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

Hubby bought personal training at an auction. We are each taking a few sessions. She is really good, but it's just ANNOYING to be sore. My attitude needs to improve. Choices!

Get ready for the final weigh in! Once the game ends tonight (Jan 28) at midnight PST, you have until 11:59PM PST on Jan 30 to submit your final weight. If you're a winner, you'll be asked to submit photos and will get a new weigh-in word when you visit the weigh-in screens. Submit early to make sure your photos are accepted. Remember - don't eat that cupcake until you get an email that your photos are approved! And don't forget to check your spam folder. You must have an approved weigh-in in order to be declared a winner.
Once all weigh ins are submitted, the game will finalize 24-36 hours after that. Good luck!
