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

Man, that was tough! I got over-confident when I hit my goal weight early, slacked off a bit because of the holidays. I’m on vacation with my family and brought my scale. Barely hit my goal weight, but I’m so glad that I didn’t do my typical holiday weight gain this year! Feeling relieved and a bit proud.

After a discouraging week, I finally saw a little “whoosh” effect on the scale and dropped 1.4 pounds. Still have more to go to win this one. How’s everyone doing?

I'm hanging in there. It'll be a struggle to hit my goal next week, but I'm doing so much better than I would be if I hadn't joined this Diet Bet.

Ok, 14 days remaining and 2 pounds to go! Time to get focused. How’s everyone else doing?

Me too, 2.1 pounds to go. It's hard with the holidays, with all the treats around and the general disruption to my normal schedule (eating plan and exercise). Just trying to make sure I do well most days and not overindulge on days when there are holidays events.

Hit my goal weight last week, but am up a few lbs on the scale this week.

Did the Les Mills body pump class at my gym this morning and still had energy to roller skate with my kids this afternoon. Even though I’ve had a very stressful week and caved to some stress eating, it’s nice to see the results of exercising and being more active.

Happy to have a challenge over the holidays. Over the last two months I’ve retrained some healthy habits, exercising daily and tracking calories with success in two other DietBets. Didn’t want to lose momentum and the 4% over 8 weeks seemed like the perfect challenge.

- Most Liked Comment: "Love the new game! I was just telling my friend I was done with diet bet because it’s too aggressive and for many, not maintainable. I was having to lose 2 lbs a week to make goal. One pound is much more realistic and MAINTAINABLE. How does everyone else feel?

Get ready for the final weigh in! Once the game ends tonight at midnight PST, you have until 11:59PM PST on Jan 3 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!
