Food is very important: it's not just here to keep us full, food is also a source of energy. We use energy in our bodies to grow, be active and stay healthy. Energy is measured in kilojoules or calories. For example, 100g of rice is 590kJ (kilojoules) and 129kcal (kilocalories) Note: Kilocalories and calories are the same thing.)
Why do we need energy?
We use energy to carry out everyday jobs such as digestion, movement, breathing and body temperature control. This is why food is so important.
What is BMR?
BMR stands for Basal Metabolic Rate. BMR is the minimum amount of energy your body needs to carry out chemical processes while at rest.
Who needs energy?
Different people need different amounts of energy. Depending on their age, health, job and body size, people need different daily calorie intakes.
Energy Balance
It is important to only eat what you need. If your intake is greater than your output of energy, you may become overweight because all the fat is stored in your body. However, if your intake is less than your output, you will loose weight. It is important to balance it out.
Energy Density
Energy density is the amount of calories per bite.
