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

Is anyone leaning on AI (chatgpt?) for help with nutrition and fitness schedules? What's the best advice you've gotten from it so far?

Yes 100%! Just using chatGPT. I have a super simple kitchen scale for weighing out portions, I’ve found it’s super helpful to just give it a “I made this, here were the ingredients, I had xx grams” and it gives a pretty decent range of calories and protein! Also for advice when eating out, literally just upload screenshots of the entire menu and it gives good recommendations based on what you want (for me I usually target most efficient calories per gram of protein, others may just want lowest calories).

No I don’t use AI because I value the planet
