Random Friday question

When I'm stressed, I completely lose my appetite.  I don't remember to eat; I don't want to eat; and when I do eat, the food doesn't taste good, even though I can't point to any objective difference from the way it normally tastes.

A substantial minority of people I know are like this; the rest tend to want to dive into the cookie dough ice cream.  So, discuss.  Are you a stress eater or a stress anorexic?  And does anyone have any idea why the difference might have evolved?
