Dr. Heymsfield's research focuses primarily on human obesity, including energy balance regulation, weight loss treatments, co-morbidity effects, and development of related mathematical models. He also has a long term interest in the development of methods for evaluating body composition and the application of new technologies such as fMRI and PET to the study of human metabolism.
