Summary

This trial will compare the effects of TRE vs CR on body weight, androgen markers, inflammatory markers and insulin sensitivity in women with PCOS.

Who is the study for?
This trial is for women aged 18-40 with obesity and PCOS, diagnosed by the Rotterdam criteria. Participants should have a BMI between 25-50 kg/m2 and not be postmenopausal or have diabetes, eating disorders, or recent use of certain medications that affect weight and hormones. Smokers, pregnant women, high-intensity athletes, and those without Wi-Fi are excluded.
What is being tested?
The study compares three approaches over six months: (1) Time Restricted Eating (TRE), where participants eat freely from 1 pm to 7 pm but fast at other times; (2) Calorie Restriction (CR), reducing daily calorie intake by 25%; and (3) no specific diet control. It aims to see which method best improves body weight, hormonal balance, inflammation levels, and insulin sensitivity in PCOS.
What are the potential side effects?
Potential side effects may include hunger during fasting periods for TRE group members or feelings of restriction/fatigue due to reduced calorie intake in the CR group. The control group might not experience these issues as there are no dietary changes.
