no, no, noo... you dont need carbs, and you dont need to cut out fats... your body needs fats for all kinds of reasons... what you need to do is convert yourself from a sugar burning machine to a fat burning machine. cut way down on the carbs, and eat all the fat and protein you want, and train like a bastard... of course, give it a few weeks for your body to adjust. once you do, you'll never listen to these anti-low carb naysayers again, and you'll have a way of eating that will keep you powered up and satisfied for the rest of your life.
