How do you verify the weight loss?

For all official weigh-ins, you'll be prompted to submit your official starting weight. Our standard weigh-in process involves you submitting 2 photos: one of you standing on a scale in lightweight clothing (no shoes, hats, belts, watches, coats, or outerwear), and another of the scale’s readout with your weigh-in word written on a piece of paper.

What you'll need

  • A scale (preferably digital)
  • A digital camera or smartphone
  • A full-length mirror or someone to take your photo

Does this actually work?

Out of 904,887 DietBetters, 98.7% have lost weight during their challenges. Combined, they've lost 16,752,306 lbs and won $62,263,235. In other words...yes.

All results shown on DietBet are from actual users. Individual results may vary.

Don't take our word for it

IF YOU LOVE DONALD TRUMP, this message is not for you. If you are "tired of winning" and are ready for a new administration AND you are ready to pick up a new game, I started a Kickstarter called "Dump Trump and other Gross Fat". I'm planning to try to use dietbet accountability to keep myself and other progressives doing something every week if not every day to try to save this country from the current administration. And of course, lose 4% at the same time. My plan will be to repeat the game every 35 days or so so you can double down on your winnings and your loss all the way to November 3! If you stay on track, weigh in in the evenings and weigh out in the mornings, you will set yourself up to with this transformer too.

If that doesn’t work, delete the app and reinstall it. I’ve had it happen to me twice. Good luck.

I started this game very late and only had 16 days to reach my goal. Had to fast almost every other day. It was super hard, won’t repeat this mistake again... but I did it:)))!!! Sorry I’m bragging, just feel really happy and hungry and going to treat myself tomorrow finally!!! And then join the next game 😀
Good luck to all!👍💪
