A recent study shows that people eat more after doing intellectual exercises.

Researchers offered students as much food as they could eat after having them either relax, summarize a text or take memory and attention tests on a computer. Although doing the intellectual work only burned three more calories than being sedentary, those who had completed the cognitive tasks ended up consuming over 200 calories more from the unlimited buffet.

The study's authors are crediting the noggin calisthenics for bigger fluctuations in glucose and insulin levels than rest periods, that consequently triggered an increased appetite.

Since not thinking helps folks lose weight, we may soon create the "Read Asylum Diet."
