What percentage of total caloric intake should come from carbohydrates?

The recommendation that 55-70% of total caloric intake should come from carbohydrates aligns with the guidelines set by various health organizations, including the Dietary Guidelines for Americans and the World Health Organization. Carbohydrates are a primary source of energy for the body, particularly for athletes and active individuals, as they fuel high-intensity workouts and support endurance activities.

The higher percentage ensures that there are sufficient glycogen stores in muscles, which is essential for maintaining performance during prolonged or intense physical activities. Moreover, carbohydrates have an important role in the recovery process following exercise, helping to replenish glycogen stores and support muscle repair.

While other macronutrients like proteins and fats are also important for a well-rounded diet, the evidence suggests that a higher carbohydrate intake is beneficial for optimal health and athletic performance, particularly for those engaging in significant physical training. Ensuring that the majority of caloric intake comes from carbohydrates can also aid in sustaining energy levels throughout the day and preventing fatigue during workouts.
