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

Only a few days left and we part ways. I thought it might be interesting to see everyone’s stats if they wanted to share. I changed my diet significantly, ate a mountain of fruits and vegetables, drank protein smoothies almost daily and stuck to pretty much chicken and fish. Exercised consisted of treadmill, and it shows I ran 247 miles, achieved 12,990 feet in elevation, and burned 35, 475 calories, but how accurate is a treadmill really. So how did everyone else do? Congratulations to completing this journey.

Congrats Edwin! I switched to a plant based diet, walk over 10K steps per day and strength training 2-3 days per week. Also had major surgery ( gallbladder removal) in January but recovered well and am still working toward my goals :)
