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 gained a few pounds instead of losing and am now so much more motivated for my 2017 goals. Many congrats to all those who lost weight this month!!!

If you enter a weight that isn't your goal the site closes and you can no longer enter anything

I didn't enter anything. I was close, but not close enough. Oh well, I still won because I lost... thanks Amy and everyone else for your support. See you in January!

Well I didn't win, but I lost a lot. Missed the goal by 2 lbs, but lost more than I have in a year, so I still won!

Moving and unpacking and being busy helped me at the end to reach goal. Yay!
