What sort of advice are you looking for? I wrote this, most of the links are to primary research on fasting. https://usetemper.com/learn/metabolic-fitness-no-bigger-opportunity/ https://usetemper.com/learn/metabolic-fitness-no-bigger-oppo... Most of the primary research isn't really focused on generating "advice." If I had to pick the protocol with the best direct evidence, I'd pick "early time restricted feeding" (eTRF). https://pubmed.ncbi.nlm.nih.gov/29754952/ https://pubmed.ncbi.nlm.nih.gov/29754952/ That's what Brian Johnson practices. It's not a fasting protocol I would actually recommend to most people because it's pretty inconvenient, but it's been directly studied as an intervention.
