Mind if I ask - how did this affect your LDL/HDL and insulin sensitivity or other parameters?
I'm really not sure. My prior medical issues (before diet changes) keep me in a doctor's office for routine follow-up checks at least once every couple of months. Those visits almost always include blood tests and full lab reports. Other than the issues related to my prior medical condition, my other levels are always in the normal range -- including cholesterol and glucose levels.
While my overall average is about 1000 calories a day, and I avoid meat and processed foods (especially processed foods), I will go "off diet" once or twice in a two-week period. Otherwise, I stay primarily on target.
