Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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).
