Well it really depends on how your body handles carbs. Some people can cut with a much higher percentage of carbs. I was actually watching some videos of Layne Norton on bodybuilding.com and he was talking about how the difference between his bulk and cut is just that he cuts the carbs down. Protein and fat stay the same. And then as he gets closer to contest, he cuts the carbs more and more if he needs to. So you can just use what you have and if you aren't losing weight, just start cutting the carbs and leave the protein and fat alone.
