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 hope for the best for all of you. I was borderline but you know what decided to arrive today which always increases it seems unreasonable, water, weight, etc. for me so I’m out! Still pressing forward!

I'm so so sorry Christy. But you are STILL healthier than you were last year! Keep being strong and working at it!
