ately all I have been hearing people ask about is fat loss, so I thought I would jot down some notes on Cyclical Ketogenic Diet or CKD for short. This is a diet that I have used on and off for several years. A lot of people call it the bodybuilders' diet. What they mean by that is you lose fat but keep lean muscle mass. With traditional low fat diets you tend to lose muscle mass you do not with this one. There are a couple down sides to this diet for me. The first being I can not gain mass on it I can loss fat and maintain the lean muscle I do have I just can not gain any more lean muscle. The second problem I have on this diet is the adjustment phase, the first week I am really sluggish.
