metabolic
AmericanUsage
What does metabolic mean? Metabolic describes something that is related to or is affected by metabolism, as in Dr. Petrov discovered the patient’s illness had metabolic causes. Your metabolism is the sum of the physical and chemical processes in your body needed to sustain life by producing energy. In humans, metabolism involves a large number of different organs and tissues. For this reason, the word metabolic is frequently used in medicine, nutrition, and other health sciences to discuss the digestive system, circulatory system, and other bodily processes. Example: While studying the birds, the researchers conducted intense studies of the animals’ metabolic rate increases during prolonged flights.

Etymology
Origin of metabolic
First recorded in 1735–45; from Greek metabolikós “changeable,” from metabol(ḗ) “change” + -ikos -ic; see metabolism
Explanation
The adjective metabolic describes anything relating to the processes in the body that change food into energy. The high metabolic rate of an endurance athlete requires them to eat enormous meals. Metabolic processes are incredibly complicated, and they happen at the cellular level in human (and non-human) bodies. Turning calories from food into energy which keeps a body moving is just the simplest way to think about metabolic activity. When you consider the change that occurs (a peanut butter and jelly sandwich transforming into energy you use to play a soccer game), the root of metabolic makes total sense: it's the Greek metabole, "a change."
