The participants will follow intermittent fasting diet only for 12 weeks

The participants will receive High Intensity Interval Training program for 40 min, 3 sessions per week, in addition to intermittent fasting diet for 12 weeks,

Fasting for 14 hours and eating window for 10 hours (1400 kcal) as prescribed by nutrition specialist. Intermittent fasting is an approach of eating that focuses on when you eat rather than on what you eat.

• During fasting hours (fasting window) the participants are allowed to drink water, tea, coffee and drinks without sugar.
• During eating hours (eating window) the participants will follow 1400 kcal diet.
• The diet targets recommended with respect to high intake of vegetables (3-4 serve daily), fruits (1-2 serve daily), fish, lean meats and poultry (3-4 serve daily), fat free and low fat dairy products (2-3 serve daily), and legumes, nuts and seeds (4-5 serves per week), carbohydrates (3-4 serve daily).

Body weight will be measured by using weight and height scale before and after treatment program.

It will be calculated by dividing weight in kilograms divided by height meter square.

The waist circumference will be measured by tape measure from the narrowest point between the lower border of the ribcage and the iliac crest at the end of normal expiration.

Hip circumference will be measured at the widest part of the hip using the tape measurement.

Waist /hip ratio will be calculated by dividing waist circumference by hip circumference.

Venous blood sample will be collected from each participant to determine level of oral glucose tolerance test.

The 2-hour plasma glucose level <140 mg/dL (7.8 MMOL/L) is considered normal. A blood glucose level between 140 and 199 mg/dL (7.8 and 11 MMOL/L) is considered impaired glucose tolerance, or pre- diabetes.

Venous blood sample will be collected from each participant to determine level of fasting plasma insulin level at least 8 hours of fasting. Normal insulin level is 3-8µIU/ml, mild insulin resistance is 8-10µIU/ml, moderate insulin resistance is 10-12µIU/ml and severe insulin resistance is >12 µIU/ml.

Polycystic Ovary Syndrome Quality of Life scale (PCOSQ) will be used. It is composed of 26 items categorized into five sections: emotions (8 items), body hair (5 items), weight concerns (5 items), infertility concerns (4 items), and menstrual irregularities (4 items). Each item is scored with a seven-point. Like rating system where seven represents the best situation and 1 represents the worst situation. The sum of the total points in each item per domain will be evaluated. Ultimately, the first interval values (from 1 to < 3 points) represent marked effects on health related quality of life (HRQOL); second interval values (from 3 to < 4 points) represent the marginal effect on HRQOL; third interval values (from 4 to < 5 points) represent the minimal effect on HRQOL; fourth interval (5 points) represents no effect on HRQOL.
