BigBallBellyGirl:
I remember reading somewhere the biggest belly ever measured was 120 inches, and I used to think I wanted to achieve that. Currently -- I'm around 93 inches standing, and I'm dealing with a good bit of back pain, because I carry a lot of visceral fat. I don't really think my body could handle a bigger belly. It's still fun to fantasize though about being 10 ft around!
The Guiness book's section on heaviest humans had a note for someone (I forget who) saying that he won a Reader's Digest contest for "biggest belly". Maybe that was it.
