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

I'm just going to throw this out there for any women who are as frustrated as I am at the moment.

Each week of weigh-in I've gotten my cycle. I'm actively trying to lose weight and my body is going against me by producing more.

To make matters worse. I'm in Peri so my cycles are unpredictable.

Last week I was completely going to win this round as well. This morning I weighed in barely too much. Now I have to struggle and work harder today and tomorrow to get back to just squeak by.

I am so incredibly frustrated.
