each patient in group A was instructed briefly about the nature of the treatment regimen to gain the patient's confidence and cooperation. the patient will receive ketogenic Mediterranean diet with aerobic training program. The diet will contain approximately 9300 kJ accordingly, 37% as total fat, 18% as monounsaturated and 9% as saturated, and 33 g of fiber per day for 3 months with moderate aerobic exercises in the form of walking from 30 to 45 minutes a day, 3 times per week for 3 months.

Blood sample was taken from each woman before starting the study to measure the level of androgen in the blood and LH/FSH which will be estimated again after 3months to its level after each type of diet

Weight and height measured while the patient is wearing a thin layer of clothes to calculate the body mass index according to the following equation in both groups: BMI=weight/height2 (Kg/m2)

A tape measurement wase used to determine the hip and waist circumference of each patient to calculate the waist-hip ratio by dividing the waist reading over the hip reading (the waist circumference should be measured at the midpoint between the lower margin of the last palpable ribs and the top of the iliac crest , hip circumference obtained by measuring at the top of the iliac crest in case the waist is convex rather than concave, such as with different body types, and obesity, the waist may be measured at a horizontal level (2.5 cm) above the umbilicus .for both measurements.
