Why your Body Mass Index is important.

BMI stands for Body Mass Index and is calculated by dividing your weight, in kilograms, by your height, in metres squared. BMI is a useful tool to estimate whether you are underweight, overweight or at a healthy weight in relation to your height. As your weight increases or decreases out of the healthy weight range, it can increase your risk of health problems.

Use our easy BMI tool to get started!

Do be mindful that it is an estimate and does have some limitations as it does not take into account factors such as age, gender, ethnicity and body composition. It is also not accurate for children and pregnant women.


Enter your height and weight to calculate your body mass index (BMI) and assess your health risk.

Your BMI is...




A BMI of falls into the underweight range.

This may put you at risk of health issues and you may wish to consider increasing your weight to within the healthy weight range. For individualised advice we recommend that you visit your general practitioner or an Accredited Practising Dietitian (www.daa.asn.au).


A BMI of falls into the healthy range.

The healthy range represents the lowest level of risk for heart disease, diabetes and hypertension. To further reduce your risk, focus on healthy eating including foods such as fruits, vegetables and whole grains, as well as staying active for life.


A BMI of falls into the overweight range.

This means you may have an increased risk for health problems such as heart disease, diabetes and hypertension. The good news is that through healthy eating and regular physical activity, you may be able to reduce your weight and lower your disease risk.


A BMI of falls into the obese range.

This further increases your risk for health problems such as heart disease, diabetes and hypertension. The good news is that by losing as little as 5-10% of your current weight, you may be able to reduce your risk of some of these conditions. A combination of healthy eating, an active lifestyle, and one-on-one support may help you to move towards your weight loss goal.
