The best diet for PCOS to lose weight focuses on managing insulin levels and promoting overall health. Prioritize whole, unprocessed foods like lean proteins, vegetables, fruits, and whole grains. Incorporate healthy fats from sources like avocados, nuts, and olive oil. Limit refined carbohydrates, sugary foods, and processed snacks to help stabilize blood sugar levels. High-fiber foods, such as legumes and leafy greens, can improve digestion and support hormonal balance. Consider smaller, frequent meals to manage hunger and energy levels. Additionally, staying hydrated and reducing caffeine and alcohol intake can enhance results. A balanced, sustainable diet combined with exercise is key.
