I also get a lot of mental clarity and alertness after extended periods of not eating, followed by tiredness and fogginess after a meal. This might be one reason why I'm underweight.

Unfortunately, a keto diet isn't really an option for me (vegetarian, and allergic to many vegetarian protein sources).

I wonder what the underlying science behind it is.

Science behind keto? This article explains it pretty well.

No, the science behind feeling mental clarity after extended fasting.

Unfortunately, everything I could think to Google just returned a bunch of grandiose pseudoscience.

Yeah I'm not a scientist either but I would equate this to the opposite of feeling sleepy after a big dish of pasta. Food does have a certain effect on the body especially if it's full of carbs. What I get out of fasting and keto is the opposite.
