The aim of the study is to investigate the effects of a low calorie Mediterranean ketogenic diet on Polycystic Ovary Syndrome (PCOS) related outcomes.
Fourteen overweight women with diagnosis of Polycystic Ovary Syndrome (PCOS) will undergo to a low calorie ketogenic Mediterranean diet with phyoextracts (KEMEPHY) for 12 week. Changes in body weight, body mass index (BMI), fat body mass (FBM), lean body mass (LBM), visceral adipose tissue (VAT), insulin, glucose, HOMA-IR, total cholesterol, low density lipoprotein (LDL), high density lipoprotein (HDL(, triglycerides (TGs), total and free testosterone, luteinizing hormone (LH), follicle stimulating hormone (FSH); dehydroepiandrosterone sulfate (DHEAs), estradiol, progesterone, sex hormone binding globulin (SHBG) and Ferriman Gallwey score will be evaluated.

| Low calorie Mediterranean ketogenic diet with phytoextracts (KEMEPHY) | Other | The KEMEPHY diet (24-29) is a Mediterranean low calories ketogenic protocol (about 1000/1100 Kcal/day) with the use of some phytoextracts. During this protocol subjects are allowed to eat with no limits green leafy vegetables, cruciferous, zucchini, cucumbers and eggplants. The quantity of meat, eggs and fish was limited to once a day (120g of meat or 200g of fish or 1 egg) Table 1. Moreover, subjects daily consumed four food supplements and liquid herbal extracts. Food supplements are high proteins (19g/portion) and very low carbohydrate (3.5g/portion) formulas simulating the aspect and taste of common carbohydrate rich foods added with dry phytoextracts (30). Liquid herbal extracts were used for their draining /toning activity, useful to reduce some commonly reported light side effects of ketogenic diets as constipation, headache and halitosis. |
