Well, some people fast not to increase the blood flow to the critical parts of the brain, but rather because eating the processed foods that are commonplace in conventional society fill you with “toxins,” and by abstaining from food, your entire digestive system is allowed to “rest” due to the lack of food coming down the pipes, and focuses on repairing itself and expelling toxins.

Toxins can, supposedly, contribute to brain fog, but most of this is just speculation on the part of fasting advocates, who may just be experiencing the placebo effect.
