Who could benefit from this research

Could help

Adults with PCOS and hyperandrogenism who are willing to modify their diet and participate in health measurements and stool sample collection.

Less likely to help

Individuals without PCOS or with conditions not related to the study goals may not benefit from this intervention.

What this research studies

Women with PCOS and high androgen levels often have risk factors for heart disease, such as obesity and insulin resistance. This trial will look at whether adding resistant starch to the diet can improve blood fats, blood pressure, body composition, and gut microbes, potentially lowering cardiometabolic risk. Researchers will collect health data and stool samples to see how the gut microbiome responds and whether these changes link to heart-related factors. The goal is to find a dietary approach that could support long-term health in PCOS without relying on medications alone.

Why it matters

Potential benefit: If successful, participants may experience better cardiometabolic health and a healthier gut microbiome, contributing to lower long-term disease risk.

How similar studies have gone: Some studies in the general population show benefits of resistant starch on cardiometabolic factors, but this is a targeted PCOS-focused investigation with novel microbiome endpoints.
