Calorie Restriction Appears Better Than Exercise At Slowing Primary Aging

Calorie Restriction Appears Better Than Exercise At Slowing Primary Aging: Previous research on mice and rats has shown that both calorie restriction and endurance exercise protect them against many chronic diseases including obesity, diabetes, cardiovascular disease and some types of cancer. However, the research has shown that only CR increases the animals' maximum lifespan by up to 50 percent. These animal studies suggest that leanness is a key factor in the prevention of age-associated disease, but reducing caloric intake is needed to slow down aging.
