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 made it to Onederland! ✨🎉

    Officially under 200 lbs! 🙌 This journey hasn’t been easy, but every healthy choice, every workout, and every time I showed up (even when I didn’t feel like it) got me here.

    I’m proud, I’m grateful, and I’m just getting started. 💪💖

    Now, just 0.9 of one pound to go to win this DB!
