What's your BMR? What's your calorie deficit each day? How much of your lean mass is AAS induced?
I've had a lot of success with a diet that is about the same ratio 40/40/20. I seem to have good results with hitting it hard like two or three days with reduced calories combined with extended cardio (I can shoot basketball forever) and then upping the calories to BMR and no cardio for three days. Seems to keep my body from assimilating to the calorie deficit. My mass is AAS induced so I don't cut unless I'm on cycle (learned the hard way).
