A balanced diet significantly contributes to physical performance by providing the necessary nutrients to fuel workouts and support recovery. Essential macronutrients, including carbohydrates, proteins, and fats, play distinct roles in energy production and muscle repair. Carbohydrates serve as the primary energy source, while proteins aid in muscle recovery and growth. Incorporating a variety of vitamins and minerals ensures optimal metabolic function and immune health. A well-rounded diet, therefore, helps individuals maintain energy levels, enhances workout performance, and promotes overall health and fitness.
