Learn The Secret Of BMI Calculations

BMI is the ratio of body weight to height, due to which a person is determined to have insufficient, normal or excess body weight.

Sometimes the calculation of BMI gives not entirely correct results. The fact is that it is important to remember that the ratio of fat and muscle tissue in people is different and depends on many factors. Therefore, people with the same BMI do not look the same.
