A balanced diet concerning macronutrients involves a proper ratio of carbohydrates, proteins, and fats. Each macronutrient plays a critical role: carbohydrates provide energy, proteins support muscle repair and growth, and fats are crucial for hormone production and nutrient absorption. Typically, a balanced diet might consist of 45-65% of daily calories from carbohydrates, 10-35% from protein, and 20-35% from fats. Striking this balance is vital for maintaining energy levels, supporting bodily functions, and achieving overall wellness.
