Polycystic ovary syndrome (PCOS) is endocrine disorder in women of reproductive age, which leads to reproductive, hormonal and metabolic abnormalities. Due to the presence of insulin resistance, PCOS increases the risk of chronic diseases like type 2 diabetes, hypertension, lipid disorders, cardiovascular diseases and malignancies such as breast and endometrial cancer. The actual cause of this syndrome is unknown but environmental factors such as dietary habits play an important role in prevention and treatment and lifestyle modifications are the most important therapeutic strategies in these patients. The approach of the diet therapy in these patients must be to reach specific goals such as improving insulin resistance, metabolic and reproductive functions that will be possible through the design of low-calorie diet to achieve weight loss or maintaining a healthy weight, limit the intake of simple sugars and refined carbohydrates and intake foods with a low glycemic index, reduction of saturated and trans fatty acids and attention to possible deficiencies such as vitamin D, chromium and omega-3. Given the prevalence of overweight and obesity and insulin resistance, a relatively low reduction in weight, about 5%, can improve problems such as insulin resistance, high levels of androgens, reproductive system dysfunctions and fertility in these women.
