Sorry —my comment came off wrong.  
It sounds like you know quite a bit on the topic and I assumed something based on the pre load carb comment is all.  I disagree with that approach is all. I don’t know enough about your specific situation to weigh in.  You said its not sustainable.  How so? Whats making you think that? 

 My energy levels were at an all time low. I could barely push through a workout. So I adjusted. More carbs, less fat. My body likes it. 

I'd rather use fat as my primary source of fuel, but I'm going with this method for a few more months while cutting. I have to listen to my body here.
