Less Calories, More Life
Can caloric restriction extend human lifespan? Copyright © Ian Williams Goddard Only one intervention has been proven to extend both the average and maximum lifespan of all animal species tested: reducing the consumption of dietary calories, or caloric restriction (CR). [1-2] While widely recommended, exercise and nutritional supplementation have not been shown to extend maximum lifespan. [3-5] Because CR extends maximum lifespan, scientists believe it actually slows the process of aging. CR is therefore used as a means to study the process of aging. [6,7] The graph to the left shows the lifespans of four groups of mice, illustrating the dramatic life extension induced by life-long CR. [8] The first group (green) were controls who ate freely without restriction and define normal lifespan. The other […]
