Energy Levels and Individualized Matching The dietary intervention includes three energy levels: 1200 kcal, 1400 kcal, and 1600 kcal.

The nutrition team will adjust the energy level and dietary plan every 4 weeks based on weight changes and metabolic feedback, with the intervention continuing for 24 weeks.\n2. Nutritional Composition and Base Formula Design The plan consists of 1000 kcal for lunch and dinner daily, with a focus on high protein (\\>80g) and high fiber (\\>30g) to support weight management and improve metabolic status. This intervention will continue for 24 weeks.\n3. Food Ingredients and Intervention Frequency The intervention uses natural ingredients, with at least 12 types of foods daily.

Does the specific dietary program improve metabolic and anthropometric outcomes in overweight or obese patients with PCOS compared with conventional intervention?\n\nResearchers will compare the effects of a specific dietary program versus conventional intervention on clinical remission rates, metabolic outcomes, and anthropometric measures in overweight or obese patients with PCOS.\n\nParticipants will:\n\n1.
