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

Made this DietBet with an extra pound lost to boot! Congratulations to all that made it and those that didn't still be positive that you lost weight! Any loss is a gain!

Cut out soda and late night snacks...who knew that alone was around 500 calories a day! Love my fitbit for keeping me accountable all month! <3 <3

Final weigh in verified! My first ever diet bet was a success! Excited for more challenges! No way did I think I could lose over 10 pounds in one month!

Worked out the past 4 days and made my goal. Feeling good. It definitely was not easy though. Now I can enjoy today and tomorrow's festivities.

Met my goal!!! 😎 I'm not much for exercising, so I forced myself to do it!!! There is a drinking well a mile away from my house with 25 cents a gallon. If I wanted water, I had to walk 2 miles to get it! Also I switched to Keto eating habits and found out I'm not lactose intolerant!!!

Great attitude though. When I lost a dietbet, i was so focused on not making the weight, I forgot to celebrate that I had actually lost 5lbs. So good job and hopefully a reminder to anyone who didn't win the bet, celebrate wining the loss....if you get what I Good job Sharla

Need help resubmitting my weight. I accidentally pushed the submit button before I was able to put in my new current weight. So it now says I lost 0 pounds when I have lost 11.6 pounds and reached my 4% goal. How do I fix this?

It said on mine resubmit under it. I made the same mistake.

I contacted support and they had to reset my account so I could resubmit. Thanks!
