Now, when your
brain's production of insulin decreases, your
brain literally begins to starve, as it's deprived of the
glucose - converted energy it
needs to function normally.This is what happens to Alzheimer's patients — portions of their

brain of an infant
needs slightly more carbohydrate fraction than the
brain of an adult because the
brain of an infant
needs just slightly more
glucose even though infants do run really well in ketones they do have slightly elevated
glucose needs compare to an adult which is why we bring that composition of breast milk down just slightly from the carb standpoint and then for growing adult we would slightly up the fat and slightly up the protein.
This «new
glucose» is what the
brain and other organs use for fuel when they
need glucose.

brain will still
need glucose, which the body now easily makes from excess protein, amino acids or fats.
The biology is similar, but infants have big

needs some
glucose or sugar to function like parts of your

Glucose needs are more proportional to

needs are more proportional to body size;
brain size scales roughly as body size to the 3/4 power (http://www.beyondveg.com/billings-t/comp-anat/comp-anat-4a.shtml).
Your central nervous system, or CNS, and the
brain, the control center of your CNS,
need a continuous supply of
glucose in order to function properly.
Unfortunately, in the carbohydrate dependency paradigm, your body routinely converts lean muscle tissue into
glucose via gluconeogenesis to meet your energy
needs, especially for the
brain (only two percent of body weight, but consuming 20 - 25 percent of total calories!)
Brain still
needs some
glucose (last 25 % of fuel requirements) as do the red blood cells.
This is, of course, to be expected, since the body will begin the process of gluconeogenesis (making of new
glucose) in order to supply the
brain and certain other parts that
need glucose (renal medulla and red blood cells).
Ketone bodies serve to provide dearly
needed «fuel» and energy to the
brain when
glucose levels are low, as in the case of Alzheimer's patients.
The
brain is not a big consumer of
glucose, it only
