How to lose weight but maintain muscle? -

Well, basically, I want to lose some weight but maintain my muscles at the same time. I m probably heavier than what I look like because I have a lot of muscles from karate, but there is a bit of flabby skin around my body that I want to tone up. Is there a way to get rid of this extra fat without losing any of my muscle mass? Also, will I lose that much of my hips/boobs? Thanks. :)

well u have to do more cardio to burn the fatalso u need to take alot of whey protein so it stores in your musclesand also some glutamine powder.. that way the muscles do not break down
