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

Get ready for the final weigh in! Once the game ends tonight at midnight PST, you have until 11:59PM PST on Jun 15 to submit your final weight. If you're a winner, you'll be asked to submit photos and will get a new weigh-in word when you visit the weigh-in screens.

Submit early to make sure your photos are accepted, and remember - don't eat that cupcake until you get an email that your photos are approved! (If you don't get one, check your spam folder.) You must have an approved weigh-in in order to be declared a winner.

The game will finalize 24-36 hours after all weigh-ins have been submitted. Good luck!

Totally just asking but do we need a membership for an “official weigh-in?” My first shot at DietBet, I wagered $25 and got back $30ish. Less $5 for a one month membership, I essentially broke even. Then I bet again and ended up with $50ish; which I bet on this go-round. Suddenly I can’t do an official weigh-in without being prompted to spend - you guessed it - $50 on an annual membership. Trying to keep an open mind here but I’m starting to feel a bit scammed.

Yes. You have to have a membership to make “official” weigh ins during a game. Those official weigh ins just enter you in the weekly drawings. The only time you get a free official weigh in without membership is when you enter a game and for final weigh in for the game. Without a membership, you just do unofficial weigh ins during a game, which don’t enter you into weekly drawings.
I’m surprised it’s not offering you to just pay 5 dollars for a monthly membership. Maybe they only offer that when you enter a game?
