A low-fat, low-cholesterol diet is recommended for anyone trying to lose weight, lower cholesterol or prevent chronic medical conditions such as diabetes or heart disease, according to Everyday Health. A low-fat diet is an eating plan one can follow throughout his lifetime to maintain good health and proper nutrition.
Some fats are necessary for proper nutrition, and it's important to understand which fats support proper body function, explains Everyday Health. Nutritional guidelines suggest 20 to 35 percent of one's daily caloric intake should come from fat. The primary source of fat intake on a healthy eating plan should be unsaturated, monounsaturated and polyunsaturated fats, which come in the form of olive, corn and canola oils. Saturated and trans fats increase LDL cholesterol levels and the risk for heart disease and should be reduced or avoided.
Saturated fat is found in animal products such as red meat and dairy products, and it should make up no more than 10 percent of caloric intake, according to Everyday Health. Trans fat, also known as partially hydrogenated oil, is typically found in margarine, shortening and baked goods. Trans fat is used to increase the shelf life of many foods such as cookies, pies, chips and cakes and should be eliminated from the diet altogether.
Low-fat diets emphasize vegetables, fruits, lean sources of protein and whole grains, according to Everyday Health. How food is prepared is also key to keeping fat content low. Baking, roasting and grilling are ideal methods, while deep-frying should be avoided.
