What Are Macronutrients?
Macronutrients are the three main nutrients your body uses for energy: protein (4 cal/g), carbohydrates (4 cal/g), and fat (9 cal/g). Tracking macros gives you more control over body composition than simply counting calories — high protein preserves muscle during a cut, adequate carbs fuel performance, and healthy fats support hormonal function.
