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 just got back from the airport about 20 minutes ago after flying home from a two week trip where I had no access to a scale at all. I knew for sure that I was not going to make this round of the diet but, but to my surprise I blew past my goal for this round by 1.5 pounds! And that’s at the end of the day after flying for six hours. This really proves to me that it actually is a lifestyle change and not just some thing that’s temporary.
