We never post weigh-in photos and your actual weight is kept private by default.
You've now got 28 days to lose 4%. Use DietBet to post photos, comments, and get weight-loss tips. Make sure to invite friends to cheer you on.
Update your weight as often as you like. Self-reported weigh-ins during the game are unofficial but can help hold you accountable.
No Lose Guarantee!This guarantee ensures that if you win your dietbet, you won't lose money. Most winners make money but in the event that your game has an unusually high percentage of winners, we'll forfeit our cut in order to ensure that nobody loses money. So the worst case scenario is that you'll end up losing weight for free, which is still a big win.
