Calories in vs. calories out has more to do with body mass than body composition. Body composition is more of a subsequent effect of the total calories you take in. Calories are a measurement of energy so even with food the law of conservation of energy and mass applies. So to lose weight, you either have to excrete mass(poop, pee, splooge, etc) or burn it as energy. Of course the Calories listed on the food label doesn't always translate(digest) into energy your body utilizes and certain calories will get utilized different ways.
