Reduced-fat foods are healthier for your heart, but they could contribute to a growing waistline. Some low-fat ice cream, for example, packs more calories than the regular kind. Watch what you drink. Beverages are so light and unfilling, we hardly notice when they're floating a lot of calories. A creamy coffee drink, or even that healthy-looking bottled green tea, can eat up 10 percent of your daily calorie quota.
Little things mean a lot.
But condiments are common criminals in the hidden-calorie world. Cast a cool eye on all dressings, sauces, and spreads. One tablespoon of mayonnaise, for example, piles 100 calories on your sandwich.
