Was it Breedlove talking about fasting a while ago on a pod? Whoever it was the referenced an old book and I started reading it and the stuff people have done with fasting is unreal. I think it’s great. Often do 18:6 or 16:8 most days sometimes a 24 hour and have done a 3 day .

Think this was the book https://dn790009.ca.archive.org/0/items/fastingcure00sinciala/fastingcure00sinciala.pdf
