(Newser) – Does thinking make us fat? Researchers say that intellectual activity just might cause us to pig out, LiveScience reports. Volunteers who performed a series of problem-solving tasks in a study consumed almost 30% more calories afterward than those who just sat around and took it easy. One theory: The body demands food to restore glucose depleted by the stress of thinking.

"This is a factor that should not be ignored, considering that more and more people hold jobs of an intellectual nature," said one researcher.
