Question

Quizplus · Accepted Answer

Carbohydrates provide 4 kilocalories per gram, proteins also provide 4 kilocalories per gram, and fats provide 9 kilocalories per gram. Therefore, the total kilocalories from carbohydrates = 210 grams * 4 kcal/g = 840 kcal, from protein = 60 grams * 4 kcal/g = 240 kcal, and from fat = 52 grams * 9 kcal/g = 468 kcal. The total kilocalories in the meal = 840 + 240 + 468 = 1548 kcal. The percent of kilocalories from carbohydrates = (840 / 1548) * 100 = 54.26%, which rounds to 54%.
