Researchers made the discovery by splitting 14 university student volunteers into three groups for a 45-minute session of either relaxing in a sitting position, reading and summarizing a text, or completing a series of memory, attention, and vigilance tests on the computer.
Then the participants were invited to eat as much as they pleased.
Though the study was preliminary with a small number of participants, the results were stark.
The students who performed the summarizing task consumed 203 more calories than the students relaxing, and those who performed the computer tests ate 253 more.
Blood tests showed that intellectual work made the students more hungry by sending glucose and insulin levels haywire.
Well it may explain why today’s kids are getting fatter — while achieving better exam marks.
The researchers concluded: "This is a factor that should not be ignored, considering that more and more people hold jobs of an intellectual nature."
This should make you think twice about skipping out on exercise.
