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

  2. How we prevent cheating +

Does this actually work?

Out of 702,461 DietBetters, 93.71% have lost weight during their challenges. Combined, they've lost 10,713,366 lbs and won $59,585,631. In other words...yes.

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

Don't take our word for it

I just stumbled upon DietBet yesterday and decided to join... anyone from the Seattle/Bellevue area? Any Peloton riders?

OK - I'm doubling-down with this kickstarter on top of the Transformer I started today! Ashamed of how far I've let myself go this last year. Need this kick-in-the-butt motivation to get back on track. Starting from my highest weight ever....no where to go but DOWN ;)

It comes back too fast, that is for sure. I really need to get back at it too. This year is almost over already! I am glad that you've joined us. You've got this!

Was gonna go to the gym but after an hour of making boodles (butternut squash noodles ;p) with this spiralizer, I'm sweating and my arms are shaking with fatigue lmao! I kid, I'm still going to the gym, but dannnnng. That should really be considered a workout.

On another note, I'm truly stunned at how quickly I already feel better not eating sugar again and exercising. My brain feels so clear, I don't feel tired, and I'm excited to weigh in on Friday. I have a good feeling..

Ha, that is awesome! Way to go on ditching sugar and exercising. Cutting sugar is so difficult but really makes a difference. You've got this!
