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

It’s crunch time for this diet bet. Good motivation for giving up all beer or wine, and this week going with protein drinks as some meal replacements. What surprised me was that they really satisfied my hunger. But it was hard last night watching my housemate eat the Crispy Rice and Shrimp leftovers 😢
Fingers crossed we all get good results today!
