As one aside on this, that Dr. Layne Norton video has drawn a lot of comments by people who declare that while CAC scores are rising dangerously in the LMHR Keto group --- exactly the opposite to what the LMHR and Keto communities predicted and wanted to see -- okay fine...it's, they now defensively claim, is the seed oils that are the cause.

Just as there is enormous volumes of data demonstrating that statins and/or lowering cholesterol naturally have a high degree of efficacy and benefit, there is a complete dearth of data showing seed oils to be the cause of much at all. Sure they're high in calories and are used in a lot of processed foods, which is bad, but the notion that some fries cooked in lard is healthier than fries cooked in canola oil has literally zero evidence. None. It has loads of counter-evidence, however.

The current seed oil boogeyman is based on absolutely nothing. But the Wellness Industry absolutely dwarfs the pharmaceutical industry, without any of the annoying oversight or governance, and there are loads of grifters that have to find the new Easy Fix.

And while I said "low carb" above as a surrogate for the carnivore/keto diet above, just to be clear, everyone should minimize simple carbs, which are often the foundation of ultra-processed foods. Unless you're highly active and burning that glucose as quickly as you digest it (which is rapid for simple carbs), those carbs are going to lead to a massive insulin spike, which is bad, and most will end up being converted into triglycerides, which is also bad. Everyone should be "low simple carbs", at least unless you're literally fuelling for a specific task.
