What is measuring food energy?Show answer
Food energy is measured in kilojoules (kJ), the metric unit used on Australian food labels. The older unit, the kilocalorie (Calorie), still appears on some products, where one kilocalorie equals about 4.2 kilojoules. Energy values on labels are calculated from the amount of each energy-providing nutrient in a serve. Knowing the per-gram values lets you estimate why one food is far more energy dense than another of the same weight.
What is energy expenditure?Show answer
The body uses energy in three main ways:
What is energy balance?Show answer
Energy balance compares energy intake (kilojoules eaten and drunk) with energy expenditure (kilojoules used) over time.
