New Clues to Low-Calorie Diets and Longer Life

Research has suggested that very low-calorie diets may increase life expectancy in animals, and now a new study in humans provides some important clues as to why this may occur.

In the new study, individuals who had higher metabolic rates — the amount of energy the body uses for normal body functions — were more likely to die early from natural causes than those who had lower metabolic rates.

The new findings appear in the Journal of Clinical Endocrinology & Metabolism.

Higher metabolic rates may accelerate the natural aging process via the production of damaging free radicals. These substances are linked to many diseases of aging and may promote organ damage.
