Thank you for stalking. The paper you cite is preclinical work in mice, and the mechanistic association between starvation conditions and autophagy induction were already well understood before this paper. (That was, in fact, the Nobel-winning work on which you commented.) Any consequential claims of autophagy are unsupported by data in that paper, even in mice. The claim that autophagy has net "health benefits" or "life extension properties" in humans is completely unsupported and not something on which there is professional medical guidance.

HN is replete with medical and health claims that should not be propagated by responsible people. Face it: IT professionals don't have expertise in this area, but that doesn't apparently stop you from having opinions and propagating them authoritatively as truth. If you'd like to do original research in this area, please do, but don't spread misinformation as if it's factual.
