This explains a lot. Most guys do not know why they’re attracted to the hourglass shaped woman, but their instincts don’t serve them wrong. Check out what Gallup had to say about the subject.
“The reason narrow waists and broad hips are so prized — the reason males rate these as being attractive, even though they don’t have any insight into why they do — is two-fold,” he said. “It means, if a woman has a narrow waist, she’s not pregnant. And if she has broad hips it means that the underlying skeletal morphology is probably such that she’d be able to have a relatively unencumbered childbirth.”
Translation: An hourglass shape indicates that a woman is single and ready to mingle — or, you know, birth healthy spawn.
And speaking of those babies, women with big butts apparently have smarter kids — and tend to be more intelligent themselves. The fat stored in women’s butts — called gluteofemoral fat — has unique long-chain polyunsaturated fatty acids (science!) that are important for babies’ brain development, Gallup said.
