Your body naturally goes into ketosis when you go for several days with low or restricted carbohydrate in your diet. The main ketones produced within the body are beta-hydroxybutyrate, acetoacetate and acetone. Ketones are produced by the liver from fat and provide an energy source that acts as a substitute for glucose for the cells of the body to produce ATP.
This page serves as the main page for all things "KETONE". Explore relevant topics regarding the basics of ketone metabolism, the history and uses of the ketogenic diet, and more via the links below.
Under normal conditions the body breaks down carbohydrates, lipids, and proteins to provide energy. In general, following a meal the body metabolizes both carbohydrates and lipids before breaking down proteins. The brain is a special organ as it is virtually completely dependent on carbohydrates for energy. The body's store of carbohydrates is depleted within a few days of carbohydrate restriction or fasting, putting brain function at risk. The ability to produce and breakdown ketones evolved as a adaptation that converts fat into an energy form to be used by the brain when carbohydrate levels are low.
The macronutrient composition of a ketogenic diet is high in fat, adequate in protein and low in carbohydrate (usually >50g per day). The diet aims to trigger ketone production without the need for fasting. Potential uses of the ketogenic diet include weight-loss, management of neurological and metabolic illness and to improve endurance performance in sport. (Learn more)
There are no naturally occurring sources of dietary ketone bodies; however, synthetic ketones (or ketone precursors) are a potential alternative to dietary manipulation to achieve ketosis. Exogenous ketone supplementation creates a novel physiological state, where ketone bodies reach a level usually seen after prolonged fasting, but with no shortage of other dietary macronutrients. Exogenous ketone drinks can alter your metabolism and provide an extra fuel for the body that improves physical and cognitive performance.
Ketone esters are the only ketone supplements that are supported by published peer-reviewed studies showing that they are safe for human consumption, and can improve physical and cognitive performance in humans and rats. Evidence strongly suggests that taking ketone easter drinks along with gold standard carbohydrate can unlock greater physical and cognitive performance. (Learn more)
Whenever it comes to new athletic performance-enhancing supplements, the substances are carefully scrutized. Sports drinks containing ketone formulations are one of the latest trends amongst elite endurance athletes. Although the World Anti-Doping Agency (WADA) has stated that ketones are currently not on the list of banned substances, there remains some controversy around them. Ketones shouldn't be banned because they are safe for use and can provide exciting performance gains. Consumers should be careful not to confuse ketone formulations meant for athletic supplementation with "raspberry ketone" weight loss products sold online. (Learn more)
