No. Our bodies need fat to function. It maintains healthy skin, provides the calories we need for energy and warmth, and supplies insulation and padding for our internal organs. It transports vitamins A, D, E, and K through the blood and helps them to be absorbed in the intestines.
In addition, the body needs fat to produce hormones, which are chemical substances that control bodily functions. Studies show that the type of fat we eat is more important than the amount. A low-fat diet high in saturated fat or trans fats would be more harmful to the arteries than a diet high in the healthy fats found in olive oil.
