Dieting alone is a waste of time, it needs to be combined with excercise. Compile a strict regime of excercise and healthy eating. Join a gym, take up some competitive sport, badminton, tennis etc and cut out all the rubbish from your diet. Chocolate, fizzy drinks, sugar and dairy stuff. If you are peckish, snack on fruit and raw veg. Your weight will fall off. Just eating less and sitting around waiting for the scales to say what you want them to say aint working.
