A new article from the British Journal of Psychology:

Male students had to judge which females (on pictures) they found most attractive. (And they were asked when they had eaten the last time and how much).

The hungry males preferred well proportioned females, those who had eaten enough (or even more) preferred skinny females.

Men being too fat is, therefore, the main reason for the choice of the skinny models.

Wolfgang (not really serious, but the article is genuine)
