Understanding Macronutrients

Macronutrients are the three primary nutrients your body needs in large amounts: protein, carbohydrates, and fat. Each plays vital roles in your health, performance, and body composition. Understanding how to balance these macros can help you achieve your fitness and health goals more effectively.

Protein

Protein is essential for building and repairing muscle tissue, producing enzymes and hormones, and supporting immune function. Each gram of protein provides 4 calories. Most experts recommend 0.7-1 gram per pound of body weight for active individuals.

Carbohydrates

Carbohydrates are your body's preferred energy source, particularly during high-intensity exercise. They fuel your brain, muscles, and central nervous system. Each gram provides 4 calories. Choose complex carbs from whole grains, fruits, and vegetables for sustained energy.

Fats

Dietary fats are crucial for hormone production, vitamin absorption, cell membrane integrity, and brain health. Each gram provides 9 calories. Focus on healthy fats from sources like avocados, nuts, olive oil, and fatty fish while limiting saturated and trans fats.
