Fat talk—making disparaging comments about your weight and body—is a female bonding ritual. Or at least that’s how it seems, to women everywhere and to psychologists who study body satisfaction. But emerging research suggests that, far from endearing you to other women, fat talking makes you come off as less likeable. Our own data show that 79 percent of YouBeauty readers fat talk all the time. Are you one of them? You might be surprised to learn that seemingly harmless comments are actually damaging your self-esteem (and your friendships).
