Yes, the biggest and best change I could have made to my physique is to go back to more of an eating-when-I'm-actually-hungry strategy. Imagine that. I don't eat anything near like a "normal" person would, and I still get the protein I need spread out over 4-5 meals, but force feeding 4 solid food meals plus 3 shakes a day did nothing but add 3 inches to my waist it seemed.
Over the past year I've gotten stronger and obviously leaner. Sometimes we get too fixed in the mindset of eating for size, plus I have to remember that as a natural, excess calories, protein, whatever will get turned into fat a lot quicker than other guys.
I pay more attention to nutrient timing, partitioning, glycemic indexes, etc and I only wish I had a working knowledge of such things sooner...
