source for these malfunctioning cells and reduce symptoms
of Alzheimer's (28).
When carbohydrates,
body's primary
source of energy, are limited and not used efficiently, these
ketones supply all the energy that your brain needs to perform its functions efficiently.
The overall calorie intake is low (1000 - 1200 kcal), most likely lower than maintenance level, so that's why the
body will have to use another
source of energy (
body fat and
ketones).
Your
body gets into a state
of ketosis, when
ketones, instead
of carbohydrates become your
body's
source of energy.
They have an extreme
source of efficient energy from the
ketones, and when they are used up, any excess fat on their
bodies.
Ketones are used as a
source of fuel for the
body instead
of the energy produced from sugar / carbs.
Ketones are produced when the
body begins breaking down fats into fatty acids and are the
body's signal to start using both dietary and
body fat as the primary
source of energy.
The ketogenic diet promotes higher intake in fats, medium intake
of protein and reduced intake in carbohydrates, and leaving the
body with not much choice, but to start producing
ketones using the fat and making it the main
source of energy.
Using a high - quality coffee
source, such as Bulletproof coffee (that doesn't contain mycotoxins), with grass - fed butter and MCT oil can be a great way to give your
body an extra supply
of healthy fats, which will allow your
body to produce more
ketones for fuel (these fats are also anti-inflammatory).
By having
ketone bodies as an additional
source of fuel, the dependence on glucose is reduced.
The Ketogenic Diet is one which promotes ketosis: a state where the
body uses fat as the main energy
source instead
of carbs, essentially by converting fat (dietary or stored) into
ketone bodies.
Although glucose is known to be the primary
source of energy (your
body naturally prefers glucose), it's nowhere near as efficient as
ketone bodies, especially for the brain.
