## BMI calculator: am I too fat or too thin?

Beauty is relative and opinions are also divided when it comes to the ideal figure. But there is no arguing about health, because it can be assessed objectively. The BMI helps quite simply: The abbreviation stands for "Body-Mass-Index" and was developed by medical professionals. But you don't have to be a doctor to use the helper.
