Compare the determined value which corresponds to those being used by the WHO
BMI below 18,5
 The patient is under the regular standard and does not got enough weight An increase of
weight is recommended Please consult a professional
BMI between 18,5 and 24,9

BMI between 25 and 30
 The patient is slightly overweighed to pre-obese A reduction of weight is indicated or, is
necessary if the state of health is already affected (e g diabetes, high end blood pressure,
heart diseases)
BMI over 30
 Reduction of weight is imperative To visit a doctor is highly recommended
