Ketone bodies are two molecules, acetoacetate and b-hydroxybutyrate. The term. âketone bodyâ is historical: only acetoacetate is an actual ketone. Ketone bodies are. synthesized in the liver from acetyl-CoA. The brain is an important organ. It is metabolically active and metabolically. privileged. The brain generally uses 60-70% of total body glucose requirements, and. always requires some glucose for normal functioning.
Ketogenic diets force your body to adapt to using fat for fuel when glucose (from carbs) is not present, this is known as ketosis. Ketones are a by-product of ketosis and keto sticks (also known as ketostix or ketosticks) are urine testing strips which detect the presence of ketones in the blood. They are small plastic strips with an absorbent pad on the end, you urinate on the absorbent pad and it changes colour to reflect the amount of ketones present in your urine.
