A Randomized Trial of the Efficacy of Three Weight Loss Diet Interventions in Overweight/Obese with Polycystic Ovary Syndrome

Polycystic Ovary Syndrome (PCOS) is a highly prevalent, complex, heterogeneous, polygenic endocrine disorder characterized by metabolic and reproductive dysfunction that affects 8-13% of women of reproductive age worldwide. The pathogenesis of PCOS has not been fully clarified and includes genetics, obesity, and insulin resistance (IR). Oxidative stress (OS) of PCOS is independent of obesity. It can induce IR through post-insulin receptor defects, impair glucose uptake in muscle and adipose tissue, and exacerbate IR by reducing insulin secretion from pancreatic β-cells.
