I don't think our bodies process calories and macronutrients the way some of you guys describe. The whole "extra carbs = fat" and such argument is silly. It's not as if your body gets all its calories for the day, calls it "done", and then you add 50g of pure carbs and it just stores them as fat. Our bodies are in a constant state of energy consumption. The only time this process stops is when you die. This energy comes from all kinds of different sources and macronutrients. If, on average, the body finds that it has more energy than it needs, it stores it for later, if it has less than it needs, it starts burning through its reserves.
