It depends on how quickly you want results. If you want to smoothly ease into fat loss over a long period of time, keep going your way with a slight decrease in carbohydrate and cardio in a fat burning zone (120-150 beats per min).

If you want quick (I'm talking in like two weeks), snap your calories in half, drop the carbs to below 50, and do fasted cardio in the morning with 200 mg of caffeine for as long as you can stand it. It'll be grueling painful, but it works real quick.
