Lifestyle Medicine, defined by the ACLM, is the use of evidence-based lifestyle therapeutic approaches, such as a predominantly whole food, plant-based diet, physical activity, adequate sleep, stress management, avoidance of risky substance abuse and other non-drug modalities, to prevent, treat, and, oftentimes, reverse chronic disease. The American Association of Colleges of Medicine has recognized the Lifestyle Medicine physician as one of the top five emerging careers in medicine today. Chronic diseases, including cardiovascular disease, cancer, metabolic disorders, and some chronic infections (e.g. HIV, tuberculosis) account for 80% disease burden and healthcare cost nationwide and worldwide. Research data has concluded that unhealthy lifestyle contributes more than 60% of the disease risk factors. Lifestyle medicine treats the root causes of chronic diseases, which is the future of medicine and true reform of healthcare system.
