When you keep track of your food energy, you can count by the calory or by the 'kilojoule'.

The incorrect word in the student's sentence is "kilojoule." In nutrition, food energy is typically expressed in kilocalories, commonly known as "calories." Therefore, the correct version should refer to "calorie intake" instead of "kilojoule intake."
