Will He Cheat? How To Tell

Will He Cheat? How To Tell

If you're worried your guy might cheat, try checking out his waistline. A new study says the size of his belly may reveal whether he'll stray.

ven the tiniest suspicion that her man might be unfaithful can turn some women into an investigator worthy of a guest-star role on CSI. Now, a surprising new study suggests that women with huskier
“23 percent of average-sized guys said they'd cheat on their partners if they had the chance, but only 11 percent of very heavy men said they'd stray.”
mates can breathe a bit easier on this front.

Here's the scoop: When researchers surveyed 1,000 men, 23 percent of average-sized guys and 19 percent of moderately overweight men said they'd cheat on their partners if they had the chance. However, only 11 percent of very overweight men said they'd stray. "The more you weigh, the less interested you are in sexual dalliances," said men's health expert Sascha Rusch of the health institute Epicure, which commissioned the study.

What's going on here? A lack of testosterone, the hormone that fuels a guy's sex drive. "The larger a man's stomach is, the less testosterone he's likely to have," says Harry Fisch, M.D., author of The Male Biological Clock and director of the Male Reproductive Center at Columbia University Medical Center of New York Presbyterian Hospital.

Of course, just because he's less likely to cheat doesn't mean that obesity is a good thing. A recent study from Duke University revealed that obese people were up to 25 times more likely to report sexual problems (such as lack of desire and impotence than people of average weight). "If his waist is more than 40 inches, it's a sign to slim down," says Fisch. So the goal is to lose the extra weight... while keeping those excellent values intact.
