The Body Mass Index is an index used to assess the health risks associated with overweight or thinness.

Because weight alone is not enough to diagnose obesity, overweight or excessive thinness: it is not the same thing as doing 90 kilos if you are 1m50 or 1m 90.

How to calculate the BMI?

The body mass index is calculated by dividing weight by height squared. The World Health Organization has defined this index as the standard for identifying weight problems.

Through studies, thresholds were then established to assess risk areas, including cardiovascular disease.

BMI is a reliable method for adult women and men aged 18 to 65, but cannot be used as-is for pregnant or nursing women, seniors, endurance athletes, or very muscular people.

The interpretation of BMI is done according to the criteria defined by the World Health Organization

BMI (kg/m²)	Interpretation (based on WHO)
16.5 to 18.5	Lean
18.5 to 25	Normal build
25 to 30	Overweight
30 to 35	Moderate obesity
35 to 40	Severe obesity
more than 40	morbid or massive obesity

Interpretation of your BMI

Please note that this classification is still statistical, it does not necessarily apply to all adults, especially athletes or seniors.
