Dieting got you down? Just can’t lose that weight? It may not be YOUR FAULT. Biologists have identified a virus that causes animals to get fat. When the virus AD36 was injected into chickens and mice, their body fat ballooned. Could this explain human obesity?
The scientists tested 154 people for the presence of antibodies to this virus, which would indicate a prior infection. 15 percent of those who were obese had the antibodies. None of the lean subjects did.
Five other viruses besides AD36 have also been shown to cause obesity. Who knows — some day there may be a vaccine against getting fat.
