The prevalence of PCOS is about 4-20% of women globally, leading to reproductive, hormonal, and metabolic abnormalities. PCOS result in Insulin resistance, raises the chronic metabolic risk such as hypertension, dyslipidaemia, cardiovascular disorders, type 2 diabetes and endometrial and/or breast cancer. The exact pathophysiology of PCOS is unknown, but it is evident from the study that lifestyle modifications and tailored diet therapy are the important therapeutic strategies in women. The diet treatment must be able to improve metabolic, reproductive, and insulin resistance functions, which can be reached through the design of a diet with low-calorie  for loss of weight  or maintain a balanced body mass index, limiting the intake of simple sugars and high-caloric food, restricting the intake of food with a low glycaemic index, reducing the consumption of saturated and trans fatty acids, consuming prebiotic food, and focusing on potential deficiency of  vitamin D and omega-3 fatty acid. The purpose of this study is to present a critical literature analysis on dietary management as a novel therapy strategy for the PCOS. https://biomedpharmajournal.org/vol18no1/nutritional-management-of-polycystic-ovary-syndrome-pcos-a-review/ Glycaemic index Insulin resistance Nutritional management Polycystic ovary syndrome Pathophysiology Vitamin D
