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

Gained weight last month. Lost 7% this year so I guess I am still in the running for the grand prize but I didn't feel like being good in the past week. Pizza and beer. That's the problem with my dieting, I reward myself when I am almost to my goal. So, at least half of my weight is excess hydration. Only need to lose 2-3% in the next month. Very doable. Need to double down with a new contest.

I was so so close on Friday. And then lost my total mind Saturday and couldn’t get it back together by Tuesday. But we can totally do this!
