Feasibility Effects of a Low-GI, High-fibre Diet in PCOS: a Prospective Cohort Study in Remote Yunnan

This study aims to observe the effects of a 6-month, culturally-adapted low glycemic index-high fiber (LGI-HF) dietary on IR, androgen levels, and menstrual regularity among women with PCOS in remote areas of Yunnan Province. We hypothesize that a nutritional strategy designed for high-carbohydrate dietary habits while balancing feasibility and adherence can significantly improve patients' metabolic and reproductive parameters, thereby providing practical evidence-based guidance for long-term PCOS management in resource-limited settings
