What percentage of daily calories should come from carbohydrates for active adults?

1. 20-30%

2. 30-40%

3. 45-65%

4. 55-75%

The correct answer is: 45-65%

Active adults typically require a higher percentage of daily calories from carbohydrates to support their energy levels and physical performance. The recommendation of 45-65% of total daily calorie intake from carbohydrates aligns with guidelines from health organizations, which emphasize the importance of carbohydrates as the body's preferred source of energy, especially during exercise. Carbohydrates play a crucial role in replenishing glycogen stores, which are tapped into during physical activity. Consuming an adequate amount of carbohydrates also helps maintain stable blood sugar levels, contributes to recovery after workouts, and supports ongoing training regimens. This range allows for flexibility based on individual activity levels and metabolic needs, making it suitable for a variety of active adults, from those engaging in moderate daily exercise to those participating in more intense training. In contrast, the other percentages provided may not sufficiently support the energy demands of active individuals. Lower percentages may lead to inadequate energy availability for workouts, diminished performance, and challenges in muscle recovery. Therefore, the recommendation of 45-65% is particularly appropriate for those maintaining an active lifestyle.
