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

Wow, fastest weight verification ever (about 3 minutes!), I made it! Congrats to everyone who lost weight and stuck to healthy habits this time around, even if you did not win. This was my last for a while, my goal will be maintenance while I have hip surgery in July or August (the sooner the better, but the surgery schedule is full!). Thanks for all the support and encouragement!

Best of luck with your surgery!

Thanks everyone, it turns out they had a cancellation so I will be in surgery next week and then can start the healing process. It is scary, but it is what I need to do to be healthy. Keep up the hard work everyone, especially those of you starting new diet bets or continuing other ones. You can do it.
