IMPORTANT: No mathematical formula has been found yet to be a definitive predictor of being overweight or underweight. They just serve as indications of statistical risk, but they can be wrong. However, only a physician can diagnose whether someone is overweight, obese, or suffers of any disease. Please consult your physician.
