It should lessen the stress on the heart I'm sure. Though from what I've read the changes to the heart are permanent to a large extent.
But if Ruhl were to get completely off he would be in an extremely weakened state and whatever health issues he has might finish him right off... just complete speculation on my part, just a hunch. Tapering off would be good, but imagine if he's been on daily thyroid, steroids, gh, insulin for a couple of decades straight and stopped all that at once. Sounds dangerous to me, the whole system would go into shock, blood sugar would be all over the place, thyroid all messed up, huge water loss all at once etc. 
I remember on musclemayhem a decade ago or so when cswole said he got off his bottle a day habit. He was complaining of feeling like utter shit, couldn't sleep for weeks etc. Sounded like a junkie going cold turkey. 
ah yeah good point,lol.
i was thinking for some reason its just the steorids,haha.
he will live on trt or soemthing liek that,will feel very bad till ge gets small.yes iner organs i dont see how they can get smaller in size.
would suprise me if hes off good blood sugar and liver health,i remember his advice for gaining size was the daily proteina nd then top that up with whatever you can fit in the stomach.
i forgot the insulin, t3s , gh.
hell i know t3 levels will recover quickly, if not, t4 for life.
hgh, tbh i dont know if exogonus gh will shut down endogenous production, someone look that up.
insulin, well, that he can stop,if hes diabetic,then its gonna be type 2.
not sure he will ta[per off at all,though.
diabloblanco, yes theres studies theyre very clear eating little is best as far lifespan is ocncerned.
btw im not even sure ruehl is one of the biggest eaters
