What are calories?

Calories are a measure of how much energy food or drink contains.

Calories and kilocalories

The term calorie is commonly used as shorthand for kilocalorie. You will find this written as kcal on food packets.

Kilojoules (kJ) are the equivalent of kilocalories within the International System of Units, and you'll see both kJ and kcal on nutrition labels. 4.2kJ is equivalent to approximately 1kcal.

How many calories do I need?

The amount of energy you need will depend on:

  • your age – for example, growing children and teenagers may need more energy
  • your lifestyle – for example, how active you are
  • your size – your height and weight can affect how quickly you use energy

Other factors can also affect how much energy you burn. For example:

  • some hormones (chemicals produced by the body) – such as thyroid hormones
  • some medicines – such as glucocorticoids, a type of steroid used to treat inflammation
  • being unwell

Maintaining a healthy weight

To find out if you are a healthy weight, use the BMI calculator.

To maintain a healthy weight, you need to balance the amount of calories you consume through food and drink with the amount of calories you burn through physical activity.

Losing weight

To lose weight in a healthy way, you need to use more energy than you consume by eating a healthy, balanced diet with fewer calories while increasing your physical activity.

A GP can also give you advice about losing weight.

Gaining weight

You should get advice from the GP if you're underweight (your body mass index is less than 18.5).

To gain weight, you need to eat more calories than your body uses each day. For more information, see How can I gain weight safely?.
