GoalTracker: Comparing Self-Monitoring Strategies for Weight Loss

Completed · Not applicable

Conditions studied: Obesity, Overweight, Weight Loss

In brief

This study is a randomized controlled trial that compares 3 self-monitoring approaches for weight loss. GoalTracker is a standalone, technology-based intervention using a commercial smartphone app (MyFitnessPal) and email. The investigators hypothesize that the group that delays diet tracking and receives additional intervention components (weekly personalized feedback, skills training, and action plans) will have greater weight loss at the end of the 12-week intervention and at 6-month followup, compared to (a) an intervention group that simultaneously tracks weight and diet for all 12 weeks and receives the same additional components, and (b) a control group that tracks only diet.
