As the supply of svelte women diminishes, men either adapt or don't reproduce unless they have the resources to appeal to one of the dwindling numbers of the really hot chicks. If tastes were truly changing based for some deep rooted (inexplicable) reason, then they'd be telling actresses to look like the 150# (+) Hathaway, or better yet, Queen Latifah.
You do realize that until about 1900, the worldwide standard for a beautiful female figure, even in Western society, was far closer to the "Queen Latifah" mold? By the way Stewball, most men have ALWAYS preferred a woman with large breasts and a sizable ass as opposed to that picture of Kunis, who has no butt or tits viewable to the naked eye.
And the 150 pound version of Hathaway is still thin, but at least she looks normal and healthy in that picture, unlike the emaciated 125 pound model.
