Split the pot

10% is easier when you break it up, so each round has its own goal - and its own pot to split.
Check out the FAQ to learn more!

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

if I didn't reach this months goal, do I still get the money from the ones where I did reach the goal? I am just on the edge :)

Also can't believe it's been 6 months already! Made it by a pound and some. So relieved.... ready to celebrate with a new outfit! (although a stack of pancakes is calling to me :)

Yay, finally caught up and won last round! Since starting my first DietBet and over the last 14 months, I am down 60.8 lbs. Lost the last 20 lbs. during "September Slimdown Transformer." Wishing the best for all!

Get ready for the final weigh-in for Round 6! This is the last weigh-in of the game! Once the game ends on Mar 17 at midnight PST, you have until 11:59PM PST on Mar 19 to submit your final weight for the round. This is the last time you will be able to record your weight in the game, so please submit a weigh-in even if you have not reached your 10% goal.

Once the weigh-in period begins, you will get a new weigh-in word when you visit the game. Submit early to make sure your photos are accepted, and 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 for this round.

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

Just a few days to weigh in! Push hard to be well below 10%!!! You are worth it!

You can do it!! I am below my goal but still terrified of a sudden gain.

Trina D.

I was under my goal, but am now right on it - it's muscle though.... I've been lifting weights and my waist is shrinking. Wondering if I should stop so I don't get any heavier!!
