It's not dieting. It's not betting.

DietBet is behavioral science in a game.
Loss aversion. Gamification. Accountability.
The best part: it works. Launched in 2013 as an experiment backed by research from Wharton and Brown Medical School, DietBet has helped over 800,000 people lose 10 million pounds and win over $60 million.
But it's more than just a game with money on the line. Ask a Dietbetter what makes this experience so powerfully effective, and the first thing they'll tell you is the community — how supportive it is, how helpful it is to make the journey with people who get you. It's a whole new approach to sustainable behavior change.
