Appetite Response to Meals With Different Protein Sources in Women With PCOS

This study is looking at how different protein sources affect appetite in women with Polycystic Ovary Syndrome (PCOS), a common hormone disorder. Researchers want to understand if meals with animal protein impact your body's energy use differently than other protein sources. You would be given a meal containing animal protein and your body's response would be measured for 240 minutes (4 hours) afterward. The study aims to enroll 30 women between 18 and 50 years old who have a confirmed PCOS diagnosis and a BMI between 18.5 and 35. You also need to be willing to eat both plant- and animal-based protein meals.

Study design
This is an interventional study planning to enroll 30 participants. It will compare metabolic responses to different protein sources.
What's involved
You will consume a meal challenge and have your meal response measured over 240 minutes (4 hours) at specific time points.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for 240 minutes (4 hours) after the meal challenge.
