According to a shocking new study by the University of Granada, men like skinny women, but other women don't.  Men looked at pictures of female models and found the thinner ones more, "highly pleasing and stimulating".  They also had a loss of self-control after looking at thinner women. 

But women found the thinner ladies unpleasant.  And the more uncomfortable a woman felt about her own body, the less she liked thin women.  They also found NORMAL-sized women threatening, because they couldn't keep from comparing themselves to the models.

Unfortunately, when men looked at pictures of OVERWEIGHT women, they had negative reactions, but other women didn't mind heavier women as much.
