You're greatly oversimplifying, which might help you but it encourages ignorance of macros and how differently they're metabolized. It's well known among performance athletes that the body adapts to types of macros. Ultra marathon runners have their bodies adapt to consuming dense caloric foods (fats), as one really obvious example. Professional sports teams employ nutritionists and it's not because they need help counting calories in, calories out. I've spent a lot of time experimenting on myself, I can eat lower calories but if those lower calories are bread and sugary crap, I don't get leaner, I get fatter and weaker.
