Split the pot

10% is easier when you break it up, so each round has its own goal - and its own pot to split.

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

3 days to go and a couple of lbs still to shift.
I have a dentist appointment tomorrow so a double incentive not to chew - I hope fillings aren’t too heavy 😂😂😂

Haha i was considering that option too especially as my hair has not been cut for months


Yall are too funny. I've been hovering around my goal. Never thought to remove hair or even a tooth. Lol

3 weeks of tea, congestion and a sinus infection has tested my determination to stay fit and lose lbs. At least my appetite has not betrayed me. Staying the course.

I’m starting my 3 day refresh tomorrow to help me with reaching my goal! So excited for it - it’s a gentle way to cleanse and detox the body and gut! Can’t wait to see the results and get back to eating healthy whole foods with lots of plant based proteins included!

Four days left and one pound left to lose. Any ideas on how I can prevent a weight fluctuation that affects my ending with a win?

And if that doesn’t work and you are still 1lb up do not despair an hours walk and stepping back on the scale might just be enough to shift that pesky 1lb - I’ve certainly had that work for me before

Honestly, I would dial back the carbs just for a couple days and drink some lemon in my water.

Still below goal but I ate like I've never seen food before in my entire life all week. Going to be super clean these next 6 days! Good luck all!

On July 29th at 5:00 AM EST, DietBet will be undergoing planned maintenance for app improvements. This will impact the app for a brief window that should be resolved within an hour.


During this timeframe, you will not have access to your game(s), which includes the ability to submit your weigh-in. Once the maintenance is complete, you will be able to resume normal activity within the app.


Please continue to reach your goals and email if you experience residual issues as a result of this maintenance. Sorry for the inconvenience!
