 1.6 grams per kilogram body weight per day, which is optimal for muscle growth. Since ectomorphs can eat virtually anything without gaining weight, they need to be careful of eating junk foods/calories that are absent nutrition. Quality still counts for ectomorphs. Fats and carbohydrates can be eaten in copious amounts, but the nutritional value of everything eaten still matters, even if fat gain is not an issue. Meals should be eaten frequently throughout the day. Protein shakes can be a helpful way to get adequate protein and calories. 
     
    Those who are primarily endomorphic need a diet that focuses on reduced calorie intake, limited carbohydrates, higher protein, and frequent training sessions to stimulate metabolism. Workouts that focus on aerobic capacity and cardiovascular function should be prioritized. In the gym, interval training and circuits can be utilized to raise heart rate and improve metabolic conditioning. Rest periods should be minimized. Additionally, endomorphs should do cardiovascular exercise most days of the week and should at least take a long walk every day. Avoiding a sedentary lifestyle is critical. 
     
    Mesomorphs not only have the physique that most others aspire to, they also have an easier time with both eating and training. They carry more muscle and therefore have a higher metabolism too. They get great results with less work. They gain muscle mass rather easily and quickly. On the other hand, they don’t gain fat easily, despite eating high calorie diets. Mesomorphs need a high protein diet in the range of 1.2 to 1.6 grams per kilogram body weight per day, perhaps even higher in some cases. The balance can come from a variety of healthy carbs and fats. 
     
    Through sheer force of will, strict dieting and dedicated, focused training, some endomorphs and ectomorphs can take on the physical qualities or mesomorphs. It’s hard work — a lot harder than for mesomorphs themselves — but it can be done. Again, you need to train hard and often, and you need to focus on your diet, with a strong emphasis on your macronutrient composition, with a high percentage (25%-35%) of proteins.  
  • Stress Can Undermine Weight Loss and Increase Weight Gain

    Stress Can Undermine Weight Loss and Increase Weight Gain

    If you’re a stress eater (i.e., you eat to cope with stress), restricting calories can cause even more stress.

    If you eat a little less than your body needs, it can help you lose weight and body fat without sacrificing performance or wellbeing.

    However, eating a lot less, especially for a long time, and especially when you have major recovery needs—like hard athletic training or recovering from surgery—can actually thwart proper recovery. It can even cause your body to turn down the thermostat, restricting calorie burning. In essence, your body goes into preservation mode.

    Food is meant to nourish the body and the right amounts are vital to athletes. An excessive or chronic caloric deficit can impair performance, decrease lean muscle mass, and lead to a host of other issues ranging from hormonal imbalances to immune deficiencies.

    You need to eat enough to support your physiological needs. Unfortunately, most Americans (truly, the majority) eat well beyond their physiological needs. Stress is a common culprit.

    Cutting too many calories all at once can be very stressful and leave a person feeling like they’re starving. That’s not a formula for successful weight loss or athletic performance.

    It’s best to taper slowly, gradually reducing your caloric intake. Say, for example, that you (or your coach or nutritionist) determine that you should be eating 2,000 calories per day (I chose this because it’s a round number that’s easy to work with). Let’s also say that you discover, through the use of a food app, that you’re actually eating about 2,600 calories per day, which is why you’re overweight. 

    You’re best off tapering to 2,400 calories for about two weeks, and then dropping down 2,200 for another two weeks before finally settling in at your proper intake of 2,000 calories per day. This gradual step-down will keep your body from going into starvation mode and keep you from feeling hungry all the time, which will undermine your efforts. 
     
    Calorie requirements are highly individualized. An ideal daily intake of calories varies depending on age, metabolism and levels of physical activity, among other things. The Dietary Guidelines for Americans provide calorie estimates for men and women based on age and activity level. For example, these guidelines note that the general recommended intake for adult women ranges from 1,600 to 2,400 calories daily, while men often require 2,000 to 3,000 calories a day to maintain healthy body weights.  
     
     
     
    Sedentary people need fewer calories because sitting is not very demanding, and most Americans are quite sedentary. According to a study reported by the American College of Sports Medicine, American adults, ages 20 to 75, reported spending an average of 9.5 hours sedentary each day, and most of this time was accumulated at work and during leisure-time. Then factor in that most of us sleep 7-8 hours per night. 
     
    Harvard Medical School says that sedentary adults require 13 calories for each pound of their body weight on a daily basis. For example, a sedentary 130-pound woman needs about 1,700 calories, while a 175-pound, inactive man requires about 2,300 calories daily to maintain a healthy body weight.
     
    Yet, those numbers are to maintain body weight. If you need to lose weight, you’ll need to lower your caloric intake. The University of Washington suggests that overweight adults need 10 calories per pound of their desirable body weight to move toward that healthier weight. For example, an overweight woman with a goal weight of 130 pounds needs 1,300 calories daily, while an obese man trying to reach 175 pounds needs about 1,750 calories daily to reach his goal.
     
    Again, any caloric reduction should be done slowly and gradually. Give your body — particularly your stomach and brain, which communicate hunger signals — time to adapt. Initially, at least, focus on eating slowly and eating more whole foods, instead of just eating smaller portions. After a week or two of these adjustments, you can begin to focus on portion sizes and limiting caloric intake, which should accelerate your weight loss. Being hungry all the time will cause a backlash and result in bad food choices and, ultimately, overeating. 
     
    Highly-processed foods, aka “junk” foods, are typically loaded with sugar, fat, and sodium. Beyond that, they often harm the microbiome, the delicate balance of microorganisms in the gut, which contributes to various health problems. Highly-processed foods are also associated with increased systemic inflammation. 
     
    If you can gradually shift to to eating more whole, minimally-processed foods more often, you’ll be on the right track. Don’t do it all at once and don’t be militant about it. Slowly cut your calories to a number that suits your sex, age and activity level. 
     
    Don’t restrict food to the point that it causes anxiety or stress. That will prove to be unproductive and will undermine your goals. Simply put, don’t deprive yourself. By eating more slowly, and eating foods that are high in protein and fiber, which are more filling, you can become more attuned to hunger sensations and learn to stop before overeating. 
     
    Lastly find healthier ways to cope with stress that don’t involve eating, such as taking a walk, doing a crossword puzzle, talking to a close friend or loved one, or even meditating. Stress is part of life; don’t let it undermine you. 
     
    Be compassionate with yourself. Be on your own side and don’t be so judgmental. Good things — the fruits of your labor — take time to manifest. Keep moving forward and know that your sustained efforts will pay off. Be patient and remain focused. 
  • Sugar: The Biggest Dietary Threat to Your Health

    Sugar: The Biggest Dietary Threat to Your Health

    For decades, Americans were warned to reduce their fat and cholesterol intake in order to prevent heart disease, the nation’s No. 1 killer of both men and women. However, it is now known that sugar is the greater threat to our national health.
     
    The link between sugar and heart disease was purposefully obscured for decades. In 1964, after studies began linking sugar with heart disease, the Sugar Association (a sugar industry trade group) began funding research that cast doubt on sugar’s role in heart disease, in part by pointing the finger at fat.
     
    First, we should note the difference between naturally occurring sugar and added sugar, which is the real threat.
     
    Sugar occurs naturally in all foods that contain carbohydrates, such as fruits and vegetables, grains and dairy. Consuming whole foods that contain naturally occurring sugar is okay. Plant foods also have high amounts of fiber, essential vitamins, minerals and antioxidants, and dairy foods contain protein and calcium.
     
    Since your body digests these foods slowly, the sugar in them offers a steady supply of energy to your cells. A high intake of fruits, vegetables, and whole grains also has been shown to reduce the risk of chronic diseases, such as diabetes, heart disease, and some cancers.
     
    However, problems occur when you consume too much added sugar — that is, the sugar food manufacturers add to their products to increase flavor and/or extend shelf life. The added sugar in our food is generally regular table sugar (sucrose) and high-fructose corn syrup (a mix of fructose and glucose).
     
    Remarkably, sugar is the most popular ingredient added to foods in the US. In fact, about 80% of all sugar found in US foods has been added by the food industry. The top sources of sugar in the American diet are soft drinks, fruit drinks, flavored yogurts, cereals, cookies, cakes, candy, and other processed foods. 
     
    Yet, added sugar is also present in items you may not think of as sweetened, such as soups, cured meats, and ketchup. Yes, sugar isn’t merely found in sweets; it’s also added to many other processed foods, such as crackers, breads, peanut butter, and salad dressings. In fact, most processed foods contain sugar.
     
    While you might not think you’re eating much sugar, chances are you’re eating a lot more than you realize. Added sugar lurks in nearly 70% of packaged foods and is found in many sauces, snacks, most breakfast foods, and even many so-called ‘health foods’.
     
    The result: we consume way too much added sugar.
     
    Today, the average American consumes 66 pounds of added sugar each year, according to government data. That’s more than one pound of sugar each week!
     
    This is of great concern since too much added sugar is among the greatest threats to cardiovascular disease. Eating and drinking too many added sugars can also contribute to other health problems, such as type-2 diabetes and obesity. 
     
    “Sugar is actually more addictive than even cocaine, so it is probably the most consumed addictive substance around the world and it is wreaking havoc on our health,” says cardiovascular researcher James DiNicolantonio.
     
    Sugar’s impact on heart health has long been researched by Dr. Frank Hu, professor of nutrition at the Harvard T.H. Chan School of Public Health.
     
    In a study published in 2014 in JAMA Internal Medicine, Dr. Hu and his colleagues found an association between a high-sugar diet and a greater risk of dying from heart disease. Over the course of the 15-year study, people who got 17% to 21% of their calories from added sugar had a 38% higher risk of dying from cardiovascular disease compared with those who consumed 8% of their calories as added sugar.
     
    “Basically, the higher the intake of added sugar, the higher the risk for heart disease,” says Dr. Hu.
     
    High amounts of sugar overload the liver, potentially leading to fatty liver disease, a contributor to diabetes, which also raises your risk for heart disease.
     
    Consuming too much added sugar can also raise blood pressure and increase chronic inflammation, both of which are pathological pathways to heart disease.
     
    “The effects of added sugar intake — higher blood pressure, inflammation, weight gain, diabetes, and fatty liver disease — are all linked to an increased risk for heart attack and stroke,” says Dr. Hu.
     
    Diabetes has reached epidemic proportions in the US. It kills more Americans each year than AIDS and breast cancer combined, according to the American Diabetes Association.
     
    More than 100 million US adults are now living with diabetes or pre-diabetes, according to a 2017 CDC report. Pre-diabetes is a condition that, if not treated, often leads to type-2 diabetes within five years. Despite the fact that more than a third of US adults have pre-diabetes, the majority don’t know it, says the CDC.
     
    Even a relatively small amount of sugar can do a lot of damage to your health. People who add 150 calories of sugar to their daily diet — from sources such as a 12-ounce can of Coke or an ounce of M&Ms — have 10 times greater risk of developing diabetes.
     
    Additionally, people who consume a diet high in fructose risk damaging their immune systems, a new study suggests. The study shows that fructose, which is commonly found in sugary drinks, sweets and processed foods, causes the immune system to become inflamed.
     
    Furthermore, researchers say that consuming too much added sugar (as well as artificial sweetener, fast foods, fried foods, processed foods, and alcohol) can harm your gut microbiome.
     
    The American Heart Association (AHA) has long suggested that men consume no more than nine teaspoons (36 grams) of added sugar per day. That’s close to the amount in a 12-ounce can of soda. Women are advised to limit added sugars to no more than six teaspoons a day (24 grams).
     
    However, the average American still eats about 17 teaspoons (19 for men, 15 for women) of added sugar a day, according to the CDC. That’s about double the recommended limit for men (nine teaspoons) and two-and-a-half times the limit for women (six teaspoons). This doesn’t include the sugars that occur naturally in foods like fruit or dairy products.
     
    In other words, American adults consume an average of 77 grams of added sugar per day. Again, that’s more than two times the recommended amount for men and two-and-a-half times the recommended amount for women. 
     
    Recognizing the problem, the AHA now recommends that sugar intake be limited to less than 6% of daily calories, and the Dietary Guidelines Advisory Committee agrees.
     
    Yet, roughly 90% of Americans still get more than 10% of daily calories from sugar, and the top 10% of sugar-consumers ingest a whopping 40% of their calories from sugar!
     
    Beverages are the leading source of added sugars, accounting for 47% of the total. Examples of sugary beverages include regular soda, fruit drinks, sports drinks, energy drinks, sweetened waters, and coffee and tea beverages with added sugars.
     
    The US ranks third in the world in sales of sugary drinks. In 2013, the average American drank just over 38 gallons of soda a year — or about eight 12-ounce cans a week. 
     
    Reading food labels is one of the best ways to monitor your intake of added sugar. Total sugar, which includes added sugar, is often listed in grams. Note the number of grams of sugar per serving as well as the total number of servings. The package might only say 5 grams of sugar per serving, but if the normal amount is three or four servings, you can easily consume 20 grams of sugar. That’s a lot of added sugar.
     
    By simply being more aware, you can substantially reduce the amount of added sugar in your diet. It would certainly be worth your while.
  • Big-Boned, Big Myth

    Big-Boned, Big Myth

     

    You may have heard the term “big-boned” used to describe some overweight or obese people. Sometimes it’s a self-description. How much do our bones really contribute to our weight?
     
    The average human skeleton will account for around 12%-15% of total body weight. So, a 200-pound man would have a skeletal weight of 24-30 pounds. A 150-pound woman has a skeletal weight of 18-22.5 pounds. Bone density refers to the concentration of minerals in your bones, yet dense bones may add only a few pounds to your frame. As an adult continually gains weight throughout life, it’s not because their bones become continually bigger and heavier.
     
    An adult’s skeleton weighs more than a child’s. And a 7-foot person’s skeleton weighs more than a 6-foot person’s, who’s skeleton weighs more than a 5-foot person’s skeleton. Beyond this, people are not “big-boned.” The bones in people of the same height are relatively the same weight. Most people who weigh too much for their height typically do so because of excess body fat, though a more-muscular body does indeed weigh more than a less-muscular body.
     
    Seventy-five percent of Americans are now either overweight or obese. Yet, most people aren’t body builders. Our national weight problem is a fat problem, unrelated to too much muscle or too much bone.
     
    The term “big-boned” is not a medical term. One orthopedic surgeon would tell her patients, “I have seen your bones, and they’re not big.” Being “big-boned” or “small-boned” doesn’t justify a 30-35 pounds differential from a normal-weight person of your height. If you are truly convinced that you are just big-boned and not overweight, buy a body-fat scale to measure your fat percentage. Excess weight is either the result of excess fat or excess muscle, not excess bone or big bones.
     
    So, the notion of being big-boned is a big myth… unless you’re Shaquille O’Neal, who is 7-feet, 2-inches tall.
     
    By the way, in 1992, at the start of O’Neal’s rookie season, he was listed at 325 pounds. According to Shaq, he weighed 395 pounds by 2002. But it wasn’t because his bones got bigger or heavier though.
  • Diet vs Nutrition

    Diet vs Nutrition

    While many people continually “go on a diet” (and then another and another), everyone has a diet. I’ve never gone on a diet, but I’ve always had a diet. As I always say, diet should be viewed as a noun, not a verb. It’s a thing you have, not an action you take. Every action has a reaction (intended or otherwise), so any diet plan you initiate can quickly be halted in favor of something else.
     
    If you instead think of your diet as part of your lifestyle, you’re much more likely to stick to it. 
     
    Everyone has a diet, but not everyone gets good nutrition. In the minds of many people, low-calorie means healthy. Yet, this isn’t necessarily true.
     
    For example, a rice cake has just 35 calories. Yet, it is almost entirely devoid of fiber and protein. Though a rice cake has very few calories, it also has very little nutrition, not to mention that it’s entirely processed.
     
    On the other hand, an avocado, which grows on a tree, is both calorically and nutritionally dense. An avocado can weigh anywhere from 8 ounces to 3 pounds (48 ounces). So, serving size matters.
     
    One cup (8oz) of sliced avocado has 234 calories and 21 grams of fat, most of which is monounsaturated. It is packed with fiber (10g) and potassium (more than a banana), and is also a great source of vitamin-C, folate and B-6. Additionally, it has virtually no sugar (despite being a fruit) and very few carbs (for those who care about such things).
     
    In short, an avocado is loaded with healthy fats, fiber and various important nutrients.
     
    Yet, some people would choose a nutritionally lacking rice cake over an avocado simply because it is lower in calories. Bad move. Caloric content and nutritional content are not necessarily related. 
     
    No one thinks of a Big Mac as health food. Yet, you could eat three Big Macs a day and still lose weight. Don’t believe me? Well, a Big Mac has just 550 calories. Eat three a day and you’d ingest just 1,650 calories. Since the average American now eats a whopping 3,660 calories per day, eating one Big Mac for breakfast, lunch and dinner would cut that average intake by more than half. Do that, and watch the pounds melt away!
     
    However, you’d be missing lots of important nutrition on the Big Mac Diet. McDonald’s signature sandwich has minimal calcium, potassium and fiber, and zero vitamin D. However, it is loaded with sodium (44% of the daily value) and has 11 grams of saturated fat (53% of the daily value). Eat three a day and you’d be ingesting an enormous amount of salt and unhealthy fat.
     
    Oh, and one Big Mac also has nine grams of sugar. Eat three of them and you’d intake 27 grams of sugar, which is above the 24-gram daily limit recommended for women by the American Heart Association.
     
    Yet, on this Big Mac Diet you’d lose weight, and that would ultimately have a positive effect on your health. Scientific evidence shows that losing just 10 pounds can decrease hypertension, improve good cholesterol (HDL), lower triglycerides, decrease insulin resistance, reduce inflammation in blood vessels, improve or reverse sleep apnea, and increase energy and vitality.
     
    That said, there are better, healthier ways to lose weight than the Big Mac Diet. 
     
    The point is that calories and nutrition are not synonymous. You can eat a low-calorie diet that is not healthy. More to the point, you can eat a low-calorie diet and not necessarily be healthy.
     
    On the other hand, you can eat a very healthy diet featuring high-calorie foods that are packed with nutrition (i.e., avocados, nuts, nut-butters, salmon, whole-fat yogurt, etc.). Additionally, high-calorie foods are more filling than most low-calorie foods (like rice cakes), meaning you might ultimately eat less.
     
    Low calorie foods are not necessarily nutritious, beneficial or preferable. And high-calorie foods are not necessarily unhealthy or to be avoided. The goal should be to maximize nutrition at each and every meal, even if you also seek to limit calories.
     
    If you need to lose weight to be more healthy, you can do this by eating healthy, whole foods, such as fruits, vegetables, a wide variety of animal- and/or plant-based proteins, plus whole grains (There’s more than just wheat, people! Try spelt, millet, amaranth, quinoa, black or red rice, whole oats, etc.).
     
    And, yes, you can indeed lose weight by including healthy, high-calorie foods in your diet. You just need to limit your total caloric intake. To do that, you need to track your daily caloric input. And you should also know how many calories you need each day.
     
    As the Twinkie Diet proved, you can eat an unhealthy diet and still lose weight. The Big Mac Diet would be no different.
     
    By the same token, you can have a healthy diet and still gain weight, if your caloric intake is higher than your needs.
     
    To lose weight, it comes down to quality and quantity. You should aim for higher quality foods, and a lower quantity of them, each day.
  • Good Habits Can Have a Domino Effect

    Good Habits Can Have a Domino Effect

    We all have various reasons that we work out, assuming we do so at all. For some, it’s to relieve stress and anxiety. Some may feel a great sense of pride and accomplishment afterwards. For others, working out may be a vanity project that provides a sense of confidence and the ability to fit into tight jeans or proudly wear a tank top or a backless dress.
     
    Yet, health outcomes, not simply appearance, should be your main motivation. It’s well established that the health benefits of exercise go beyond the physical. Once you make exercise part of your routine, you may notice a host of psychological benefits, such as feeling more energized, less stressed, and sleeping better.
     
    As you begin to notice how much better exercise makes you feel, the more you’ll want to do it regularly. At that point, exercise becomes a habit. What’s most important is to perform the activities you really enjoy, which will help you adhere to your program.
     
    It’s said that old habits are hard to break and new habits are hard to form. This is especially true with exercise. If you’re not in the habit of exercising, remaining physically inactive is effortless. To create the habit of exercising, however, takes a lot of resolve, determination and effort.
     
    The more consistent an action is, the more likely it is to become a habit. This means that exercising every day is more likely to result in habit formation. One useful idea is to schedule your exercise for a given time each day, as you would with a personal trainer. Accountability is critical to maintaining your schedule and forming a habit.
     
    As Charles Duhigg, author of The Power of Habit notes, “When people start habitually exercising, even just once per week, they start changing other, unrelated patterns in their lives, often unknowingly. They often start eating better, becoming more productive, smoking less and feeling less stressed. It’s not completely clear why. But, for many people, exercise is a keystone habit that triggers widespread, positive change.”
     
    Researchers asked some study participants to write down what they ate once a week. This keystone habit, food journaling, created a structure that helped other habits to flourish. Six months into the study, these participants had lost twice as much weight as the other study participants.
     
    Unfortunately, 42 percent of Americans are obese, according to the CDC, and another 30 percent or so qualify as overweight. So, roughly three-quarters of our population has an unhealthy bodyweight. Because of this, many people view exercise solely as a means of weight loss. But there’s a whole lot more to it than that. The mental and emotional components of exercise cannot be emphasized enough.
     
    Exercise has been shown to increase grey matter in the brain, according to research published by the Mayo Clinic. Exercise also promotes brain plasticity by stimulating the growth of new connections between cells. Consequently, exercise improves cognitive ability and memory. 
     
    Furthermore, exercise releases chemicals, such as endorphins and serotonin, that improve your mood. As noted, exercise not only enhances self-esteem, it also reduces anxiety and depressed mood.
     
    “There’s good epidemiological data to suggest that active people are less depressed than inactive people. And people who were active and stopped tend to be more depressed than those who maintain or initiate an exercise program,” says James Blumenthal, PhD, a clinical psychologist at Duke University.
     
    Yet, there’s no denying the impact that exercise can have on our physical health and our ability to function well, aka, perform our activities of daily living.
     
    Don’t wait until your doctor tells you to exercise! At that point, too much time will have been lost.
     
    More than 1-in-3 adults, about 92.1 million people, have at least one type of cardiovascular disease, which is preventable.
     
    In fact, many forms of chronic illness are preventable. According to the CDC, the health-risk behaviors we can change include: lack of exercise/physical activity, poor nutrition, tobacco use and excessive alcohol use. These four behaviors cause much of the illness, suffering and early death related to chronic diseases and conditions. In essence, they are bad habits that can be corrected.
     
    It’s important to remember that health is not just about food and exercise. Everyone would benefit from things such as meditation, learning a new skill, developing a new hobby, and/or growing your social network. Each of these things can make you a healthier person in measurable ways. 
     
    If you’re new to exercise or haven’t done it in a long time, start slowly. Don’t take the attitude that you can get fit today or even this week. Allow your body time to adjust to the demands you’re placing on it. Your exercise routine should be progressive, growing in either intensity or duration as your fitness level gradually improves.
     
    The physical effects of exercise — such as weight loss, lower blood pressure or a lower resting heart rate — take time and patience; you may not see your numbers move for weeks to months.
     
    The mood boost from exercise, however, is often immediate, offering near-instant gratification. Alleviating mood disorders, such as anxiety or depression, may take longer, but the mental and emotional effects of exercise are often immediately tangible.
     
    The most important takeaway is that good habits can have a domino effect, with one healthy change leading to another and so on. After committing to a few healthy acts, we’re less likely to back-step and commit unhealthy acts. After all, no one wants to undermine their own progress.
     
    Start with the easiest change you can think of; pick the low hanging fruit first. Once you’ve created a healthy daily habit that lasts a couple of weeks, add another easy-to-achieve step. View these changes as rungs on a ladder; take them one step at a time. Be consistent and be progressive. But don’t take on too much, too soon. 
     
    Small victories lead to a sense of pride, achievement and accomplishment. These are all empowering and rewarding feelings. Ultimately, one good change will lead to another.
  • How Your BMR and RMR Contribute to Your Weight Status

    How Your BMR and RMR Contribute to Your Weight Status

    If you’ve ever weighed yourself before bed at night and again in the morning, you may have been surprised that you lost anywhere from 1-3 pounds. This is fairly normal. We all lose weight at night while sleeping.
     
    How much we lose overnight depends on whether we get enough sleep, how much water we excrete, and our basal metabolic rate (BMR), which is largely determined by the amount of muscle we have (muscle is quite metabolically active).
     
    The body is in an entirely aerobic state while we’re sleeping, since it uses only fat to operate in such a low-energy state (carbohydrates are used only for higher energy demands). Our heart, brain and other organs all need energy to maintain basic functions while we’re sleeping.
     
    In one hour of sleep, most people burn 0.4 to 0.5 calorie for every pound of body weight. For example, a 150-pound person would multiply 150 by 0.4 or 0.5 to get 60 to 75 calories used in one hour of sleep. After eight hours of sleep, that person has burned 480 to 500 calories.
     
    A 200-pound person would burn 80-100 calories per hour, or 640-800 calories during eight hours of sleep.
     
    This may seem unbelievable, but it’s true. You’re burning calories all day long — even while sleeping — just to stay alive; that’s your BMR. Additionally, energy is also expended by digesting your food and from non-exercise daily movements, such as brushing your teeth, getting dressed and pouring your morning coffee. This additional expenditure is known as your resting metabolic rate (RMR).
     
    For American women, the average BMR is 1,493 calories. For American men, the average BMR is 1,662 calories.
     
    Your BMR accounts for about 70 percent of the calories you burn every day (in general, men have a higher BMR than women). This is critically important since there is no way we can exercise away all the calories we consume each day.
     
    Muscle is the single most important predictor of how well you metabolize your food, burn calories, and burn body fat. However, beginning in our late 20s, we start losing muscle, which means our metabolism also starts declining. A consistent weight training program can stop this decline and even reverse it.
     
    There are approximately 3,500 calories in a pound of stored body fat. If you subtract 3,500 calories each week through diet, exercise or a combination of both, you will lose one pound of body weight.
     
    On average, 75 percent of this is fat and 25 percent is lean tissue, which is why it’s so important to strength train while attempting to lose weight; you don’t want to lose your precious muscle along with that unwanted fat. Muscles at rest burn three times more calories than fat, so maintaining or increasing muscle mass influences BMR.
     
    In simple terms, if you’re seeking to lose weight, aim for a 500-calorie deficit each day of the week (7 x 500 = 3,500).
     
    As a guide, the American College of Sports Medicine (ACSM) recommends that women never drop their calorie-intake level below 1,200 per day and men should not go below 1,800 calories per day.
     
    So, back to where we started: it’s possible for a 150-pound person to lose about 1 pound each week simply by sleeping eight hours every night. Remember, a person of this weight burns roughly 500 calories while sleeping each night. Sleep is very valuable!  In fact, sleep deprivation has been linked to an increase in weight.
     
    Clearly, much of this 1-pound of weight loss is water, not just fat (we lose water gradually each night through respiration and perspiration), but burning 500 calories overnight while sleeping is no small matter.
     
    The average person eliminates about 1.2 liters of water in urine each day, and also eliminates about 1 liter a day through perspiration and respiration. That’s 2.2 kilograms (almost 5 pounds) of weight fluctuation happening throughout the day.
     
    So, don’t get caught up in the daily fluctuations of your body weight. You can gain up to 5 pounds during the day just from your food and beverage intake — but it’s not all fat!
     
    Your BMR, non-exercise daily movements, and your daily exercise routine should allow you to at least maintain your present weight. To lose weight, however, you’ll have to reduce your daily caloric intake.
     
    You weigh less in the morning than during the rest of the day because you don’t (normally, at least) eat and drink during the night. Remember that two cups of water (16 ounces or one pint) weighs one pound, so drinking a tall glass of water will temporarily be reflected in your weight.
     
    The most accurate time to weigh yourself is first thing in the morning, when you have an empty stomach. Weighing yourself while naked will also give you a more accurate reflection of your weight. 
     
    Lastly, always weigh yourself on the same scale. Even if it’s off by a pound or so, it will be relative to itself and still reveal any upward or downward movements. Different scales may give you different results, which can be misleading or even maddening.
  • The Benefits of Intermittent Fasting

    The Benefits of Intermittent Fasting

    A lack of sleep may be a big contributor to America’s considerable weight problem.
     
    The National Sleep Foundation (NSF) recommends 7-9 hours of sleep each night for adults, ages 18-64. Yet, more than a third of American adults are not getting enough sleep on a regular basis, according to a CDC study.
     
    Sleeping less than seven hours per day is associated with an increased risk of developing chronic conditions such as obesity, diabetes, high blood pressure, heart disease, stroke and frequent mental distress, according to the CDC.
     
    The hunger hormones leptin and ghrelin have gotten a lot of attention in recent years. Though you may have heard of them, you may not be familiar with their functions.
     
    Think of the ‘l’ in leptin standing for lose. Leptin suppresses appetite and therefore contributes to weight loss. Think of the ‘g’ in ghrelin standing for gain. Ghrelin is a fast-acting hormone that increases hunger and leads to weight gain.
     
    When you’re sleep deprived, research shows, ghrelin levels surge while leptin plummets. The result is an increase in hunger.
     
    The key to reducing your nighttime cravings is to get more sleep; 7-9 hours.
     
    Another key to successful weight loss technique is intermittent fasting or time-restricted eating.
     
    Recent research shows the benefits of intermittent fasting, and those who have tried it often view it as a sustainable, long-term solution.
     
    In the simplest form, intermittent fasting would amount to 12 hours on and 12 hours off. For example, food can be eaten only between 7am and 7pm or 8am and 8pm.
     
    However, research shows that the sweet spot seems to be 10 hours on and 14 hours off. For example, eating only from 9am to 7pm, and then fasting until 9am the next day.
     
    Some intermittent-fasting proponents use only an eight-hour feeding window, with 16 hours of continual fasting each day. For example, eating meals between 12pm and 8pm each day, and fasting at all other times.
     
    This helps to thwart any late-night snacking habits.
     
    The benefit of time-restricted eating is that it allows you to naturally reduce your food intake without counting calories. That’s preferable to most people.
     
    Ultimately, intermittent fasting is about the “when” of eating, not the “what” or “how much.”
     
    Some researchers believe that the rise of later nighttime eating may have thrown off our evolutionary circadian rhythm, the 24-hour cycle that governs the physiological processes of humans and most other living beings, which may be contributing significantly to increases in obesity.
     
    Some studies suggest that by honoring the circadian rhythm and restricting feeding primarily to the daylight hours, we can improve our health and prevent disease.
     
    Fasting allows us to eat in harmony with our circadian rhythm. Circadian rhythms — which determine the sleeping and feeding patterns of all animals, including humans — can be modulated by external cues, such as sunlight.
     
    However, living in the 21st Century has disrupted our circadian rhythms. There is so much artificial light at night that the mind can confuse it with daytime. We also spend an exceptional amount of time (up to 12 hours a day) in front of screens (TVs, computers, tablets and smart phones) that emit blue light, which stimulates the retinal nerves and brain.
     
    21st Century adults spend, on average, 87%-93% of our 24-hours indoors and less than 5% of hours outdoors during the day. This light-dark rhythm disruption leads to less daytime alertness, and promotes depression (especially in older adults) and ADHD.
     
    This has resulted in circadian misalignment, in which our central and peripheral clocks are out of synch. Examples: too much light at night, sleep during daytime and food intake at night.
     
    Time-restricted feeding (12-16 hours of non-feeding) has proven to be the best match to our circadian clocks. The key is to eliminating nocturnal eating. The health benefits of time-restricted feeding double every extra hour of non-feeding time beyond 12 hours, up to 16 hours.
     
    While it is certainly wise to eat a variety of whole foods with high-quality sources of protein, fat and carbohydrate, timing may be the most crucial element when it comes to our eating habits.
     
    Another key is mindfulness. Being a more conscious (mindful) eater also helps you make healthier decisions during your eating window each day, so that you have adequate protein, fiber and water in your diet.
     
    In one study (by Dr. Satchidananda Panda, PhD), participants who adjusted their feeding time from their typical 14–15 hours down to 10 hours not only shed an average of 4% of their body weight, but also reported significantly improved energy levels and more satisfying sleep. Most remarkably, they ate their normal foods and didn’t change their exercise habits.
     
    Choosing to commit to intermittent fasting is easier if you do it with your partner/spouse or family. Any lifestyle change made in conjuncture with someone you live with can make a big difference. It creates a support system and can help keep you accountable.
     
    At the least, focus on getting 7-9 hours of sleep each night and eliminate nighttime snacking. However, you may want to try intermittent fasting / time-restricted eating for about a month to see how it works for you.
     
    It’s not very challenging. I do it and it’s made a difference for me. In fact, I highly recommend it.
