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

Post marathon gain means I had no progress. Oh well better luck on the next one!


I'm in the same place only not as good of an excuse!

Wow, 4 days. Push!

Is this game stressing anyone else out? Between lots of exciting good stress (daughter graduating, college orientation overlapping, selling empty nest, buying condo, working full time, forget about dating) ... I thought it would be great time to be in control of food. Not happening. Is it just me?!


Not just you at all!


I thought I could keep momentum but this one will take something like a miracle to win. That being said I'm really going to try a mix it up to come out of this.

Well folks, some of you will be getting my money unless a weight loss miracle occurs this week!

Get ready for the final weigh in! Once the game ends tonight (Jun 9) at midnight PST, you have until 11:59PM PST on Jun 11 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!
