You basically do lots of volume in a few workouts and then move to a power lifting routine at the end of the week. So your muscles are being exposed to different loads throughout the week. Could one still be successful at fat loss using HST and Lyle's UD2 just skipping his workout routine?
Of course, Lyle's approach is to deplete glycogen stores at the begining of each week. That requires high volume in the gym, which in turn requires that you use lighter weights at the begining of each week. The heavy workouts at the end of the week are to try to get some growth and/or prevent muscle loss.
I deplete and load each week on my current diet but I use HST. I haven't found that the degree of "depletion" directly corelates to the amount of fat lost each week. Instead, I have found that the volume of exercise in general, or in other words, the total amount of exercise does corelate, even if I compensate with higher carbs...
Now, Lyle's diet will work, I'm not saying anything to the contrary. I'm just saying for "me" I've benefited from keeping the weight loads heavier, and using cardio rather than reps to cut into stubborn fat. In addition, I can't eat as many carbs as he recommends without getting gastric upset... I have good results with less carbs during the repletion phase.
If you don't like cardio, go ahead and do the depleting workouts as Lyle outlines. They will work great. Plus, for some the additional training, although lighter, will still help to maintain lean mass.
On a side note, lifting light in the begning of the week and heavy at the end has been studied and was found effective for strength gains.(Rhea MR, Ball SD, Phillips WT, Burkett LN.
