The BMI is what it is. It does not take into account your fat to muscle ratio. This means it is a guide to the average body weights. Obviously you have to take into account your muscle mass etc when you use the BMI as a guide. I challenge your doctor to tell a heavyweight boxer he is morbidly obese and survive more than 5 mins. Really as a medical indicator, the BMI should only (IMHO) be used in conjunction with other measures such as the skin fold tests etc.
Some doctors however seem singularly unable to account for these types of things (like one of my previous doctors, who on my first presentation to her for a pap smear, decided, whilst I was lying half naked on her table, to take my blood pressure (BP). She was, for some unfathomable reason, highly surprised that my BP was through the roof and demanded I take weekly BP measurements for 2 months before she would accede to my insistence that I did NOT need BP medication)
My advice- use common sense. Use the BMI as a guide, taking into account it's weaknesses and augmenting it's result with other information you may have such as skin fold tests, the way you look, trusted friend's assessments etc.
35kg lost. (November 2005 - October 2006)
15kg gained again (as at October 2010).
