Modest weight loss of 5% to 10% of initial body weight significantly improves reproductive, metabolic, and psychological features in women with PCOS.

If you have PCOS and are overweight, you do not need to reach a 'normal' BMI to see health improvements. Aim to lose just 5% to 10% of your current body weight through a moderate calorie reduction (500-1000 kcal/day) and at least 30 minutes of moderate exercise daily. This modest change can significantly improve your menstrual cycles, fertility, insulin resistance, and mood, even if you remain in the overweight category.
