You've probably heard that certain types of fats are better than others in terms of keeping you heart-healthy. Now there's more good news: Scientists now know that when people use healthier fats instead of the less desirable fats, they lower their total body fat and burn more calories after a meal. Here's the lowdown on fats:

  • Healthier fats = Monounsaturated and polyunsaturated fats. These are found in certain oils (olive, peanut, canola), many nuts, some seeds, and avocados.
  • Less desirable fats = Stay away from saturated fats and those evil trans fats. Saturated fats are found in foods like sausage, bacon, cream cheese, and potato chips. Trans fats are found in tons of packaged baked goods, like cookies and crackers, and in margarine and shortening.
