The purpose of this project is to establish a Center of Excellence in Research on Obesity that will focus on severe obesity. The prevalence of severe obesity (i.e., Class 2 and 3 obesity; body mass index \> 35 kg/m2 and 40 kg/m2) is increasing more rapidly than is overweight and Class 1 obesity. Treatment guidelines for severe obesity are uncertain. Three novel hypotheses regarding the pathogenesis of severe obesity will be tested: a) using non-invasive methods to measure energy expenditure; b) conducting an annotated lipomic search for bio-markers of impaired fat oxidation; and c) examining the role of obesity-induced inflammation as a cause for leptin resistance. Responses will also be measured following intervention with diet and activity.

This project addresses an important aspect of health disparity. The scientific inquiry as to causes of severe obesity seeks to determine if there is a differing metabolic disposition to obesity in AA compared to non-Hispanic White adults.
