Which of the following best describes the recommended percentage of total calories from protein, fat, and carbohydrates for most physically active adults?

The recommended percentage of total calories from protein, fat, and carbohydrates for most physically active adults emphasizes the need for a balanced intake that supports energy levels and muscle recovery. The first choice outlines a macronutrient distribution that aligns well with the established dietary guidelines for athletes and active individuals.

Protein is crucial for muscle repair and recovery, and a range of 10-15% ensures that individuals have enough to meet their needs without over-consuming. Fat is also essential for hormonal function and energy, with 30% being an optimal amount that provides essential fatty acids while allowing space for carbohydrates. Carbohydrates are a vital energy source for those who engage in regular physical activity, and the allocation of 55-65% supports sustained energy levels necessary for performance and recovery.

This distribution reflects a common consensus in sports nutrition, which recognizes that carbohydrates should be the primary source of energy, especially for endurance and high-intensity activities. It balances the need for protein to aid in recovery while still providing sufficient fat intake for overall health.

Other options present macronutrient distributions that may not provide as effective a balance for physically active individuals, leading to less optimal performance and recovery capabilities.
