Introduction: Overweight and obesity are frequently present in both women with polycystic ovary syndrome (PCOS) and with Hashimoto's thyroiditis (HT). This is a limited study regarding the benefits of lifestyle changes, including dietary habits, dedicated to patients with HT and PCOS.
Objective: The aim of the study was to assess the effectiveness of an intervention programme based on the Mediterranean Diet (MD) without caloric restriction and increased physical activity to change selected anthropometric parameters in women with both health conditions.
