Lifestyle medicine is a branch of medicine dealing with research, prevention and treatment of disorders caused by lifestyle factors such as nutrition, physical inactivity, and chronic stress. In the clinic, major barriers to lifestyle counseling are that physicians feel ill prepared and are skeptical about their patients' receptivity.
There is now overwhelming evidence that lifestyle factors such as poor dietary patterns, physical inactivity, tobacco use, excessive alcohol consumption and psychosocial factors, e.g. chronic stress and lack of social support and community, are key proximal factors in the pathogenesis and incidence of NCDs. Lifestyle factors may also be more distal stressors, including economic, political or a high density population.
Hippocrates can be seen as the father of lifestyle medicine. He often used lifestyle modifications such as diet and exercise to treat diseases such as diabetes, what is today called lifestyle medicine. He is often quoted with "Let food be your medicine, and medicine be your food" and "Walking is man's best medicine".
