Brief summary: Investigators are conducting a randomized controlled trial with overweight and obese college students on the University of Minnesota campus. The primary outcome will be weight loss measured 12 months after study enrollment (corresponds to 10 months after the end of treatment).

Detailed description: Approximately 30% of college students are overweight or obese. Intervening on excess weight early may eliminate obesity-related morbidity. Evidence supports use of monetary incentives to encourage weight-loss; questions remain about the efficacy of contingency management on weight loss maintenance.

"Lose 2 Win" contests in which participants who achieve weight-loss goals are eligible for cash prizes, appear well-suited for implementation on campuses. Our objective in this two-phase trial is to evaluate the feasibility, acceptability and efficacy of Lose 2 Win for weight-loss maintenance among college students.
