Split the pot

10% is easier when you break it up, so each round has its own goal - and its own pot to split.
Check out the FAQ to learn more!

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

Have you come any closer to offering a maintenance game? Because of health issues I should not lose another 4%. I have really enjoyed this weight lost journey and the support from everyone.

Yeah that. That's awesome. " by Jaime M.

Drove through the snowstorm in the midwest to get home and weigh-in tonight--whew!

I'll miss the inspiration of daily updates about all the great walking, running, and workouts you all do--and the fun of tackling this challenge with you all.

I wish you all a healthy and happy ever-after; I'm glad I got to share this journey with you!
