Hi, firstly you need to talk to a doctor and a dietitian to know your health conditions and target for weight loss, fat loss. Drinking 3 liters of water everyday is a must. You have managed 2 liters which is great so now have 1 more liter everyday. Take planned diets which suit your body and eating patterns and schedule. So they will help in achieving results. You can mail us your details about your height, exercise patterns, eating patterns, sleep patterns and we can mail you diet plans if you want. So we can achieve results that you want. Also once you start reducing weight and have healthy eating patterns your PCOS also will start healing.
