most extreme form of malnutrition, a consequence of prolonged insufficiency of food

Starvation happens when a living being (like a person or an animal) doesn't eat enough food to live properly. If a living thing is starving for a long period of time, it dies.

Starvation can be seen as an extreme version of hunger. During starvation, the body will slowly but surely become less fat and stop working properly, until the living being dies or eats enough again to stop starving.

There are other effects of starvation. These can include:

When the body is starving, the body will start eating itself in a final attempt to survive. When there are no muscles and fat left to eat, the person (or animal) dies. People who eat nothing usually die in a few months.

Even when a starving person eats again, they may have permanent damage to their body.

Some people intentionally starve themselves to lose weight, but this is considered a bad idea because it may damage the human body.

In history, countries used to use starvation as a form of the death penalty.

In 1944 Ancel Keys started a scientific experiment about starvation to see the impact of starvation on people and to see how people could best recover from starvation. The participants were all men. They ate 1800 calories a day.[1]
