The program uses a protein-sparing, modified fast diet that is tailored to each individual. Patients on the diet eat foods which are high in protein, including lean meats, fish, poultry, eggs, nuts and cheese. Fat intake is moderate while high-carbohydrate foods are avoided. The principle behind the diet is fairly simple, explains Rozdilsky. By restricting carbohydrate intake, the body burns fat for energy, producing ketones as a by-product.
Ketones are chemicals that have a suppressive effect on the appetite.
The diet is highly structured, with daily meal plans. Though patients have many choices, sample menus are provided, making it easy for teenagers to follow. Teens on the diet consume about 1,000 calories a day. Vitamin and mineral supplements are taken daily. Within about a week, many kids report that their appetites are decreasing.
