Guys succumb to the allure of the holiday cookie tin for a very simple reason. Holiday treats aren’t available year round, so people tend to gorge when they appear, says Alexis Conason, Psy.D., a New York City psychologist who teaches mindful eating. Ironically, the key to fighting that impulse is buying more holiday cookies. “You won’t worry about them becoming unavailable again, and you’ll focus more on whether you really want one,” she says. Stow the junk in the freezer and you’ll have more time to reconsider the decision as it thaws.
