You could try a transdermal fat burner, but I agree with Nitrox, the type of diet isn't going to effect where you lose fat. Generally speaking, fat is lost equally from all parts of the body. Actually you first lose fat at your extremities, so your core takes longer. Just keep a good clean below maintenance diet, know your body and how it reacts to different macronutrients, and do your cardio, but most importantly just stick with it. Like Nitrox said, there is no magic, it takes time to lose bodyfat, especially if your trying to retain muscle.
