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

Good luck to everyone!
Made it by 500 grams. So happy I didn't eat that sandwich before weigh-in.

Get ready for the final weigh-in for Round 5! Once the round ends on May 10 at midnight PST, you have until 11:59PM PST on May 12 to submit your final weight for the round.

Even if you're not a winner, you MUST submit your weight and photos proving you lost at least 6% in order to be eligible for Round 6 and the Grand Prize.

If you fail to submit a verified weigh-in showing the 6% weight loss, you will be disqualified. 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.)

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

I have been working really hard to make up for the two failed rounds, and am finally starting to believe in my ability to loose weight again! I really hope that I will make it, but at least I am doing all I can 😊 How is everyone else doing?

  • I hit my 50lbs lost mark this morning since starting this journey in earnest in July 2018. The first 10 took me less than a month, this most recent 10 took me a little over two months - but I did it! Still working for about 20 more - keep up the good work everyone!

50lbs in 9 months is amazing! My goal is 50lbs in 12 months. I've lost 20lbs so far.


That is so awesome!!! You are a real inspiration! You look beautiful!!!!

Three Transformers! Wow. Definitely a good way to stay accountable to your goals.


I am also in three transformers but I space them out about two months apart - I meant to say kickstarters...!

I had car accident last month and I let it derail me a little which was not very smart, and I just can’t seem to get my head back in this game. Now I’ve really gotta get to it to make around 5 weigh-in. Wish me luck!!!
