The selected answer highlights the optimal post-exercise nutrient combination that is effective for recovery, specifically 20 grams of protein and 60 grams of carbohydrates. This balance is widely supported by research in the field of sports nutrition, as it provides a sufficient amount of protein to aid in muscle repair and synthesis alongside carbohydrates to replenish glycogen stores that are depleted during exercise.

Protein is essential after exercise because it provides the necessary amino acids for muscle recovery and rebuilding, and 20 grams is generally recognized as an effective dose for stimulating muscle protein synthesis. Additional carbohydrates play a critical role, as they not only replace glycogen but also assist in the recovery process when consumed alongside protein due to the insulin response, which facilitates greater nutrient uptake by muscle cells.

The other combinations may not be as effective depending on the context of the workout and the individual's specific needs. For example, a combination with a higher protein content might not take full advantage of the glycogen replenishment potential necessary after intense workouts, while options with inadequate carbohydrates could fail to optimally restore energy levels. Through this lens, the balanced option of 20 grams of protein with 60 grams of carbohydrates provides an evidentially supported approach to successful post-exercise recovery, addressing the biological needs of the body effectively
