and by using ketones and fatty acids to create a bit more glucose for
the brain via gluconeogenesis in a fairly «energy inefficient» process.
Not exact matches
After three weeks, the acclimation (we call it «keto - adaptation») is usually complete and
brain cells start to thrive on a mix of ketones and the small amount of glucose produced in the liver
via gluconeogenesis in the complete absence of carbohydrates.
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!)
Contrary to the popular belief that a constant intake of carbs are necessary for healthy
brain and nervous system function, our body,
via the liver, makes both glucose (
gluconeogenesis) and ketone bodies (ketosis) in ample amounts (under the right conditions) to fuel most of the athlete's
brain & nervous system needs under all but racing or long brick training conditions.
One correction though — your
brain does not need carbohydrates, it needs glucose, and you can also get that from protein
via gluconeogenesis.
