A balanced macronutrient distribution for an athlete typically includes approximately 45-65% carbohydrates, 20-35% fats, and 10-35% proteins. Carbohydrates are essential for providing energy, particularly for high-intensity activities. Proteins aid in muscle repair and growth, while healthy fats support overall health and hormone production. Individual needs may vary based on the sport and personal goals; endurance athletes may require more carbs, while strength athletes might focus on protein intake. Tailoring the distribution to specific training regimens can optimize performance.
