What macros actually mean
Macros are the three main nutrients that make up your calories and help shape your results.
Protein
Supports muscle retention, recovery, fullness, and body composition. It is usually the most important macro to lock in first.
Carbs
Your main source of quick energy. Carbs help support training, performance, and day-to-day energy.
Fat
Supports hormones, health, and satiety. You need enough fat, but not so much that it crowds out your other targets.
Why calculate macros instead of just calories?
Calories tell you how much you are eating. Macros help tell you what your calories are made of. Two diets with the same calories can feel very different depending on protein, carbs, and fat. That is why macro targets are often more useful than calories alone.
