A Micro-RNA Causes Metabolic Problems In Obesity

Who knew that there is a micro-RNA called "more Calories in than out"?

Scientists have identified a key molecular player in a chain of events in the body that can lead to fatty liver disease, Type II diabetes and other metabolic abnormalities associated with obesity. By blocking this molecule, the researchers were able to reverse some of the pathology it caused in obese mice.

That is the only thing that can cause obesity.
