Researchers at the Yale School of Medicine want to know if gender affects our ability to put down the french fries and pick up an apple instead. A new study, designed by researcher Tomoko Udo, seeks to understand why women and men tend to react differently to food. Existing research has hinted at neurobiological similarities between addiction and compulsive eating, but Udo want to go deeper. She’s looking for evidence that women are more prone to addictive eating than men. Her work could have big implications for the obesity epidemic and beyond, experts say.
