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

Well, I didn't make my final weight but I'm well under the 6% needed to still qualify for the last round!!! I'm only about 1.2 lbs away from that. I'll take it. I know I'll demolish my final weight goal!! Good luck to you all!!
