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

  • Who else does great during the week, then Friday evening through Sunday has a harder time staying on track? We have a get together tonight & a group campout tomorrow. I’m telling myself to plan my meals, limit alcohol and get exercise in. I know I can do it- Stay the course. I don’t want to let the weekend ruin the awesome week I’ve worked hard for. I’m going to give this recipe a try.

Let me know how this tastes. I love cookie dough.
