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 908,084 DietBetters, 98.73% have lost weight during their challenges. Combined, they've lost 16,860,734 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

I am under my goal weight at final weigh in. Why did I not win ?

Did you submit a final weigh out and have it verified? I'd forward your verification email to customer support.

  • With a few days to spare! Honestly didn't think I would hit this goal...all last week scale wouldn't budge with 3.5 lbs to hit goal... then the last 3 days it kept dropping!

I reached my goal today, I.e after the usual 4 weeks but before 6 weeks. I believe this flex-bet is best for me as I don’t feel the urge to rush in order to lose weight, which is also probably a bit healthier. I’m going to try and find another flex-bet in March to continue my weight loss journey. Excited !

I want to do the weekly weigh in but I might not be at my goal and I don't want it to count as my weigh out. Does anybody know how that will work?

I didn't know that was an option, I've always been in some sort of game. Sounds like I can do that. Or, fingers crossed, maybe I'll make the goal here by Wednesday. :)

I’m glad I have chosen to be a member for it appears I’m still 0.4 kilo away from my goal. Thanks to this flexible game I’m pretty sure I’ll be able to reach it within 16 days. What a relief.

Update they fixed it woohoo! What had happened... Accidentally just weighed out (using a recently submitted weight) when I meant to for another game so it says I’m a runner up, so just emailed the coaches. I’m less than 2 lbs off so I’ll meet it with the remaining 2 weeks! Hope they can fix it... I’m a moron for not checking the game name.

Good for you. It seems that the referees/DietBet committee are very helpful. They always have been with me in the past. Thanks for sharing your story since I’m very well capable of doing things like that too :sweat_smile:


Following. I just did the same. But we still have several days left and I believe I too will hit my goal.

Was hoping to be able to weigh out for this game by Thursday morning, before my vacation starts.
Today, I am 1.6 lbs from my goal. Getting so close!!
I guess this will keep me honest while traveling!

I am curious, does anyone know why it says final weigh-in feb 16- March 2

Megan C.

It’s a member game so instead of 4% in only 4 weeks this one is 4% in 4-6 weeks so if you hit your goal weight anytime in that 4-6 week period you win. Member only games are more flexible to help you win and reward you for being a member

Jaimee a.

That makes sense. Thank you.
