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
