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 am doubling my efforts and my bet. I have a four month old baby and can't wait to lose some more of this baby weight!! " by Danell U.

Congrats to the goal weight winners. I fell short yet still victorious. I am now below 200 lbs. So, even though not a game winner this time, I am a health winner! All the best for the continuing journey everyone.

I am so excited that I made it to my goal weight. I’ve had a very challenging month at home but really stuck with my diet and am so happy to finally see the scale moving down instead of up!! Looking forward to my next challenge. And also, my weight was verified within 1 minute. No waiting for the confirmation, which was so nice!
