Summary

This study aims to test two strategies for weight loss maintenance. It involves two phases, a weight loss phase and a maintenance phase. During Phase I (the weight loss phase), participants will receive a 16-week, Web-based behavioral weight loss program that involves access to weekly weight loss information and weekly personalized feedback on diet, activity, and weight loss goals. Individuals who lose at least 5% of their initial body weight during this program, will be invited to participate in Phase II. During Phase II, two 4-month treatments for weight loss maintenance will be tested. At the beginning of Phase II, participants will be randomly assigned to one of the two maintenance programs: (1) a behavioral maintenance program that involves in-person group meetings plus daily exercises in which information about a healthy lifestyle is reviewed or (2) a behavioral maintenance program that involves in-person group meetings plus daily exercises in which descriptions of positive future events are reviewed. Throughout the study, participants will complete assessments that examine the effects of the interventions on delay discounting, physical activity, weight, and other important health and psychosocial outcomes.

Type	Name	Description
BEHAVIORAL	Weight Loss Maintenance + Healthy Thinking	Contingent upon participants losing 5% of body weight or more in Phase I (weight loss) of this trial, participants will receive a 4-month behavioral weight maintenance intervention consisting of 7 sessions that focus on evidence-based weight management strategies focused on diet, exercise, and behavioral skills. In this treatment, participants will be asked to read short passages related to nutrition and a healthy lifestyle through our study website twice a day for the duration of treatment.
BEHAVIORAL	Weight Loss Maintenance Treatment + Future Thinking	Contingent upon participants losing 5% of body weight or more in Phase I (weight loss) of this trial, participants will receive a 4-month behavioral weight maintenance intervention consisting of 7 sessions that focus on evidence-based weight management strategies focused on diet, exercise, and behavioral skills. In this treatment, participants will create descriptions of upcoming positive events and will be asked to read short passages through our study website at least twice a day for the duration of treatment.
