Just about everyone is familiar with how the body uses glucose as a fuel source. In short, food is turned to glucose, and then insulin works to get the glucose into the cells for energy (known as ATP). Excess glucose can be stored as fat or stored in the liver and muscles as glycogen.
Carbohydrates, for example, quickly convert to glucose for quick energy. While glucose is the most common form of energy, there is a more efficient source of energy known as ketones.
Ketones, such as acetoacetate and beta-hydroxybutyrate (BHB), are a by product of fat oxidization. This is what your body produces and uses as fuel when glucose is very low and your body starts to burn the fat (known as ketosis). Ketones have a caloric value (roughly 4.5 to 5.5 calories per gram), so they are an actual energy source, not stimulants. That’s a higher energy yield than carbs or protein.
So, why are ketones better and more efficient than glucose? Ketones can be used by the cells as energy without the need for insulin to get the ketones into the cells. While excess glucose is stored as fat, excess ketones are not stored. etones also preserve and protect muscle, which is a major benefit when trying to reduce carbs and sugar in your diet. You don’t want your body turning to protein (the muscle) for energy, thereby losing muscle mass.
Endogenous ketones are ketones created in the body when you convert stored fat into energy. Exogenous ketones are ketones put into the body from a supplement such as Pruvit’s KETO-OS. This product contains a little more than 8 grams of beta-hydroxybutyrate salts and MCT oil (medium-chain triglycerides) that the body can use for energy right away without the need for insulin. KETO-OS stands for “Ketone Operating System.” You can prove KETO-OS puts ketones in your body with a blood or urine test.
So, for the first time every, you can have glucose as a fuel source but now introduce ketones as a second and more efficient fuel source that used to only be available by reaching ketosis through strict dietary restrictions.
