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

Feeling positive about this round? My weight has been fluctuating a lot with quite a bit of exercise, but am hopeful. Early Jan weigh-in is going to be the real test! I tried this once before, a few years ago and failed. Good luck everyone.

Sorry to hear Debra V. Hope you are ok. Good luck to you in life which isn't just measured in weight, but :heart:

Debra - hoping the next month brings you more peace & rest. I’m also probably missing this round. I didn’t really think about the time of year & we’re faced with soo many festive foods. This is like the advanced level transformer doing it over the holidays
