The book's diet has been compared to a diet plan by British endocrinologist Albert T. W. Simeons in the 1950s. The book describes a multi-month, 3-phase plan that involves changing to all organic foods, with repeated colonic cleansing and liver detoxification, followed by a 2nd-phase period of daily use of human chorionic gonadotropin (hCG), typically injections, under the direction of a healthcare provider or doctor. The use of hCG in men has been found to increase testosterone, which is linked to muscle growth; however, in women, hCG does not produce any consistent or biologically significant increase in testosterone. For men, hCG can have some potential side-effects, including gynecomastia, water retention, increase in sex drive, mood alterations, headaches, and high blood pressure.
