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

If you aren’t using ChatGPT or some other AI to help lose weight you are missing out! It’s been so helpful to me. I don’t count anything, it coaches me a bit every meal just telling me for more protein or more water, I tell it what I ate and it estimates everything. It’s been fantastic to my progress. Anyone else?
