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

Only a couple more days!! Let’s get those steps and water in! Let’s eat super clean, and I’m going to do a 18 hour fast! With some green tea and water! I only am about 3 lbs away! How is everyone’s progress?

Tell me more about drinking green tea. How does that help? Thanks


@heart I really think it helps digest everything I eat faster it makes me “go” more and it’s something to switch up from water as well but I also count it as my water because it’s just a tea bag!

Get ready for the final weigh in! Once the game ends tonight at midnight PST, you have until 11:59PM PST on Sep 10 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, and remember - don't eat that cupcake until you get an email that your photos are approved! (If you don't get one, check your spam folder.) You must have an approved weigh-in in order to be declared a winner.

The game will finalize 24-36 hours after all weigh-ins have been submitted. Good luck!
