An athlete's optimal diet should consist of what approximate percentages of protein, fat, and carbohydrates?

  1. 10% to 20%, 30% to 40%, 50% to 70%

  2. 25% to 35%, 55% to 65%, 70% to 90%

  3. 12% to 15%, 40% to 50%, 55% to 70%

  4. 45% to 55%, 10% to 20%, 45% to 55%

The correct answer is: 12% to 15%, 40% to 50%, 55% to 70%

The optimal diet for an athlete generally aligns with the recommended macronutrient distribution that supports their energy needs, recovery, and overall performance. For many athletes, a diet might consist of approximately 12% to 15% of calories from protein, which is essential for muscle repair and recovery, while fat should make up about 40% to 50% of total intake, serving as a source of energy and essential fatty acids. Carbohydrates, which are crucial for fueling high-intensity exercise, would represent the remaining 55% to 70% of the diet, supporting glycogen stores and providing readily available energy during both training and competition. This combination emphasizes a balance that can help sustain energy levels during prolonged exercise while also emphasizing recovery through adequate protein intake. Understanding the role of each macronutrient can help athletes optimize their performance and overall health.
