All of those are practices of fasting, saying I am not going to do X for some period of time. And it turns out when fasting from food, it's not even fasting from calories. It's fasting from specific types of calories that cause metabolic changes you don't want. So I wrote the first book, which is about fasting for performance, a working fast versus fasting for a spiritual fast.

And I fasted in a cave for four days led by a shaman who was remote from me. So I'm all by myself because I knew that if I didn't eat, this was going back to 2008, If I didn't eat six meals a day, I would go into starvation mode, which is not a real thing. And then that would make me fat and some bizarre mental gymnastics taught to me by big food.

I also knew that I would get hypoglycemic, which meant that if I didn't eat often, I would yell at everyone around me because I would get cranky. So I'm like, put me in a cave. No food, no one to yell at. Everybody wins. And the book is actually based on the psychology of fasting plus the physiology of fasting. And I say, here's how to fast without pain.
