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 911,304 DietBetters, 99.13% have lost weight during their challenges. Combined, they've lost 17,149,257 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

I haven't seen anywhere who the 2nd fitbit winner is ... has anyone seen that and who was it?? Just curious! :)


I announced the winner. And the winner also posted a picture of the new Alta she received. The winner was TurboPurdy.

If you were a winner of a $20 gift card to Amazon during this challenge, I just sent the request for those to be purchased and sent to you via email. Be on the lookout!

This was my first Diet Bet, I met my goal yesterday and was so excited. This is the first time in a long time that I haven't started on a Monday fell off the wagon on Tuesday or Wednesday and just threw in the towel. Thank you Dietbet Jen for hosting this. Looking forward to the next game. :)
