One of the first studies to explore the effects of calorie restriction on humans showed that cutting caloric intake by 15 percent for two years slowed aging and metabolism and protected against age-related disease.
The study, which appears March 22 in the journal Cell Metabolism, found that calorie restriction decreased systemic oxidative stress, which has been tied to age-related neurological conditions such as Alzheimer’s and Parkinson’s diseases, as well as cancer, diabetes, and others.
