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

The game has begun! Lose 4% by your final weigh-in, and you'll be a winner.

Remember that you can weigh in unofficially as often as you like before then - it'll help you stay accountable. (And don't be distracted if anyone appears to have super fast weight loss. There's no bonus points for losing weight the fastest, and only official, Referee-approved weigh-ins determine who wins.)

Good luck and have fun!

Dropping sugar and sugar substitutes from my diet to break my sweet tooth... technically yesterday was day 1, and it was SO hard... I expect to be grumpy for a few days, here...
