Cholesterol Code – Part IV : Still Correlating… in the reverse

I just attended Low Carb USA at San Diego where I shared much of the data below. And while I was interested in a possible divergence that seemed to appear at the end of May in Part III, it turned out to be more of a one-off, probably due to a higher percentage of protein and a lower percentage of fat than my usual ratio.

In upcoming Part V, I’ll be revealing some new data on a “second N” to my study. I should have that up within the week.

For now, note that the new 21 to 28 data points include a 9 day period where I once again did a total of 7 days of blood draws. Thus, we again can see this mechanism in nearly real time.

I’ll let the graphs speak for themselves…

Three Day Average of Dietary Fat vs the LDL-C in the resulting blood test. The LDL-C still tracks inversely with total fat. (-81%)

Three Day Average of Dietary Fat in the three days before blood draw vs LDL-C of the resulting test

Same blood tests, same dietary fat, but for HDL-C — which clearly tracks positively higher total fat. (65%)

Three Day Average of Dietary Fat in the three days before blood draw vs HDL-C of the resulting test

Same blood tests, same dietary fat — but with a 2 day gap in between (Days -5, -4, and -3), but for LDL-P — which tracks inversely with higher total fat. (-82%)


And finally, same blood tests, same dietary fat — but with a 2 day gap in between (Days -5, -4, and -3), but for small LDL-P — which tracks inversely with higher total fat. (-72%)


If by this point you don’t see this is a highly regulated, highly responsive network in the lipid system (at least for my N=1), then you think I’m some kind of X-Men mutant. (In which case, I dib the name, Captain Cholesterol)

But seriously…

I now have very high confidence that this regulatory pattern is likely present with virtually everyone who is fat adapted (getting the majority of their energy via fat) without an underlying metabolic condition.

It’s also quite possible this applies to those who are not fat adapted yet still with no underlying metabolic condition. For that, we’d need more study.

Thanks for sharing. I have insanely high LDL-P numbers for which I never had a point of reference. I love seeing yours and comparing them to my numbers.

I guess I need to step up my fat intake.

A pleasure to meet you in San Diego.
Looking forward to more great data from you.

I recommended watching Ken Sikaris:

He’s very engaging and has several good videos,
but you probably know most of his info.


Hello Dave

I am a 53 year old dude that has been eating low carb since February 2014. I had been morbidly obese man for much of my life (in the 300 to 400 pound range for 25+ years). I lost 250 pounds eating LCHF, reversed diabetes and hypertension – regaining my life and my health.

Since going low carb I found that I am a hyper-responder. While an obese carb eater my LDL-C was typically at or around 120. The doctor’s over the years talked statins but never prescribed them. At 5 weeks into this WOE I had my first cholesterol test. My LDL-C was 140 & TC was 205. The doctor suggested statins but I declined. In my next lipid panel a year later (March of 2015) my cholesterol had skyrocketed. LDL-C was 248 and TC had risen to 304. The doctor so didn’t believe it that she had me retested. I had similar results. She had the prescription pad out. I told her no – let me work on it. That is what I’ve been doing ever since. I’ve logged my food fairly well, made dietary tweaks along the way, and I’ve had my cholesterol measured regularly along the way. In other words, I have quite a lot of fairly good data.

Two days ago I got the results back from my latest cholesterol test. My LDL-C was 62. TC was 161. HDL-C was 89 and triglycerides were 49. I think my doctor will be pleased and finally put away that prescription pad. I still eat low carb and I don’t cheat. My current macros are around 15% carbs (50% or more of that being fiber), 25% protein, and 60% fat. My cholesterol was at its worst when I was actively losing weight, eating little fiber and had macros of 7% C, 25% P, and 68% fat. Initially I had no idea what to do about my crazy high cholesterol. I searched the web for answers and finally landed on Franziska Spritzler’s lowcarbdietitian.com website. She had experienced the same thing eating very low carb and had some very helpful suggestions in two lipid blog posts. I later found similar suggestions on dietdoctor.com.

I posted much of my lipid data and standard medical tests in a chart at the following link at lowcarber.org (scroll down to the bottom of the comments section):

1000 Days of Healthy Eating Milestone

I kept a weight loss journal on lowcarber.org as well where I documented the tweaks I was doing along the way as I tried to get my cholesterol numbers in check. I also submitted a success story to the dietdoctor.com website. Here is the link to that story:

This WOE Saved My Life

I didn’t have an NMR done during the peak of my cholesterol problem. My doctor thinks that standard lipid results are sufficient. But I did pay to have a couple of NMRs done – one while I was working on the LDL-C issue and the other 2 days ago. All the numbers were great on that first NMR except my LDL-P. Wow it was high. On this last test it was totally reversed. Here is a side-by-side of those results:

. . . . . . . . . . . . . . . . Dec . . . . . . Mar
. . . . . . . . . . . . . . . 2015 . . . . . 2017

Total Cholesterol:. . 245 .. . . . . 161
Triglycerides: . . . . . . 58 . . . . . . 49
HDL-C: .. . . . .. . . . . . 71 . . . . . . 89
LDL-C: . . . . . .. . . . . 162 . . . . . . 62

LDL-P: .. . . . . . . . . 1577 . . . . 342
Small LDL-P .. . . . . . <90 . . . . <90 (low category is 34.9)
LDL Size: . . . . . . . . 21.9 . . . 20.9 (both are Large – Pattern A)
LP-IR Score: .. . . . . . . 25 . . . . . 25 (<27 is low insulin resistance)

Needless to say I am happy with these latest results. I see my doctor in a week (or so) and I expect that she will be pleased as well. She has never had a patient lose over 200 pounds (and keep it off). I don't think she has ever had a patient resolve a cholesterol issue like this before either. Was my high LDL-C & LDL-P a danger to my health? As you have pointed out, there is no way to know. No studies exist for those of us eating low carb daily. But the fact is that it could have been unhealthy. I'm glad to have it resolved and even more glad that I was able to do it and remain low carb. Low carb is how I need to eat to stay lean and healthy.

I'd be happy to share more information with you if you are interested. If you sign up on lowcarber.org forum (free) – you can post a comment in my journal or in my milestone posts.

FYI: There is a boatload if information about how to do this WOE and how NOT to do this WOE in the forum posts at lowcarber.org. IMO – it is a data treasure trove hidden in the histories of thousands of dieters logging their journeys. It is basically an Atkins Diet site that has been around since 2002. It has had thousands of members over the years. I learned a lot from pouring over various posts and journals. I found good advice and lots of bad advice (as you would expect). Most members fail. But I found the journals of some very large people who had managed to find success. The took the weight off and have kept it off. I copied what they did and found success, too. Go figure? Diets fail – even low carb. Making this a WOE – a permanent lifestyle change – works.

Appreciate it for all your efforts that you have put in this.
Very interesting info.
