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

Hi Everyone!

I hope you are doing great maintaining your healthier habits. I just wanted to remind everyone that if you won a prize throughout the Bet...... PLEASE message me your full name, email, and address-the way it would appear on an envelope

I will give everyone 2 weeks from end of bet, so until DECEMBER 7TH to send me your info. If I don't receive your information I will consider your prize forfeited. I send all prizes out at the same time, in case you are looking for yours. ;)

I've sent my information previously. Do you need it again?

Should we still be waiting to receive it?

Sorry ladies! Dietbet encourages healthier weight loss, which the only way they can try to regulate that is to put a maximum weight loss within the 4 weeks. If you loss more than 12% of your body weight then I say Congratulations! Unfortunately, they state it in the rules. I actually just realized this because of the Transformer Bet I'm hosting there they put limits on weight loss each month to pace the weight loss. If you didn't lose more than 12% check with customer service because something might have been entered wrong.

I had lost 2 extra pounds and it said I didn't win. Which would have been about 5%. I emailed them and they said they had entered numbers wrong.

I had a friend pass suddenly from lupus this week. I ended up over eating and totally screwed my weight. Oh well, I'll try again sometime.
