i have always found sticking to 1200 calories and plenty of water and exercise did it for me. it can take a while to lose alot of weight but at least you know your doing it the right way and its going to stay off. try and cut out as much fat as you can also. eating things such as salads and having sweetner in your tea instead of sugar should also help you on your way. your know yourself weather something is fatty or not. i also try to stay away from high carb foods (bread pasta rice) unless i am going to the gym that day or i will only have it in small amounts. carbs are very filling but i find im not satisfied as you can only have small portions so replace it with something a little more biteable. hope this helps. x
