Yea, I get that. But but....the study shows the brain produces fructose from sugar. Even if no fructose sugar is given, the person's brain creates fructose in the brain it seems.

The brain goes to great lengths to create fructose. Note this study was under hyperglycemic conditions. The test subjects (humans) were given 20% dextrose solution. The finding is that glucose turns into fructose in the brain, nothing to do with ketones if I'm understanding correctly.
Most highly energetically sensitive tissues bathe in fructose and go at great lengths to get and keep it. Fetus, gonads, brain, sperm, pancreas, liver, etc. So, fructose cannot be this devil that we are being told it is.
Its is interesting, so brain converts some of glucose into fructose and use it....they say it is under hyperglycemia ,but who knows?!...maybe it happens all the time, these things are not well understood usually , things about brain..as its isolated.
That's interesting, any reference or keyword to search and read more?
Thanks
This news just in - the brain synthesizes its own fructose.

So, the whole premise of the ketogenic diet may be false - i.e. that the brain lives on ketones during ketosis. It is much more likely that the brain ramps up fructose synthesis in times of ketogenic stress and this is of course done by ramping up cortisol production.
Right, I am just saying that if the brain goes through such great lengths to produce fructose it is probably not going to be fooled to switch to burn ketones. It will simply signal to increase cortisol and then use the resulting glucose to keep synthesizing fructose.
The study also calls BS on the mainstream medical claim that fructose is really only targeting the liver because it is the only organ that can metabolize it. Peat said this many times in his articles. Most highly energetically sensitive tissues bathe in fructose and go at great lengths to get and keep it. Fetus, gonads, brain, sperm, pancreas, liver, etc. So, fructose cannot be this devil that we are being told it is.
Seems to be a big part of the naked mole rats bag of tricks as well
Naked mole-rats 'turn into plants' when oxygen is low
Understanding how the animals do this could lead to treatments for patients suffering crises of oxygen deprivation, as in heart attacks and strokes.
"This is just the latest remarkable discovery about the naked mole-rat -- a cold-blooded mammal that lives decades longer than other rodents, rarely gets cancer, and doesn't feel many types of pain," says Thomas Park, professor of biological sciences at the University of Illinois at Chicago, who led an international team of researchers from UIC, the Max Delbrück Institute in Berlin and the University of Pretoria in South Africa on the study.
In humans, laboratory mice, and all other known mammals, when brain cells are starved of oxygen they run out of energy and begin to die.
But naked mole-rats have a backup: their brain cells start burning fructose, which produces energy anaerobically through a metabolic pathway that is only used by plants -- or so scientists thought.
In the new study, the researchers exposed naked mole-rats to low oxygen conditions in the laboratory and found that they released large amounts of fructose into the bloodstream. The fructose, the scientists found, was transported into brain cells by molecular fructose pumps that in all other mammals are found only on cells of the intestine.
"The naked mole-rat has simply rearranged some basic building-blocks of metabolism to make it super-tolerant to low oxygen conditions," said Park, who has studied the strange species for 18 years.
At oxygen levels low enough to kill a human within minutes, naked mole-rats can survive for at least five hours, Park said. They go into a state of suspended animation, reducing their movement and dramatically slowing their pulse and breathing rate to conserve energy. And they begin using fructose until oxygen is available again.
The naked mole-rat is the only known mammal to use suspended animation to survive oxygen deprivation.
The scientists also showed that naked mole-rats are protected from another deadly aspect of low oxygen -- a buildup of fluid in the lungs called pulmonary edema that afflicts mountain climbers at high altitude.
The scientists think that the naked mole-rats' unusual metabolism is an adaptation for living in their oxygen-poor burrows. Unlike other subterranean mammals, naked mole-rats live in hyper-crowded conditions, packed in with hundreds of colony mates. With so many animals living together in unventilated tunnels, oxygen supplies are quickly depleted.

@haidut - I won't be reading it because it's not about something important (such as inulin), but it could easily be a thread of yours, in facto I was surprised that it wasn't:
