Not sure how to quote selectively so in response to this
"To summarize, the absence of death would be synonymous with the presence of life, not the presence of life quality."
The long term health benefits of GLP drugs are very real. I suspect how real it seems might depend a bit on how close to the pointy end of those events you might be.
I think I can definitely say that tirzepatide ( plus a bit of reta and cagrilintide ) substantially contribute to my physical health , likely lifespan and healthspan and mental health.
As a result of testing , I probably have a risk of developing clinical heart failure or other serious cardiovascular disease, stroke or death somewhere around the 20-30% range over the next decade, assuming I maintain weight and take statins, ezetimibe, clopidogrel, beta blockers, ace blockers etc. Now at age 58 that is not fantastic, but were I to regain the 80 kilos I have lost, those odds start to look really awful, my best guess is my odds of getting another 10 years of reasonable health becomes very small, as in pretty unlikely.
Given every other time in my life I have got my weight to normal or near normal levels, I have managed to regain that weight, the main thing reducing that risk of putting the weight back on, which would add a lot of stress given the health implications, is GLP drugs. As I initially lost the weight without them and kept it off for a year afterwards, I know exactly how hard it is to keep the weight off, and how hard it is to keep the weight off with GLP support, which is not super easy, but I no longer have to choose multiple times every day to not eat when hungry, and it more or less works so long as I stick to eating foods in my allowed categories, and works without constant mental effort.
So not only do the GLP drugs reduce the chances of unpleasant physical illnesses in my near future, they substantially reduce the stress of worrying about it happening. And I imagine my current quality of life is better than it would be after a stroke or heart attack or heart failure. And it means I can stay the thinnest I have been since my early teens, which makes doing anything and everything easier and more pleasant, and I can do it without suffering constant hunger. So a definite win for quality of life.
The replacement dose TRT ( prescribed rather than grey ) I am also on might increase muscle a kilo or 2 , and maybe boosts energy and libido a tiny bit? But the effects are very minor compared to GLPs. The HGH I am also taking might increase muscle a tiny bit, and did seem to reduce waist circumference, and might be helping me maintain my weight, but is riskier, as even the 1.5iu I was taking turned out to be much too much possibly increasing cardiac failure risks, so now on 0.8iu and will recheck igf-1. One of the few studies on TRT and HGH in older males showed a 5% increase in lean mass from the combination of both HGH and TRT, so the effect is not huge.
