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 893,400 DietBetters, 98.73% have lost weight during their challenges. Combined, they've lost 16,340,577 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

- Most Liked Comment: "Get connected. Did you know that DietBetters who connect on Facebook and Twitter lose 20% more weight in the game? Why? When you announce your DietBet publicly, you're ratcheting up your commitment in a big way. It's a simple, free way to boost your success rate. (Note: DietBet never posts your actual weight, just your accomplishments.)" by DietBet

Get ready for the final weigh in! Once the game ends tonight (Jun 18) at midnight PST, you have until 11:59PM PST on Jun 20 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. Remember - don't eat that cupcake until you get an email that your photos are approved! And don't forget to check your spam folder. You must have an approved weigh-in in order to be declared a winner.

Once all weigh ins are submitted, the game will finalize 24-36 hours after that. Good luck!
