Science of Snacks: Thinking Makes You Hungry

Posted October 23, 2008 9:05 AM

From Scientific American:

A study in the journal Psychosomatic Medicine contends that intellectual work—that's right, I'm calling writing this stuff, ya know, intellectual—induces a big increase in caloric intake. The research had 14 Canadian students do three things at different times: sit and relax; complete a series of memory and attention tests; and read and summarize a text. (It was that last activity that disqualified rodents and U.S. students as study subjects.) After 45 minutes at each task, the kids were treated to an all-you-can-eat buffet lunch. Because Canada has a truly advanced code of human-subject research ethics.

Why not? Mental work can be as tiring as physical labor, so would the appetite not also be stimulated by it? But that's merely anecdotal evidence...now there's a study to confirm it!

The problem with studies like this is they treat humans as machines - input x generates output y because of additional variable input z. They do not take into account the additional "programming" we may have received that cannot be measured. We have a bad habit in this day of plenty to treat food, especially high caloric content foods, as a reward, not a necessity. "The boy did good, give him a big lollipop." The group that did the hardest (most boring/most effort required) perceived task may have eaten more as a reward to themselves for a task completed, not from a drive created by low glycemic levels. Let's run that study again with just carrots and celery as the food choice and see what happens.

Quite so - I am a man, not a machine. Still, ply me with goodies, and see if I don't perform as expected!

I think I am hungry - therefore I am.

Yes, and they say "you are what you eat", but don't ever try to eat what you are, or they'll send you to jail.

ROFLMSAO!!! (no fricassee à la Dahmer for me)

They say fish is brain food, but fish are pretty dumb from what I've seen. And tuna laced with mercury would be anti-brain food...

I thought this was a self-evident truth, and would not have required special studies.

Anyway, one may make a guess from the behaviour of 14 Canadian Students, but far from an announcement or proper statistical evidence, the "study" is far from complete.

On the basis of such a "study" a "researcher" may announce that a careful such "study" over many years has proved the existence of water in the oceans of the world - that's about as useful a "study" as the 14 Canadian Students one.

Kind Regards....

"...proved the existence of water in the oceans..."

Yeah, but that's just crazy talk! It'd take a whole lot more than that to convince anyone of an ocean full of water...
