Population aging is occurring worldwide due to increased longevity, declining fertility, and the aging of “baby boom”generations. The aging process involves numerous changes in body composition that affect health among which sarcopenic obesity is of clinical and functional significance. Aging-related sarcopenic obesity is closely related to lifestyle factors, including physical inactivity and inadequate dietary intake of proteins. Considerable evidence suggests that sarcopenia is a reversible cause of disability and could benefit from a lifestyle intervention. Thus, increasing protein intake (ranging 0.8 g/kg/day to 1.6 g/kg/day) in elderly population, especially among frail elderly population, is currently recommended to minimize declines in muscle mass and strength. Further, increased dietary intake of proteins combined with resistance exercise is widely accepted as the most effective intervention to slow the sarcopenic process of aging.
