Ketosis

Ketosis (/kɪˈtoʊsɪs/ ki-TOH-sis) is a metabolic state characterized by elevated levels of ketone bodies in the body tissues, which is typically pathological in conditions such as diabetes, and normal in some dieting situations.

Etymology

The term "ketosis" originates from the Greek word "κῆτος" (kētos), meaning "sharp, piercing" and the suffix "-osis", indicating a process or condition. The term was first used in the medical literature in the early 20th century.
