BMI

The body mass index (BMI) is an indicator that evaluates a humans body weight in relation to his size. The BMI does not take aspects into account, that seem relevant for a generally applicable formula, since body traits such as stature, sex or the proportion of fat and muscle tissue naturally vary for each human being. Critics therefore say that its scientific relevance is questionable. Interesting fact: Studies show that people who are in a relationship, often have a higher BMI than singles.
