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

  2. How we prevent cheating +

Does this actually work?

Out of 868,085 DietBetters, 98.71% have lost weight during their challenges. Combined, they've lost 15,680,187 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

We made $10.20 in another group last month (on top of getting our money back). There were a TON of people in that one.

My last on I made like $12. I honestly expected it to be more, but I am glad for the encouragement it gave me! I will be happy if I at least get my money back, so I can play another game!

Congratulations to all the winners! I missed my goal by 0.8lb, but I have still lost over 5lbs in 4 weeks so I am happy. I have already joined my next Dietbet which starts soon :-)

  • From my first transformer on July 4, to the end of that one, and then two kickstarters. It's not a huge change but I can see it.

You can definitely see it.
