About this trial

This is an interventional treatment trial for Polycystic Ovary Syndrome focused on measuring Polycystic Ovary Syndrome, Metabolic Syndrome, Therapeutic Lifestyle Changes Diet, Pulse-Based Diet, Aerobic Exercise

Eligibility Criteria

18 Years - 35 Years (Adult)FemaleDoes not accept healthy volunteers

Inclusion Criteria:

  • Female
  • Diagnosis of PCOS in addition to insulin resistance (Homeostasis model assessment (HOMA)-insulin resistance index ≥ 2).
  • Aged 18-35 years

Exclusion Criteria:

  • Individuals that are Keto diet, vegetarian, pregnant, lactating, class 2 obese (body mass index (BMI) ≥35) current smoker, or if they have diabetes, cardiovascular, kidney, liver, or hormonal disease.
  • Individuals taking any medication or supplementation known to affect lipid, glucose, or hormone levels, and/or body weight for at least the last 3 months.
  • Any individual who has an allergy or intolerance to pulses.

Arms of the Study

Arm 2

Arm Type

Experimental

Placebo Comparator

Arm Label

Pulse-based diet

TLC diet

Arm Description

The pulse diet will include two pulse-based meals; each pulse meal will be consisted of about one cup of non-oil seed pulses, different varieties of pulses (dried beans, peas, lentils, lupine, and chickpeas) will be used. Varieties of pulses will be included and the participants will be provided with recipes and preparation ideas, which would enhance the palatability of pulses, give different taste choices, and ease the follow of the prescribed diet and encourage the participants to consume it for the target duration. The diet is isocaloric and balanced with a fixed macronutrient composition of 28% fat, 55% carbohydrate, and 17% protein.

TLC group will be provided with instructions to follow the TLC guidelines and a sample diet plan will be individualized for each participant. The healthy TLC diet will be tailored for each participant according to their energy levels in order to achieve the following amount of nutrients: less than 7% of total calories of saturated fatty acids, up to 10% of total calories of polyunsaturated fat, up to 20% of total calories of monounsaturated fat, less than 200 mg a day of cholesterol, at least 5 to 10 grams a day of soluble fiber. The diet is isocaloric and balanced with a fixed macronutrient composition of 28% fat, 55% carbohydrate, and 17% protein.

Outcomes

Primary Outcome Measures

Blood concentration of androgen hormone
Androgen hormone; testosterone will be evaluated for all participants across the 2 study arms
Ovarian volume
An experienced ultrasonographer will evaluate the ovarian volume for each ovary.
Ovulatory dysfunction
Assessed by measuring the duration of the menstrual cycle
Lipid profile
Blood Cholesterol will be evaluated for all participants across the 2 study arms
Change in fat mass
Body composition scan using InBody 120 (the body composition analyzer) will be evaluated for all participants across the 2 study arms
Physical activity
The validated Arabic short form of the International Physical Activity Questionnaire (IPAQ) will be used to evaluate physical activity of all participants. And an overall total physical activity MET-minutes/week score can be computed as: Total physical activity MET-minutes/week = sum of Total (Walking + Moderate + Vigorous) MET- minutes/week scores. ( < 4 : Low), (4-6 Moderate) and ( >6: Vigorous)
Blood pressure
In mmHg.(Systolic and Diastolic)

5. Study Description

Brief Summary
The main objective of the study is to evaluate the effectiveness of a lifestyle program for women with Polycystic Ovary Syndrome (PCOS). The investigators want to assess the efficacy of a pulse-based diet (i.e. a diet that contains lentils, chick-peas, and beans) on the clinical features, biochemical, and hormonal parameters of PCOS compared to the healthy therapeutic lifestyle changes diet.
Detailed Description
The main objective of the study is to identify the effect of pulses on a range of PCOS and metabolic syndrome features. In this parallel clinical trial, 110 (18-35 years old) women with PCOS will be recruited. Participants will be randomly assigned to either a pulse-based diet or a therapeutic lifestyle changes-based diet. The effect of a pulse-based diet on a range of reproductive and metabolic parameters will be evaluated. The results of this study are anticipated to evaluate the therapeutic merits of a pulse-based diet for women with PCOS which would influence dietary guidelines.
