From my experience, is it what works for me best when trying to cut weight. I am actually on it now, this will be my second time going through it. It fits my thought process perfectly and I will also recommend that you get those shakes in at 1 or 2 times during your underfeeding window, it does help.
I run it using a daily zig-zag style diet in terms of macros, but I feel that you have to be in tune with your average daily intake to preserve what you have to run it this way. If you are just looking for a good cut, run it a couple hundred cals under maintenance and off you go.
