I was fortunate to need little tweaking to fix my hypoglycemia, which was a 4yr cold turkey of PUFAs even before I heard of Ray Peat. So I didn't have to take thyroid to get my metabolism going at a fairly good clip. I did one year of therapeutic magnesium supplementation of 800 m elemental daily, and it was to prepare myself to end my lifestyle of relying on soluble fiber intake for good bowel movement. When I did stop soluble fiber intake, I continued to have good bowel movement with good peristalsis driven by having enough magnesium stores.
Still, I have some Tyrone or T3 with me, when coming out of a sick state and my metabolism needed jumpstarting with a little T3.
