Yeah I seem to find that a bit of mild hunger (not starvation or malnutrition) is good for the mind. I have at some points in my life found myself in a bit of a dampened state, where I am constantly either a bit lethargic from the last meal, or a bit preoccupied thinking about what I'm going to eat next.

I would love to understand the physiology more, but I have a pet theory that your brain gets a bit more "switched on" when you make calories and nutrients a bit more scarce for yourself, and that maybe when you let yourself eat whatever you want whenever you want, that survival instinct gets dialed back a bit.

I've had the same thought. My pet theory is that digestion is actually a much more exhausting process then we give it credit for, and all the chemical changes happening while you absorb nutrients have a toll on mental energy. Food availability and modern 3 big meals a day culture means we never really have any time when we are not digesting.

After trying fasting, when I see a snake with a full belly sleeping in the grass like it's dead it makes total sense to me. That's what digestion feels like.
