I started paleo about 3 years ago. I'm in my late 20's and am fairy active w/ 12% body fat.
I've been even more paleo in the last year (rendering my own pastured pork fat for lard, eating lots of coconut fat instead of olive oil), eating lots of fattier cuts of grassfed beef. I've also minimized my grain, alcohol and sugar intake in a big way. Dairy (mostly grassfed) is still in the picture.
My weight and body comp haven't changed at all. I just feel less congested from eliminating wheat and now have more stable blood sugar (minimal hunger swings).
Out of curiousity, I got some bloodwork done. Everything else was the same from a year ago (HDL=50, TG=80) but my TC jumped 80 points as did my LDL (I doubt they measure LDL directly but the Friedwald and Iranian calculations give similar LDL of ~150). I had expected HDL to jump and LDL to go down further!
Of course I have no idea what the particle size of this LDL is but I could spend $70 on that test. Folks like KGH would probably just say "who cares" since I'm not consuming wheat or fructose thus avoiding oxidized and small LDL. I could be all large and fluffy...
Also, I ate a pound of uncured Niman bacon before starting my 12 overnight hour fast. Could that have thrown anything off?

CHolesterol tests can vary as much as 50% from one lab to another. There is also a large variation from one day to another. I wouldn't judge much on one test. Also, since this was not a direct measure, you may actually have a smaller number of LDL particles but if they are lighter and fluffier, they will skew your test to make it look like you have more. Because they don't know particle size, so they just go by volume and then guess the number of particles. Also, if you look at the research, low cholesterol is bad for you. LDL is directly involved in actively killing germs in your bloodstream and low cholesterol is linked with increased levels of cancer. Some people who go paleo find their not direct measure LDL to go up and some find it to go down. But most (all I have heard) find that their HDL goes up. So I am not really surprised by your findings. I'd say you sound like you are healthy and in good shape. After all I've learned, if I went today to the doctor and he/she said my LDL has gone up on paleo, I would not care. I no longer think higher LDL is a problem in itself. In fact, I'd be more worried if my cholesterol got too low.

Particle size is important. So are the ratios of the cholesterol numbers. Here's what to use:
Total/HDL: (ideal = 5 or below)
Trig/HDL: (ideal = 2 or below)
LDL/HDL: (ideal = 4.3 or below)
And don't forget that if your trigs are below 100, then your LDL, (which is calculated, not actually measured) wil be off. US labs use the Friedewald equation. Since your trigs are below 100, they should use the Iranian method. Here's a link to a online calculator: http://homepages.slingshot.co.nz/~geoff36/LDL_mg.htm
Hope that helps!
