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

Out of 716,335 DietBetters, 93.7% have lost weight during their challenges. Combined, they've lost 11,035,040 lbs and won $62,137,245. In other words...yes.

All results shown on DietBet are from actual users. Individual results may vary.

Your game has now been finalized. Congratulations to the winners! You earned a 50.8% 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 $45.25 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…

It’s all worth it in the long run! My total investment so far has been about $45 and I’ve made it all back and then some. Last month I bought 3 games and transferred $20 to my PayPal. This game helped me buy 2 games and I’m still waiting on two games to finalize!

Amanda P.

I feel like your buy in was much higher than mine if you only got $10 Iris! I feel fantastic about making $15.25 to lose weight I needed to lose anyway. I am already doing another diet bet at $25 because I have more weight to lose!

Hello, sorry this is nothing to do with this dietbet but I'm not sure where else to ask, could someone please explain how the transformer 6 month diet bets work, does £25 get taken out of your account every month? Do you have to do every month of the 6 months or could you say miss one if you was on holiday? Any info about how it works would be great thanks!

The weight targets for each month are set at the beginning. You can miss one, but you'll have to make the correct weight for the following month. You have to lose set percentages each month, off the top of my head, of initial weight, it goes 3%, 3%, 2, 1, 1, maintain for month six. By month five you must have lost 6% of your starting weight or you are disqualified (winnings are weighted towards month 6).


Okay great thank you everyone for your help :smile::smile:

I would way rather get the cooking stuff coming up (I do the cooking in my home for my wife and son) Along with going to the gym at 3:30 am till 5 then going to my great Gov Job (which I love) keeps my days and nights busy

I blew my first Dietbet. :( I lost 90% of my 4% goal the first two weeks. I had less than 2 lbs to lose the remainder of the month. I went on a road trip to Texas. Ate evil, delicious, sugary snacks the whole time. Cheeseburgers, tacos and BBQ! OH MY! I don't know why my mind tells me "It's ok, you're on vacation!"

I joined two more Dietbets today. I will redeem myself and eventually learn not to over-splurge when I'm on vacation!

Way to stay positive! You can do this! Don’t lose the things you love, but maybe learn portion control?


I barely made my goal for a similar reason..big concert with 4 people I love three nights before the final weigh in but I just kept telling myself if I didn’t make it that night was totally worth it. I bet your vaca was worth it and you’ll do great on your other dietbet. :)

Is it too late to submit a weight? Yesterday I was up over my goal, of course today I am under. I submitted again but not sure it will count. Oh the scale!

Congrats to everyone who won! I failed this time. Lost weight, but not enough. I didn't even submit a final weigh in because I didn't want to face the reality. ha. Feeling pretty discouraged because I worked hard and came up short, but I've already signed up for another one. I'll win that one if it kills me!

Way to stay positive! This is a journey that takes time, but the losses, no matter how small, are still a win, because we are dedicated to making this journey together, all of us, moving forward to a healthier and more fit body! Keep up the good work and don’t give up!

Mary S.

Failure is when you didn’t try. You tried and are a success in the attempt to better yourself. :)

This is my first DietBet. When do we typically learn the results? What's the most anyone has made off of one bet? I read that they only take 10 percent off for the owners to keep and then divvy up the rest with a group this large. With us all paying $50 a year.... I certainly hope it isn't more than that!!!

Congrats to all those who achieved their goal!Thanks for all the great comments and keep it UP!!!!

Excited to go celebrate my 25th Anniversary in VEGAS this week and then get back on the wagon when we return! YAY Dietbet! Hopefully Dietbet is helping pay for our trip!

The games usually seem to finalize the morning following the end of the weigh in period, I've only done one that finalized early. I'm guessing it's due to people either waiting until the last minute to weigh in then verifying those and also waiting on people who choose not to weigh in. I did 3 games simultaneously a couple of months ago and won $5.59, $7.44, and $22.87 on top of my initial bets.

Jennifer B.

I soon 2 so far, with payouts at $21.20 and $17.59 above what I paid in. I saw one that paid out $36 over initial bet!

Ready to bet on yourself?
