Starvation is a severe deficiency in caloric energy intake, below the level needed to maintain an organism's life. It is the most extreme form of malnutrition. In humans, prolonged starvation can cause permanent organ damage [1] and eventually, death. The term inanition [2] refers to the symptoms and effects of starvation.
Stunted growth, also known as stunting or linear growth failure, is defined as impaired growth and development manifested by low height-for-age. [1] It is a manifestation of malnutrition (undernutrition) and can be caused by endogenous factors (such as chronic food insecurity) or exogenous factors (such as parasitic infection).
Starvation response in animals (including humans) is a set of adaptive biochemical and physiological changes, triggered by lack of food or extreme weight loss, in which the body seeks to conserve energy by reducing metabolic rate and/or non-resting energy expenditure to prolong survival and preserve body fat and lean mass.
Prolonged fasting (also called extended fasting or water fasting) involves periods of fasting above 24 hours, typically in the range of 5–20 days.
