Bacteria and Obesity

Two mice; the mouse on the left has more fat s...

Guess which mouse has the bacteria inside it.

 

Here is a story that might make you feel better about eating too much at Christmas get togethers. According to a study in China, it isn’t how much we eat or how little we exercise that makes us fat, it is what bacteria we have in our colons. I found the article in the Financial Times through Instapundit.

 

Obesity in human beings could be caused by bacterial infection rather than eating too much, exercising too little or genetics, according to a groundbreaking study that could have profound implications for public health systems, the pharmaceutical industry and food manufacturers.

The discovery in China followed an eight-year search by scientists across the world to explain the link between gut bacteria and obesity.

Researchers in Shanghai identified a human bacteria linked with obesity, fed it to mice and compared their weight gain with rodents without the bacteria. The latter did not become obese despite being fed a high-fat diet and being prevented from exercising.

 

Personally, I think that diet and exercise might have a little to do with obesity. If this study proves to have merit than it might pave the way to more effective weight loss methods. This isn’t the only article I have read indicating that human intestinal bacteria might have a profound impact on our health and clearly a lot more research needs to be done in this field.

 

Here is a sentence in the middle of the article that ought to make anyone think for a minute.

 

Governments around the world are grappling with an obesity pandemic.

 

Do you know how truly weird it is that governments around the world have to deal with obesity. It wasn’t that long ago that the major preocupation of most governments was preventing their citizens from starving. The fact that a large portion of the population of the world may suffer from having too much food is simply unprecedented in human history and represents a triumph of man over nature, if not an entirely unprobematic one.
