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.
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.
Another estimate also by WHO states that childhood underweight is the cause for about 35% of all deaths of children under the age of five years worldwide. [6] According to a 2008 review, an estimated 178 million children under age 5 are stunted, most of whom live in sub-Saharan Africa. [15]
The agency, which falls under the the Department of Health and Human Services, has a massive purview, regulating about 77% of the U.S. food supply and overseeing the safety of nearly $4 trillion ...
These types of fad diets often include extreme calorie deficits that can cause the body to enter “starvation mode,” she says, which often results in muscle loss, water retention, and a slower ...
Fasting is an ancient tradition, having been practiced by many cultures and religions over centuries. [9] [13] [14]Therapeutic intermittent fasts for the treatment of obesity have been investigated since at least 1915, with a renewed interest in the medical community in the 1960s after Bloom and his colleagues published an "enthusiastic report".

Identification of the social conditions that causes malnutrition in children under five has received significant research attention as it is a major public health problem. [ citation needed ] Undernutrition most commonly results from a lack of access to high-quality, nutritious food. [ 5 ]
Prolonged fasting (also called extended fasting or water fasting) involves periods of fasting above 24 hours, typically in the range of 5–20 days. [13] In early fasting, the body operates under a relatively high level of gluconeogenesis, though this eventually decreases as the body's metabolism switches into ketosis, causing ketones to ...
