Thrifty Phenotype

Thrifty phenotype (/ˈθrɪftiː/ /ˈfiːnətaɪp/) is a biological concept that refers to the proposed ability of an organism to effectively manage its energy resources in response to environmental changes. The term was first coined by British epidemiologist David Barker in the early 1990s.

Etymology

The term "thrifty" is derived from the English word "thrift", which means careful management of resources, particularly money. The term "phenotype" comes from the Greek words "phainein" (to show) and "typos" (type). Thus, "thrifty phenotype" essentially means a type that shows thriftiness or careful management of resources.

Concept

The thrifty phenotype hypothesis suggests that conditions in the womb can shape the metabolism and physiology of the offspring, predisposing them to metabolic conditions such as diabetes and obesity later in life. This is thought to occur as a result of the fetus adapting to a nutrient-poor environment in the womb, leading to a "thrifty" metabolism that is beneficial in conditions of scarcity but detrimental in conditions of abundance.
