Not Snacking at All

While mindless snacking can pad your waistline, thoughtful snacking may do just the opposite. People who eat several small meals and snacks a day are more likely to control hunger and lose weight. Snacking helps keep your metabolism in high gear, especially if the snacks are protein-rich. Nuts are a good, high-protein choice, and research suggests people who snack on nuts tend to be slimmer than those who don't.
