There’s no such thing as normal, only “normally normal”. I was told my Thyroid was fine (nope) and couldn’t get any thyroid meds to test that theory, so I self sourced some and holy crap was I right! Was burning fat off like it was my job!
Other hormones are the same way, I only feel awesome when my testosterone is on the very high end of the chart (or way off the charts for that) and my urologist at the time would only keep me in “range” which was a waste of my time. So I went to an optimization doc and now “lab range” doesn’t mean a whole lot.
My wife had the same exact experience. Couldn’t loose fat even when doing everything right, had super low energy, sluggish thyroid, I got her set up with another place and she’s doing awesome now!
Optimization docs are the way to go, downside is ins won’t pay for them, but for what you get it’s really not bad.
