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.

Don't take our word for it

So i did my weigh in and They said that they couldn’t verify my pictures so I took another one for the final way in and they told me again that I couldn’t so I missed the final way in and I would like to talk with someone about this so if anybody can give me a message then I would really appreciate it. I worked really hard to lose the weight and I was little over a kilo more than my goal weight. I have been super excited throughout this whole month doing the diet bet and i honestly feel as if i have been scammer. I would really like to talk woth someone about this situation.

Hey Everyone. First time DBer here. What’s usually the turnaround time to payout?

You’ll get an email. This one is really slow, I finished another dB at the same time, weighed out this one first but the other one got verified first and the other one was finalised this morning!

Yessss how much longer??


So they have 24 to 48 hours from the time weigh in ended according to the rules, however if someone weighed in right near the end and they have to do a video verification they are given an extra 12 hours if I'm reading the rules correctly...

So annoyed. Hit my goal by 2 pounds but forgot my final weigh in!

me too Jason, I thought I could do it in the morning of 9/11/18 and realized too late that I missed the window. It happens. At least we lost the weight right?

I made it by just .1 lbs !! . The journey so far was soo good . My running improved (9.6 mins/mile ) and picked up some clean eating ,no junk food. Thanks Tony and Dietbet.

  • I missed by .3 but DietBet has been wonderful, supportive and fun! I went out in a swimming suit last week. Hadn’t done that in years. My genetics make me too slow a loser to win at this but I’m so proud to get this far (5 1/2 pounds!!) I will keep this going, 1lb a week but if I falter, I’ll be back! Thanks everyone! 💖

  • I gained weight during this bet, so I won't be getting any money, but I'm still walking away a winner. The scale only tells a fraction of the story. Where I am now mentally and physically (did max hammer strength with 20 lb weights) outweighs the money I lost
