I would suggest that you increase your protein intake while reducing the amount of carbs to start. It is also a myth that muscle weighs more than fat. A pound is equal to a pound. The reality is that muscle is more dense than fat. This means that a pound of muscle takes up less space than does a pound of fat. Therefore, if a 200 lb man has a higher fat % than another 200 lb man (assuming similar height), he will look bigger.
I would also suggest that you focus weight training to lighter weights used and higher reps. With cardio, I suggest that you wear a heart monitor and track your heart rate. Try to keep it close to the 80% limit for your age.
Hope this helps and best of luck!!
