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

I have not seen the Amazon card email yet. Did those go out?


@VanTazTic Gift cards went out on 1/9. Yours was not yet collected so I just re-sent it to you.

Keep the momentum going! A new game has been set up for all players starting on Jan 12, 2019.

Good luck!

This was the worst pay out. I lost 8% and only got an extra 20. I really hope that means the rest of y'all crushed it harder than that. Cheers!

I don't understand the whole "bet big, win big" concept...was better off spreading my money on smaller bets.


The amount you lose doesn’t have anything to do with your payout. As long as you hit the 4% goal you get the same amount as anyone else who hit (or surpassed) their 4% goal. So everyone who ‘won’ got $120 back
But this just means lots of people stayed on track over Christmas so I think that’s a great thing!!!

Your game has now been finalized. Congratulations to the winners! You earned a 20.0% 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 $120.00 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…

Get ready for the final weigh in! Once the game ends tonight at midnight PST, you have until 11:59PM PST on Jan 6 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!


01/02/2019 9:33AM


Final weigh-ins start on Saturday and need to be completed by 11:59pm PDT on Sunday. Come back here Monday 2-3 hours after the game finalizes (but no sooner than 10am PDT) to see who won the bonus Amazon.com gift cards!


If you have troubles weighing in, switch from the app to the website or vice-versa. If you still have issues, email support@dietbet.com

Congratulations on your hard work so far! Keep the momentum going by joining your next game today.

If you want to reach bigger, long-term weight loss goals (with higher payouts!), join the Transformer! On average, players lose 24 lbs and win $325. If you're near your goal weight and ready to maintain, join the Maintainer to win money for keeping the pounds off!

Does anyone know when the latest time we can weigh ourselves on 1/6 is? I’m flying in from out of town that day and want to see if I will have time to weigh myself at home.


Midnight pst is the cutoff- you can find it in the rules section under ‘weigh out’
