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

How is everyone doing? This second weigh in will be a close one for me. It will probably come down to the wire before I’ll know if I meet this mini goal. When I signed up for this longer weight loss bet, I had thought I could work on losing 1/2-1 pounds a week not realizing the first couple of check ins required more significant weight loss. My grehlin is definitely up this week!

Stephanie M, Katie H, and Em: Hope you are feeling better about your weights as we get near the goal! Get a lot more steps in these lat days- a lot! Good luck!

I made it, though perhaps not in the fashion I would recommend. Came down with appendicitis this past weekend and once the inflammation came down after my return from the hospital on Thursday, I was at a weight I could submit for this weekend. Glad we all have a bit of a reprieve for our next weigh ins without having such a steep loss expectation.
