I wasn't trying to imply the diet approach didn't work. I was just trying to make it a little more clear how the mechanics of the measurement could lead to misunderstandings occurring in the absence of sharing details pertinent to the process of conducting the measurement.

I too have experienced what happens when you have to run the gauntlet of physicians who seem to have stopped thinking upon receipt of their medical degree as well. Hence the encouragement to coordinate with a physician. Not necessarily the one who might not be doing a great job working with you to manage your health.
