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

Congratulations! We had 95 winners out of 126 players! Together we lost a total of 1,004 pounds! I'm super excited so many of you made your goal! WAY TO GO! This game had a higher success rate then the other recent games, so payouts were a bit lower. I'm sorry there's not as much money for each of you but I'm glad more of you succeeded!

See below for bonus prizes! Congratulations to all the winners!

Have they been sent? I don't believe I received anything.


@Meg - There were problems with my order, I am working with Amazon to resolve. They should all make it out on Saturday.

Your game has now been finalized. Congratulations to the winners! You earned a 6.1% return on your money simply by investing in your own health. Don’t you wish all of your investments paid out at that rate of return?

The $106.11 in winnings will be deposited as points into your account. They can be used for a new game, or you can request a PayPal payout and treat yourself–you earned it! Payouts process within 24 hours. As promised, here are the top player titles. Drum roll, please…

Weigh in submitted, and already spent my winnings on 2 new bathing suits! Didn't even think I'd be wearing a bathing suit this summer as I had a baby in November. Thanks to diet bet for keeping me motivated!

Get ready for the final weigh in! Once the game ends tonight at midnight PST, you have until 11:59PM PST on Apr 7 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!

I forget. Does this mean we cannot do the final weigh in until midnight tonight?


It should be after midnight tonight.
