Ketone bodies: from enemy to friend and guardian angel
During starvation, fasting, or a diet containing little digestible carbohydrates, the circulating insulin levels are decreased. This promotes lipolysis, and the breakdown of fat becomes the major source of energy.

Differential utilization of ketone bodies by neurons and glioma cell lines: a rationale for ketogenic diet as experimental glioma therapy [PDF]
Background: Even in the presence of oxygen, malignant cells often highly depend on glycolysis for energy generation, a phenomenon known as the Warburg effect.

Ketone bodies are low chain organic substances with four carbon atoms, with β-hydroxybutyric acid and acetone being the main ketone bodies in blood circulation. Under physiological conditions their levels are low while during conditions of oxidative stress, such as exercise, fasting state and acute illness, ketone body levels are increased.

Objective: Throughout the last decade, interest has intensified in intermittent fasting, ketogenic diets, and exogenous ketone therapies as prospective health-promoting, therapeutic, and performance-enhancing agents.

Hypothalamic sensing of ketone bodies after prolonged cerebral exposure leads to metabolic control dysregulation. [PDF]
Ketone bodies have been shown to transiently stimulate food intake and modify energy homeostasis regulatory systems following cerebral infusion for a moderate period of time (<6 hours). As ketone bodies are usually enhanced during episodes of fasting,

Ketogenic diet versus ketoacidosis: what determines the influence of ketone bodies on neurons?
Glucose is the main energy substrate for neurons, however, at certain conditions, e.g. in starvation, these cells could also use ketone bodies. This approach is used in clinical conditions as the ketogenic diet.

Ketone bodies as signaling metabolites [PDF]
Traditionally, the ketone body β-hydroxybutyrate (βOHB) has been looked upon as a carrier of energy from liver to peripheral tissues during fasting or exercise. However, βOHB also signals via extracellular receptors and acts as an endogenous inhibitor of histone deacetylases (HDACs). These recent findings support a model in which βOHB functions to link

Determination of 14C radioactivity in ketone bodies: a new, simplified method and its validation.
A rapid and reproducible method for the assay of 14C radioactivity in ketone bodies is described, based on the heat lability of acetoacetate and the ability of beta-hydroxybutyrate to quantitatively bind to and elute from an ion exchange resin. Potential

Ketogenic diets consist of low carbohydrate/high fat, shifting energy reliance from glucose to ketone bodies. Ketone diester supplement to a standard diet (ketone ester) increases ketone bodies by adding a substance without altering other consumed foods.

Ketone Bodies, Potential Therapeutic Uses [PDF]
AbstractKetosis, meaning elevation of D‐ β‐hydroxybutyrate ( R ‐3‐hydroxybutyrate) and acetoacetate, has been central to starving man's survival by providing nonglucose substrate to his evolutionarily hypertrophied brain, sparing muscle from destruction for glucose synthesis.
