Ernährungsmedizinische Bedeutung von Ketonkörpern

Zusammenfassung

Hohe Ketonkörperspiegel im Blut und eine Ketonämie finden sich im Hunger, bei Malnutrition und fortgeschrittene Kachexie (bei fortgeschrittenen Tumorerkrankungen) sowie schweren Stoffwechselentgleisung (bei Diabetischer Ketoazidose). Ketonkörper haben heute auch eine Bedeutung in der Diätetik (als low carb- oder ketogene Diäten zur Behandlung von Hyperinsulinämie, Insulinresistenz und Übergewicht), als ergogene Substanzen (z. B. im Sport), in der Therapie (z. B. in Form von fasting mimicking diets, FMD, in der Onkologie) und in der Diagnostik des Energiestoffwechsels.

Abstract

Elevated ketone body levels are found in starvation, malnutrition and advanced cachexia (in advanced cancer diseases) as well as severe metabolic derailments (in diabetic ketoacidosis). Today, ketone bodies are also important in dietetics (as low carb or ketogenic diets for the treatment of hyperinsulinaemia, insulin resistance and obesity), as ergogenic substances (e. g. in sport), in therapy (e. g. in the form of fasting mimicking diets, FMD, in oncology) and in the diagnosis of energy metabolism.
