Macronutrients are the nutrients your body needs in large amounts: protein, carbohydrate, and fat. Alcohol also supplies calories but is not a nutrient. Each macro carries a set calorie value per gram: protein 4 kcal/g, carbohydrate 4 kcal/g, and fat 9 kcal/g. These values are the basis of every nutrition label. A balanced plate typically pairs a protein source, high-fiber carbs, and healthy fats. The exact split depends on your goals, but all three play a role in satiety, energy, and health.
Key facts:
- Protein: 4 kcal per gram
- Carbohydrate: 4 kcal per gram
- Fat: 9 kcal per gram
- Fiber (a carb) aids fullness and digestion
