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

Well, today was going great until someone asked when I was due. 1) I'm not pregnant and never have been. 2) I'm down 15 lbs this year. How has this just happened? 3) why would someone ask me that?! I really don't have that much of a gut. Needless to say, my morning weigh in with my lowest weight in 2 years was a bit overshadowed. I'm trying to snap out of it though, but what a blow to the self confidence I had this AM.

Aw I'm sorry! That's rough. Perhaps they had pregnancy on the mind and were just projecting. Shift the blame solely to them, it's nothing about you!

So, we can't actually weigh in on Friday? We have to wait until after the 10th?


Correct. Final weigh-ins are 5/11 and 5/12. If you are going to be unavailable to weigh-in those days, email support@dietbet.com and they may allow you to weigh in early.

Weekends are tough! I need to get a game plan for facing all the temptation. What do you all do to avoid overindulging on the weekend?

My dad used to say that same thing, exactly!

I struggle with weekends because that's when friends and family want to go out to eat the most. I found it helps me if I know where we are eating in advance, and then I look at the menu and nutrition online, choose exactly what I'm going to order (pretty much according to the nutrition data), and don't even bother to look at the menu when I get there. It's the pictures that kill me lol - especially when I'm hungry :yum:

Awesome work! That was fast!

It's easier when you have more weight to lose in the first place. But I've been diligent with the calories and exercise.
