What is the recommended percentage of total daily calories that should come from carbohydrates?

  1. 20%-30%

  2. 30%-40%

  3. 45%-65%

  4. 70%-80%

The correct answer is: 45%-65%

Carbohydrates are an essential macronutrient and serve as a primary energy source for the body, especially during exercise and physical activity. The recommendations from various nutritional guidelines, including those from the Dietary Guidelines for Americans and the World Health Organization, suggest that carbohydrates should make up 45% to 65% of total daily caloric intake for the average adult. This range allows individuals to consume enough carbohydrates to support energy demands, particularly for those who are active, while still maintaining a balanced diet. Inclusion of carbohydrates at this level ensures that individuals have adequate glycogen stores, which are crucial for sustained physical performance and recovery. Moreover, carbohydrates are important for overall health, digestion, and providing necessary fiber. Maintaining a dietary balance within this recommended range supports not only energy levels but also aids in optimal metabolic function and performance, particularly for those with an active lifestyle or fitness goals. Hence, the response indicating that 45%-65% of total daily calories should come from carbohydrates is aligned with established nutritional recommendations.
