What is BMI?

BMI (Body Mass Index) is a general measurement used to determine whether a person is at an ideal weight for their height. BMI measurements are divided into ranges that specify in general terms whether a person is underweight, ideal, overweight, or obese. These ranges are as follows:

BMI 0 – 18.5 Underweight
BMI 18.6 - 24.9 Healthy Range
BMI 25.0 - 29.9 Overweight
BMI 30+ Obese

How is BMI Calculated?

BMI is an estimation of a person’s total amount of body fat and is calculated by dividing their weight in kilograms by their height in metres squared (m2). It’s important to note that there are some limitations that can influence this including age, gender and ethnicity.

Healthy Weight Range Calculator

What is considered a 'healthy' weight range?

A healthy weight range is determined by a person’s ratio of body mass, depending on their height. Generally speaking, the lower the ratio of body fat, the more healthy a person’s weight range will be. This is a general guide, but can be used as a starting point for setting healthy weight loss goals.

Underweight people are considered to have too little body fat, whereas people of an ideal weight have a healthy amount of body fat that is unlikely to cause them health issues. Overweight and obese people have an excess of body fat. The more body fat a person has, the more at risk they are for health problems such as heart disease, diabetes, and cancer.

Calories & Kilojoules Converter

What’s the difference between calories and Kilojoules?

People eat food to fuel their bodies and the energy that is gained from food can be measured. In Australia, the amount of energy in food and drink is measured in Kilojoules (kJ) which is part of the metric system. Not all countries are on this system, so it's often useful to convert back to calories (cal) and vice versa.

When a person consumes more energy than their body burns, the excess energy is converted into fat and stored in the body. Conversely, when a person expends more energy than they eat, their body burns excess stores of fat and this is how they lose weight.
