NCT01330329

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Change in body weight

    6-months

Secondary Outcomes (1)

  • Change in physical activity

    6-months

Study Arms (2)

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.

Behavioral: SBT + technology system (SBT+FIT)

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.

Behavioral: Standard behavioral treatment

Interventions

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.

Standard behavioral treatment (SBT)

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. 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. Participants in this group will also wear an armband that measures energy expenditure and they will log their food intake on the internet.
