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

Hi there! I've been thinking about what I really want/need to focus on this next month and I have a pretty hefty list I think.

Drink more water.
Take more steps.
Eat less sugar.
Eat more veggies.
Track my food intake.
Go to bed earlier.

What do you really want to focus on in the coming weeks? Let's help keep each other accountable. :)

Last chance to invite friends to join the game! Growing the pot adds to the fun for everyone. The player who gets the most friends to join each day becomes the game's Most Valuable Player, and we'll award an overall MVP once invitations can no longer be sent.
