It's at the top of many people's New Year's resolutions list: Stop snacking! Now researchers have found a great trick that will help you cross that one off, pronto. In a study at the University of Southern California, Los Angeles, participants were given popcorn to nibble on as they watched a movie and were told which hand to eat with. Those who used their non-dominant hand ate 30 percent less than those who didn't.
Your action plan: Next time you sit down in front of the TV with a snack, make sure to use your weaker side. "Switching sides disrupts that unconscious hand-to-mouth pattern," says lead researcher David Neal, Ph.D. "You slow down and realize the food is bad for you."
