A dietary system for the treatment of obesity and for the lowering of saturated fats in the blood. The system includes a diet that restricts the patient to the intake of certain foods in certain amounts and combines this intake with specific supplements. The prescribed foods comprise those low in saturated fats and carbohydrates, those having moderate amounts of proteins, and oils high in monounsaturates and certain fatty acids such as olive oil and canola oil. The supplements include prescribed amounts of vitamins and minerals. By providing the patient with a diet high in essential fatty acids, the glucagon-driven pathway of the patient is stimulated and less fat is stored by the body. In addition, more body fat is catalyzed for the production of energy for use by the body.
