Understanding Macronutrients

Macronutrients (macros) are the three main nutrients your body needs in large amounts: protein, carbohydrates, and fat. Each plays a unique role.

• Protein (4 cal/g): Builds and repairs muscle, supports immune function, keeps you full.
• Carbohydrates (4 cal/g): Primary energy source for the brain and muscles. Choose complex carbs.
• Fat (9 cal/g): Essential for hormone production, nutrient absorption, and brain health.
