NCT00099138

Brief Summary

This study is one of three CALERIE trials that test the hypothesis that a reduced calorie, nutritionally sound diet increases the length of life 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.
