One of the first studies to explore the effects of calorie restriction on humans showed that cutting caloric intake by 15% for 2 years slowed aging and metabolism and protected against age-related disease. The study, which will appear 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.
