you know that, if you fast for 14 hours, not only will you pass out, but you will also lose 5-15% of your LBM. seriously, i read it somewhere on the net, and thus i know it's true.
hey medical people, the fasting is to stabilize blood lipid profiles without acute dietary influence, correct? anyhoo, does it really take that long? what about coffee and other non-caloric drinks? also, HOW much can eating affect the test? are we talking 20% error or an order of magnitude?
why are you getting these tests? the reason i ask is: will you do anything differently based on the results? if you eat well, exercise hard, and are generally healthy (don't smoke, etc.), then what more will you do? just a thought ...
