Your comment ignores the main point of the comment you are replying to: namely, a lot of reporting on studies that find that some intervention increases lifespan ignore strong evidence that the same intervention fails to increase (or worse, actively decreases) healthspan. A diet low in protein for example, will tend to increase your lifespan while tending to make you one of those 70-year-olds (or 60-year-olds if you're unlikely or maintained a diet very low in protein) with very little muscle left -- and no way (that we know of) to regain muscle: at that age, neither exercise nor increasing dietary protein quantity and quality will significantly increase muscle mass even if muscle mass is very low. I suspect that something similar can be said of not doing enough exercise. We are commenting on a press release from a university, i.e., written by professionals whose job is to increase the prestige of their employer. It is rich for you to criticize Peter Attia, M.D., and ignore that little gem. At least Attia is trying to understand some aspect of reality more fundamental than impression management and increasing the public's awareness of whatever their employers tasks them to target.

> A diet low in protein for example, will tend to increase your lifespan while tending to make you one of those 70-year-olds (or 60-year-olds if you're unlikely or were very protein deficient) with very little muscle left Low muscle mass is correlated with shortened lifespan, though. Very low muscle mass is known to be a high risk for early mortality. > It is a rich for you to criticize Peter Attia, M.D., and ignore that little gem. I don’t feel bad at all for criticizing Peter Attia, especially after his ringing endorsements of the Oura Ring and claimed “investor” status were revealed to be a contractual deal where he got shares in the company in exchange for promoting the Oura Ring. He’s been revealed to be very oriented toward fame and self-promotion, as evidenced by his recent claims that Kevin Spacey’s accusers were all wrong and Kevin Spacey was totally innocent after Kevin Spacey’s team set up a promotional dinner between Attia and Spacey. I know a lot of listeners develop sorts of parasocial defensive relationships for their podcasters, but you can’t deny the irony of a CVD-focused podcaster starting his podcast career deep into Ketogenic stuff before he saw the writing on the wall and backed off.

TL;DR: In the 1980s, Maria Fiatarone got 9 patients in their 80s and 90s to do 2 months of progressive resistance knee extension training. The minimum increase in 1RM strength was 61%.

  OK, but did the subjects add any glycogen storage capacity to their musculature? The muscles capacity to remove glucose from the bloodstream (and store it as glycogen) is very useful in avoiding uhealthy, high levels of glucose after a meal containing carbs.

    I don't know. Regardless, a 61% increase in strength is astounding.
