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

Has anyone’s money hit their PayPal account yet? Usually it goes in almost immediately but it’s not in there yet. Maybe the holiday has delayed it.

No. Waiting. Someone must have needed the extra verification

What game is everyone doing next?! I’m tempted to do a transformer but I’m nervous!

Angel this is the link to one that I’m doing that has over 4,000 people in it. This one is 28 days and it looks like it’s being hosted by a professional celebrity trainer.

Angel this is the link to the transformer DietBet I’m going to do that has $6,000 plus in prizes.

Next time when you’re that close, try a 36 hour water-only fast. For example, stop eating at 7pm, drink water throughout the next day, sleep, wake up, then weigh in. I lost a few pounds during that time. Sure, it was water weight, but it’s a great process for some detox and resetting your mind. Believe me, I love to eat, but this wasn’t as hard as I thought it was going to be, especially with all the Christmas treats floating around the office.

Thank you both and I was thinking about all water but I was driving back home and didn't want to keep stopping lol

There is definitely a difference! I'm sure you already know that we are our own worst critics. ;) Keep up the good work. You look fabublous!
