The BMI calculation can be a quick and useful guide when it comes to assessing a healthy weight, as it accounts for many of the natural variations in our body shapes.
GP’s, personal trainers and healthcare professionals will, most likely, assess any results against other considerations during their assessments, as the BMI can be influenced by different factors.
It is well known that muscle weighs more than fat, meaning a muscle dense person – say a bodybuilder or an athlete – can still be considered within a healthy weight range even though their BMI lists them in the overweight or obese category.
Ethnicity also plays a part. People from different parts of the world may have increased risk of certain health conditions within certain ranges. For instance, the healthy BMI range tends to be lower for people of Asian heritage and higher for Polynesians.
