Answer 2

Answer:

Energy is measured in units of kilocalories (kcal) or kilojoules (kJ). One kilocalorie (1 kcal) is equal to 4.18 kilojoules (4.18 kJ). The amount of energy a food contains per gram is known as its energy density so we can describe fat as more energy dense than protein or carbohydrate.
