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

Proud of everyone that participated in this! Even if your weren't a winner of the bet, you tried your best, made changes and were committed, and makes you a winner in your own right! I'm taking my winnings and getting some workout gear, staying motivated. Wondering if i should do a transformer bet? Take care 💟

Just so you know that if you know you are going to miss your final weigh in you can email them and explain your situation and they will let you weigh in early. But it's only a one time deal. :) An idea for next time

  • Congrats everyone! Bring your winnings on over to https://www.dietbet.com/games/97017 and keep the ball rolling!

    This will be my fourth back to back Kickstarter. Daily motivation, prizes, recipes and eating plans, group coaching, a dedicated Facebook community and LIVE yoga (I'm cohosting with an amazing fitness guru) this Dietbet will rock!

    The theme is Summer vs Winter / USA vs Australia (and we need more US representation!!!!) but anyone from any country can join. The food focus is low carb real food and calorie counting.

    Starts June 1!
