Outcomes

Primary Outcome Measures

Change in Abdominal Fat Mass
Visceral adipose tissue (cm3) by MRI. Change is calculated as value at baseline minus value at 1 year

Secondary Outcome Measures

Cardiometabolic Risk Factors
We are reporting change in blood glucose. Change is calculated as value at baseline minus value at 1 year
Weight Change/Maintenance
The change in body weight at follow up of 1 year. Change is calculated as value at baseline minus value at 1 year

5. Study Description

Brief 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.
