Aging And Calorie Requirements
An interesting snippet from Medical News Today when taken in the context of calorie restriction for healthy life extension: "Studies show adults' caloric needs drop about 10 percent or more from about age 30 to age 65 and older. Some of that decline may reflect a relative lack of physical activity in the elderly, and some may represent the body's basal metabolism slowing during aging. Part of the reason is that the body loses muscle - a prime consumer of energy - during the senior years. ... These body changes are neither irreversible nor permanent. Many seniors are actually able to add muscle mass and function into their 90s. You can defy what normal aging does to body composition by a careful balancing of food intake, exercise and vitamins."
