Lifestyle medicine is an approach to healthcare and preventive medicine that focuses on lifestyle factors and their impact on health and well-being. It recognizes that many chronic diseases and health conditions are primarily caused by unhealthy lifestyle choices and habits, and seeks to address these root causes through lifestyle interventions.

The field of lifestyle medicine encompasses a range of areas, including nutrition, Circadian Rhythm/Entrainment, physical activity, Positive Psychology/Social Connections, sleep, and substances abuse such as tobacco and excessive alcohol. The goal is to promote healthy behaviors and empower individuals to make positive changes in their lives that can prevent and even reverse certain chronic conditions.

Lifestyle medicine takes a holistic approach, considering the interconnectedness of various lifestyle factors and their influence on overall health. It combines elements of preventive medicine, behavioral science, and clinical care to help individuals adopt healthier habits and reduce the risk of chronic diseases like obesity, diabetes, heart disease, certain cancers, and mental health disorders.
