Brief Summary
This study is one of three CALERIE trials that test the hypothesis that a reduced calorie, nutritionally sound diet improves biomarkers of aging and prevents some age-related chronic diseases such as cancer, diabetes, and cardiovascular disease. The three sites that are participating in the CALERIE trial represent a diversity of subject populations and interventional strategies.
