Quizplus · Accepted Answer

Carbohydrates provide 4 kcal/gram, proteins provide 4 kcal/gram, and fats provide 9 kcal/gram. The total kilocalories from carbohydrates is 210g * 4 kcal/g = 840 kcal. The total kilocalories from protein is 60g * 4 kcal/g = 240 kcal. The total kilocalories from fat is 52g * 9 kcal/g = 468 kcal. The total kilocalories in the meal is 840 + 240 + 468 = 1548 kcal. The percentage of kilocalories from carbohydrates is (840/1548) * 100% ≈ 54%.
