Canadian Researchers Say Hard Thinking Leads To Big Meals
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."
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.

Long hours computing causes me to forget food... and sleep... and water... and stretching... but interestingly, not sex! Perhaps there's a study I could take part in?
On the other hand, I'm a vegan, so maybe I'm immune. I don't ever crave cheese or animal fats, having not eaten any of either for many years.

... the body thinks that due to the mental taxation, that the overall body has been taxed in the same way, and therefore is tricked into expecting that the body will require food. maybe when the body exercises or performs physically intensive tasks, it creates the same signals in the brain that thinking hard does. I didn't have time to RTFA so maybe they said that already.
I am a _little_ from ideal weight because sometimes coding is mentally exhaustive that I don't feel like doing exercise. However, when stuck into a particular computer task which I want to get out of the way, I don't feel like eating and don't miss food, just need to have a (non soft drink) drink.

That, and setting on your ass all day.
Seems consistent with what I found happened to my body when I changed my eating habits. I now eat only fruit in the morning and after that I eat bread, but only when I feel a bit hungry. As soon as the hunger is over I stop eating. I do not get my 3 meals a day, it is more like 5 or 6 very small meals and one regular one for diner. I now fit the same jeans as 19 years ago (501, 31" / 34") and I feel better during the day; no more cravings.
I have got a hunch that eating small meals keeps one's insulin and glucose levels more constant than eating big meals.

Never attribute to malnutrition that which can be adequately explained by stupidity.
So if I understand this right and thinking people put on weight, then thoughtless people should lose weight.
I'll go around being rude to other people and when they complain, I will tell them it is my special thoughtless diet.
The good news is, I didn't have to think very hard to work this one out. I can feel those pounds coming off already!
I am anarch of all I survey.
Um. I'm sorry. Having just RTFA, it's just just working on a computer, they specifically used a mentally challenging task which just happened to be on a computer. Still, not your fault. Just another case of, somewhat bad summary. Title and conclusion is spot on, though.

I know then when I'm really working on challenging programming, I get hungry - very hungry. But when I'm just doing routine stuff that isn't all that taxing I don't. So that would tend to suggest that "hard thinking" requires more fuel. I snack a lot when I'm coding - calorie-wise it must be heading for the 3000-4000 a day mark and some of it's non-too healthy. Yeah, yeah, just another morbidly obese coder you may be thinking. Well, no. I weigh 70kg and always have and probably always will. No matter what I do my weight is a constant. At 6ft tall that makes me pretty skinny. I seem to have a gene for some sort of metabolic homoeostasis - if I eat a lot more, it just speeds up to compensate and vice versa, so my weight stays pinned at 70kg. I have no idea if that's really what's going on but my siblings are the same.
That's what sucks about being too smart, there's hardly anything that makes you think hard.
You just got troll'd!
You have a choice not to read their website, and people are free to form their own opinions. They don't need to be babied when reading certain ideologies (what, are you afraid that people are going to turn into Nazis after reading Corrupt.org?).
Does it also bother you that Corrupt supports black nationalism, Tibetan nationalism, and Jewish nationalism (in the tradition of Rabbi Mier Kahane)? Oh wait, its only bad when whites try to assert their ethnic identity.
Please try paying more attention in the future.
Throw some hot pockets my way and I'm good. Despite the misconception of 'lazy' people working on computers... I don't think I've ever met an overweight IT.

Ok, I'm fairly certain that you're just trolling here, but I'll bite.
First, I'm guessing that you probably don't work in IT. I do, and I can attest that when I'm sitting in front of the computer at work I'm not just doing nothing (95% of the time, the other 5% is spent here or checking my mail or RSS feeds), I'm busy working on whatever problem is at hand. Despite what you might believe, writing code is HARD. It definitely falls under the category of "mentally taxing." It's not like sitting in front of the idiot box and just soaking in whatever crap happens to be on at the time. Even when it looks like I'm just sitting there staring at the screen in a zombie-like state I'm actually turning the problem over in my head, trying to determine the best way to solve it.
As far as eating as something to do when one is "sitting one's ass" is concerned I personally don't eat just to pass the time. I would go so far as to say that this is true for most people. I eat when I'm hungry, and work (mental or physical) makes me hungry. Also I tend to think better after a reasonable meal (I avoid pasta, rice, or anything carb-heavy or I'll just want to sleep), and I've learned to recognize when my brain is not performing as well as it should due to hunger. Most of the time by the end of the day I'm close to mental exhaustion and my wife will be the first to tell you that I'm not fit for conversation until after dinner.
The bottom line here is that anyone who equates working at a computer all day and watching TV has obviously never had to do it for a living.

I noticed myself doing this a few years ago. I feel it's not hunger so much as a craving for distraction. Like my brain saying a queue is full and needs to process. It happens when I'm thinking hard and don't want to be -- in a jam, not on a roll.
I've caught myself muttering and pacing with a bag of chips. There's a Pavlovian absurdity to it. Haven't managed "hear bell: prove lemma" yet.
It's not the sort of thing people can research, but it seems directly analogous to smoking cannabis and getting the munchies.

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.
For the average person mental tasks do not significantly increase the consumption of energy, however there is a correlation between IQ and amount of energy that can be brought to bear. Moreover, thinking dramatically increases the consumption of glucose by the brain, so feeling hungry after thinking might be a reasonable response from the body to request replenishment of basic sugars.
Well Kahanism certainly worries the fuck out of *me*.
The apparent paradox is solved when we think in terms of hormonal response.
We don't overeat because we've expanded more energy, but because hormone levels, especially insulin, have changed in the blood. So the increased mental activity might have had no effect on calories expanded but it did have a significant influence on cortisol and insulin.
Don't get too excited over this study. There were only 14 participants, all university students so not even slightly representative of the general population. Maybe for them doing heavy mental work was associated with stress more than it would for a cashier or a janitor, and relaxing was really uncommon. Some might have been there for the free buffet because they are too poor to afford real food, etc. With n = 14 there's just no meaningful conclusion you can reach.
Of course. Haven't you ever played chess while eating lunch? You consume your food without realizing it, causing you to eat more. The mental challenge of chess causes you to think which in turn calls for more food.

If I am sitting behind my PC I sometimes do not smoke, drink and eat for 6 hours straight. It's not that I'm addicted to computers, but my brain is too occupied with a set of pixels that it forgets about everything else (hence why I am running all kinds of social apps on my pc).
Because I am not doing anything physically behind my pc my appetite isn't that large either.
If fat is such a big deal then do physical exercises (sport, skateboarding, jogging).
If health is also important than eat healthy instead of going to the [insert favorite junkfood restaurant here]...
Loosing weight by eating less is not going to work. It is better to eat much (preferably also healthy) stuff (replace you Coca Cola bottles with Coca Cola Zero or Pepsi max or whatever you like) and engage in physical demanding activities.

BTW, there is more than one type of IT. Programming is generally more taxing than support. Although support has its moments.
Oh yeah, I know "IT" is a pretty broad term. Honestly I had just woken up and, you know, I hadn't eaten yet ;-)

No. I have NOT been smoking pot; I've been thinking - a lot.

I always considered this to be a know fact, i was aware that the brain utilized glucose at a constant rate, however in my personal experience any prolonged period of mental exertion leads to hunger and lethargy, common sense. However rather interestingly i have found that the intensity of my work regardless (to an extent) of time does indeed affect the amount i eat and my appetite.

I think they missed a very important part of why they eat, not because they NEED the food, but because they need the break and rest from the exertion. Follow me if you will down this dark road... ...yet...I train like an sob in the gym and actually do still burn a lot of calories playing drums at home, but when I get on a project that requires new thought patterns or
I am a programmer, I tend to eat a lot more when I am delving into uncharted territories...so as to
give my mind a break and also enjoy something that maybe counters the negative affects of not getting something to work right away. You get the symbolism for eating you feelings, well in the same way, I eat my senses.I am not fat
changing the way i think to get through....it rises he stress levels, and therefor gives no immediate return for my work. I turn to food to calm me down, between snacks and meals i can stay stress free so to speak. I know a lot of people where I work are the same...we all have deadlines creeping up, we decide to go out for lunch together and take an extra 30 minutes because we got desserts or went to a buffet....when we come back we have escaped for a mere 1-2 hours from the drudgery of coding and a little more stress free, we can return with a clear head ready for more...
if you only take a small break to eat a little meal, and then what can you do for the rest of your meal...everyone else is gone, this means you stay at your computer, and might as well keep programming, guess what...you didn't relieve any stress. You might get more if you take a little longer lunch enjoy more food with friends and lose yourself in your meal to come back a more positive and productive force.....wow that was a mouth full ( no pun intended)
