Protein and Polycystic Ovary Syndrome (PCOS) Study

This study is looking at how different dietary patterns affect women with Polycystic Ovary Syndrome (PCOS), a common hormonal condition. Researchers want to see if a diet with more protein, or simply a calorie-restricted diet, can help improve body composition. You might be able to join if you are a woman between 18 and 50 years old with a confirmed PCOS diagnosis and a BMI between 18.5 and 35. The main goal is to measure changes in lean body mass (muscle and bone) after 16 weeks. The study is currently unclear about its recruitment status.

Study design
This interventional study plans to enroll 60 women with PCOS. Participants will follow either a higher protein diet or a general calorie-restricted diet.
What's involved
Participants will follow a specific dietary pattern for 16 weeks. Lean body mass will be measured at the beginning and end of this period.
Compensation
Not stated in the trial record.
Follow-up
Participants are followed for 16 weeks, which is the duration of the dietary intervention.
