Makes sense. The brain needs fuel. Without adequate fuel there's no way for it to grow, unless the body gave up some of its need for the same fuel. So I would presume there's that as well. That is, the body also evolved to feed the brain.


Well fat to grow but it burns sugar


It can burn glucose (table sugar is sucrose).

It can also burn other stuff [0] and have almost no requirements for glucose, all of which can be provided through gluconeogenesis from amino acids and the glycerol backbone of fat.

It prefers to burn glucose. You have to be starving it to get it to use ketones.

What does that tell you?


Your body also prefers to metabolize ethanol (which provides quite a bit of energy, by the way) before anything else in the bloodstream.

What does that tell you?

Absolutely nothing. I could go with the "get rid of poison" narrative, but that is a bit too extreme and is usually taken with a great deal of psychological resistance. I couldn't blame you.

Also, I believe that a well-formulated ketogenic diet is pretty far from starvation, enabling me to do exactly the same, if not more, as when I was running on carbohydrate. Of course, you might believe otherwise, but do take the time to think critically about where this belief stems from.

A keto diet is good for cutting weight while bodybuilding, or doing any sporting endeavor and you got fat, but prolonged periods on it will damage the brain.

"Of course you may believe otherwise" and so on


I must be missing something. What is the relevant portion of the article you linked? They even praise the ketogenic diet.

In case you wonder, the brain uses around 25% glucose and 75% ketones even in deep ketosis. Glucose in the blood is stable, and spent glucose is replenished through gluconeogenesis on demand.

I would like to know what your point is here. Thanks.


It doesn't praise ketogenic diet anywhere. Quote it then. My point is that the ketogenic diet is useless for anyone but eppilieptics or those wanting to lose weight fast, bodybuilders or sports that require weight limits

"Within minutes, glucose depletion and associated compromised bioenergetic pathways cause extensive neuronal death in the core of the infarction, and over time in the surrounding tissue"

Someone on here is going to read your bad advice, and god forbid, follow it. Here's my two cents


The paper you linked mentions the diet twice, and both mentions are positive:

> Early diagnosis of the GLUT1 deficiency syndrome is important because adherence to a ketogenic diet (Glossary) [15] is an effective treatment for most patients [83]; in general, ketogenic diet efficiently suppresses epileptic seizures in childhood drug-resistant epilepsy [87].

Regarding your quote, please read the sentence right before it:

> A thromboembolic occlusion of a brain-supplying artery leads to an acute disruption in blood supply to a specific brain territory, causing cerebral ischemia (Figure 1b). Within minutes, glucose depletion and associated compromised bioenergetic pathways cause extensive neuronal death in the core of the infarction, and over time in the surrounding tissue [90, 91].

The sentence you quoted is in the context of a fucking stroke and has absolutely nothing to do with diet. Are you aware of that?

And again, the brain still has glucose readily available (and uses it) when on a ketogenic diet.

Please do try to inform yourself and/or read more carefully before judging others' views.


I was under the impression one of the things the brain "burns" is cholesterol. Yes? No?
