There are lots of questions and information on cholesterol here, but I didn't find a question on this exact subject. I apologize I missed something.
I'm wondering how much people have seen their TC and/or LDL change based on the following things:
1) From day-to-day or week-to week? Most of us have labs done every few months or so but, if you've ever had them a few days or few weeks apart for any reason, how much variation have you found in the short run?
2) From calculated to measured cholesterol? I've read (maybe on this forum) about people's LDL changing hugely when they asked their LDL to be measured rather than calculated. Just wondering how much folks here have seen a substantial change?
Thanks for sharing your experience.

It depends on the type of fat you eat. If most of it is just fat attached to meat, then it will likely go up slightly. If you eat a lot of myristic (and to a lesser extent palmitic) fatty acids via butter/coconut consumption, you'll see a jump in both HDL and LDL. I was eating massive amounts of butter in everything and my total cholesterol went from under 200 to 391. I'm getting it tested again in about a week, so I'll report back with an update.
Now, as to whether or not this jump is actually clinically significant, that's anyone's guess. I've decided to remove most dairy fat from my diet and replace it with fat from the ruminants themselves, but it may be that sky-high LDL is a marker for the type of fat you eat, not for a particular morbidity.
Edit: To answer the rest of your question, the rapidity with which it changes in a healthy person is quite high. For a sick person whose LDL is fighting a losing battle trying to repair inflamed arteries etc., the cholesterol content of lipoproteins will likely remain upregulated, but for you or I tinkering with our diet, we'll see rapid swings. If you read scientific papers/clinical studies, they'll have a dramatic change upward in LDL for example on a high myristic acid diet and then a brief "washout period" where it returns to "normal" before they put that individual on one of the other diets.
What this means for us is that if you had to take a cholesterol test for insurance purposes or something where some idiot is going to misinterpret the results and use it to screw you over financially, then you could just cut out all butter/coconut, reduce fat in general, increase soluble fiber for a couple weeks leading up to the test and then just go back to your normal diet afterward. I would expect a profound difference.

I actually got tested on two consecutive days. Thursday 8.00am fasting test (following a week of over-consumption of saturated fats) 5.2 (total Uk scale). And a non fasting test Friday 8.00am (following a near zero saturated fat day) 3.99 (total)/ 1.57 HDL).
Suggests a huge variation and also calls into question the accuracy of different types of testing.

The first set of numbers is from 2009 but those are the same numbers I usually got annually on the SAD. The second set is from a lipid panel done the day after I completed my first Whole 50:
Cholesterol - 222 --> 217 HDL - 71 --> 105 Chol, non HDL - 151 --> 112 Triglyceride - 82 --> 30 LDL - 135 --> 106
In summary - Overall cholesterol DOWN (5) HDL UP (34) Non HDL, chol DOWN (39) Triglyceride DOWN (52) LDL DOWN (29)
During the Whole 50, though, I ate mainly lean meats and got my fat from coconut milk and avocados. I also ate no whole eggs. I really don't know how different these numbers would look if I'd relied more on fatty meats and eaten whole eggs.

Hubby's readings all rose slightly from last year, and I haven't been to the doc yet.

I had my last tests in July, a few months on paleo, but still with gluten then. My LDL went slightly up, HDL went very strongly up, by 40points or so. Trigliceryds went down to 37, I think from around 90, if I remember correctly. I should do a check up soon, to see changes since going completely gluten-free in July.
