Physician-based primary care has thus far failed to address the obesity epidemic. In this randomized clinical trial of 200 obese patients with heart disease risk factors, the investigators will evaluate the impact of nurse and dietitian case management on weight loss and weight maintenance, as an adjunct to physician care. In addition, the investigators will test the incremental benefit of an environmental support strategy using community health workers to help patients navigate their home and neighborhood environments to achieve weight loss. The innovative intervention model developed and evaluated in this project has the potential to provide a blueprint for successful primary care-based obesity services
