Obesity

According to a headline from the Daily Telegraph weight gain is linked to a switch in the brain. I found this article very interesting because it was not quick to just presme that people who suffer from obesity are just gready. Apparantly if this "switch" is faulty then the body will not recognise that it is full, and the brain will send out more signals to eat. The article suggests "drugs could be used to suppress this switch and help people get back to a healthy weight."
It is based on a study with mice, however the problems with this is that mice and humans have very different metabolisms , so the results will need to be confirmed in humans. If this is found I think this will help alot of obese people, it will also prevent a lot of painful and sometimes unnecessary procedures that people go through to loose weight.
