When you are calorie deficient your body goes 'shit shit something is wrong let's pump extra energy in the organ that can fix this' Your body will start catabolizing itself, stealing calories from your fat, muscle and even other organs to keep your brain running at higher levels.
People are actually smarter when they are starving and stupider when they are well fed.
You may get a little dull if you miss just a meal or two and your blood glucose levels dip, this is (or rather would be) temporary if you remained calorie deficient for days.
