I am a senior anesthesiologist from The Netherland and a great fan (and promoter) of healthy lifestyle as well as the content of what your team is doing nowadays! I did enjoy the Eilein White podcast a lot and i am fascinated about the use of autophagy in general. I am in the middle of trying to write a scientific overview article now for the Dutch Magazine of Medicine on that topic. I would like to know your thoughts of using autophagy in the perioperative setting. I am trying to set up a prehabiliation program for the operative patients in my clinic (large teaching hospital near Amsterdam) and i am struggling with embedding the fasting regimes and autophagy advantage as a strategy of better postoperative outcome. I cannot find any literature on that. Can you comment on that or help me in any way with that topic?
