and also not many people ralise that when TSH out of whack for a while increases mortality likelihood by couple hundred %,
Fat losing wise-if one is taking synthetic hormones, obviously brain is reacitng by reducing thyroid hormones production, which leads to status quo, unless one adds a lot of synthetic hormones which (mostly T3) which which then burns both fat and muscles, which in my opinion defeats its purpose
in reality of people with sluggish tyroid only few are overweight
Another scary possible side effect is
T3 increases SHBG levels, and sometimes SHBG stays elevated permanenetly for unknown reasons (some say it unlocks some gene), so that basically sends you straight to TRT (as you end up with very low free test which is one who does almost all action, so basically you end up being hypogonadal)
If one is using T3 only or insufficient T4 that has some implications on its own-
T4 is needed as brain need some t4 and also brain uses its own fT4 which needs to be obtain by converting T4 by brain itself, (not sure of full implications here)
hair needs fT4.... etc....
And there are other possible issues as well... So in my opinion its simply is not worth taking risk.
