What is the primary role of carbohydrates in the body?

The primary role of carbohydrates in the body is to store energy. Carbohydrates are one of the main macronutrients and are primarily utilized as a quick and readily available source of energy for bodily functions. Once consumed, carbohydrates are broken down into glucose, which can be used immediately for energy or stored in the liver and muscles as glycogen for later use. This stored glycogen can then be converted back into glucose when the body needs energy, especially during physical activities or periods of fasting.

While other macronutrients like proteins are vital for building and repairing tissues and fats serve various functions including insulation, carbohydrates specifically excel in energy provision. This makes them crucial for high-energy activities and overall metabolism.
