Ketosis vs. Ketogenesis

Ketosisnoun

(pathology) A metabolic state in which the body produces ketones to be used as fuel by some organs so that glycogen can be reserved for organs that depend on it. This condition occurs during times of fasting, starvation, or while on a ketogenic weight-loss diet.

Ketosisnoun

an abnormal increase of ketone bodies in the blood as in diabetes mellitus

Ketosis

Ketosis is a metabolic state characterized by elevated levels of ketone bodies in the blood or urine. Physiologic ketosis is a normal response to low glucose availability, such as low-carbohydrate diets or fasting, that provides an additional energy source for the brain in the form of ketones.

Ketogenesisnoun

The metabolic breakdown of fatty acids to produce ketone bodies.

Ketogenesis

Ketogenesis is the biochemical process through which organisms produce ketone bodies by breaking down fatty acids and ketogenic amino acids. The process supplies energy to certain organs, particularly the brain, heart and skeletal muscle, under specific scenarios including fasting, caloric restriction, sleep, or others.
