Just read through most of the advice given, but I do not see anything that will really help you or answer your question.
So here I go...
First, take a look at my diet

It was made for me by a professional bodybuilder, one who had been to the Ms Olympia 7 times. This was made specifically for me, but it will give you an idea on what to do. This is a diet designed to get me down to 6% BF in 14 weeks.
Next, cardio will eat away at your muscle, do not do cardio, If you work up a sweat your working to hard. The best way is, first thing in the morning, BEFORE breakfast, walk on the treadmill for 60 minutes, not a real fast walk, just a normal one. you want to get your heart rate up a little, but not so much where you sweat or get tired. This will burn off fat fast and limit the amount of muscle you burn.
