Quizplus · Accepted Answer

The energy content of food can be calculated based on the macronutrient composition: protein and carbohydrates each provide 4 kcal/g, and fat provides 9 kcal/g. Vitamins and water do not provide energy. Therefore, the total energy is calculated as (4g protein * 4 kcal/g) + (10g fat * 9 kcal/g) + (25g carbohydrate * 4 kcal/g) = 16 + 90 + 100 = 206 kcal.
