BMI Notes

Factors such as race and athleticism can affect weight status results.

For example, an athlete muscular in build may be classed as being overweight when they're actual weight should be categorized as 'normal'. Despite individual factors, BMI provides a general indication as to whether an individual is overweight.

Body Mass Index is calculated using the BMI formula to find the height to weight ratio of an individual. BMI is then compared to 'weight status' categories.

Calculating BMI before, during and after a weight loss/gain program can be beneficial. To find out more about Body Mass Index visit our Body Mass Index home page.
