body fat
I am seeing all sorts of problems with coming up with accurate body fat. Hence let me ask a bunch of questions:
Is it important, or at least useful to know your body fat?
Callipers, I have read that these are grossly inaccurate, and that the best practiioners, unconsciously look at the person, and measure until they get the results they 'know' are accurate (?)
Electronics, not particularly accurate, closeness to meals, time of exercise, other factors make a big difference (?)
The so called Gold Standard, hydrostatic testing. the best web sight on this, is by a physics professor at the University of Chicago, Accurate and easy body fat determination, (this should bring it up on google). However his charts show that you have less the 10% body fat if you sink with a full exhalation. I sink with a 70% deep inhalation. But given my belly I really think I am closer to 15% than 8%. Also if you are black or athletic your fat % can be higher. I suspect most of us who lift weights are 'athletic'.
So.... I track my buoyancy, and try to keep it neutral at 2/3 to3/4 deep inhalation. That does give me an accurate relative reading, but I have not idea, really, of what my body fat really is.
I suspect that using any of the above methods at regular times of day, per meals, exercise et cetera will give you an accurate relative reading. Rob
