Yes, I am openly admitting to a pathology here. It happens. And for my doctor, the proof was that I ended up with tachycardia as my body panicked while my glucose dropped because my brain was literally refusing to use the available ketones. (Now, we don’t know to what degree. I can function “normally” in some regards on ketones. But NOT with low serum glucose levels).
So, it IS a pathological case. And one that I was NOT AWARE of until we teased it out.
My next tests will involve PSMF approach to see if “any” fresh calories help the symptoms, or if it is literally requiring a certain Serum Glucose. I need a decent “Mental Test”. An average speed at sudoku, or the like…
Also, Michael, there are some brain functions that might REQUIRE glucose (ie, cannot be done with ketones). I remember Bret Scher or someone mentioning this, and saying “it’s a really small amount”… But it clearly implied 100% ketone utilization was not truly an option…
