Split the pot

10% is easier when you break it up, so each round has its own goal - and its own pot to split.
Check out the FAQ to learn more!

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

I forgot and I did not receive emails, so I missed the weigh in.

Referee Nancy ?

Bummer!! Definitely don’t rely on the emails. Check in here regularly, mark your calendar and/or set reminders on your phone. Its all worth it in the end! Good luck on your future goals!

Thank you Megan and the DietBet team for thoroughly reviewing my submissions and dealing with the situation after determining that there was in fact a glitch. DietBet has proven to be a reputable company.

It seems like every time I get close to winning, somehow it doesn't qualify. Screw this - if I wanted to be cheated like this, I'd drive for uber. I hate the new set up.

It's not a scheme, I followed the instructions and got paid??


You're right, it's not... they carefully reviewed the evidence and fixed the problem.

Woah, woah, woah. I sent in my pix by the deadline but I'm now seeing it looked like it was never received!! Anyone else going through this?? I'm well under the goal and should not lose the last most important round due to a glitch! What do I do???

How does it work if there is a glitch, and therefore additional winners, after winnings are announced?

Isn’t that annoying? I hate the new set up of how they give the word after the first pic.


I seriously can't get used to it!!

I DID IT...so happy and excited. I actually lost a few more pounds this month, so that is even more exciting. I'm considering joining another diet bet to keep me on task, but I think I will wait until November for after my half marathon. Good luck to everyone and congratulations.

I did not win this round, do I still need to submit my weight?

I don't think that you have to, but they would prefer that you do. Not sure if it would affect your winnings if you won previous rounds.
