A study done by the romanian scientist Magdalena Pasarica claims that a common virus responsible for flu or eye infection, is also involved in some obesity cases. The study was presented at the
American Chemical Society from Boston.
According to the study coordinated by the scientist from Pennington Biomedical Research Center the virus determine the adult cells from the human body to transform into adipose cells.
There are now more studies undergoing for the making of a vaccine for this adenovirus-36 (Ad-36).
So according to this study, you may caught obesity the same as a common cold.
I have a feeling that soon people will rush to the blood testing centers that check for the presence of this virus.
