What's the Deal with Diet?

I don't know if it's the same for everyone out there, but there's something about work that promotes a very, very poor diet. It's not just the cafeteria that serves up "Fried, Fried and More Fried" on the grill. Even without the farce that calls itself a cafeteria, I eat terribly at work. If we order out (which is in itself a significant problem) I order something hideous like pasta with a cream sauce and I'll even order dessert. Never in a million years would I eat like that at home! If a patient or physician brings in a box of doughnuts, I'll grab at least one. Who does that?! What is the deal?!
