Food deprivation is the restriction of free access to food, particularly in experimental settings where it is used as a technique to manipulate organisms to work for rewards and to establish levels of motivation.

In the wider context food deprivation can lead to hunger, starvation , nutritional deficiencies and malnutrition with broad impacts on cognitive functioning.

Famine and hungerEdit

Food deprivation leads to malnutrition and ultimately starvation. This is often connected with famine, which involves the absence of food in entire communities. This can have a devastating and widespread effect on human health and mortality. Rationing is sometimes used to distribute food in times of shortage, most notably during times of war.^[1]

Starvation is a significant international problem. Approximately 815 million people are undernourished, and over 16,000 children die per day from hunger-related causes.^[2] Food deprivation is regarded as a deficit need in Maslow's hierarchy of needs and is measured using famine scales.^[3]
