Ketones.
As the fast continues and glycogen is depleted, the body finds a way to use its fat to fuel the brain. It adapts by combining acetyl CoA fragments derived from fatty acids to produce an alternative energy source, ketone bodies.
Glucose is the primary fuel source for the brain. It is converted into energy through a process called cellular respiration to power the brain's functions. The brain can also use ketone bodies as an alternative fuel source during times of fasting or on a low-carbohydrate diet.
While the brain can use both glucose and ketones for fuel, it has a preference for glucose. However, during periods of fasting or on a ketogenic diet, the brain can efficiently use ketones, which are produced from fat breakdown, as an alternative fuel source.
The preferred source of fuel for the brain is glucose, which is a type of sugar that comes from carbohydrates in the diet. The brain relies on a steady supply of glucose to function properly and efficiently.
The brain's preferred fuel source for optimal functioning is glucose, which is a type of sugar that comes from carbohydrates in our diet.
Ketone bodies are produced in the body when there is a shortage of glucose for energy. This typically happens during periods of fasting, low carbohydrate intake, or intense exercise. The liver converts fatty acids into ketone bodies, which can then be used as an alternative fuel source by the brain and muscles.

Well, without a doubt some of the fuel needed by the brain after the body has been fasting is drawn from the body's fat reserves. Some probably comes from muscle tissues as well, although this is probably a lesser amount. Portions more than likely vary depending on the physical fitness of the individual. When fat reserves are depleted, and the body is still in a state of fast, major organs will begin to be consumed to keep the brain intact. I can't tell you specifically where to verify any of this, or even that it is necessarily true. It is true to the best of my knowledge, but I am by no means an expert.
Glucose is the preferred source of energy for the brain and central nervous system. It is converted into ATP through cellular respiration to fuel the energy demands of these vital organs. Although the brain can use ketone bodies in times of fasting or low carbohydrate intake, glucose remains the primary and most efficient fuel source for optimal brain function.

pia materpia materThe membrane that supplies most of the blood to the brain is the pia mater.
In the Alzheimer's brain, insulin does not function well and does not help brain cells gather glucose from the blood which fuels their function. Ketones work as an alternate brain fuel. Ketones can be synthesized in your liver from coconut oil.
Well ... the blood supplies both the sugar and the oxygen that the brain requires.
Supplies power to the fuel pump.
A FUEL SYSTEM stores, and supplies fuel to the cylinder chamber where it can be mixed with air (air & fuel ratio) to transmit power
No, of course not. The fuel pump supplies fuel to the engine. The engine will not run without a supply of fuel.
