Polycystic Ovary Syndrome (PCOS) is the most common reproductive disorder in the world, affecting an estimated eight to 20 percent of women of reproductive age, almost half of whom are unable to conceive. PCOS is also associated with increased risks of heart disease, ovarian and endometrial cancers, and type 2 diabetes.

In this clearly written guide, backed by science and personal experience, Drs. Jason Fung and Nadia Brito Pateguana identify the symptoms of PCOS and reveal its root cause: excess insulin. They then show how to prevent and reverse PCOS with a low-carb diet and intermittent fasting. As a bonus, fifty recipes and a variety of menu plans are included to put new knowledge into (delicious) practice.
