How do I know which fats are OK to eat

Its been scientifically proven: Eating fat helps you become slim, says Aragon. In fact, the Institute of Medicine recommends that fatty foods make up 20 to 35 percent of your total calories. This, of course, isnt an invitation to head over to the nearest fast-food joint. You have to include the right fatsprimarily monounsaturated fats (MUFAs) like nuts, avocados, and healthy oilsand stay away from processed foods that contain trans fats, such as baked goods. A report in the British Journal of Nutrition found that a MUFA-rich diet helped people lose small amounts of weight and body fat even when they didnt change their calorie intake. Whats more, dieters who took a high-fat approach needed 25 fewer days to lose 10 pounds than those who used a high-carb approach, according to researchers at Johns Hopkins Universityand that was on a diet of 30 percent fat! So go ahead and indulge (in moderation) in fatty foods that are good for your body, including beef (top round and sirloin), pork, eggs (yolks too), and reduced-fat sour cream and cheese.
