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.

Only two days left in the year. Instead of waiting until the 1st to start your resolutions, get a head start now and start January 1st not at a stop, but running full steam ahead!

Final weigh-ins begin on Saturday and need to be completed by 11:59pm Pacific Time on Sunday. Come back here Monday afternoon to see who won the bonus gift cards!

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

Here are some tips to make it over the finish line if you are close:

- Watch your carb and salt intake

- Drink plenty of water

- You often weigh the least in the morning before you eat meals for the day

Best wishes!

Curious if the sign up bonuses are automatically distributed, or do folks need to contact you on how to redeem?


All bonus prize winners are announced here on Monday with instructions on how to receive their bonus. They must follow the instructions to get their bonus.

So do we submit our weight in on the 1st or any time until the end of 3rd?

Luis Eduardo and Jean C. like this comment.


The final day of the game is the 1st, and the final weigh-ins are the two days after that, so you can do you final weigh-in from January 2nd 12:01am - January 3rd 11:59pm Pacific Time.

So I only have to submit my weigh in by the end of the month right?

Yes! The extra weigh ins are for additional prizes but you have to pay the membership fee to qualify.

Tiffany O. is the overall MVP of the game! They invited 1 friend.

Why 117.65 in winnings? If 10000 divided by 67 is 149 usd


DietBet's cut is 20% of the total pot to pay for all expenses of running the games.

Keep the momentum going! A new game has been set up for all players starting on Jan 09, 2021.

Good luck!

Get ready for the final weigh in! Once the game ends tonight at midnight PST, you have until 11:59PM PST on Jan 3 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!
