Canadian Researchers Say Hard Thinking Leads To Big Meals 150
Anti-Globalism writes with an excerpt from a story at Ars Technica, according to which "a preliminary study from a group of researchers in Quebec suggest that working on a computer may have an additional impact on our waistlines: taxing mental effort appears to cause people to eat significantly more food, even though it doesn't burn many more calories than sitting around and relaxing. The publication, published in a journal called Psychosomatic Medicine, arose from a pilot study that the researchers were performing in order to determine whether a potential connection between mental effort and eating was worth following up on."
Vindication (Score:5, Insightful)
First to clear up a small matter. Merely reading the summary is somewhat misleading. While the brain's actual energy usage stays consistent, the study shows that blood sugar and insulin levels varied radically during the tests. Furthermore, the subjects in the tests showed marked signs of stress, including heightened levels of cortisol in their bloodstream. Here's the relevant section:
What's particularly interesting about these results is that two things have been known for a while now. The first is that the brain's energy usage is relatively constant regardless of the task. However, it has also been clear that severe mental activity can result in signs of fatigue, exhaustion, and greater energy consumption. I personally can attest to these symptoms after several extremely challenging programming tasks. (Ever tried cobbling together an emergency replacement JSP engine inside 3 hours? That was... interesting.) Yet this is simply at odds with the scientific evidence on hand.
This study finally offers evidence to break the impasse. It is the first evidence to clearly show that there is a physiological and not merely a psychological effect from extreme mental work. I look forward to hearing the results of future studies. Perhaps a more effective diet or lifestyle can be devised to make knowledge workers more effective.
