Feed A Cold

Louisana researchers have found that a common cold virus, adenovirus-36, can cause stem cells to turn into fat cells, lending credence to the oft-disputed theory that some people become fat due to being infected with a fat-causing virus. This discovery fuels speculation that obesity may one day be at least partially preventable with a vaccine, although lifestyle causes would remain. For those who already have the "fat virus", a vaccine would be useless. Additionally, scientists say that the idea that obesity is infectious remains unproven and unlikely.

Unproven and unlikely, but I can already hear an angertwink saying, "Ooh, I don't go to bear bars. I don't wanna catch fat."
