Body Mass Index

Body mass index is calculated by dividing your weight (in kilograms) by your height (in meters) squared,


Calculating out your body mass index (BMI) is a quick way to figure out if your weight is healthy for your height. The higher your BMI, the greater the risk of developing health problems. This does not apply to children, pregnant or lactating women.

What are calories/kilocalories?

In nutritional terms, calories and energy are the same thing. A calorie is a unit of energy and the amount of calories in a food is a measure of how much potential energy the food contains:

1 kilocalorie (kcal) = 4.18 kilojoules (kJ)

1000 calories = 1 kilocalorie
