OK,
Here's some realities. Carbohydrates accompanied by fat are the worst combination and are the source of most obesity. The excess calories over and above your Basil Metabolic Rate, the minimum calories to keep you alive, that are not burned through exercise are stored as fat, aka "Beer Belly", for us guys and big hips/thighs for the ladies.
That is why beer (carbohydrates) and pizza (carbohydrates and fat) are such a fattening combination. Other killer foods that are chock full of carbs and fat are icecream, macaroni and cheese, hamburgers with big buns (no pun intended), and mayonnaise, etc.
I won't get into the science of insulin and glucogon, but will tell you that proteins and fat won't create the same wieghty issues!
