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

Congrats to all of you even if you didn't win the game you won because you got motivated,pushed yourself to limits you usually do not, and self control in avoiding them sinful foods, This was a hard one being around the holidays where goodies are in our face just about everyday. I myself lost over 7Lbs since. To my friend who host this thanks. Thanks to everyone for the challenge. We have made a start so continue to finish. See some of you next game. ;)
