Study of the effect of high protein-low carbohydrate weight loss diet with fennel supplement on androgens and anthropometric indices in overweight and obese women with polycystic ovary syndrome 2017-10-22 anticipated 64 Complete https://irct.ir/trial/11256 interventional Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Factorial, Purpose: Treatment, Randomization description: Individuals were randomly assigned to four intervention groups using a randomized table: 1-high proteine- low carohydrate diet weight loss diet with fennel, 2-high proteine- low carohydrate diet weight loss diet with placebo 3-standard weight loss diet with fennel, 4-standard weight loss diet with placebo, Blinding description: Prescribing supplement and placebo by a researcher without knowledge of its type, as well as taking it by the participants in the study without their knowledge. There is no possibility of blindness for the diet.In order to minimize bias in the intervention, one researcher randomly assigns random access to the patient in a randomized manner, without any knowledge of the patient's condition, and the other investigator who is associated with the patient, will place that person in the designated group. 3 polycystic ovary syndrome. Intervention 1: Intervention group1: Prescribe high protein- low carbohydrate weight loss diet with 2 fennel capsule per day. Intervention 2: Intervention group 2: prescribe high protein-low carbohydrate weight loss diet with 2 placebo capsule per day. Intervention 3: Control group 1: prescribe Standard weight loss diet (The amount of energy needed by each individual will be calculated using an ideal weight of BMI 22 to 23 kg / m2, and 500 calories will be deducted from the total energy required with 2 fennel capsule per day. Intervention 4: Control group 2: prescribe Standard weight loss diet with 2 pelacebo capsul per day.
