Understanding the Pillars of Lifestyle Medicine

Disease burden reports from the CDC, WHO, and other health organizations have all concluded that the leading causes of mortality across the globe are diseases directly attributed to modifiable lifestyle habits. Over the last 50 years, the mortality and morbidity statistics for these diseases have progressively worsened.

Medical science and practice, as presently configured, has not moved the mortality indices for these deadly diseases: cancer, type 2 diabetes, hypertension, the heart disease that follows, degenerative brain disorders, and immune-reactive disease. We have continually pushed pills and procedures before any real consideration of preventing or addressing the fundamental causative factors behind these disorders.

There has been a shift in understanding since National Geographic's discovery of super-agers in five Blue Zones, the 2012 Nobel Prize-winning science of epigenetics, and the 2016 Nobel Prize-winning science of autophagy. All these revelations validate the fact that human healthspan can be optimized by changing our current, uncontrolled lifestyle habits through modification of the six pillars of healthy living.

Lifestyle medicine is the specialty that has taken a front-row seat in developed healthcare systems. There is frequently a tendency for people to confuse lifestyle medicine with holistic medicine, alternative medicine, or naturopathy. Lifestyle medicine is actually a branch of mainstream medicine that focuses on evidence-based prescription of lifestyle modification to prevent, manage, and reverse chronic disease.

Lifestyle medicine is founded on the idea that our daily habits and behaviors, such as diet, physical activity, stress management, sleep, tobacco and substance use, and social support, play a significant role in our overall health and well-being. Observational studies from the Blue Zones and structured prospective studies validate lifestyle's incontrovertible role in chronic disease and aging. The six pillars below are the factors that scientific evidence shows are key to achieving optimal health and longevity. Bringing them into daily life helps prevent and manage chronic disease, and improves quality of life.

1. Nutritious Diet

A nutritious diet is essential for overall health and longevity. It involves consuming a wide variety of whole, predominantly plant-based, unprocessed foods that provide the nutrients our bodies need: carbohydrates, proteins, fats, vitamins, and minerals from plant-based sources, and water. A nutritious diet should be rich in fruits, vegetables, whole grains, and lean proteins, and low in processed foods, added sugars, salt, and unhealthy fats. Following a nutritious diet reduces our risk of chronic diseases such as heart disease, diabetes, and certain cancers.

The Nurses' Health Study, as well as the Adventist Health Studies 1 and 2, followed populations for over 40 years and clearly distinguish the difference in healthspan patterns between vegans, vegetarians, and omnivores.

2. Physical Activity

Physical activity is an essential pillar of lifestyle medicine. It improves physical and mental health, reduces the risk of chronic disease, and improves quality of life. The CDC recommends that adults engage in at least 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity aerobic activity per week, along with muscle-strengthening activity at least two days per week.

Physical activity can be built into daily life through leisure activities, household chores, or structured exercise. It's important to avoid rigid 'exercise' programs that create unnecessary psychosocial pressure and reduce compliance. The better approach is to identify activities that are enjoyable and sustainable, so engagement stays consistent.

3. Stress Management

Stress is a natural response to challenging situations, but chronic stress negatively impacts physical and mental health, contributing to heart disease, high blood pressure, and depression. Effective stress management is essential for overall health and longevity. Techniques such as mindfulness, which largely comes down to learning to control and optimize breathing, along with other relaxation techniques and exercise, can help manage stress and maintain a healthy balance. It's essential to find what works for you and prioritize it in your daily routine.

4. Quality Sleep

Quality sleep is essential for overall health and well-being. It allows our bodies to repair and regenerate, and improves mental and physical performance. The National Sleep Foundation recommends adults aim for 7-9 hours of sleep per night. Irregular sleep patterns, exposure to artificial light, and caffeine and alcohol consumption can all impact sleep quality.

A consistent sleep schedule, a relaxing bedtime routine, and a sleep-friendly environment all help. Worth noting: the WHO has considered classifying night shift work as a potential carcinogen, since it disrupts the circadian rhythm and adversely affects healthy living.

5. Limit Tobacco and Substance Use

Tobacco and substance use significantly damage health and longevity. Smoking is the leading cause of preventable death and disease worldwide, raising the risk of heart disease, lung cancer, and stroke. Substance abuse can lead to addiction and a range of physical and mental health problems. Hard alcohol, and its ability to rapidly raise blood ethanol levels through inappropriate mobilization of hepatic alcohol dehydrogenase, has long been known to cause debilitating liver disease. Quitting tobacco, hard alcohol, and substance use is challenging, but the health benefits are significant.

6. Social Connections

Evidence suggests that social connection and happiness positively affect longevity. It's a gray area of medical science that's rarely discussed, yet observational studies have validated its significance to healthy living. People with strong social connections tend to live longer than those who are isolated. Social relationships provide emotional support that helps people cope with stress, and practical assistance, like help with tasks or transportation, that improves overall well-being.

Research has also found that people who report higher happiness and more positive emotion tend to live longer and have a lower risk of certain health conditions, including heart disease and depression. Happiness may protect health by reducing stress and promoting healthy behaviors like regular exercise and a healthy diet. The relationship between social connection, happiness, and longevity is complex, and shaped by genetics, lifestyle, and the broader social and cultural environment. Even so, maintaining strong social connections and striving for happiness is essential for general well-being and contributes to a longer, healthier life.

The Next Frontier of Medicine

Lifestyle medicine physicians and practitioners are trained in the fundamentals of these six pillars, using motivational interviewing and cognitive behavioral modification to deliver them to patients as therapy or prevention, grounded in evidence-based methodology.

The Mayor of New York recently mandated that all hospital systems in the city include lifestyle medicine as the first-line therapeutic intervention for the metabolic syndromes of obesity, type 2 diabetes, hypertension, dyslipidemia, cancer, and neurodegenerative disease.

Lifestyle medicine is the next frontier of medical practice, the new face of medicine, and at Triad Longevity Academy, we exist to expound these pillars in practical, reproducible, and simple ways for the benefit of our students and everyone we reach.
