Humans evolved colour vision to detect ripe fruit. Fruit has a, relatively, considerable amount of sugar. For such a substantial mutation, for which all of us share, it would seem counter-productive to evolve such a trait that harms us.

#42Earlier quoted context omitted.
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) desp…
We might be referring to different “second” papers :) https://www.sciencedirect.com/science/article/abs/pii/S00319... is about about perceived sweetness https://www.nature.com/articles/s41430-020-00749-6 is about glycemic response, which I referred to as the second paper Though it could be argued that both papers were trying to figure out why glucose = bad (the first, testing perceived sweetness, and the second, glyc…

#44It'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‘ve heard claims that it also slows neurological aging, no idea how valid that is.

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?
Too much protein can take you out of ketosis, but people think they can just eat lean hamburger three times a day.
If the fat/protein ratio is right, the inability to focus can be a symptom of electrolyte deficiency, particularly sodium, potassium, and magnesium. You should be getting potassium and magnesium from vegetables, but supplements can be a useful diagnostic tool: If you take 400 mg of potassium and find, an hour later, that you're thinking more clearly, that's data.
Don't overdo it with electrolyte supplements, though; too much sodium can increase the calcium in your blood enough to give you kidney stones, if you're lucky, and worse effects if you're unlucky. Too much potassium can mess with your heart.

Calorie restriction is a sure way to get brain fogs, and it's easy to inadvertently be in caloric deficit when on keto, because you have to give up many foods, and there are no sudden cravings for sugary/starchy food.

Earlier fruits didn't have anywhere near the sugar content of the cultivated ones today. In fact, many fruits of old were inedible (e.g. apples). Sources of sugar such as sweet fruits and honey were rare delicacies, not daily occurrences. Humans in various regions would have adapted over 1000 generations to better match their environment. We live in a VERY different world now.

#49There's a big difference between eating/drinking pure sugar and eating a well-balanced meal with carbs. Yeah, the former will make you feel terrible and perform worse. But would the latter really affect you vs. a meal without carbs?

Fruit is meant to be eaten, so as long as plants have the spare energy, I don't see why they wouldn't make lots of appealing fruit.
Veggies would make more sense to be bitter.
Also, where did you get 1000 generations from? That's 20000 years in one place. It seems like a lot of humans would be a lot more mobile than that.
