Lifestyle medicine (LM) is a branch of medicine focused on preventive healthcare and self-care dealing with prevention, research, education, and treatment of disorders caused by lifestyle factors and preventable causes of death such as nutrition, physical inactivity, chronic stress, and self-destructive behaviors including the consumption of tobacco products and drug or alcohol abuse. The goal of LM is to improve individuals' health and wellbeing by applying the 6 pillars of lifestyle medicine (nutrition, regular physical activity, restorative sleep, stress management, avoidance of risky substances, and positive social connection) to prevent chronic conditions such as cardiovascular diseases, diabetes, metabolic syndrome and obesity.
Lifestyle medicine focuses on educating and motivating patients to improve the quality of their lives by changing personal habits and behaviors around the use of healthier diets which minimize ultra-processed foods such as a Mediterranean diet or whole food, plant-predominant dietary patterns. Poor lifestyle choices like dietary patterns, physical inactivity, tobacco use, alcohol addiction and dependence, drug addiction and dependence, as well as psychosocial factors, e.g. chronic stress and lack of social support and community, contribute to chronic disease. In the clinic, major barriers to lifestyle counseling are that physicians feel ill-prepared and are skeptical about their patients' receptivity. However, by encouraging healthy decisions, illnesses can be prevented or better managed in the long-term.
