One of the most popular diets, people pursue low-fat diets for many reasons, including weight loss and disease prevention. Typically, the American diet derives 34% of its calories from fat.
Low-fat regimens usually prescribe fat intake of 10 to 20% of calories.
Ultra-low-fat diets, those recommending below 10% of caloric intake from fat, have been shown to greatly increase the risk of deficiencies of essential fatty acids (EFAs). EFAs are basic, essential nutrients important for heart health, mental function, skin health and many other body functions. Those on a low-fat diet might consider taking an EFA supplement. Too little fat in the diet can also prevent the absorption of fat soluble vitamins, such as A, D, E and K.M
According to FDA regulations, a food must contain 3 g or less fat in order to be called "low fat." Individuals watching their fat intake should also monitor their intake of saturated fat, cholesterol and sodium - always check the Nutrition Facts panel on products you purchase.
