Dietary changes that support better athletic performance include consuming a balanced diet rich in complex carbohydrates, lean proteins, and healthy fats. Carbohydrates are the primary fuel source for athletes, providing the energy needed for intense training and competitions. Adequate protein intake is vital for muscle repair and recovery post-exercise. Additionally, staying hydrated is critical for optimal performance. Incorporating a variety of whole foods, such as fruits, vegetables, and whole grains, ensures the body gets essential vitamins and minerals that support overall function and health.
