Personally I believe that colas are a leading factor in the obesity crisis, it's about the worse thing you can consume. It's right up there with cigarettes in my mind. So there is no doubt in my mind about the evils of cola.

But I was thinking that if you are having a 800 calorie meal (or whatever a BigMac and fries is these days), wether you add a real coke or diet coke isn't going to make much of a difference.

Now if you are going to have a BigMac and fries everyday, well real Coke vs Diet Coke might make a difference, I don't know. Thinking about the effect of eating that much junk food is just too scary to contemplate.
