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

My name is Elizabeth and I am 37 years old. This is my first Diet Bet and I am looking forward to the accountability while I go on vacation and to a wedding. I have been following WW since July and am down 80lbs. Hopefully this challenge will help me get more weight off before summer starts!

Hey Elizabeth! Welcome! This Diet Bet already steered me away from all the March Madness treats in my office - my mantra has to be if I didn't bring it, I can't eat it! :D

I'm trying to lose 65+ pounds of "baby weight". I've been pregnant 3 times in the last 3 years (had two, lost one 😔)...but my baby is going to be a year old in May and I realize that I can't keep saying "it's just baby weight" until my kids are in college.
