Primary aging is the progressive decline in health and fitness and depends on metabolic rate and oxidative stress. Untoward changes in body composition and metabolic function characterizes secondary aging. We hypothesize that both exercise and calorie restriction improve secondary aging, but only calorie restriction improves primary. However, calorie restriction followed with exercise is a superior strategy for overall healthy aging.
