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

The game has begun! Lose 10% by the end of the game, and you'll be a winner. Each Round also has it's own goal and its own pot to split. Your goal for Round 1 is 3%.

Keep yourself accountable by weighing in unofficially or by submitting progress weigh-ins through Membership. To reward players for consistency each Wednesday we’ll randomly reward an exciting progress prize to one or more players who submitted a Progress weigh-in during the 7 days leading up to the drawing. The first drawing will be on Jul 26.. Any official weigh-in’s submitted within the 7-day Progress weigh-in window will automatically apply as the weeks Progress weigh-in. Remember, that only official, Referee-verified weigh-ins determine who wins.

Good luck and have fun!

  • Hi everyone. I am in a celebratory mood this #TransformationTuesday - My January DietBet Transformer game ended yesterday and, while I am still waiting to see how much $$$ I won, I am a confirmed winner! Actually, I met the 10% goal more than 3 months ago. So much has changed for me over the last 6 months: I lost 71.8 pounds, I went through a cancer scare that resulted in two surgeries (I’m now pre-cancer/cancer free!), I was offered my dream job when I wasn’t even looking for a change, I left a job I’d loved for 16 years, I moved to a new city and now live close to my family and I am blessed to be President/CEO of an amazing organization. I am so very thankful for all that I’ve learned along the way and can’t wait to see what happens over the next 6 months. I started doing StepBets last week, an in a June DietBet Transformer game and I signed up for this DietBet Transformer today. My journey continues. Stay tuned...

I’ve got 70 lbs to lose but they gave me a goal of only 23.2 I’m definitely hoping to surpass that. Never done this so hoping to stay motivated . Are there recipe ideas posted anywhere ?

Try Paleo options. Many blogs and books. No sugars/ yucky carbs. We got this!

  • Rocked it for lunch today! Romaine lettuce and arugula with salmon, avocado, and a lemon juice/olive oil vinaigrette. Delish.

Wa-hoo! Was looking for a way to get my motivation up. Got the ideas and inspiration, but no motivation. Some friends of mine are doing this and love it. I will weigh-in tonight after work.

After motivations comes determination and that stays longer. I found my determination during my first diet bet. You'll do amazing.
