The Indians asked the Windigo if there was any fat on them. He said, "You bet there is, I have eaten lots of Indians, no wonder they are fat." The Indians then killed him and cut him to pieces. The end of this Giant Windigo. Human cannibalism
In some traditions, humans overpowered by greed could turn into wendigos; the myth thus served as a method of encouraging cooperation and moderation. Other sources say wendigos were created when a human resorted to cannibalism to survive. Humans could also turn into wendigos by being in contact with them for too long. Taboo reinforcement ceremony
Among the Assiniboine, the Cree, and the Ojibwe, a satirical ceremonial dance is sometimes performed during times of famine to reinforce the seriousness of the wendigo taboo. The ceremony, known as wiindigookaanzhimowin, was performed during times of famine, and involved wearing masks and dancing backward around a drum. The last known wendigo ceremony conducted in the United States was at Lake Windigo of Star Island of Cass Lake, within the Leech Lake Indian Reservation in northern Minnesota. Psychosis
In historical accounts of retroactively diagnosed Wendigo psychosis, it has been reported that humans became possessed by the wendigo spirit, after being in a situation of needing food and having no other choice besides cannibalism.
In some First Nations communities other symptoms such as insatiable greed and destruction of the environment are also thought to be symptoms of Wendigo psychosis. Etymology
The word appears in many Native American languages, and has many alternative translations. The source of the English word is the Ojibwe word wiindigoo. In the Cree language it is wīhtikow, also transliterated wetiko. Other transliterations include Wiindigoo, Weendigo, Windego, Wiindgoo, Windgo, Windago, Windiga, Wendego, Windagoo, Widjigo, Wiijigoo, Wijigo, Weejigo, Wìdjigò, Wintigo, Wentigo, Wehndigo, Wentiko, Windgoe, Wītikō, and Wintsigo. A plural form windigoag is also spelled windegoag, wiindigooag, or windikouk.The Proto-Algonquian term has been reconstructed as *wi·nteko·wa, which may have meant "owl". Parallels
The Wechuge is a similar being that appears in the legends of the Athabaskan people of the Northwest Pacific Coast. It too is cannibalistic; however, it is characterized as enlightened with ancestral insights. Folklore
Description
The wendigo is part of the traditional belief system of a number of Algonquin-speaking peoples, including the Ojibwe, the Saulteaux, the Cree, the Naskapi, and the Innu. Although descriptions can vary somewhat, common to all these cultures is the view that the wendigo is a malevolent, cannibalistic, supernatural being. They were strongly associated with winter, the north, coldness, famine, and starvation.Basil H. Johnston, an Ojibwe teacher and scholar from Ontario, gives a description of a wendigo:

The Wendigo was gaunt to the point of emaciation, its desiccated skin pulled tightly over its bones.
