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

Happy New Year! After being a bit too festive during December, it's time to refocus on healthy eating habits and regular exercise. Sign-ups are currently underway for my new Diet Bet, "It's No Sin 2 Be Thin," which starts on Monday, Jan. 6. Those who participated in the games I hosted last year shed 1,756.4 pounds and won $8,425. I personally released 75 lbs and am $1500 richer! Weigh ins start this weekend! Come join us!

My new DB game, "It's No Sin 2 Be Thin," begins on Monday, Jan. 6. I hope many of you will consider joining me in releasing any pounds that might creep up during the holidays. January is going to be a real action-packed game full of renewed vigor and commitment.

Check it out here....

I'm taking a break from Diet Betting during the month of December to focus on maintaining my 75 lb weight loss. I'll only be in the DB10 Beta game during the holidays, which will keep me still going to the gym and eating as healthy as possible. I wish everyone in the US a Happy Thanksgiving!!!! Enjoy yourselves but not too much since we have our weigh in next Monday.

For all of you wanting to know and all those who didn't want to know as well :)

I did it this morning.. weighed in at 89,3 kilos / 196,5 lbs so I reached my personal goal a day late - but I'm happy as can be!

Set a new goal at 86 kilos / 189 lbs - trying to reach that in the january DietBet :)

Final weigh-in: 182.5. Initial weigh-in: 191. Pounds lost; 8.5. Bet won. Thank you everybody!! This totally kept me on track and I wouldn't be at 182.5 without everyone. 4.5 more pounds to reach my final goal. :)

Verified and done. Missing 100 grams for my own goal but that will, hopefully, be gone tomorrow morning.. making it 28,7 kilos in 18 months :)

Congratulations to all us losers who lost weight during this diet bet :) we are lighter, fitter, healthier than when we begun and it's a wonderful feeling and accomplishment ! It was a close call for me, had to up my game and get off salts and added veggie juice over the last few days daily apart from the running to knock it off. Thank you guys for your amazing support! I haven't been able to check in as much as I would have liked but I really enjoyed being on this journey with all of you :)
