Which nutrient is considered the body's main source of energy?

Carbohydrates are considered the body's main source of energy due to their efficiency in being converted into glucose, which is the primary fuel for cells, particularly during high-intensity exercise and for brain function. When consumed, carbohydrates are broken down into simple sugars like glucose, which can be readily utilized or stored for later use. This process allows for a quick supply of energy, making carbohydrates a preferred source during various physical and metabolic activities.

While fats are also a significant source of energy, especially during prolonged, lower-intensity activities, and proteins can be used for energy, they primarily serve other vital functions such as building and repairing tissues. Minerals, on the other hand, play a crucial role in many physiological processes but do not provide energy. Understanding the role of carbohydrates in energy production is essential for optimizing performance and overall health.
