A balanced macronutrient ratio for fitness typically consists of approximately 40-60% carbohydrates, 20-35% fats, and 10-35% protein, depending on individual energy needs and fitness goals. This ratio supports optimal energy levels for exercise while ensuring adequate nutrient intake for recovery and muscle growth. For endurance athletes, a higher carbohydrate ratio may be beneficial, whereas strength-focused individuals might prioritize protein intake for muscle repair. Overall, a well-rounded diet with appropriate macronutrient distribution is essential to achieve fitness goals and maintain health.
