First of all make sure that your target intake is suitable for someone of your age, size and activity level. Keep a 700 cal deficit between your total burn and your calorie intake... no higher. And second, make sure that you're accurately counting your calorie-intake, weighing and measuring portions rather than guessing.
If you've been on reduced calories for more than six weeks you could benefit from a day or two soon when you get your full energy needs .... 'total burn' in CC terms. Obviously, still choose good foods when you do this. By occasionally having a day where you get your full energy needs (rather than small increases/decreases) you can find your body starts to use energy a little quicker.
You could change your diet around in terms of your food choices. If you find you're eating the same things too often, it can help if you deliberately include new foods and new recipes.
Good luck
Hi, I found this article and it helped me understand plateaus better. I hope it helps you too.

try switching up your exercise... if you are normally a runner, try some cycling or swimming. make sure your work-outs are challenging. weight-training is also a GREAT way to build muscle and burn fat.
check out hiit (high intensity interval training), to REALLY burn up those calories fast.
DON'T GIVE UP!!! ;)
