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

Round 1 has ended! It's time to submit your official weigh-in for this round so you can start collecting cash if you win.

That means we're into Round 2! 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 next drawing is on Oct 9.. 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. Your goal for Round 2 is 6% of your initial weight. Good luck!

So the challenge for me is, I tend to start losing slowly because I often gain muscle and then start losing fat and most of this well this game most of the weight needs to be lost like the first couple rounds like it’s very waited heavily at the beginning and so I’m trying to figure out what this looks like for people who are more likely to lose all the weight and are most of the weight in round three and four versus one and two can I still win the game if I don’t lose the goal wait for round one in round one?
