Overview

This trial is active, not recruiting.

Conditions obesity, diabetes, hypertension, hyperlipidemia
Treatments exercise only, reduced calorie diet, weight maintenance diet
Phase phase 3
Sponsor University of Alabama at Birmingham
Start date June 2010
End date January 2014
Trial size 180 participants
Trial identifier NCT00955903, F090430012

Summary

The investigators want to determine if the benefits of weight loss outweigh the potential risk in a group of older adults. The investigators will test the hypothesis that changes in diet composition alone or in conjunction with weight loss will have a significant effect on fat stores, and as a result, improve cardiometabolic risk factors and functional status in adults 65 and older.
