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

All results shown on DietBet are from actual users. Individual results may vary.

Last chance to invite friends to join the game! Growing the pot adds to the fun for everyone. The player who gets the most friends to join each day becomes the game's Most Valuable Player, and we'll award an overall MVP once invitations can no longer be sent.

Blah! I am at the highest weight that I've ever been at in my life- I had a botched c-section almost 2 years ago and my weight has been steadily climbing since then. I am ready to feel comfortable in my own skin again.
