HOW TO CALCULATE YOUR BODY MASS INDEX - AND WHAT IT MEANS Body mass index (BMI) is a measure of body fat based on your weight in relation to your height. Standard Formula: BMI = (weight in pounds / (height in inches x height in inches)) x 703 Metric Formula: BMI = (weight in kilograms / (height in meters x height in meters)) Measurements: Under 18.5: Underweight

Underweight 18.5 - 24.9: Healthy

Healthy 25 - 29.9: Overweight

Overweight 30 or greater: Obese Advertisement

Experts said a greater number of parks and exercise areas, particularly in poverty-stricken towns, could help.

'We have spent too long as a nation expecting individuals to be able to change their behaviour to reduce their weight,' Professor Rosemary Calder, from the Mitchell Institute health think tank, said.

'However, the evidence is very clear that this has little chance of success without a very strong focus on the environmental factors in the places where we live that contribute to poor nutrition and inactivity.'

Whether someone is a healthy weight, overweight or obese is determined by their Body Mass Index (BMI).

A BMI score is determined by respondents’ height and weight.

Australians living in regional or remote areas were more likely to be fat, with 72 per cent of them in this category compared with 65 per cent of city residents.
