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 762,963 DietBetters, 93.75% have lost weight during their challenges. Combined, they've lost 12,034,150 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

Congratulations! We had 146 winners out of 190 players! Together we lost a total of 1,580 pounds! I'm super excited so many of you made your goal in my biggest game of the year! WAY TO GO! Because the win rate was very high, the payouts were lower than most games, but far more of you shared in the winnings because you made it to your goal, which is awesome!

See below for bonus prizes! Congratulations to all the winners!

Thank you! Do we need to do anything if we were one of the first 20 people who signed up (to get the Amazon gift card?)

$4 ????? Not worth the trouble to take the pictures and do the weigh in. How is it that there wasn't more money to distribute to the winners? Disappointed,

Too many winners (which is a good thing) . And DietBet’s cut. At least you lost some weight !!!

Keep the momentum going! A new game has been set up for all players starting on Feb 16, 2019.

Good luck!

We didn’t each win $104.11. We each won $4.11. We each put up $100 so that shouldn’t count as part of the winnings.

I think the $5 fee was so you could have official weigh-ins along the way. I thought you had to add the $5 to get a chance at the extra prizes in this game. But - really, I'm not sure. I think I might check out "Healthy Wager", because I do find that money motivates me to lose weight.
Gaining money, I mean, not losing money, lol

Gotcha .

Get ready for the final weigh in! Once the game ends tonight at midnight PST, you have until 11:59PM PST on Feb 10 to submit your final weight. If you're a winner, you'll be asked to submit photos and will get a new weigh-in word when you visit the weigh-in screens.

Submit early to make sure your photos are accepted, and remember - don't eat that cupcake until you get an email that your photos are approved! (If you don't get one, check your spam folder.) You must have an approved weigh-in in order to be declared a winner.

The game will finalize 24-36 hours after all weigh-ins have been submitted. Good luck!
