#2This 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.

#3Interesting, but a later paper that cites this one did not get the same result. https://www.nature.com/articles/s41430-020-00749-6

So diet cola doesn't make you dumber?

#6It'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).

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.

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 out why, the second paper compared glucose and isomaltulose (glucose-containing saccharides with different glycemic responses) to see whether a sugar’s predicted glycemic response could account for the differences in cognitive performance noticed in the earlier study between beverages with glucose and those without.
[1] This second paper’s abstract doesn’t mention glucose vs. no glucose’s effects on cognitive performance like the earlier paper does.

I was keto for six months a year or so ago and definitely felt sharper at the time as well. Turns out I like carbs more than clear headedness

I've read that keto diets cause brain fog. I searched it quickly and a bunch of results turned up, too.
Is keto intended to be a long term diet?
