Cut Calories by 15 Percent and You Age More Slowly


Reducing your caloric intake by 15 percent for two years slows the aging process and reduces your risk for age-related diseases, according to a new study from Pennington Biomedical Research Center at Louisiana State University in Baton Rouge.

In previous research involving animals, scientists found that calorie restriction can extend life. Now, this new study, called CALERIE (Comprehensive Assessment of Long-Term Effects of Reducing Intake of Energy), suggests this is also true in humans. This study was funded by the National Institute on Aging and conducted at three U.S. universities. It involved women between 25 and 45 and men between 25 and 50; about half were normal weight and half were overweight, but not obese.

According to the researchers, metabolic rates dropped significantly after one year on a reduced-calorie diet. In the second year of the study, this drop continued and resulted in a decrease in oxidative stress – a process linked to age-related conditions like diabetes, cancer, Alzheimer's disease, and others.
