Gluconeogenesis (GNG) is a metabolic pathway that results in the generation of glucose from certain non-carbohydrate carbon substrates. It is a ubiquitous process, present in plants, animals, fungi, bacteria, and other microorganisms. [6] In vertebrates, gluconeogenesis occurs mainly in the liver and, to a lesser extent, in the cortex of the ...

Ultimately almost all biomolecules come from the assimilation of carbon dioxide in plants and microbes during photosynthesis. [68]: 359 The free energy of formation of α-d-glucose is 917.2 kilojoules per mole. [68]: 59 In humans, gluconeogenesis occurs in the liver and kidney, [89] but also in other cell types.
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.
The Maternal and Child Nutrition Study Group estimate that under nutrition, "including fetal growth restriction, stunting, wasting, deficiencies of vitamin A and zinc along with suboptimum breastfeeding—is a cause of 3.1 million child deaths and infant mortality, or 45% of all child deaths in 2011".

Plant nutrition is the study of the chemical elements and compounds necessary for plant growth and reproduction, plant metabolism and their external supply. In its absence the plant is unable to complete a normal life cycle, or that the element is part of some essential plant constituent or metabolite .
Compensatory growth, known as catch-up growth and compensatory gain, is an accelerated growth of an organism following a period of slowed development, particularly as a result of nutrient deprivation. [1] [2] The growth may be with respect to weight or length (or height in humans).
With diagnosis before serious harm occurs, prompt reversal of acidotic episodes, and appropriate long-term treatment, most children will be healthy. With exceptions and qualifications, adult health and life span may also be fairly good, although the lack of effective treatment before the mid-1980s means information on long-term efficacy is limited.
