Of course. That's why the nobel prize in medicine in 2016 was awarded to a cell biolgoist studying cellular autophagy for over a decade. It must be why glucose is not an essential dietary macronutrient and our liver can synthesizie it endogenously from fats and proteins (it just felt like doing that one day and stored all those chemical pathways in our genes I guess). That must also be why ketones produced from our fat stores burn so cleanly with less reactive inflammatory byproducts. In fact the cells in our brain actually prefer ketones to glucose. There's no such as water fasting. It's just random chance that when the body is in a state of ketosis it suppresses ghrelen and other hunger hormones or that countless other chemical pathways (de)activate or change. That's right the body has absolutely no design or adaptation for scarcity of food. Water fasting is totally foreign to the human body, that's why whenever we study ancient cultures...we find they practiced purposeful fasting. There's just no such thing as water fasting, it must be a modern eating disorder.
There's no chance it has anything to do with the last few million years of our evolution. It has no benefit or relevance now.
