About

The investigators have shown that adding an internet behavioral weight loss program to a statewide campaign improves weight loss outcomes. However, our follow-up data suggest that once the intervention is stopped, participants begin to experience weight regain. Thus, the purpose of this project is extend this line of work and pilot test health coaches and monetary incentives for weight loss maintenance. The investigators hypothesize that coaching and incentives will improve longer-term weight outcomes.

Shape Up Rhode Island

Active Comparator group

Description:

Individuals who join Shape Up Rhode Island 2013, enter our research study, and lose 5% of their initial body weight during the first two months of Shape Up will be randomized to one of the three maintenance interventions. If randomized to this treatment arm, participants will receive periodic newsletters throughout the 12 month trial.

Treatment:

Behavioral: Shape Up Rhode Island

Shape Up Rhode Island + Professional Coach + Incentives

Experimental group

Description:

Individuals who join Shape Up Rhode Island 2013, enter our research study, and lose 5% of their initial body weight during the first two months of Shape Up will be randomized to one of the three maintenance interventions. If randomized to this treatment arm, participants will receive a professional weight loss coach and will be incentivized for submitting information to their coach and meeting weight goals.

Treatment:
