What are ketones?

Updated 4 months ago by Taylor

Ketones are produced when the body doesn't have enough glucose to meet its fuel needs. The liver breaks down fat to produce ketones and releases them into your bloodstream. Ketones can be used as fuel by the brain and virtually all tissues in the body.

In human biology, there are three molecules referred to as ketones: beta-hydroxybutyrate (BHB), acetoacetate (AcAc), and acetone. These biological ketones are a fuel source that our bodies can naturally produce from breaking down fat.

BHB and AcAc are the most important ketones for providing fuel to the muscles and brain. Acetone is a by-product of AcAc breakdown and is mainly released in the breath, and not used for fuel.

Our bodies produce ketones when we fast or follow a strict low-carbohydrate diet. That said, the time it takes for your ketone levels to rise depends on your metabolism and the methods you're using.

Drinkable ketones (ie: Ketone-IQ™️) can be burned by the body using the same pathways as ketones produced through diet or fasting.
