A healthy balance of macronutrients for athletes generally consists of approximately 55-65% carbohydrates, 15-20% protein, and 20-30% fats. This ratio helps support intense training and muscle recovery. Carbohydrates are crucial for maintaining energy levels, while protein aids in repairing and building muscle tissues. Healthy fats are also important for overall health and energy. Athletes must adjust these ratios based on their specific sport, body composition goals, and workout intensity to optimize performance and recovery effectively.
