Recent medical problems in the world include the prevalence of obesity, diabetes and Metabolic syndrome (Met- S) in developed and developing countries [1]. In relation to this tendency, flailty and locomotive syndrome in the elderly have also increased, which are remarkable medical and social problems [2]. We have to develop urgent work for these matters. This article outlines and reviews the points of exercise, diet and psychology in the elderly. In the United States, more than a third of persons 65 years of age or older are obese, and this group constitutes a population vulnerable to adverse outcomes, because obesity exacerbates the age-related decline in physical function and causes frailty, resulting sarcopenia and osteopenia.
