简要总结
The goal of this clinical trial is to investigate the effects of a specific dietary program on overweight or obese patients with polycystic ovary syndrome (PCOS) through a multicenter, randomized, controlled, prospective study design.
The main questions it aims to answer are:
- Does the specific dietary program increase the clinical remission rate of PCOS in overweight or obese patients?
- Does the specific dietary program improve metabolic and anthropometric outcomes in overweight or obese patients with PCOS compared with conventional intervention?
Researchers will compare the effects of a specific dietary program versus conventional intervention on clinical remission rates, metabolic outcomes, and anthropometric measures in overweight or obese patients with PCOS.
Participants will:
- Receive either a specific dietary intervention or conventional intervention for 24 weeks.
- Undergo assessments every 12 weeks throughout the study period.
