Summary

This study involves an evaluation of whether providing small incentives weekly for dietary self-monitoring and/or weight loss improves short- and long-term weight loss. Participants can expect to be on study for 18 months.

Detailed description

In this two-site, randomized, single-masked, longitudinal 2x2 factorial study, called Log2Lose, adults with obesity from Madison, WI and Durham, NC will be offered a 78 week, evidence-based behavioral weight management program comprising an incentivized weight loss intervention for 26 weeks (Phase I), an incentivized weight loss maintenance intervention for 26 weeks (Phase II), and a non-incentivized weight maintenance intervention for 26 weeks (Phase III). Participants will be randomized in a 2x2 design to receive adjunctive incentives for either weekly weight loss or dietary self-monitoring, both, or neither. The investigators will assess the proportion of participants achieving clinically significant weight loss of greater than or equal to 5 percent at the end of each phase. All participants will participate in an 18-month weight management program delivered via videoconference.
