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 911,304 DietBetters, 98.74% have lost weight during their challenges. Combined, they've lost 16,987,008 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

You were so close. Think about what you accomplished.

Annaliese A.

That is very tough to be so close. It has happened to me, too. Give yourself a hug and be proud of the weight you did lose.
