Macronutrients — protein, carbohydrates, and fat — are the three primary categories of nutrients that provide your body with energy. Understanding them is the foundation of intelligent nutrition.
Protein: The Builder
Protein is made of amino acids, the building blocks of muscle, enzymes, and hormones. It's also the most satiating macronutrient — high-protein meals keep you full longer.
How much? 1.6–2.2g per kg of body weight per day for active individuals. Sedentary adults need a minimum of 0.8g/kg.
Best sources: Chicken breast, eggs, Greek yogurt, tofu, lentils, cottage cheese.
Carbohydrates: The Fuel
Carbs are your body's preferred energy source, especially for the brain and high-intensity exercise. They're not the enemy — quality and quantity matter.
How much? Highly individual. Athletes may need 4–7g/kg. Sedentary individuals do well with 2–4g/kg.
Best sources: Oats, sweet potato, rice, fruit, legumes, whole grain bread.
Fat: The Regulator
Dietary fat supports hormone production, brain function, vitamin absorption, and cell membrane integrity. Don't cut it too low.
How much? At minimum 0.5–1g/kg. Most people do best with 20–35% of total calories from fat.
Best sources: Avocado, olive oil, nuts, seeds, fatty fish, eggs.
