Him1, we can agree to disagree here, but I'm gaining muscle quite rapidly with no postworkout carbs 5 out of my 6 workouts every week. One of them happens to fall within my carb up so, natutally it gets carbs. While, I'm not going to argue and try to convince others that low carbs diets are ideal for gaining lbm, I do know from first hand experience that one can not only avoid loosing muscle w/o post workout carbs, but can GAIN muscle without them.
bilat, if you are doing a ckd, my advice is to NOT eat carbs pre, mid or post workout. You'll get them during your carbup phase.
