Frequently Asked Questions
Is BMI accurate for all Australians?
BMI is a screening tool, not a definitive health measure. It doesn't distinguish between muscle and fat mass — a very muscular person may have a high BMI but excellent metabolic health. BMI also doesn't indicate fat distribution, which is important for disease risk. For people of Asian background, risks may be elevated at lower BMI values. Use BMI as one indicator among several.
What is a healthy weight for my height in Australia?
The healthy BMI range of 18.5–24.9 corresponds to specific weight ranges for each height. For example: 165cm = 50.3–67.8kg healthy range; 175cm = 56.6–76.3kg; 185cm = 63.3–85.3kg. These ranges are the same regardless of age (for adults) or sex.
How does BMI relate to life expectancy?
Australian and international research consistently shows that both BMI below 18.5 and above 30 are associated with increased mortality risk. The relationship is complex — BMI in the range of 20–25 is generally associated with the lowest risk of premature death in Australian population studies. However, fitness level, smoking status and other factors often matter more than BMI alone.
Can I have a healthy BMI but still be unhealthy?
Yes — this is sometimes called 'metabolically obese, normal weight' (MONW). A person with a healthy BMI but high body fat percentage (especially abdominal fat) and low muscle mass can still have elevated cardiovascular and metabolic risk. This is why waist circumference measurement alongside BMI is recommended by Australian health guidelines.
