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 863,364 DietBetters, 98.67% have lost weight during their challenges. Combined, they've lost 15,501,585 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

Update: I made it! Not sure on days like today if I love or hate DietBet! Haha, it certainly works for me!!

Ugh. 152.4...need to be 151.5. Going to fast until I get there. But I feel like it’s torture! Plus my scale only goes by 2’s, so I really need to get to 151.4! I did my workout already and that didn’t help. I have gone to the bathroom and clipped my nails! Haha hopefully it won’t be much longer until I can eat and drink!

Dont give up. You are still a winner if you made progress. Keep up the effort and you'll crush the next one.


The struggle is real! Keep putting in the work and don’t give up. You’ll get there!

Glad to win this one. Puts me at - 30 since June 1! Basically cut caloric sodas and only 300 calories after dinner, usually has 1000 or more.
