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 did it! Surgery and all, with even a pound extra! I'm amazed. I thought I was sunk with having exercise taken away from me, but truth be told I'm glad the unexpected surgery came about - it made me be SO strict about my diet, I never cheated once. And the results I got! Wow!

Yeah!!!! Below goal by 0.6lbs which is a lot for me. But thanks to Isagenix to keep me on track.

I won my first dietbet! I lost the %4 plus 2.5 extra lbs on top of that. I'm just below/at my post-pregnancy weight for my 2nd. Now to get to where I was before I had my first! (That would be 20 lbs to shed). while I found this created a tiny bit of anxiety in me - I was weighing myself at least once a day - I almost feel addicted and I want to play more! I might do ONE more round.

You might consider doing a transformer instead of a kick starter. I signed up for this a few months into a transformer, and this one was waaay more stressful.

Monica L.

Thanks ladies. I understand you can play up to 3 games at once. Does that mean 3 kickstarted and 3 transformers? Or could it just be a combo like 2 kickstart era and a transformer??

Super exicted! I'm taking a short break from dietbet, but not taking a break from taking care of myself. Best wishes to each of you, and congratulations to everyone who lost weight!

I accidentally submitted my old weight instead of submitting my new weight and pics but now it won't let me post! Help what do I do?

Look at the top of the page. Mine says i can cancel and resubmit at the top. See if yours says the same.

Ena J.

Mine doesn't have that option. It says game over. I emailed them with my pics and current weight
