Since the Keto Diet prevents seizures, they are researching why. This test seems to show It displaces brain glucose processing.

It does this by improving memory processing and shunting some portion of spatial reasoning to the emotional processing centers. They couldn't see this changed any behaviors.

This isn't a massive void, and this isn't about saving weight and building materials...In fact it makes things more complex, and requires giant chevron stones. And also since this feature is at the edge of the outer shell of the pyramid, there isn't much weight above this structure anyway. And the descending corridor below already has effective lintel stones protecting it anyway. So there isn't much weight above, and it doesn't seem to be designed to protect anything below as far as weight goes.

As far as repeated structures go, I personally agree that the corbelled grand gallery does play a role in moving/lifting the giant granite blocks for the "King's Chamber", but that section is higher up than this newly imaged "front door passage". And there are no giant granite stones involved with this level anyway (that we know of).

Not sure how you can disagree, the terms themselves have to be subjective since they are, by definition, relative. Things that your average boomer would consider left would likely be considered right by your average gen Z. Same with a European vs. an American.

With regards to post Covid data, it will be a while before we get reliable information since in Left leaning circles people aren’t allowed to express reservations about vaccine openly like in right leaning circles and masks.

I not saying there isn’t more conservative centric info on Fb, it’s mostly a boomer platform after all, I just have concerns with their methodology given I did this work professionally and given what was presented in the article I think what they have done has the potential to be flawed.

I know there is also a tendency to put all Covid misinformed into the right/Republican bucket whatever the source. In 2020 a lot of the Covid misinformation was coming from sources that we suspected were PRC and then they spread across all political spectrums. It wasn’t until post 2020 election that it really polarized that questioning the status quo on Covid was considered right wing. Remember the democratic presidential debates when the candidates called the safety of the Covid vaccine into question?

Then in 2021 I remember neighbors in SF acting like I was crazy for discussing the danish, German, and Israel data that suggested 6-8 week between vaccine doses was safer for young men.

That all depends which metric you use to determine "misinformation". Example, as a constitutionalist, I've said it's unlawful to force the population into vaccines, which at the time was "misinformation"...but several lawsuits later and what appears to be many more to come, it turns out I was right. Fyi: I don't really care about being right, I care about our freedom and I love my fellow man. And since Ive studied the constitution quite a bit more than the average Joe, I can confidently make such claims ahead of SCOTUS, and feel that I'm obliged to let others know.

Abstract:

Purpose

Ketogenic diet (KD) is recommended to avoid intense [18F]FDG myocardial physiologic uptake in PET imaging. Neuroprotective and anti-seizure effects of KD have been suggested, but their mechanisms remain to be elucidated. This [18F]FDG PET study aims to evaluate the effect of KD on glucose brain metabolism.

Method

Subjects who underwent KD prior to whole-body and brain [18F]FDG PET between January 2019 and December 2020 in our department for suspected endocarditis were retrospectively included. Myocardial glucose suppression (MGS) on whole-body PET was analyzed. Patients with brain abnormalities were excluded. Thirty-four subjects with MGS (mean age: 61.8 ± 17.2 years) were included in the KD population, and 14 subjects without MGS were considered for a partial KD group (mean age: 62.3 ± 15.1 years). Brain SUVmax was first compared between these two KD groups to determine possible global uptake difference. Semiquantitative voxel-based intergroup analyses were secondarily performed to determine possible inter-regional differences by comparing KD groups with and without MGS, separately, to 27 healthy subjects fasting for at least 6 h (mean age of 62.4 ± 10.9 years), and KD groups between them (p-voxel < 0.001, and p-cluster < 0.05, FWE-corrected).

Results

A 20% lower brain SUVmax was found in subjects under KD with MGS in comparison to those without MGS (Student’s t-test, p = 0.02). Whole-brain voxel-based intergroup analysis revealed that patients under KD with and without MGS had relative hypermetabolism of limbic regions including medial temporal cortices and cerebellum lobes and relative hypometabolism of bilateral posterior regions (occipital), without significant difference between them.

Conclusion

KD globally reduces brain glucose metabolism but with regional differences, requiring special attention to clinical interpretation. On a pathophysiological perspective, these findings could help understand underlying neurological effects of KD through possible decrease of oxidative stress in posterior regions and functional compensation in the limbic regions.

And the most f***** up thing about it is that many people would actually believe it.

Of course that is not the how things work but people will believe everything that they see on the internet.

I didn't miss your point about left and right being an arbitrary distinction, I disagree with it. :-)

For beliefs before COVID, of course that's before COVID misinformation started. Once it started, it's pretty clear which political side was having more misinformation pushed on Facebook.

So I guess I think the methodology is clear enough. Nothing in politics or human psychology can be configured to the last decimal, but it's pretty clear at this point what the policies and opinions of the American right tend to be. And how they tend to be different from the American left.

I thank you missed my point that left and right and subjective and arbitrary. That said; per the NIH, before Covid around 22% on both groups believed “Vaccinations can have serious side effects that cause more harm than some of the diseases that they are supposed to prevent.”

I’m also not presenting some sort of politically charged analysis, only saying that they need to present more detail about their methodology since they are using highly subjective topics that I have have experience with.

And with the advent of apps like Tik Tok the attention is man of people is going to sink even more now.

People really find hard to read any kind of newspapers for anything these days.
