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 141 winners out of 188 players! Together we lost a total of 1,473 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!

I didn’t get my gift card yet. How do I get it. Yes I did send the email.


@heather - Your email was stuck in my spam folder. Just ordered it so Amazon should send it to you in a few minutes.

Your game has now been finalized. Congratulations to the winners! You earned a 6.7% 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 $106.67 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…

- Most Liked Comment: "Hi! I wanted to introduce myself and maybe others can too. 😊 My name is Sarah and I live in New Hampshire. I had gastric bypass in 2016. I started at 392 lbs and lost almost exactly 200! Unfortunately over last summer I had major health issues, including a major lung collapse and LAM (lymphangioleiomyomatosis) disease diagnosis, and regained some weight now that I can't do much for exercise (I'm on oxygen to sleep and any time I'm not just sitting). I have to drop about 30lbs to be a healthy BMI and be approved for a potential future lung transplant so this is very important. Also, my girlfriend proposed in January so I want to be the most healthy beautiful bride possible! 😊 Let's do this! 💪 " by Sarah

Excited to complete my first DietBet challenge. A little nervous about making sure I record my finish weight correctly with photos etc. Any helpful instructions?

You are correct. 4% means I would have to lose more than 5 pounds in 4 weeks. That would be very difficult for me. Can’t decide if I should take the risk just to keep me on track. Anne - thanks for the support. Good luck on your weight loss journey.

Yes, I'll join again right away. April-May great time to lose weight in prep for summer vacations :)

Weighed in and waiting approval. Lost more than the goal total but still have quite a bit more to go! Thanks fellow gamers for being an source of inspiration and motivation to succeed. Hope all achieved or at least got closer to your goal.

Weigh in approved! Lost the original 4% + 10lbs. Betting big really motivated me to push harder. I am joining my next bet tomorrow!
