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

Made my weight and then some :) so proud of me for sticking through with it eventhough didn’t meet the weigh in in the first three rounds. This was a great way for keeping me accountable and who doesn’t want a little bit of extra cash for doing something great for their body?!

Exactly, I won Rounds 1, 2, and 6, and feel good. Down a few sizes and many have noticed.

I made my weight! But they said I didn’t. What do I do?! I’m so sad!

Definitely contact them.


Mine said this too but I got a payout not sure what the issue is

$287.53 was my pay out! I paid up front which means I won $162.53 for keeping myself in check and losing weight that I wanted to anyways. Congrats to anyone that lost weight, even if you didn't win, you still made a change and that's something to be proud of.

Congrats! My payout was $195.16, but I lost Rounds 3,4, and 5.

I accidentally requested a pay out to the wrong PayPal email is there anyway to contact someone in this diet that? And get this fixed?

Has anyone found their next db?
I like the 6 month programs, but was considering a 1-month “blitz.” And WIN$ for shopping season.
Plus, I want to use my winnings to get some new clothes!!! Yay! Not that $100’ish will go far, but buying pants 6” smaller than 6 months ago —>> PRICELESS!!!

Any suggestions??

I’m checking them out now. Love the name “Turkey Trot” I play a song on the guitar called “Flying Turkey Trot” by REO Speedwagon. Look it up - it’s a rocker. Been playing that tune on guitar since around 1979. :)

Does anyone know how long it takes to finalize the game? I was expecting it to be done by now.

Their post said it could take 24-36 hours.


The wait is over! Congrats all! Anyone joining another Transformer?

71 lbs down! 28ish lbs in this dietbet I am excited & thinking of doing another transformer. I got a bit lazy with this 1 & made it, thinking I need to push I feel great. This was an amazing process, I have enjoyed watching everyone's transformations. Anyone else thinking of doing this again?
