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

  • Cheers to completing the first 2 months and starting Round 3! May 18th 217.2lbs —> July 19th 204lbs. Down a total of 13.2lbs and feeling determined heading into Round 3- this is a big personal goal for me as my goal weight is set for 199.8. It’s almost ironic that is just .2 under 200 bc I have been chasing to be under 200 for almost 5 years and just keep letting myself backslide. Round 3 is going to be “the” round for me. So you’ll have to excuse me when I’m emotionally vomiting the next 4 wks - it’s going to be a wild ride of planning, will power, and determination to hit it with 2 trips planned in August. Let’s go!!

Thank you!!! I let myself enjoy the wknd and some treats and soaked up the win. Today it’s back to business and focused on the next milestone! We can do this one win at a time.
