It's easy to overindulge at this time of year. It seems like everywhere you turn, you're faced with high-fat, high-calorie, sugar-laden temptations, whether it's the communal candy bowl at the office or Aunt Betty's triple-chocolate cupcakes.

The keys to preventing heartburn, indigestion, and weight gain are moderation and smart snacking. Instead of abstaining from food all day in anticipation of a heavy dinner, have meals or snacks, including breakfast, every three to four hours. Keep healthy snacks, such as fresh fruit or low-fat yogurt, at home and at work, and reach for them when you're staring down a slice of carrot cake. To help prevent overeating, try having a healthy snack 30 minutes before a party.
