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 haven't won a dietbet yet but set a goal for myself that I want to win one before my birthday. I finished 75 day hard challenge over the summer and since ending it I've found myself not giving priority to being healthy so I'm hoping this will help keep me accountable and back on track!
