Question

A high protein diet contains 70.0g of carbohydrates, 5.0g of Fat, and 150g of protein. How much energy, in kilocalories, and kilojoules, does each diet provide? Round answers off to tens place

Answer 1

925kcal, 3870.2kJ.

Step-by-step explanation:

The calorie densities of these energy sources are:

Carbohydrates: 4kcal/g

Fat: 9kcal/g

Protein: 4kcal/g

70.0g of carbohydrates are:70.0g * (4kcal/g) = 280kcal

5.0g fat * (9kcal/g) = 45kcal

150g protein * (4kcal/g) = 600kcal

The energy in kilocalories is 600+280+45 = 925kcal

As 1kcal is 4.184kJ. 925kcal are:

925kcal * (4.184kJ/1kcal) = 3870.2kJ
