Obesity Contagious?
An anonymous reader writes "University of Wisconsin-Madison researchers have found that certain human viruses may cause obesity, and by extension make being severely overweight a contagious condition. 'It makes people feel more comfortable to think that obesity stems from lack of control,' the lead researcher says. 'It's a big mental leap to think you can catch obesity.' But other diseases once chalked up to environmental factors, like stomach ulcers, are now known to stem from infectious agents."
clear cut and easy to remember: "Burger King", "McDonalds", etc.
Funny how this virus is so widespread in the United States.
I'm sure it has nothing to do with the availability of junk food and the national automobile culture.
If I fully cook it, can I eat fat people without getting fat?
There are some staggering data in there regarding the extent to which humans mimic the behavior of similar others. For example, there are statistically significant increases in the number of teenage-couples killed in car accidents among those teenage-couples who recently heard about accidents where teenage couples were killed. The increase is not observed in teenage-couples who didn't hear about the recent accidents, and is not observed among singleton teenagers or older couples who have been exposed to the news. These results have been repeated with a wide range of demographic groups, on a wide range of phenomena, and have been found to be consistent and strong. Hmm, notice a rash of mine accidents recently? Yes, I'm sure it's media focus-bias to some extent...
I really urge you to check that book out if you're interested in the instinct-level mental processes that control us without our being aware of them, or if you want to be..ah...evil?
Yes, we will have hordes of overweight people going "See, told you so! I'm sick!"
What they will conveniently forget is convervation of energy: The only way someone can gain weight is by eating too much, compared to how much energy their bodies spend on moving and keeping you alive. End of discussion.
No matter which disease one may have, you will not catch 25 pounds from taking a stroll through the mall or, say, through breathing thin air. If a disease lowers the energy requirements of the body, the cure is to eat proportionally less.
TFA isn't clear on this, but I wonder precisely what is suggested being the cause of obesity in 'infected' individuals. Are they saying people simply become unable to control the urge to eat uncontrolled amounts of unhealthy foods?
So how do you catch 'soccer moms', no bikes as kids, McD dinners and no exercise in school?
Also strange is the fact that ulcers were commonplace all over the world, due to often being an infectious disease. Yet I wonder why the Europeans haven't 'caught' obesity on the US level yet? It is not like we haven't been mingling with them for, say, a few hundred years.
Look, the cause of obesity is really very simple: the human body (and its ancestors) evolved in environments in which food was scarce, and during that time mechanisms came into being which helped to deal with that scarcity. As a result, it has built-in mechanisms to ensure that there will be sufficient energy store for the body to use for all but the most drastic of food shortages. These mechanisms include the fat store, the tendency for fat to accumulate much more easily than it's used, and an appetite control mechanism that encourages overeating (since who knows when the next meal will become available?).
Now take the human body and put it into an environment where all the food one could ever want is easily available for the taking (all it requires is a small amount of money). What do you expect will happen?
Well, duh...the body will behave as it always has: under the assumption that while food might be plentiful now, it's not likely to be plentiful for long, so better stock up now while it can.
And thus, obesity.
And the reason obesity is so difficult to deal with, and why sustained weight loss has such a lousy track record (95%+ failure rate), is simple: to fight obesity, you have to fight your own body's instinctive drive to "save up for a rainy day".

What is to say that some viruses might also be affecting this?
If some treatment can just help a person who has struggled against weight their whole life have a slightly easier struggle without harming their body in a more severe way then more power to them.

bah!*@%!
Okay, so there are lots and lots of comments here that boil down to "put the cheeseburger down!", but in a stunning reversal, I actually RTFA. True, people should try to eat well, and on the whole I agree that most people should spend a little more time walking (or biking, or jogging, or whatever) and a little less time in front of the television. That being said, the article raises some interesting possibilities. If viral activity could be a cause of weight-gain, I'd rather know about it than simply insist that the guy who's oozing out of the sides of his seat down the aisle from me has no self-control.
There was a time when illness was "obviously" the result of evil spirits playing havoc on people who were not devout enough. I'll bet at some point there were people standing around the village square commenting on how "if that fool had just spent a little more time praying than [insert sinful activity here], he obviously wouldn't be lying on the ground hacking up a lung and burning up from fever". Just because this line of research goes against what we believe to be common-knowledge isn't really a reason to jump all over it, we can be wrong.
So, no, it's clearly not an excuse to give up eating well or exercising, but I'm not going to just say there's nothing to this until there's been a bit more study.
Some bring out the best in others, some the worst. Some bring out far more.
Also, we used to run after our food and throw spears at it before we could eat.
I had to chase down a hot dog vendor today and throw spears at him before he'd stop to sell me a Chicago dog with everything and an icy cold Coca-Cola. Does that count?
