These are interesting, but I wouldn’t consider it science.
Maybe it’s because my personal experience with Keto has been completely different.
The BBC program: there are soooooo many other variables than the twins diets that would impact their ability to learn in one morning about charts and day trading, that I take absolutely nothing from this little experiment.
Tufts study: the problem here is using the “low carb diet” for one week. The study should have actually looked at the people AFTER they were in ketosis for a while, they probably didn’t even get into ketosis in one week. So I agree with the study in part, because while your brain is switching from glucose to ketones, yeah, it’s a bit foggy. But once it switches and your body “heals” your brain starts firing much quicker.
My personal experience with the Keto diet has been great. Besides the weight loss, the best way I was able to describe the change in my brain. Before when asked a question, sometimes I would have to “search” my brain for an answer, kind of like, try to think back and link some things together to remember things. In ketosis, the answer is usually there immediately, no searching was required.
example: where did I put my coffee, before ketosis: trace my steps back, think of what I did thirty minutes ago, oh yeah I was in the bathroom, then went to my desk and set my cup down
in ketosis: onmy desk, I’m not sure if the other mental steps are completely skipped over, or if they are just blasted through at hyper speed. Either way, the result is the same, quicker answers to the question.
My concentration was also boosted, ive heard people talk about the effects of aderol on their concentration level, the way they explain it is how I feel when I’m in ketosis.
Basically when I’m in ketosis the “brain fog” feels like it’s just lifted away.
