FYI: Dave Feldman is conducting a simple cholesterol related survey on his blog site (see link below). He is asking for the cholesterol numbers from the last pre-diet lab work and numbers from your latest cholesterol results. If you have that info handy, it is a quick survey. He put the survey up a month ago and I just noticed it. So it may not be there for very much longer should you want to participate.

I put in my numbers. When I looked up the my lab work that met the criteria that he was asking for I was amazed to see that my Total cholesterol was the exact same number for both labs. Some of the other numbers were quite different, though.

* Of note: on this March 2017 I borrowed ideas from the Feldman Protocol, eating a significant energy surplus in the days before the labs were taken - mostly from adding fat to what I was eating at the time. I also had an NMR done the same day as the standard lipid panel. It produced very similar results, confirming these numbers.
I've never taken cholesterol lowering drugs. Excluding the 2013/pre-diet lab numbers I was exercising daily (10K to 15K steps - mostly walking) year-round, including the weeks and months before each of these labs.
