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…

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.

Probably a memory of the taste and the vitamins that follow it. My wife craves mints when she's low on iron.

But do mints provide any iron?

Depends on which kinds. Spearmint can contain up to 15% of your DV of iron.

I know this is the conventional wisdom but it doesn't really make sense. Controlling a sperm whale's body doesn't seem like a hard computational problem.

I assume you mean relative to controlling a human body?

Relative to anything smaller really.

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.

There is no one "Indian" culture. In the eastern Indian state of West Bengal, goat bone marrow is relished a lot, and fatty fish brain is relished and considered brain food.

Does this mean Ghee is generally not used in WB? Sure there will be local variations due to a variety of factors - invasion of other cultures (islamic, christian, chinese etc) The Ghee thing does have its general influence in Indian culture.

Ghee is used in WB but bone marrow is loved a lot by young and old alike and I thought it pertained to the report.

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.

Yp, brain uses tremendous amount of energy so there's a cost. Use too much of it to build the brain and you starve...use too little and same result since you're outsmarted. Rinse repeat until it's perfected.

Heyenas have 2 extra legs to waste energy on. Not much left in the budget for a big brain.

Rats have a similar brain-to-body mass as humans. Cats are fairly intelligent, are they not?

I use to feed street dogs in Thailand. I gave them BBQ-cooked chicken legs, and gosh, there would be nothing left in 10 seconds.

While I'm sure you did this out of good will, please don't give chicken bones to dogs. They tend to splinter, leaving sharp spikes that may hurt the dog's intestines. Beef and pork bones are better since these don't shatter.

I have a chicken in the slow cooker almost every single day. If the bones have cooked for more than 12 hours, it’s not possible for them to harm anyone. They’re too soft. By the time is they have simmered 24 hours, they are easily chewable.
