Eerrmm... 10 kg is a ton and I've never heard of anyone who lost that quickly and not gained all, if not more, back. To lose weight in a normal slower fashion, I suggest the basics: drink 8 cups of water througout the day, try to eat healthier (complicated carbs, more veggies, healthy fats like olive oil, fish, avocado and the like, lean meats and so on), exercise, eat smaller portions, and so on. My particular way of losing weight involves 5 meals a day. 3 main meals of 1-2 portion (portion: size and thickness of palm) of carbs, 1-2 portions of proteins, and 1-2 veggies. 2-3 snacks that entail: 1 portion of carb or protein + 1 veggie. Good luck and remember that if one day doesn't go well on a diet, the next day will be better so don't give up!
