Question

Quizplus · Accepted Answer

The meal contains 1120 kcal in total. Carbohydrates account for 48% of the energy, and protein accounts for 13%. To find the calories from fat, we first calculate the calories from carbohydrates and protein, then subtract these from the total calories. Carbohydrates: 1120 kcal * 48% = 537.6 kcal. Protein: 1120 kcal * 13% = 145.6 kcal. Calories from fat = Total calories - (Calories from carbohydrates + Calories from protein) = 1120 kcal - (537.6 kcal + 145.6 kcal) = 1120 kcal - 683.2 kcal = 436.8 kcal, which rounds to 437 kcal.
