Evaluating Body Mass Index for adults:
Compare the value determined with the categories quoted below which correspond to
those used by WHO, 2000.
• BMI below 18.5:
Warning, this patient weighs too little. There could be a tendency to anorexia. An in-
crease in weight is recommended to improve well-being and performance. If in doubt,
consult a specialist.
• BMI between 18.5 and 24.9:
The patient is of a normal weight. He can stay as he his.
• BMI between 25 and 30 (pre-obese):
The patient is slightly to moderately overweight. He should cut his weight if he is already
ill (e.g. diabetes, hypertension, gout, fat metabolism disorders).
• BMI over 30:
Weight reduction is essential. Metabolism, cardiovascular system and bones are all un-
der strain. A consistent diet, plenty of movement and behavioural training are all rec-
ommended. If in doubt, consult a specialist.
