Earlier quoted context omitted.

Some would say keto is a way of eating as opposed to a diet that can been seen as a temporary change of eating habits. I've never heard anybody say that keto causes brain fog. In fact a lot of people describes the opposite result which I would think most search results are about. There's also something called "keto flu" which some people experience for some time when they switch to a keto diet. These terms are pretty…

I did keto for 5 months or so back in 2014. I found the brain fog description very apt. I couldn't think beyond a couple of moves ahead, which began affecting my work. Going back to a normal diet I was fine again.

I believe it's very much a person to person thing, I typically feel much clearer on a keto/low carb diet.

Ah, trendy bro science. If you think glucose is bad for you, you lack a rudimentary understanding of biology. No, ketones do not replace glucose. But it’s ok because you probably lack rudimentary understanding of protein and most other health related things. Keep up the zealotry.

Downvoted for tone, not substance.

Interesting, but a later paper that cites this one did not get the same result. https://www.nature.com/articles/s41430-020-00749-6

I dunno. I’ve only read the abstract [1], but I feel like the second paper was like, “glucose = bad because of glycemic response? Nope!” And the first paper was just like, “glucose = bad” That is, the earlier paper noticed that consuming glucose/sucrose-containing beverages reduced cognitive performance compared to consuming beverages with no glucose, and the later paper was trying to figure out why. And to figure ou…

I think you got it mixed up, because the second paper is not

> "glucose = bad because of glycemic response? Nope!”

but rather:

“glucose = bad because of perceived sweetness? Nope!”

There are sweeteners that do not activate insulin (like stevia).

I am not aware if the converse exists though (not-sweet-tasting molecules that activate insulin).

Their case in the paper is that fructose is not "bad" (like glucose is) despite of being very sweet-tasting.

This is big. Highlights: •Glucose and sucrose ingestion led to negative cognitive performances. •Negative effects due to blood glucose increase were more evident with overnight fasting. •Sugar effects on cognitive abilities are likely to be glucose-mediated. •Sweetness perception does not play a role in moderating cognitive performances.

N=49 Interesting results, but I'd take them with a grain of sugar until they get replicated several times over. Especially since they match my bias that sugar=bad.

wordplay on the idiom "take it with a grain of salt"

I appreciate what you did there.

You're overly generalizing?

Nobody says that ketones "replace" (without any detail) glucose, only that ketones "replace glucose as source of energy".

And that is correct, as the citric acid cycle accepts ketones as input for the production of ATP.

Moreover, the body scarcely use any glucides besides as an energy source, so I don't really see your point...

It's only N=1 anecdata but since going to a VLC/Keto diet I've felt cognitively sharper (in addition to other benefits like losing weight, needing less sleep, etc).

I felt noticeably sharper on keto, which at the time I felt like was primarily a lack of sleepiness and an increased ability to focus for necessary durations. Thats how it felt, would love to see non subjective data on this.
