On this day in 2015 I received a lab result that would alter the course of my life.

2/ With that first test I was overcome with shock and curiosity — much more former than the latter.
I wanted to get a repeat test to confirm this wasn’t a lab error.
I wasn’t ready to give up #keto, but I was miserable enough that I ate considerably less.

3/ At the same time I learned as much as I could about Lipidology - which focuses on how the body moves lipids (like cholesterol) in the blood.
And to my surprise, this system is already very familiar to me as a software engineer given it is a distributed object network.

2/8 The #LMHRpaper was our first describing the #LMHR phenotype
- #LDL #Cholesterol of 200 or higher
- #HDL #Cholesterol of 80 mg or higher
and
- #Triglycerides of 70 mg or lower
Which is actually common for lean, very folks on #lowcarb/#keto folks. doi.org/10.1093/cdn/nz…

3/8 Our second paper brings a case report on a single #LMHR with extremely high #LDLc (~500 mg/dL) for 2.5 years, their eating patterns, and current CT angiography.

1/ Alright, let's chat the #NHANES (IV)
As usual, I'll give my caveats this is back-of-the-envelope on data I wrangled via CDC on this expansive dataset -- and it's associational, ofc (observational)
So what are the lipids like for those who live to 100yr in NHANES?

2/ Remember, these aren't the lipid levels taken *at* age 100+, it's what their levels where at the time of examination 15-20 years prior.
This is very relevant when considering reverse causality given this extreme gap in time for all who were reaching centenarian status.

3/ First up -- #LDL #Cholesterol.
Yes, 73% of you correctly guessed 130mg/dL is the mean average for these 32 individuals (lipids taken age 85 or earlier).
LDL mean average: 130 mg/dL
0% 25% 50% 75% 100%
72.0 102.5 126.0 154.0 215.0

1/4 Back-of-the-envelope:
There are now 32 NHANES participants with lipids & mortality data who have lived to at least age 100 (age + followup > 100yr.), thus earning the designation of "centenarian"
What was mean avg #LDL-C for this group from their bloodwork 15-20yrs prior?

Let's review quickly all of the science I've come across in the past week that applies to high-fat ketogenic carnivore type diets.
I'll post the link, an image of the abstract, the title, and some hashtags on each one.

This is actually relevant timing as we are rapidly approaching the #LMHRstudy. sciencedirect.com/science/articl…

2/ If you didn't already know, "Lean Mass Hyper-responders" (#LMHRs) would be considered hypercholesterolemic, with this resulting from being very low carb (typically #keto), and are often lean and/or athletic.

3/ Setting aside why this population exhibits this (see #LipidEnergyModel for more), the most important question is whether they are at risk.
This MR study builds on the existing conventional expectation that they are, and no less in a dose-dependent manner...

➡️La #enfermedad #cardiovascular es la principal causa de muerte en la población general. Está asociada a decenas de patologías, entre ellas, #diabetes, #obesidad, #tabaquismo, enfermedades autoinmunes, etc; y la que veremos hoy: las dislipemias o enfermedades del colesterol.
➡️Las #Dislipemias son enfermedades causadas por alguna alteración en el metabolismo de los lípidos (colesterol y triglicéridos).
Pueden ser primarias-de causa genética, adquiridas-por determinados hábitos como 🍔🚬 y secundarias-asociadas a otras enfermedades.

1/ For a very layperson-friendly video on conventional view of #LDL / #HDL #Cholesterol, and #ApoB, I highly recommend this one from @NutritionMadeS3
It's very visual and IMO fairly true to the more specific position of mainstream lipidology...

2/ Love his opening: "why is this topic so confusing? well, for starters scientists are horrible at coming up with names...there's LDL...and LDL cholesterol and they're different things....but a lot of people call them both LDL....and then there's HDL, VLDL..." (trails off)
3/ He's 100% right. It's why it's so hard to convert this for the lay audience. Lipidology could use a terminology upgrade.
For example, how did "Chylomicrons" manage to get a special exception to the "-DL" acronym party? (Only fellow lipophiles will get that joke... 😐)

3/ I began learning everything I could about Lipidology and the system that moves #cholesterol around in our body. To my surprise, it has many structural things in common with a network (a very advanced one, mind you), but soon I was manipulating my own lipid levels easily.
1/ My presentation to @stanford on the Lipid Energy Model is now up at my channel.
It was a great honor to be invited and discuss my research, experiments, and this hypothesis in depth.
Lots of discussion on #LDL #HDL #Cholesterol #ApoB and #LipidTriad

2/ For many of you who have followed my work for a while, this will feel like review. But this presentation challenged me to tie everything together as best I could for a non-#keto/#lchf audience at a university level. Given the feedback /retention, it appears to have gone well..
3/ Of course, there's quite a lot that it *not* covered, and indeed I wanted to squeeze a bit more into it. Sometimes I wish I could summarize the energy delivery throughput and cross my fingers everyone at a certain level will get it. But that's been the biggest challenge...
1/ I consider #HDL extremely relevant, yes. It’s one of the existing five criteria for metabolic syndrome and one of the three for atherogenic dyslipidemia. ncbi.nlm.nih.gov/pmc/articles/P…
2/ It’s one of my three target markers for the #LCCholesterolChallenge (which is about to turn two years old next week). cholesterolcode.com/lccholesterolc…

Extracellular acidity in atherosclerosis is one of my favorite topics, so I'm really, really excited about this study (2/15)
The authors show that some individuals have carotid atherosclerotic lesions that have an acidic pH. They show this is due to activation of Na+-H+ exchanger in macrophages, which leads to extrusion of H+ and extracellular acidification (3/15)
