 What is the body mass index?

The body mass index is a measure commonly used to determine overweight.

The definition by the WHO of a healthy weight is a BMI between 18.5 and 24.5.
A BMI over 25 kg/m2 is defined as overweight and a BMI of over 30 as obese while a BMI of 16 defines severe thinness. Both conditions, severe thinness and severe obesity are live threatening conditions.
