Specifically on the bmi thing, I'm curious to hear a practicing physicians argument for measuring and discussing with patients. If I was healthy bmi I wouldn't be able to pick a barbell up. If you but any amount of muscle on your overweight. They might argue to use it for NPC speak. But I wonder if it really is useful in any way compare to any type of body composition testing. That said blood test results return numbers not pass/fail. We can look at them ourselves and compare them and it's always up to the physician to relay them accurately to you. I spend some time recently doing that. I'm not sure what the point of "global" standards are except that I guess MD's can be NPCs as well.
