Approximately what portion of daily energy calories is supplied by carbohydrates?

Carbohydrates are an essential macronutrient that provides energy to the body. They are typically the primary source of energy for many individuals, contributing significantly to the overall caloric intake.

In a balanced diet, it is generally recommended that around 45-65% of total daily calories come from carbohydrates. This recommendation supports energy needs, particularly for high-intensity activities and is essential for the proper functioning of the brain and central nervous system.

The answer indicating that two-thirds of daily energy calories is supplied by carbohydrates aligns with the higher end of this recommended range. It accounts for the energy demands of an active lifestyle and recognizes the role of carbohydrates in providing fuel for physical and mental activities. The other options suggesting one-third or half do not align with the general dietary guidelines that advocate for a higher carbohydrate intake for optimal energy levels.
