Considered one of Hollywood's scary skinny elite, Victoria Beckham doesn't seem to have any trouble keeping the pounds off. Is it because she avoids carbs? The fashionista did admit that she doesn't eat Italy's national dish -- which is unfortunate seeing as she's moving to Milan this year.

Nope, that's not it at all -- she physically can't eat it, according to FemaleFirst.co.uk. "It's not that I avoid carbs, I'm allergic to pasta. It's like my kryptonite. I feel like I can't digest it properly and it makes me feel ill," she says.

Pasta is my kryptonite too. I have this unfortunate condition in which I eat tons of it because I love it, and then my hips get wider and I can't fit into my jeans. Oh, wait. That's not really an allergy I guess.

What's your kryptonite?
