Diet is one of the crucial aspects of managing and treating patients with polycystic ovary syndrome (PCOS). The importance of diet is not only reflected in weight reduction and maintenance, but it also greatly aids in the control of insulin levels. Many patients also suffer from insulin resistance, causing the pancreas to secrete more insulin to function effectively. Patients with PCOS can increase their consumption of green leafy vegetables, fruits, colorful and white vegetables, organic and grass-fed meats, as well as healthy fats.
