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
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...
4/ If fact, I was trying to get a comparable experiment (even if just for 2 weeks) with @jerryteixeira to test this part of the hypothesis 👇
(Lifters always love when I emphasize this as a "confounder" in lowering LDL -- but it makes perfect sense, IMO)
5/ @DrRagnar mentions lower insulin as relevant where observing ApoB and its association with atherosclerotic risk.
"If you have pristine metabolic health, I still think your risk is higher than somebody with the same metabolic health, but with a lower ApoB."
6/ To be sure, I'd hope the Lipid Energy Model could add to this discussion, of course.
Metabolism and ApoB are not at all mutually exclusive. I know they are often treated as discreetly separate risk factors, but I think lipid profiles are more often a consequence than a cause
7/ Prolonging the process of delivering triglycerides from ApoB lipoproteins means they will remain in circulation for longer (all else being equal), which will coincide with higher remnants and TG, alongside lower HDLc due to lower turnover.
Actively excluding those with dysfunctional lipid metabolism of genetics (ie monogenetic FH) or of acquired disease (ie Atherogenic Dyslipidemia)
Yet baseline avg LDLc levels are in the highest 99.9% of the population (~260 mg/dL)
9/ In other words, to this point we've never prospectively studied a population with extremely high LDLc/ApoB where ASCVD risk factors were low, including those around metabolism that may be directly contributing to the character and residence times of ApoB lipoproteins directly.
10/ The irony is that this was only possible due to the rise in popularity of the #keto diet.
... A diet popularized in part by @DominicDAgosti2 himself, no less.

#Me: Why would triglyceride rich LDL particles be more atherogenic than triglyceride poor LDL particles?

#Me: Couldn’t it also be possible that triglyceride rich LDL are ultimately the result of metabolic dysfunction and that better explains its association with atherosclerosis?
#Me: Is it possible that almost the entire amount of atherogenesis associated with high triglyceride rich LDL is due to dysfunctional lipid metabolism and the diseases that result in these profiles rather than the LDL particles themselves?
But I also know many people in my own family who have struggled their whole lives to lose weight and assume if they don't have this near instant drop to their goal weight like <fill in the blank success story> then they are doing it all wrong...
... I can't tell you how many times I point out truly new, record-setting successes with people I know personally -- but it's their own record, their own health journey.
But they often can't see it because they hear they "won't be hungry anymore on <fill in blank diet>"...
If you've followed me a while, you know I try to avoid the "diet debates" (tho not always successfully)
However, I have been getting a high frequency of DMs/messages/calls regarding DD's new endeavor for a #lowcarb alternative
2/ Let me first start off by saying I don't think any diet is inherently superior to all others.
I *do* think the #lowcarb diet is under-utilized for populations that can uniquely benefit from it.
However, I also believe most of us have many more options than is often assumed.
3/ Moreover, I consider @DietDoctor's long history of providing a "one stop shop" platform for all things #lowcarb/#keto with high quality guides, videos, and tools to be without equal.
It made it extremely easy to refer everyone in DD's direction, particularly beginners.
