Thanks for your detailed thoughts baout this subject.
However, I need to correct you on one statement you made:
"I'd hazard hazard an educated guess the reason this cookie phenomenon lowers cholesterol is because the thyroid needs carbohydrate."
The thyroid itself doesn't metabolize glucose for its own energy production. It can't because it lacks the requisite enzymes. On top of that, the energy demand of te thyroid is very small. But hormones influence the rate of glucose uptake and utilization by other tissues and organs. The lipoprotein excursions that we see in LMHRs is in all likelihood not due to thyroid dysfunction.
