Gammite,
If you have a workout you are doing now that is working for you again CKD may not be for you. CKD includes workouts and generally looks like weekend carb-up, then either a Monday full-body workout or a Mon/Tues upper/lower body split. You might be able to do some aerobics on Wed/Thurs and then on Friday you do some sort of depletion workout (followed by a boatload of carbs). TKD or some form of modified lowcarb diet should provide you the energy to do your workouts. Because of the limits of the CKD workouts the increase of lean muscle is only a secondary goal and since lean muscle burns more calories theoretically the weight loss should be better (which is why, Big Dog, many lifters use other diets to drop weight and then use CKD to get rid of the final stubborn fat). But, see how you feel with your workouts and tune your carbs as needed.
