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

I'm sorry my auto correct.. I meant I actually weigh 258... I was so upset cause I didn't loose any weight. But I'm actually under the goal weight I needed for the bet. (260) I feel very proud of myself. Even though I'm not a confirmed winner and didn't get the $$$.. But I did loose 13 lbs in the 28 days

40 bucks, seems like you make more money with more people participating from the bet above participated in. Ahhh, on to the next one!

Has anyone done monthly bets, thoughts on them vs weekly ones?

If you're talking about The Transformer, instead of The Kickstarter, I highly recommend it. These 4% bets are great to knock away the early fluff. But the Transformer really cuts you down to size. The smaller goals spread out over a longer time frame are really easy to hit if you stick to a plan. If you're in it for the money, the $25/mo bets almost always double your investment, but if you want to lose more weight, find the high stakes games. Laying that much cash on the line seems to really kick people into gear.

Great, good info and thanks!!
