Macronutrient (Macro)
Protein, carbohydrate, and fat — the three energy-providing nutrients measured in grams.
Definition
Each macro provides energy: protein 4 kcal/g, carbs 4 kcal/g, fat 9 kcal/g. Macro split varies by goal: cutting (high protein 1.0 g/lb), bulking (high carbs), recomposition (very high protein 1.0-1.2 g/lb). Set protein and fat by bodyweight; let carbs be the calorie remainder.
