Carbohydrates, lipids, proteins: the three energy pillars of nutrition.
Macronutrients are nutrients the body needs in large amounts: carbohydrates, lipids, and proteins. They provide energy and cellular building materials.
Each macronutrient plays a distinct and irreplaceable role. Carbohydrates provide rapid energy, especially for the brain. Lipids form cell membranes and transport fat-soluble vitamins. Proteins build and repair tissues. A balanced meal integrates all three in appropriate proportions.
Provide energy and building materials to all cells.
Target 50-55% carbohydrates, 30-35% lipids, 10-15% proteins of total energy intake.
Without sufficient macronutrients, the body can neither produce energy nor regenerate.
