A scientific study has found a connection between curvy women and smarter kids, and it may explain why men are attracted to this body type.
Researchers have discovered that the development of babies' brains depends on fat supplies that are located in their moms' posteriors and thighs, and the amount stored there might directly impact a kid's intelligence, The Sunday Times reported.
"The fat in these areas is a depot for building a baby's brain," University of Pittsburgh Prof. Will Lassek, who authored the book, "Why Women Need Fat," told the newspaper.
The fat supplies contain a chemical known as docosahexaenoic acid (DHA), which Lassek says is "a particularly important component in the human brain."
It's an omega-3 fatty acid that babies need for the development of their brains, nervous systems and eyes in their first six months of life, says a primer from the University of Maryland Medical Center.
The chemical is found in breastmilk, and it is also added to certain baby formulas.
Cambridge University reproductive biologist David Bainbridge pointed out that brain-building lipids stored in women's breastmilk largely comes from the fat supplies in their buttocks and thighs. He added men might be attracted to curvier women because there's a chance of them having smarter kids.
This is not the first scientific explanation for why certain men prefer these body types.
Research reported on last year found that when men are hungry, they prefer curvy women, because their shape suggests they have more access to food, The Daily Mail reported.
"If a man is hungry, they prefer slightly larger [breast] sizes and slightly larger [women]. If a [woman] is hungry they prefer more muscular men," University of Westminster psychologist Dr. Viren Swami said at the time. "These are clues about resources. If you are hungry you want resources and a partner who has resources. Someone who is heavier has access to food."
Meanwhile, a 2010 study published in PLoS ONE found that when men are looking at curvy women, it triggers parts of the brain that are also associated with alcohol or drugs, LiveScience reported.
ALSO ON HUFFPOST:
Women are pickier than men, right? Not true, says a speed-dating study at Northwestern University. When men remained seated and women rotated around the room, approaching a new man at every table, the women acted more like guys -- that is, they appeared to have lower standards. Regardless of gender, whoever makes the first move is less picky than the people they target, the researchers found. When we invest an effort, we’re more “into” the people we hit on than we’d be if they approached us first.
A person born to a couple in their thirties grows up to find older faces more attractive than does one with younger parents, finds a study at the University of Saint Andrews in Scotland. That is, college-aged women with “older” parents were likelier to find wrinkled, weathered faces attractive for either a fling or a marriage. The same was found for young men when considering a woman for a long-term relationship. (Take note: only a man’s mother’s age, not his father’s, influenced his attraction to older women.)
The eye’s limbal ring falls into the category of something that's overlooked but not unseen. It’s the dark circle around the iris that enhances the whiteness and brightness of the sclera (the whites of the eyes). Researchers at the University of California at Irvine asked people to rate sets of faces that were identical except for the eyes -- one had dark and distinct limbal rings and the other had none. The outcome? Whether male or female, the faces with prominent limbal rings were considered more attractive. The likely reason is that a dark, well-defined ring is a signal of youth and health -- qualities that people seek in mates. It’s thickest and most prominent through the early 20s and fades -- often becoming nonexistent -- with age and medical conditions.
When women breathe in androstadienone, an often-odorless testosterone derivative in male sweat, they give men higher attractiveness ratings than they would otherwise. After about 15 minutes of exposure, the chemical makes a woman subtly more attentive, aroused and even happier, with effects continuing for up to an hour, finds a study led by Claire Wyart at the University of California at Berkeley. (In case you’re wondering, men vary in their androstadienone levels -- and no, the chemical doesn’t brainwash women into having sex or falling in love. It’s much more subtle than that.)
How curvy a man prefers his date to be may depend on his situation at any given moment, find researchers Martin Tovee and Viren Swami. In one study, the duo stopped men at a campus dining hall and asked them to rate the body shapes of several dozen women. While all guys preferred figures that represented a normal weight, hungry men were more attracted to women on the heavier side of the range than those who had already eaten (with a body mass index ~23 vs. 21). The same thing happened in a follow-up study when guys were in a stressful situation: Compared to their mellow peers, they chose curvier, more rotund (actually, overweight) figures as their womanly ideal. The upshot: If a man feels hungry, threatened or uncertain, he tends to prefer more robust-looking female figures -- which may subconsciously remind him of strength, control, nurture and independence.
In an hour at a singles bar, average-looking women could be approached by up to four men, found Monica Moore in her study at the University of Missouri. What were these sirens doing? Making more than 35 body-language gestures -- smiles with eyebrows raised; short, darting glances; arm flexes; hair flicks; neck caresses and other “displays.” Meanwhile, Moore found that a beauty who sits there doing nothing is unlikely to be approached at all. Only when a woman’s body language expresses some interest do men feel comfortable making a move.
Like moths to a flame -- that’s how attracted we all are to the color red. Wearing red increases a woman’s chances of being asked out -- and to have her date splurge on her -- finds a study at the University of Rochester. The simple explanation: Ladies in red are perceived as more sexually receptive due to the color’s associations with fertility. Sure enough, the researchers found that single women who posted photos of themselves in online dating sites -- wearing crimson, scarlet, fuchsia and other reddish hues, even on just a T-shirt -- were more than two times likelier to be interested in casual sex than those wearing other any other color of the rainbow. For men, the color red has association of high status, which may be why women give guys -- wearing, say, red ties -- higher attractiveness ratings. Simply wearing the color may trigger a virtuous cycle: It encourages us to act sexier because we expect others to think we’re hotter (women) or more confident and powerful (men).
Your signature scent -- whether it’s Chanel, Shalimar, or patchouli -- becomes you. Literally. Fragrances may amplify and advertise your unique genetic makeup to potential partners, finds a study at the Max Planck Institute in Germany. People who share the same variants of immune system (MHC) genes often preferred the same scents (rose oil, musk, or vanilla, for instance). This suggests that particular scents work best with particular body chemistries -- and that we know intuitively what fragrances smell best on us. Indeed, a recent Czech study found that when volunteers’ sweat was mixed was their preferred perfume (versus a random one), impartial noses gave the resulting mélange much higher ratings.
Here’s another olfactory surprise: Garlic may make you smell more attractive. Researchers in the Czech Republic asked people to eat garlic cream cheese (the equivalent of two to four cloves) every day for one week, while wearing scent-trapping pads in their armpits. The next week, the same volunteers ate their bread with plain cream cheese. Which sweat smelled more attractive, more pleasant, and less intense to female judges -- garlic or plain? Garlic, naturally, but why? Garlic contains antioxidants and improve metabolic functioning, the researchers say, which may improve your body odor. Plus, garlic’s antibacterial properties help to kill the real culprit: foul-smelling underarm microorganisms.
We all know oral contraceptives are useful -- for reducing flow, cramps, and preventing unplanned pregnancies. The surprise is that the Pill may also lead to unintended romantic quandaries. A U.K. study found that women who were on oral contraceptives when they met their partners were, years later, likelier than non-users to be turned-off, sexually dissatisfied, and eager to fantasize about an affair. But here’s the interesting part: They were also generally more satisfied with their partner’s (non-sexual) contributions, and therefore less likely to separate. The researchers explain: Under Pill-driven conditions of high-progesterone and low fertility, women go for relationship-worthy qualities such as wealth and intelligence more than high-testosterone traits (biceps and block jaws) that are associated with flings. Oral contraceptives may also lead women to reverse their usual preferences in male body odor. Once a woman goes off the Pill, her other instincts complicate the relationship.
Whether she’s aware of it or not, the pitch of a woman’s voice increases a notch (becoming higher but not shrill) when she’s flirting, finds a study at McMaster University in Canada. Conveniently, men much prefer these high-pitched dulcet tones over deeper ones. A woman can strike her highest chords around ovulation, when she’s likeliest to conceive. Another coincidence: This happens to be the time of month that men give female voices the highest attractiveness ratings.
