What are your stats? You can get shredded on a high carb diet/low fat, low carb/high fat diet, or a balanced diet it doesnt really matter. One or the other may be more ideal for you personally, but whats best is whatever you like the most and can stick with. The trick to losing fat and not muscle is find your maintenance cals, subtract 300, then shoot for 40% of your cals from protein, divide the rest between carbs and fat. I like to utilize BCAA's in high doses around my workouts as well when dieting. I almost always do low carb diets, but I have gotten well under 10% using all methods. Funny thing was, the most peeled I have ever been, I was eating 400 carbs a day!! Too bad I ate way too low fat and cholesterol for too long and it severely hurt my test levels! Oh well, live and learn! Also, HIIT style cardio will be your best friend. Good luck!
