How's this for a nutrition pyramid?! On a serious note, the ever burning question; What's the difference between calories and macros? The following advice is largely based off the nutrition pyramid concept developed by Eric Helms.
Energy Balance. Also known as "calories in vs calories out", if that doesn't quite ring a bell then this refers to the amount of calories you consume from food/drink versus the calories you burn from simply being alive, as well as calories burned through both, exercise activity and non exercise activity. This concept is directly responsible for manipulating your WEIGHT (and not necessarily your body composition).
Context: You could get your calories from anywhere. They could come completely from carbs for instance, they could come from entirely processed foods that are deficient in micronutrients. You could also perform copious amounts of cardio to manipulate your energy balance. Conclusively, this may seem to "work" but may not be optimal for body (re)composition.
Evidently, consuming a specific amount of protein for muscle repair/growth, carbohydrates for glycogen replenishment and transport of amino acids to your muscle, as well as fats to maintain hormonal balance, will directly manipulate your body's composition (in reference to fat tissue and muscle tissue specifically).
Therefore, tracking your macronutrients will by default, track your calories as well as prove to be more beneficial in direct respect toward body (re)composition. It does however, take more concious effort to implement, when all factors are considered.
