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

  • Still on vacation so I haven’t seen a scale in awhile… and I’m not encouraged.

    On the plus side, I’m having an amazing time in Australia, so there’s that!

    Here’s a funny, hope you have an amazing day yourself!

I always know I’ve been off track when I’m not looking forward to seeing the scale! I haven’t check my weight in a couple weeks now…. Exercise is going well but diet..:: yeah not so much. Enjoy your vacation!! Australia sounds amazing!!

  • Thank you Kasandra. , you’ve reminded me to do better with my eating as well. We saw this Kookaburra in the Sydney botanical gardens when we went to the Opera House.
