What is a macronutrient ratio for a balanced diet?

The macronutrient ratio of approximately 45-65% carbohydrates, 10-35% protein, and 20-35% fats is widely accepted as a guideline for a balanced diet. This range is supported by various dietary guidelines and nutritional organizations, which emphasize the importance of carbohydrates as the body's primary source of energy. Carbohydrates are vital for fueling physical activity and maintaining overall health, so a higher percentage within the specified range aids in supporting these functions.

Protein plays a crucial role in body maintenance and repair, and the recommended range acknowledges its importance while allowing flexibility according to individual needs, such as those for athletes compared to sedentary individuals. Fats are essential for hormone production and nutrient absorption, and the specified range ensures that enough is included in the diet without contributing excessively to calorie consumption.

This balance allows individuals to obtain the necessary nutrients to support a healthy lifestyle, accommodate physical activity, and promote overall well-being. Therefore, this option represents a balanced approach to macronutrient consumption consistent with nutritional science.
