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

  • This is huge for me- I struggle with eating 30/40/30 & I almost got it today- I weighed food- counted everything. Just 1% up in fats & missing in protein. I know from past experience that when I focus on protein and fiber mostly that it seems to work out well- I feel satisfied and full longer, have less cravings and more energy.

Great job! Damn near perfect, but who’s actually looking for perfection ;)

I find it difficult to hit the 30% protein too, even 25%! And I’m not a vegetarian. Good job!!! If you’re close to the % and within your calorie goal, I call that a win.
