The Huberman Lab podcast recently had Dr. David Sinclair [1] and talked about food causing aging due to it's relation to mTOR. I don't remember the details that well but they covered it very well. My takeaway was if your priority is anti-aging fasting and limiting protein is better, but I personally prefer wellness and that generally means consuming higher levels of protein.
