Over the past decade, interest in anti-aging treatments and interventions aimed at promoting health, vitality and youthfulness over the life course into old age, has risen exponentially. The popularity and rise of anti-aging interventions has been fueled by the aging baby-boomer generation and the great dissatisfaction surrounding the current medical system in the US and many other Western nations.
Are you frustrated with today’s big-pharma dictated assembly line medicine with doctors who only spend 7 minutes per visit with their patients? Are you against the routine “have a symptom – take a pill” medical system mantra that is so pervasive in modern medicine? Then anti-aging medicine, a medical specialty developed and led by The American Academy of Anti-Aging Medicine (A4M) is for you.
The current medical system – background to the status quo

An editorial from the journal Clinical Interventions In Aging eloquently outlines the emergence of the current medical system status quo 1:
“Prior to the discovery of penicillin and production of antibiotics, extrinsic disease was the greatest threat to achieving maximum life potential (longevity). That single event increased life-span several decades for the majority of people living in first world nations. However, protection against lethal infection provided by antibiotics exposed older humans to a wide variety of life-threatening diseases resulting from disintegration of internal order during senescence. These intrinsic diseases including diabetes, stroke, heart attack, cancer, and a multitude of others, resulted in creation of medical
subspecialties. Although each specialty focused upon different organs and systems, they all administered treatment in response to disease. In other words, the operative model for modern medicine which deals with intrinsic disease is the same as that which was used for extrinsic disease, i.e., a disease occurs and then it is treated.
However, unlike therapy for infection which generally cures disease, treatment of intrinsic diseases only provides symptomatic relief, rarely affecting the underlying causes. Also, because it targets specific symptoms, this approach treats the disease condition as an isolated entity, independent of other bodily functions. Thus, the cardiologist, neurologist, allergist, and dermatologist focus their attentions only upon problems occurring within the system(s) limited by their training. Accordingly, they prescribe drugs that were created to specifically suppress or relieve symptoms directly related to the problem(s).
Despite the fact that this approach rarely provides a cure, it is effective in extending life, if not necessarily its quality, because many of the symptoms of intrinsic disease such as extremely high blood pressure, severe hyperglycemia, or profound breathing difficulties can lead to fatal complications.
The pharmaceutical industry fits well within the disease model for medical practice. This is because advances in cellular biology and biochemistry allow medicinal chemists to design compounds capable of modulating receptor, enzyme, and other molecular functions that block or attenuate the symptoms of underlying disease. Generally these effects are accompanied by secondary and unintended metabolic consequences. However, if the net result of administering the compound is to relieve primary symptoms
then a simple and measurable indicator of efficacy has been achieved and a new drug is born. In other words, the pharmaceutical industry embraces the disease-oriented approach to medical practice because it provides a simple and unambiguous measure of efficacy for their products.
With continuing research into the consequences of aging, it is becoming apparent that medical practice must evolve from this disease-oriented model to one that is health-directed so as to ensure quality of life with longevity. In this alternative approach, patient health and vitality is prolonged and onset of intrinsic disease(s) is delayed or even prevented well into old age.
Although this approach is currently being employed by practitioners around the world, it is widely opposed by many in the traditional medical community and especially by the pharmaceutical industry. One reason for this reluctance is that a health-directed approach to medicine blurs the line between specialties since it requires consideration of the entire body and its interrelated functions, rather than single systems in isolation. This requirement tends to diminish a specialist’s expertise and thus is unacceptable to some. As a result, it is not surprising that medical practitioners who are committed to their individual specialty are not willing to accept change.
Another reason is that effective interventions that delay or prevent consequences of aging are not as easily demonstrated, because rather than simply reducing the intensity of preexisting symptoms (as is required in the disease-oriented treatments), proof for health-oriented interventions requires that efficacy be demonstrated by the absence or delay in onset of symptoms. This type of proof requires advanced and sensitive measurement technologies and need long-term studies.”
Thus, current medicine is effective in preventing death from age-related diseases without curing the diseases or delaying their onset. While preventing deaths, this disease-oriented medical approach increases in the number of people with age-related diseases. In addition, each disease of aging is now treated separately, which is costly and can lead to unintended and unavoidable adverse effects. For example, chemotherapy, used for cancer treatment, has a negative impact on normal tissues and organs. And insulin, which is used for diabetes, has pro-aging effects 2 and may accelerate some pathologies, such as cancer 3, 4.
Proof that the current disease-oriented medical system isn’t working
Recent reports show that the disease oriented traditional medical approach isn’t helping us:
* Cardiovascular diseases (CVD) remain the leading cause of morbidity and mortality in modern societies, followed by cancer 7, 8. In 2009, cardiovascular diseases accounted for 32.3% of all deaths, or 1 of every 3 deaths in the United States 8.
* In 2009, 34% of deaths attributable to cardiovascular diseases occurred before the age of 75 years, which is well before the average current life expectancy of 78.5 years 8.
* In 2005, 133 million Americans had at least one chronic illness 9.
* Overweight/Obesity has become a major health concern. Among Americans age 20 and older, 154.7 million are overweight or obese 8. The current US population is 316.7 million 10; thus close to 49%, or almost 1 out of every 2 adults, are overweight or obese.
* In 2010, more than one third of children and adolescents were overweight or obese 11.
* Obesity is associated with 20% higher all-cause mortality in adults 12, and between 1990 and 2010, DALY (disability-adjusted life-years, which is the sum of years of life lost due to premature mortality and years lived with disability) related to elevated BMI, independent of diet composition, increased by 45% 13. If past obesity trends continue unchecked, the negative effects on the health of the U.S. population will increasingly outweigh the positive effects gained from declining smoking rates. Failure to address continued increases in obesity could result in an erosion of the pattern of steady gains in health observed since early in the 20th century 14.
* Obesity in childhood and adolescence often tracks into adulthood, and elevates obesity-induced health risks later in life. For type-2 diabetes, obese adults who were also overweight or obese in childhood and adolescence have 12.6 higher odds, than for those who were obese in adulthood only 15. A similar trend is seen for cardiovascular risk in later life 15, 16.
* High blood pressure is a major and most common risk factor for developing cardiovascular disease and mortality 17. The mortality risk doubles for every 20-mmHg increase in systolic blood pressure above the threshold of 115mmHg and for every 10-mmHg increase above the diastolic blood pressure threshold of 75mmHg 18.
* In 2010, an estimated 19.7 million Americans had diagnosed diabetes, representing 8.3% of the adult population. An additional 8.2 million had undiagnosed diabetes, and 38.2% had pre-diabetes, with elevated fasting glucose levels 8. The prevalence of diabetes is increasing dramatically, in parallel with the increases in prevalence of overweight and obesity.
* On the basis of NHANES 2003–2006 data, the age-adjusted prevalence of metabolic syndrome, a cluster of major cardiovascular risk factors related to overweight/obesity and insulin resistance, is approximately 34% (35.1% among men and 32.6% among women) 8.
* The United States spends significantly more on health care than any other nation. In 2006, our health care expenditure was over $7,000 per person 19, more than twice the average of 29 other developed countries 20. We also have one of the fastest growth rates in health spending, tripling our expenditures since 1990 19. Yet the average life expectancy in the United States is far below many other nations that spend less on health care each year.
* An increasing percentage of health care dollars spent in the U.S. are spent on people with chronic conditions. In 2004, the care given to people with chronic conditions accounted for 85 % of all of health care spending 21.
* In 2000, the annual direct cost of physical inactivity in the USA was estimated as $76.6 billion 22.
* The total number of inpatient cardiovascular operations and procedures increased 28% between 2000 and 2010 8.
* The total direct and indirect cost of CVD and stroke in the United States for 2009 was $312.6 billion. By comparison, in 2008, the estimated cost of all cancer and benign neoplasms was $228 billion. CVD costs more than any other diagnostic group 8.
* In treating patients with chronic conditions, 66% of physicians believe their training did not adequately prepare them to educate patients with chronic conditions, and provide effective nutritional guidance 23.
* The largest number of people with chronic conditions is of working age and is privately insured: 78 million people with chronic conditions have private insurance coverage and their care accounts for about 73 % of private insurance spending. Almost all Medicare dollars and about 80% of Medicaid spending is for people with chronic conditions 21.
What are the causes behind the surge of chronic age-related diseases?
The risk factors for these chronic diseases are mainly caused by unhealthy lifestyles 24. Four modifiable health risk behaviors – lack of physical activity, poor nutrition, tobacco use, and excessive alcohol consumption – are responsible for much of the illness, suffering, and early death related to chronic diseases. Due to the importance of physical inactivity for morbidity and mortality, it has recently been suggested that physical inactivity per se should be regarded as a disease 25.
Stats related to unhealthy lifestyles:
* People consistently overestimate their own health behavior; almost 90% rate themselves as healthy. The reality is that 9 out of 10 have at least one risk factor for heart disease and stroke 26.
* Among young adults aged 18-39 years, only 20% meet low risk criteria, and almost 60% have high levels of at least one risk factor 27. In young adult and middle-aged populations, aged 18 to 59 years, only 5-10% have a low health risk status 28.
* Risk factor measurements in children, obtained at or after 9 years of age, are predictive of sub-clinical atherosclerosis and cardiovascular disease risk in adulthood 29. As children are not screened for health risks to the same extent as adults, this might contribute to an increased disease burden in the coming decades when today’s kids are grownups.
* Today very few Americans are at low risk for heart disease. Approximately 78% of adults aged 20-80 years alive today in the United States are candidates for at least one prevention activity 30. Over 55% of young adults have at least one cardiovascular disease risk factor, and over 37% reported having two or more 31.
* If everyone received the prevention activities for which they are eligible, heart attacks and strokes would be reduced by 63% and 31%, respectively 30. Of the specific prevention activities, the greatest benefits to the US population come from controlling pre-diabetes, weight reduction in obese individuals, lowering blood pressure, and improving blood lipids 30.
* Lack of regular exercise has been estimated to account for 23% of U.S. deaths, with these deaths being attributable to nine chronic diseases 32.
* Poor diet and physical inactivity were the second leading cause of preventable deaths from 1980–2002 33.
* Data very strongly support an inverse association between lifetime physical activity and all-cause mortality, with lifetime inactive individuals having over 30% higher risk of dying compared with lifetime active individuals 34.
* Majority of adults (81.6%) and adolescents (81.8%) do not get the recommended amount of physical activity (150 min/week) 35, and 23% report no leisure-time physical activity at all in the preceding month 36.
*32 percent of U.S. adults engage in no aerobic leisure-time physical activity 8.
* Objective evaluations show that U.S. adults an average only achieve 45 minutes/week (6 min/day) of moderate physical activity and only 18 minutes/week (2.5 min/day) of vigorous physical activity 39.
* With regard to vigorous physical activity, 28% of men and 16% of women achieve 75 min/week and 13% and 7.0% achieve 20 min/day on 3 days/week 40.
*A recent study shows that among people who do meet the physical activity guidelines, only 34.9% of men and 21.6% of women attain an average physical activity level (PAL) of 1.75, the threshold for preventing weight gain 40. To increase overall physical activity levels, a high level of physical activity throughout the day would be required for most people. This explains why individuals who accumulate 30 min/day of moderate-to-vigorous physical activity but are otherwise sedentary during the day, may meet the guidelines for cardiovascular health, without achieving the minimum levels to avoid excessive weight gain 40.
* A low intake of fish oil/fatty fish (less than 62 mg/day of EPA and DHA) compared to a higher intake of over 250 62 mg/day of EPA and DHA, more than doubles the risk for heart disease 43.
* Data from the National Health and Nutrition Examination Survey (NHANES) indicate that between 1971 and 2004, average total energy consumption among US adults increased by 22% in women (from 1542 to 1886 kcal/d) and by 10% in men (from 2450 to 2693 kcal/d) 8.
* The increases in calories consumed are attributable primarily to greater carbohydrate intake, in particular, of starches, refined grains, and sugars. Other specific changes related to increased caloric intake in the United States include larger portion sizes, greater food quantity and calories per meal, and increased consumption of sugar-sweetened beverages, snacks, commercially prepared (especially fast food) meals and calorie dense foods 8.
Impact of improved lifestyle habits
The importance of lifestyles for health promotion and anti-aging is underscored by the fact that although genetic factors and age (which are non-modifiable risk factors) are important in determining cardiovascular disease, modifiable risk factors are the major contributors to cardiovascular morbidity and mortality, and account for 90% of all heart attacks 44-47.
Examples of modifiable risk factors that have major consequences for health and determine how gracefully an individual will age, are abdominal obesity, abnormal blood lipoprotein profiles, diabetes, unhealthy food habits, and lack of regular physical activity.
Because a sedentary lifestyle accelerates the aging process 48-52, regular physical activity/exercise is a cornerstone in the anti-aging arsenal:
* 1 vigorous workout per week has been shown to be associated with a 39% reduction in mortality for men and 51% reduction in mortality for women 53.
* Moderate-intensity exercise for 15 min a day can reduce all-cause and all-cancer mortality and extended an individual’s lifespan for an average of 3 years 54. This minimum amount of exercise was found to be applicable to men and women of all ages, even those with cardiovascular diseases or lifestyle risks.
* For each minute increase in treadmill time on a maximal exercise test made 5 years apart, there was a corresponding 8% decrease in risk of mortality, regardless of baseline health status 55.
* Regular exercise and physical activity is associated with a reduced risk by as much as 60% of developing many common diseases, such as the metabolic syndrome, diabetes, cardiovascular diseases, breast cancer, colon cancer, prostate cancer, pancreatic cancer, high blood pressure, osteoporosis, Alzheimer’s, asthma and arthritis 56, 57.
* Regular vigorous exercising can postpone disability by 16 years 58.
* Minimal adherence to current physical activity guidelines, which yield an energy expenditure of about 1000 cal per week, is associated with an up to 30% reduction in risk of all-cause mortality 61. Further reductions in risk are observed at higher volumes of physical activity related energy expenditure 61.
* Reducing sitting time to 3 h/day or less is estimated to increase life expectancy in the US population by 2 years 62. Today, people in the US on average spend about 8 hours daily, i.e. half of their waking time, being sedentary 63.
* Among older adults, compared to those who were sedentary for 4 hours/day or more, those who were moderately (2–4 hours/day) and least sedentary (less than 2 hours/day) were 38% and 43% more likely to age successfully, respectively. Among middle-aged adults, those who were least sedentary were also 43% more likely to age successfully 64.
Food habits and nutrition is the other major lifestyle factor that can confer substantial health benefits and help stave off many chronic diseases 65-68:
* A non-calorie restricted Mediterranean diet supplemented with extra-virgin olive oil (33 fl oz per week) or 30 g raw nuts per day (15 g of walnuts, 7.5 g of hazelnuts, and 7.5 g of almonds), consumed for 5 years reduces the incidence of major cardiovascular events by 30% among persons at high cardiovascular risk 69. After 1 year, the same Mediterranean diet supplemented with 30 g raw nuts per day reduces waist circumference by 2 inches (5 cm) 70.
* Compared to consuming less than 1 serving/wk of raw nuts, people consuming 3 servings/wk (about 25 g/day) or more, have a 39% reduced risk for obesity, 26% reduced risk for the metabolic syndrome, and 13% reduced risk for diabetes 71. Higher consumption of raw nuts was also associated with a 32% lower risk of abdominal obesity 71.
* Consumption of raw walnuts, 2 servings (60 g) per week or more, compared with non-consumption or rare consumption, is associated with a 33% lower risk of type 2 diabetes 72.
* People with a high intake of flavonoids (which are health promoting substances found in fruits and vegetables), 360 mg/day, corresponding to 20 serving/week of fruits and 24 servings/wk of vegetables have been found to have a lower risk of fatal cardiovascular disease by 18%, compared to those with a low intake of 120 mg of flavonoids/day 73.
*High blood levels of omega-3 fatty acids (and by implication omega-3 fat intakes) are associated with 27% lower total mortality, especially from cardiovascular deaths 74. This mortality difference corresponds to 2.2 more years of remaining life after age 65 in people with higher versus lower omega-3 levels 74.
* Adhering to a healthy diet, characterized by high intakes of fruit, vegetables, fiber, fish/shellfish, and low intake of sugar, has been associated with a reduced incidence of cardiovascular (CV) events by 32% in and 27% in women 67.
* In a meta-analysis of over 300,000 American, Japanese, and Chinese middle-aged participants, higher dairy consumption (>3 servings/day versus <1 serving/day) was associated with a 15% reduced risk of type 2 diabetes 75. A dose-response analysis showed that the risk of type 2 diabetes could be reduced by 5% for each additional serving of total dairy products and by 10% for each additional serving of low-fat dairy products consumed 75.
* The combination of the main healthy lifestyle factors – maintaining a healthy weight, exercising regularly, eating healthy, and not smoking or abusing alcohol – seem to be associated with as much as an 80% reduction in the risk of developing the most common and deadly chronic diseases 76.
* Among individuals aged 70 to 90 years, adherence to a Mediterranean diet and healthy lifestyle with regular physical activity is associated with a more than 50% lower rate of all-causes and cause-specific mortality 77.
Anti-aging medicine was developed in response to the flaws of the traditional disease-oriented medical establishment. Supported by the above mentioned statistics and nutrition/exercise interventions, anti-aging medicine builds upon the power of lifestyle to prevent and possibly also treat many common chronic diseases that plague modern societies.
Anti-aging medicine is a new healthcare model that focuses on eliminating the causes behind diseases and preventing their development, rather than just treating symptoms of established diseases.
The key differences between anti-aging medicine and traditional medicine are:
1) Anti-aging medicine uses advanced diagnostic tests to detect precursors for well-established risk factors, and new emerging risk factors. Traditional medicine uses less advanced mainstream diagnostic tests which are not necessarily the most appropriate for the individual patient.
2) By detecting precursors for risk factors (both traditional and well-established), anti-aging medicine doctors can intervene with simple lifestyle interventions to target the causes of diseases. Traditional medicine instead intervenes with symptoms of diseases, which does not eliminate the causes of diseases. This is not effective in a long-term perspective, as medications often confer serious side effects (which often give rise to other complications) and are also expensive.
