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

  • Started the day off with a delicious smoothie, banana, pineapple, blueberries, strawberries, Greek yoghurt, spinach and protein powder. Basically tasted like the melted slurry at the bottom of a banana split without the added 2000 calories.

    I can’t be the only one changing up my diet, give me some of your changes, I figure the more healthy options we all have the better chance at success for us all.

That looks great! I’m focusing on on whole foods. Usually an egg w veggies for breakfast, chicken salad for lunch and veggies w beans and rice for dinner. I’ve lost 70 lbs so far and have 40 more to go to reach my goal

That looks great! I joined late, so am just starting off, but am doing banana, spinach protein smoothies and/or hard boiled eggs for breakfast, salads for lunch, and will just focus on lean meats/seafood and lots of veggies for dinner this week.
