The purpose of this study is to evaluate the effectiveness of a technology-based system (the Body Media FIT system) for enhancing weight loss in severely obese individuals (BMI: ≥ 40 kg/m2). The investigators will compare two 6-month interventions: 1) a standard behavioral weight loss program (SBT) and 2) a standard behavioral weight loss program plus the use of the Body Media FIT system (SBT+FIT). The Body Media® FIT system is a novel weight loss tool consisting of an armband that measures energy expenditure, a digital display watch that provides "real time" physical activity and energy expenditure feedback, and access to a system website which allows individuals to track their food intake and set exercise and dietary goals. We will examine differences in physical activity, weight loss, and program adherence between groups.

| SBT + technology system (SBT+FIT) | Experimental | Participants will receive a standard behavioral weight loss program and will also be asked to use the Body Media FIT system as part of their weight loss intervention. |
|
| Standard behavioral treatment (SBT) | Experimental | Participants receive a standard behavioral weight loss program similar to that used in other large trials such as Look AHEAD and the Diabetes Prevention Program. |

| Standard behavioral treatment | Behavioral | Participants receive a standard behavioral weight loss program similar to that used in other large trials such as Look AHEAD and the Diabetes Prevention Program. Individuals will come to weekly group meetings for 6-months and will be instructed to reduce caloric intake, increase physical activity, and self-monitor their weight, eating, and exercise behaviors. |
