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

Hit my goal for the month yesterday, but decided to wait to weight in.... Back up 1 lb today. Rats. But I'll get there! Last week was CRAZY at work, but this week I'm back to my routine of bulletproof coffee in the AM, then one meal at dinner time. Going to morph that into some extended fasting, which is the only way i lose weight these days. Let's do this!!!

I hit my goal weight a couple of days ago and then gained a pound. I lost it again. I think those minor fluctuations are normal. Stay with it! You'll do well!

Ha ha, I've been gaining and losing the same 1-5 lbs r2 years now, after initially losing 87 lbs. Just trying to get these last 20 lbs GONE.
