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

Cheers to making it to the last Round and maintaining, possibly losing the allowed 12%, or getting that last little bit to hit your goal! Congratulations to everyone who hit goal this time! If you didn’t this round you still have 4wks to get to your 10%!! LFG!!

Oh my goodness - I was making good pace and then started eating Halloween candy about a week ago and barely made it in round 5. Finally cut off the candy on Saturday and needed to wait until today to weigh... I hope everyone stays focused for this last round!
