Need to lose a few pounds? Trying to lose the baby weight? That's great for you—but things might not turn out so well for your partner. A new study from Monmouth University's Department of Psychology reports that dieting makes people more likely to commit infidelity.
Wait, what? Apparently, it has to do with self-control. Of the 32 college students who participated in the study (okay, yes, it's a small sample!), half were placed under food restrictions, which made them much more likely to accept a date offer—even though all of the participants were in committed relationships. Researchers explained that resisting temptation in one area of your life—like with dieting—usually decreases self-control in other areas.
Our advice? Just eat when you're hungry.
