Doctors and health experts use different measures to determine if adults are at a healthy weight.
The first is the body mass index (BMI). BMI was designed to assess weight-related health risks in the general population, meaning everyday Aussies.
A BMI over 25 is considered overweight, while a BMI over 30 is considered obese. BMI varies by ethnicity; for example, those of Asian descent are considered overweight at a BMI of 23.
The 60-second Weight Check on this website is customised to your ethnicity, so you can get feedback on whether your weight is considered healthy based on your heritage.
We use BMI because it is a simple and easily available measurement - all you need is your height and weight. Other measurements, like body fat percentage, are more accurate but also requires the assistance of a health professional which means far fewer people can take part in Weight Check 2017.
BMI is not a good measure for elite athletes, those who are very lean, pregnant women and the elderly. It’s common for this group of people to have an “overweight” BMI despite being perfectly healthy.
Waist measurement is the other tool doctors use to determine if your weight is healthy.
A waist measurement greater than 80cm in women and 94cm in men is associated with a higher risk of weight-related diseases, such as heart disease and type 2 diabetes.
These measures vary by ethnicity. For men, a good rule of thumb is: if the circumference of your waist is greater than your hips, it’s time to visit the doctor for a check-up.
