Split the pot

10% is easier when you break it up, so each round has its own goal - and its own pot to split.

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 would like to start a Maintainer game. Do I just fill out the game form like for the ones for losing weight?

LOL. If I'm right, it was a long time ago so easy to forget! Let me see if I can find it because now I'm curious too. Maybe I just dreamed it. :)


Yup, they gave it away on March 10th and the winner was Jude A. It's kind of amazing how I can remember something like that, but not what I did at work yesterday...lol.

I made weight, but missed weigh in.:-( I thought I had until tonight to submit. Oh well. Better luck next time. :-(

Well, I finally got the scale moving the past several days after a two-month plateau, but it wasn't enough. Missed my final goal by a mere 1.3 pounds. 😢 But I've now lost a total of 180 pounds, so I honestly don't feel *too* bad. Congrats to all the winners, and to all of us who did our best. If you're feeling down, remember that the scale is not the only form of victory. 💪💗

That was odd. I had two dietbets end at the exact same time. I submitted the set of photos for that dietbet, and usually it asks me to use the same ones for any other pending dietbet weigh ins, but not this time. Not realizing this, I drank some juice and went up .2 lbs, but luckily, I'm way under my goal.

Either way, congratzs to all us! We made it! For some, we still have a bit further to go, but that's okay. We'll get there, too.

In my experience I had to wait until the weigh in was approved. Then it gave the option to apply the existing photos to any bet settling within 2 days.


Thinking about it, I think that's it. I just didn't want to chance missing the weigh in since it was so close to the cut off.

Well made the goal but up from last time. Anybody else have roller coaster weight? Lol

You did it though


I did! It was so stressful, because I was still recovering from pneumonia and not being able to exercise. So happy you managed to make the goal too!
