Body-Mass-Index (BMI)

The Body-Mass-Index (BMI) is a parameter for the assessment of body weight of a person in relation to its body size. However, the index is only a rough guide because it does not capture the physical stature and its different composition of weight from fat and muscles. In addition to the Body-Mass-Index the Waist-to-Height-Ratio (WHtR) is becoming increasingly popular in recent years, because the WHtR is probably the most accurate way to assess the body shape.
