1/🧵 I'm definitely a fan of both @DominicDAgosti2 and @DrRagnar (obviously), so I was excited to see them chatting about #lipids, #LMHRs, and Dom's consideration of increasing carbs to lower his #ApoB
If no one minds, I'd like to add some thoughts...

2/ First -- I'm extremely excited to share @DominicDAgosti2 may be the most notable N=1 I've waited for regarding #ResistanceTraining change & #LDL/#ApoB in a #ketogenetic context
Those who've followed me for a while know exactly what I'm talking about...
Those who've followed me for a while know exactly what I'm talking about...
3/ When chatting with Dom in SD last year for dinner, he mentioned focusing less on maintaining such a sizable muscle mass as he typically does, and I predicted he'd likely see his LDL/ApoB as considerably higher with this change if still #keto. This podcast appears to confirm...
1/2 Example 1:
🚬 Imagine if the average person from the moment they're born were taught to be 2 pack a day smoker.
⛔️ Now imagine a fraction were born into families that were 0 pack a day smokers.
Would we expect that latter group to have greater longevity than the former?

2/2 Example 2:
Now imagine most people averaged 100 #LDL cholesterol over their lifetime.
But a fraction were born with a genetic mutation that kept their average at 20.

If genetically low LDL/ApoB had universally a net benefit -- this would be strong evidence that indeed this particle is pathogenic -- which is to say, disease-causing overall (not just atherogenic)
But does existing genetic data support this hypothesis? Is there clear longevity?

A couple notes...
1️⃣ Many assume the higher ACM associated with LDL-C is due to "reverse causality". It's a hypothesis, to be sure, but one I think worth exploring.
Thus, it would have been ideal of the authors tried at least one or more analyses censoring 2-3 years.

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.

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.

“After 12 weeks, the mice fed conventional soybean oil had much lower levels of VLDL and LDL cholesterol… compared to the mice fed lots of saturated fat. However, to the researchers’ surprise, the mice on those two diets had the same amount of plaque buildup in their arteries…”
Naturally, I’m especially interested in how much impact this diet had on resulting oxidative potential of newly synthesized lipoproteins and how much (or how little) of these reduced Lp-X levels could be a result of scavenger receptor removal in particular.

1/ Yes, the topic of a "hyper-response" with high #LDL #Cholesterol (LDLc) on #keto has been coming up a lot this summer, particularly for #LMHRs -- and that's a good thing. More discussion and research desired!
I'll try to unpack the key differences in 3 standing hypotheses...

2/ Conventional: higher LDLc "hyper-response" (HR) mainly due to higher consumption of saturated fat (SF)
@DrNadolsky hypothesis: HR due to higher SF, but also genetics
Me: HR affected by many things, but generally more influenced by Lipid Energy Model (LEM) than SF or genetics

Me: HR affected by many things, but generally more influenced by Lipid Energy Model (LEM) than SF or genetics
3/ Starting with a few key influences we all agree on...
These things likely have a significant detectable increase on LDL compared to reverse:
1) Swapping unsaturated fat with SF
2) Reducing fiber
3) Less resistance training

2/ He's already conceded he's left out all the context on aiming for #LMHR profile, the relevance of RER, and the #LEM (so no need for people to keep pinging me on the IG video). I've chatted with him privately and we'll leave it at that. 👍
3/ However -- this actually affords us a huge new opportunity.
@DrNadolsky's claim isn't just his own, it's just about everyone else's outside the low carb community.
Simply stated: high #LDL #cholesterol seen in #LMHRs is predominantly due to high consumption of saturated fat.

1/ First off, this thread is long with lots of nuance.
But here’s the bottom line:
👉 I dropped my #LDL by over 400 mg/dL

Add in some carbs.
This shouldn’t be a news flash for anyone following our work on the Lipid Energy Model

3/ I’m an example of an LMHR that eats a relatively low saturated fat diet at baseline. Even when >80% of my fat intake is MUFA/PUFA, my LDL can run >500. Thus, it’s not simply the sat fat. Even when fiber intake has been >30g with net carbs <30g, my LDL can easily run >350
1/ I'd love to take an opportunity to expand on this important topic, and if I may, suggest something important to watch for with some newly emerging data.
To @MichaelMindrum point, I too believe the #ApoB will demonstrate higher association with #ASCVD than #LDL #Cholesterol..

2/ But to be sure, ApoB can be best represented as:
(1) Non-LDL ApoB lipoproteins
- and -
(2) LDL ApoB lipoproteins
The first category is predominantly chylomicrons, VLDL, and IDL -- which associate very highly with ASCVD.

3/ You can think of category (1) as "Triglyceride Rich Lipoproteins" (TRL, aka "remnants") and category (2) as "Triglyceride Poor Lipoproteins" (TPL)
The population of #LMHRs have extremely high levels of ApoB. But this pattern is a mix of very *low* TRL and very high TPL.

9) Many risk factors modulate the propensity of LDL-C to traverse the endothelium and enter the arterial intima. See 🔓academic.oup.com/eurheartj/arti….
10) It now appears that the passage of #LDL into the #intima is not a merely passive process whereby the concentration in blood & the permeability of the endothelium determine LDL accumulation.
11) It’s #Transcytosis (an active process), through a vesicular pathway involving #caveolae, scavenger receptors (#SRB1) and activin like receptor kinase 1 (#ALK1). Hence for a given blood level of LDL-C the amount of atherosclerosis is variable.
