This study will evaluate the effectiveness of financial incentives and messaging tailored to individual goals and aspirations to promote and sustain weight loss. This is a 2-arm randomized controlled trial that will recruit eligible employees at a large university to participate in a 3-month weight loss program, followed by a 3-month follow-up period. The primary outcome will be change in autonomous motivation for weight loss.
