Lose 10%

in 6 months


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

  • Okay y’all! I fought myself on whether I would share this or not, but this is a group to encourage others so here we go! The pictures below are my very first dietbet picture from August and my one from this morning when I weighed in for my transformer I am doing! These are not your average edited Instagram photos... oh no lol. Fresh out of bed, haven’t brushed my hair, let’s weigh in before breakfast photos! I am sharing this not for compliments but to show that once you find what works for you, if you stick with it, it is for sure worth it! I have lost almost seventy pounds in the last six months and hope to lose another seventy, which is hard to even fathom! Reminding myself where I started and why I am doing this always helps motivate me. For the first month or two even after losing twenty or more pounds I struggled to see much change in the mirror. Reflecting on pictures helped me see my progress more than anything and know what I was doing was working. One of my proudest moments of my journey so far came when a pair of work pants that was too tight the first day of school nearly fell off one morning when I went to put them on. i am excited and proud to say that this girl will be shopping for a new wardrobe in the coming weeks, so if you are wondering why I do so many dietbets, you know what I’m saving for 😊! Anyways, I hope that this post at least helps one of you! Have a fabulous day friends!

We do...if you look at the pot for the last month it’s huge. Prob easier to read the help bit on their website than me explain on here. But essentially the idea is if you hit you final goal at that last check in the pay out is massive.

Thank you!

  • Making good progress - hope you all are smashing your goals!! I’m stoked I’m at 75% for the Feb weigh in - buckling down at the first of the year really helped and so does being double enrolled in Kickstarters!
