BMI is truly shit. Let me tell you an anecdote. While at Uni I was a semi professional MTB DH racer. I am 188cm tall and weighted 88kg when in best shape of my life - I weigh a lot since my build is super robust (I had <10% body fat at that point) and I do have big bones :) (really you should see my wrists). In December, that means off season for me (athletes tend to pick up some weight during that period), we had an physical exam for Uni - I weighted 94kg at that point. So at the end of all the tests I walk into the doctors office, who while peering into my file commands me to take off my shirt and sit down. She proceeds to comment the results along the lines of: "... everything is perfect, but you are overweight (BMI 26.6) - you absolutely have to loose some weight!" At this time she rises her eyes from the file and looks at me sitting in front of her, top naked. Blushes and says: " but only a kilo or two!". BMI may work for average. But the sad fact is that people are rarely average. And as others have noted, recent findings indicate that some level of body fat - protects from diabetes and other diseases. Meaning that nutrition is not really that simple.
