- The brain uses ketone bodies as an efficient source of energy when glucose levels are low.
So the ketogenic diet forces your liver to start producing ketone bodies.
- So the ketogenic diet forces your liver to start producing ketone bodies.
- Your entire body is more than capable of burning ketone bodies.
- And then some of those circulating fats get turned into these things called ketone bodies.
- The body will produce ketone bodies which are acetoacetate and beta hydroxybutyrate.
- They need a constant supply of glucose or or ketone bodies, which you can use as when you don't have sugar available to you, right?
- And so ketogenesis refers to making this ketone bodies that are byproducts of fat breakdown, essentially breakdown and then reprocessing.
Examples
-
Ketone bodies are produced as a by-product of using ketogenic amino acids to power the TCA cycle.

Morphology
The term is partially compositional: 'ketone' (a molecule produced when fat is broken down) plus 'body' (here meaning a unit or group) gives the idea of a ketone compound or group of related ketone molecules produced in metabolism. However, this is a technical biochemical term whose precise referents and contexts (specific compounds, liver production, metabolic conditions) require specialist knowledge beyond B1, so learners would grasp a rough sense but not the full meaning.
Etymology
Ketone body gets its name from chemistry and the human body: it means the small ketone chemicals the body makes when it is 'burning fat' for 'energy'. So the name helps you remember that these are ketone chemicals made by the body when you do not eat many 'carbs'.
