The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.
Let's talk about why fasting works to create this heightened state of alertness, yet calm brain state. Fasting increases levels of adrenaline, also called "epinephrin" in the brain and body. And when our levels of epinephrin and adrenaline are increased, we learn better, we can focus better. There's terrific data supporting that.

Fasting, in particular, prolonged fasts, do increase the amount of adrenaline, also called epinephrin, in the brain and body. And as we'll next explain, epinephrin, adrenaline does have a powerful effect on the various inflammatory cytokines and on the immune system in general.
Yeah, I think the uh the known increase in adrenaline from being slightly fasted is awesome for cognitive function. Um I think it allows people to ingest fewer stimulants in the form of caffeine. You can, you know, you don't need as much caffeine when you're doing some fasting.
the benefits yeah energy a lot of a lot of extra energy I know it like boost up your noradrenaline so that's kind of fun
