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

Hi y'all! Checking in because it's been a while and it's very quiet in here lately. 💕😊 Hope everyone is staying strong! 💪

I took a vacation a couple weeks ago and did a real doozie on my progress. So this past week I was back on point. And now, a week later, I'm back where I was pre-vacay. But I still have to play catch up if I want to meet my goal for September 18/19.

Cheers! And have a great week everyone! ☺

I’m really struggling with junk food cravings this month and scared to get on the scale. I’m really going to try to do better for the next 9 days and hope for the best! :)

Tammy, what's your plan to catch up? I have a bit of extra work to do this week too, but I dont know how I'm going to do it. I need some ideas.
