See my point about having a disease...
I don't know anyone else who can eat like that and stay at 150lbs. I eat a similar amount of calories and maintain my weight, but i'm 230lbs and 6' 3".
I'm not saying your lieing or anything, i'm sure you're not, but it's extremely unusual.
Either way, whether it is making you fat or not, eating like that is wholly unhealthy and it's still going to significantly reduce your health span. But then you're not stupid and i'm sure you know that. I eat terrible too knowing how bad it is, but whatever, I don't care. Far more likely to fall off my bike and die before any eating related disease gets me lol.
On that topic, off to domino's to pick up a large pizza
