What is the prescribed macronutrient split in the CrossFit dietary prescription?

• A. Protein 30%, Carbohydrates 40%, Fat 30%
• B. Protein 40%, Carbohydrates 30%, Fat 30%
• C. Protein 25%, Carbohydrates 50%, Fat 25%
• D. Protein 20%, Carbohydrates 60%, Fat 20%

Answer: (A)

The main idea is that the CrossFit dietary prescription uses a Zone-like macro balance: roughly 40% of calories from carbohydrates, 30% from protein, and 30% from fat. This distribution places carbs as the primary fuel to support high-intensity training, while protein supports muscle repair and fat provides steady energy and essential fats. The option that lists protein at 30%, carbohydrates at 40%, and fat at 30% matches this balance, reflecting the recommended emphasis on carbs with equal moderate protein and fat. This aligns with fueling performance and recovery for intense workouts. Other splits would shift the emphasis away from this carb-forward pattern, making them less consistent with the CrossFit recommendation.
