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

My goal was 7.4 pounds. I lost 9.4. It was verified that I met my goal yesterday and now it says I didn't reach my goal? This was a ripoff since I did what I was supposed to. Guess I won't do this again.

4% of my weight was 7.4 pounds, I lost 9.4 so how did I not reach my goal? I won't be doing this ever again. What a ripoff.

ARGHH!!! Missed it by .4 pounds. If only........ But on the other hand, I lost 6.5 pounds, increased my daily run to 5 miles in 1 hour, pushups are up to 44 (regular not the ladies) and I feel great. My clothes fit better. Just wish some of the 60 players would have posted. Or maybe my app isn't working correctly?


.4 pounds is so very little. I'm sorry you didn't win, but losing 6.5 pounds is a huge win in my book! Plus you feel better and look better. Congrats on finishing strong and winning at life!

This was tough to do. Bought myself a FitBit to be sure I was getting in my steps and super strict diet over the last couple of weeks. Well worth it to get me started on my weight loss goal of losing 25 pounds.

Get ready for the final weigh in! Once the game ends tonight (Oct 11) at midnight PST, you have until 11:59PM PST on Oct 13 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!

Walked 4 miles last night. Also made a veggie soup for dinner. Zucchini, green beans, carrots, onions, tomato, cabbage. I've discovered grains make me gain weight, so I've been avoiding most of them.

Excess calories make you gain weight, from grains or any other food. :)


Yes, absolutely true.
