Obesity Virus Can Make You Fat

Obesity is a growing worldwide epidemic that is often blamed solely on an unhealthy diet and a sedentary lifestyle. That notion is being reconsidered, however, in light of new research. Recent findings show that some cases of obesity may actually be caused by a virus that can be caught much the same way as the common cold.

Scientists at Louisiana State University have found that the human adenovirus-36, known to cause respiratory and eye infections, can also transform adult stem cells found under the skin into fat cells and increase the fat content in humans. The findings suggest that the virus might contribute to the development of obesity in susceptible people.

Not all people infected with the virus will develop obesity and not all cases of obesity are caused by the virus, but the research does seem to indicate that in some people factors other than diet and exercise may play a part in being overweight. Experts still agree, however, that a healthy diet and an active lifestyle will help most people maintain a healthy weight.
