To balance macronutrients effectively for optimal energy, one should tailor their intake of carbohydrates, proteins, and fats to match their specific activity level and goals. A common guideline is to consume 45-65% of daily calories from carbohydrates, 10-35% from protein, and 20-35% from fats. This ratio supports sustained energy levels and muscle repair. For example, athletes typically require a higher protein intake for muscle recovery. Regular monitoring and adjusting of these ratios can help maintain energy, promote overall health, and optimize performance.
