A blood draw and dual xray absorptiometry (DXA) measurement will also be performed on all patients. Participants will receive knowledge on their resting energy expenditure, body composition information, and overall indicators of health status including glucose and lipid levels. Study population includes healthy men and women, 35 to 60 years of age with a BMI equal to or greater than 25 and less than 40.
