Staying active with Wii Sports and Dance Dance Revolution isn't the only way video games can help you lose weight. Sometimes, all you need is a distraction to keep you from overindulging your appetite.
According to Cynthia Sass, RD, a nutritionist and spokesperson for the American Dietetic Association, playing with a portable can help you forget about food: "When you start to visualize your craving, you've already lost half the battle ... A video game occupies your eyes, your hands, and your mind."
Of course, if you insist on playing games like Cooking Mama or Cheeseburger Town, you're probably not going to get the desired effect. Sitting in front of a chocolate cake while an oscillating fan blows its saccharine aroma towards you isn't going to be too helpful either. But if you can manage to avoid food-based games and afternoon desserts, and if you'd like to try something new to make you stop thinking about eating, grab your DS the next time your stomach starts asking for a snack. Maybe that'll do the trick.
