The biggest transformation in my thinking about health over the past few years, by far, has been studying the work of Dr. Ray Peat and bioenergetics.

how has it transformed it? (i know it is a broad an infinite question)

how did it change it in the realm of fasting? how did you change what you practically do? what was the difference it brought?

Just that I now think in terms of optimizing metabolism/energy as the core goal. 

It also made me change my mind on a lot of stuff I previously considered very healthy (notably Paleo diet, low carb, and fasting).
