It is a complex process and a lot more than just how much energy your body burns.  This video explores some of the key parts of metabolism, including vital nutrients -- such as water, vitamins, minerals, carbs, fats, and proteins -- as well as how anabolic reactions build structures and require energy, while catabolic reactions tear things apart and release energy.   It's from the folks at "Crash Course", who do a great job explaining it all.
