Obesity is more than just being a bit overweight. When doctors talk about being obese, they mean that a person has put on so much weight they can start to seriously jeopardise their health. Being overweight can lead to obesity and the start of life-threatening health problems.

Obesity is measured by the body mass index (BMI). The BMI reflects a person’s weight in comparison to their height (weight [kg] ÷ height2 [m2])3. To find out your BMI, please enter your height and weight details into the BMI Calculator below.
How common is obesity?
Obesity has reached epidemic proportions in Australia. Statistics prepared by the Australian Bureau of Statistics (ABS) show that: 61.4% of people aged 18 years or over are overweight (BMI 25.00-29.99) or obese (BMI 30+). Only 36.6% of Australians are considered of ‘normal’ weight (BMI 18.50-24.99) and 2% of people are actually underweight (BMI 18.5 and under).
Many people don't think they are obese...
In a recent market research survey: 3% of the extremely obese (BMI 40+) thought their weight was acceptable. Only 62% of people with a BMI of 40+ accepted that they were obese.
What is Body Mass Index (BMI)?
Body Mass Index (BMI) is a simple measure of a person’s weight relative to their height, which is used to categorise underweight, overweight, obesity and healthy weight in adults. The BMI calculator gives you a quick, clear indication of your ideal weight range by dividing your weight in kg by height in metres; the results help you determine whether you should be taking action toward a healthier lifestyle. To find out your BMI, please enter your height and weight details into the BMI Calculator at the bottom of this page.
