Just this morning I was watching a YouTube video with Peter Attia and Layne Norton. Attia asked Norton for 3 things related to nutrition that he has changed his mind about in the last few years and which have led him to a change in coaching advice or protocols. Norton said he no longer aligns with people who discount the risks of LDL and argue for the LDL/HDL ratio instead. Layne recognizes the linear relationship between LDL and heart attack risk. Layne also said he’s on statins. Which blew my mind. Given his age and PhD he’d still rather eat meat — against his own concerns for LDL — and take a pharmaceutical instead of directly addressing the source of his cholesterol issues. Relevant because of the prevalence of dairy and meat as the source of cholesterol in the modern diet. The video: https://youtu.be/jmYeMmUjBrE https://youtu.be/jmYeMmUjBrE

Correct me if I'm wrong, but dietary cholesterol is not main driver of serum cholesterol, right? Very easy to eat a vegan diet and have very high cholesterol. And vice-versa.

  Lots of lifestyle issues with serum cholesterol, but per the Mayo clinic plenty of dietary sources contribute to high serum cholesterol too, including meat and dairy: https://www.mayoclinic.org/diseases-conditions/high-blood-cholesterol/in-depth/reduce-cholesterol/art-20045935 https://www.mayoclinic.org/diseases-conditions/high-blood-ch... Presumably Norton isn’t having issues with a lack of exercise or high body fat.

I listened to the same podcast, and your making a huge jump in logic from your second to third paragraph with a lot of assumptions that weren’t discussed there.

  He's written a book, documents his lifting on Youtube, and has been tweeting his own very opinionated positions on nutrition and food intake for many years. Maybe there's a jump on my part, but "huge jump in logic"?

Cholesterol is hardly a good predictor of heart attack or heart disease. I think it ranks 8th? Less than 10%. Over 75% risk factors Are, in descending order: type 2 diabetes, metabolic syndrome, HTN, obesity, smoking, high triglycerides. https://jamanetwork.com/journals/jamacardiology/article-abstract/2775559 https://jamanetwork.com/journals/jamacardiology/article-abst...

Is there anything that could take meat's place? Presumably we wouldn't want to just eat a lot more carbs and instead eat something that's got a similar amount of protein (the thing that seems to make meat nutritionally unique). Legumes of all kinds seem to give me and a lot of other folks digestive issues.

  Fish? I think the issue is high cholesterol, high fat meat.
