Summary

This online pilot weight loss study will explore the feasibility of recruiting individuals to an established online behavioral weight loss program of varying duration (4 months vs. 6 months), We will compare 6-month weight losses between the two programs of shorter and longer duration, respectively, and obtain data to characterize weight maintenance experiences and retention. Both groups will receive the same intervention; the only difference is the number of weeks the group will meet. Both groups will complete follow ups at 2, 4, 6, and 12 months (12 months after the study begins).

Interventions

BEHAVIORAL

Four Month Duration Online Behavioral Weight Loss Program

Participants meet weekly on line with other group participants for 16 weeks. The group-based online behavioral weight control program incorporates the elements of current thinking and empirical data on successful weight loss programs, including restricted calorie intake and increased physical activity. Key behavioral strategies to facilitate making sustained changes in dietary habits and activity patterns are introduced, promoted, and reinforced throughout the program. Weekly "group meetings" in a video chat forum led by an experienced group weight control counselor are the venue for the group process, and extensive web-based resources to support behavior changes are offered. The online groups are "closed" such that those individuals who start the group remain in that group for the duration of their participation. Weight loss counselor will provide feedback and encouragement to participants after reviewing food diaries via weekly emails.

BEHAVIORAL

Six Month Duration Online Behavioral Weight Loss Program

Participants meet weekly on line with other group participants for 24 weeks. The group-based online behavioral weight control program incorporates the elements of current thinking and empirical data on successful weight loss programs, including restricted calorie intake and increased physical activity. Key behavioral strategies to facilitate making sustained changes in dietary habits and activity patterns are introduced, promoted, and reinforced throughout the program.
