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

Does this actually work?

Out of 888,343 DietBetters, 98.73% have lost weight during their challenges. Combined, they've lost 16,006,156 lbs and won $62,263,235. In other words...yes.

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

Don't take our word for it

True, a bit underwhelming, compared to my past DietBets. But think of it as Amanda points out ... after all, high stakes games probably provides MORE motivation for participants to not lose their investment, so they probably work harder and a higher percentage succeed. :) I think that's kind of the idea.

I get you but I joined this bet to make money. I am motivated on my own.

My verification didn't get approved. I just found the email requesting me to resubmit my final weigh-in picture because my phone was partially blocking my face in the junk mail. So, I didn't resubmit, and now it's too late. This really sucks. I went hungry for two nights for nothing. So sad.

So sorry to hear.


Oh, no! That's AWFUL! Well, but you lost the weight, and really firmly keep in mind that THAT is the key, the core, the purpose, and your TRUE winnings!

People who've done these before: is that a good payout? Above, below or about average? Just curious.

Definitely much lower than my past payouts, but as Amanda says, it's a higher-percentage 'win' ratio in high-stakes games, I think.

Eric J.

For sure the higher the bet, the higher the win rate. My friend still think the win rate on this bet is higher than average for a 100 bet game by about 5%.

  • The game results will be posted Friday!

    I am planning on having the grand prize drawing completed by 12:00 PM (MST) on Friday, as long as the results are in by then. If the game results are not in by 12:00 PM, then I'll have the drawings posted about an hour after they do come in.

    Final grand prize drawing reminder:
    The final drawing will have all the game winners in it, and 2 names will be chosen randomly to win a bonus $100 Amazon gift card. Be sure to check back Friday to see if you won the grand prize drawing!

    **Also on Friday morning I will be sending out messages to the first 16 people that joined the game, to claim your $10 Amazon early sign up bonus!

This is the first 4% weight loss challenge I was successful on. I usually don't make it. Was worried it would happen again, but I watched my nutrition very closely both especially after breaking my toe and couldn't workout. Can't wait for it to heal so I can get back into the gym. To date since April, I have lost a total of 30 pounds. Time to collect my gift card from my coworker.

Sometimes I hate being a woman! I had made my goal of 157.8 when I hit 157.2 at the end of last week. But now it's that time of the month and I gained 4 pounds overnight! I waited as long as I could to weigh in, hoping I could get it down again but there was nothing I could do about the bloating and water weight! So frustrating because I know in 2 more days I'll be back to normal... :( :( :(
