NCT00664547

Brief Summary

The purpose of the trial was to examine the independent effects of equivalent diet- or exercise-induced weight loss on obesity and related cardiovascular health risk factors. We hypothesized that exercise would result in greater reductions in obesity and health risk factors that equivalent diet (caloric restriction).
