Split the pot

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

WOAH we won more than $40! That’s by far the biggest payout I’ve seen so far for a game. I guess it means a lot of people didn’t make it. 😞

I believe it’s also because 100% of the pot was split. DietBet didn’t take a cut of it :)

Crystal, that's because it's a member game. And that's part of the lure of joining to become a member so when you play the member games a cut isn't taken away.

  • I barely made it..... But I screerd up when I went to weigh in I chose use previous way in and now it says I'm a runner-up not a winner. I can't remember who I contact or who the referees are to figure out how to fix that does anyone know?

I emailed way better using the contact link in the app under account when I did that and they updated it for me.

Yay I did it! Now to hopefully not undo my progress while I take a break until I join another game.

I guess I’m weighing in tomorrow. I didn’t leave enough floor space around my scale on my picture and have to resubmit. Now instead of under, I’m 0.7 over. Glad I didn’t have any big meals planned! I still need to keep going to win my other games!

I lost this game😞 I knew it even when I was doing the previous game - I think I must’ve put on a ton since the last game as I got so hungry, binged a few days and then just gave up:((. I don’t even want to weigh myself as I’m scared to see the number… So much effort for the past few months!
My membership is over in July, maybe I’ll come back again and start all over agin.. I’m even considering bariatric surgery, because this perpetual battle with myself is so exhausting and frustrating.

I tend to over do it when a game is over too, now I’m really struggling to meet my goals for my transformers after losing a few rounds. Just keep working on changing those self sabotaging habits!

It's the mental battle with ourselves that's the hardest. But it's the getting back up after a hard fall that counts.. Hope u find your balance soon.

Still managed to lose an ENTIRE pound this week even with having two cheat days! That puts me 1.8 pounds under my goal weight for this game!

I thought I’d blown it and wasn’t going to make it. I reduced my calories and did a partial juice fast, and was 1 pound under this morning! Now I just need to lose 4 more pounds for my transformer I’m way behind on! Round 4 is coming up, and I think I lost the last 2 rounds.

I weighed in this morning (June 8th) for another game. Will I be able to use that weigh in when this one finishes? Basically, how long can I "reuse" a weigh in?

Sapna P

Yes you can use it for 48h. You just have to choose "use previous weigh in"
