List of diets

Some people's dietary choices are influenced by their religious, spiritual or philosophical beliefs.

• Buddhist diet: While Buddhism does not have specific dietary rules, some Buddhists practice vegetarianism based on Mahayana Buddhism's strict interpretation of the first of the Five Precepts.Weintraub, Eileen. {{usurped|1=[https://web.archive.org/web/20200203061437/http://www.serv-online.org/Eileen-Weintraub.htm "Life as a Vegetarian Tibetan Buddhist Practitioner: A personal view"]}}. Society of Ethical and Religious Vegetarians. Retrieved 13 February 2012.
• Hindu diet: It is popular for followers of Hinduism to follow lacto vegetarian diets (though most do not), based on the principle of ahimsa (non-harming). Consuming beef/cattle is forbidden or at least taboo among followers due to cow veneration. Most Hindus in India do intentionally limit their meat consumption one way or another.{{Cite web |last=Corichi |first=Manolo |title=Eight-in-ten Indians limit meat in their diets, and four-in-ten consider themselves vegetarian |url=https://www.pewresearch.org/fact-tank/2021/07/08/eight-in-ten-indians-limit-meat-in-their-diets-and-four-in-ten-consider-themselves-vegetarian/ |access-date=2022-08-01 |website=Pew Research Center |language=en-US}}
• Jain diet: Due to how the Jain faith interprets ahisma, vegetarianism is considered mandatory for followers; a lacto-vegetarian diet{{Cite book |last=van Popering |first=Ruben |url=http://urn.kb.se/resolve?urn=urn:nbn:se:liu:diva-119663 |title=Jain Vegetarian Laws in the City of Palitana : Indefensible Legal Enforcement or Praiseworthy Progressive Moralism? |date=2015}} or vegan diet{{Cite journal |last1=Miller |first1=Christopher Jain |last2=Dickstein |first2=Jonathan |date=July 2021 |title=Jain Veganism: Ancient Wisdom, New Opportunities |journal=Religions |language=en |volume=12 |issue=7 |pages=512 |doi=10.3390/rel12070512 |issn=2077-1444|doi-access=free }} in particular is considered appropriate for Jains. Most Jains also abstain from consuming root vegetables in order to prevent harming insects, worms and microorganisms when they are uprooted. Most also partake in some form of fasting. Some variants of Jainism further discourage or forbid the consumption of honey, fungi, alcoholic beverages and fermented foods.
• Islamic diet: Muslims follow a diet consisting solely of food that is halal – permissible in Islam. The opposite of halal is haraam, food that is Islamically impermissible. Haraam substances include carnivores, pork and other non-ruminant animals, and any meat from an animal which was not killed through the Islamic method of ritual slaughter (Dhabihah).[http://www.halalcertified.com/halal.html "What do Halal, Dhabiha Halal and Haram Mean?"] {{Webarchive|url=https://web.archive.org/web/20120827000216/http://www.halalcertified.com/halal.html |date=27 August 2012 }}. halalcertified.com. Retrieved 11 March 2012. If an otherwise Halal animal was subject to torture by humans, its meat can still be considered non-permissible for Muslims.
• I-tal: A set of principles which influences the diet of many members of the Rastafari movement. One principle is that natural foods should be consumed. Emphasis is put on consuming produce that is fresh, organic and ideally grown at home or locally. Another principle involves avoiding "unclean" types of food; the definition which is influenced by Biblical teachings. In order to preserve "life energy" Rastafarians encourage teetotalism, and many Rastafarians interpret I-tal to advocate vegetarianism or veganism as well.[http://www.dundee.ac.uk/chaplaincy/guidetoreligions/rastafarianism/ "Rastafarianism"] {{Webarchive|url=https://web.archive.org/web/20160605162631/http://www.dundee.ac.uk/chaplaincy/guidetoreligions/rastafarianism/ |date=5 June 2016 }}. University of Dundee. Retrieved 11 March 2012. Many followers do view seafood as an acceptable addition to an I-tal diet but they restrict which kinds they permit; fish over a foot long are typically avoided and all shellfish are eschewed as they are not kosher animals—unlike finned-fish with scales.
• Kosher diet: Food permissible under kashrut, the set of Jewish dietary laws, is said to be kosher. Some foods and food combinations are non-kosher, and failure to prepare food in accordance with kashrut can make otherwise permissible foods non-Kosher.{{Cite news |url=https://www.thespruce.com/introduction-to-kosher-food-2122519 |title=Kosher Food 101: the Basics of Which Foods Are Kosher |work=The Spruce |access-date=12 October 2017 |archive-date=12 October 2017 |archive-url=https://web.archive.org/web/20171012204528/https://www.thespruce.com/introduction-to-kosher-food-2122519 |url-status=live }}
• Seventh-day Adventist diet: Combines the kosher food rules of Judaism with prohibitions against alcoholic beverages and (sometimes) caffeinated beverages. There is emphasis on consuming whole foods. Meat-consumption is heavily discouraged but not necessarily disallowed; about half of Adventists are lacto-ovo-vegetarians.{{Cite web |url=http://www.llu.edu/info/legacy/appendixc/ |title=LLUMC Legacy: Daring to Care |website=Adventist Health Study |publisher=Loma Linda University |access-date=3 February 2016 |archive-date=25 April 2016 |archive-url=https://web.archive.org/web/20160425235726/http://www.llu.edu/info/legacy/appendixc/ |url-status=live }} Vegan and pescetarian diets are also more popular among Adventists compared to the general public{{Cite web |title=Adventist Health Study-2 {{!}} Adventist Health Study |url=https://adventisthealthstudy.org/studies/AHS-2 |access-date=2022-08-01 |website=adventisthealthstudy.org |archive-date=7 January 2021 |archive-url=https://web.archive.org/web/20210107145925/https://adventisthealthstudy.org/studies/AHS-2 |url-status=live }} but other Adventists are still willing to eat Kosher meats.
• Word of Wisdom diet: The name of a section of the Doctrine and Covenants, a book of scripture accepted by members of the Church of Jesus Christ of Latter-day Saints. Dietary advice includes (1) wholesome plants "in the season thereof", (2) eating meat sparingly and only "in times of winter, or of cold, or famine", and (3) grain as the "staff of life".{{sourcetext|source=The Doctrine and Covenants|book=Doctrine and Covenants 89|verse=10–17}} Unlike injunctions against tobacco, alcohol, coffee and tea—compliance with meat-avoidance has always remained optional among the Church of Jesus Christ of Latter-day Saints and emphasis on refraining from meat has largely been dropped.Thomas G.

An official church publication states, "modern methods of refrigeration now make it possible to preserve meat in any season".[https://www.churchofjesuschrist.org/manual/doctrine-and-covenants-student-manual/section-81-89/section-89-the-word-of-wisdom "Section 89 The Word of Wisdom"], Doctrine and Covenants Student Manual (Salt Lake City, Utah: LDS Church, 2002), pp. 206–11.

{{main|Dieting}}

A desire to lose weight is a common motivation to change dietary habits, as is a desire to maintain an existing weight. Many weight loss diets are considered by some to entail varying degrees of health risk, and some are not widely considered to be effective. This is especially true of "crash" or "fad" diets.{{Cite web |url=https://www.everydayhealth.com/diet-nutrition/the-facts-on-fad-diets.aspx |title=The Facts on Fad Diets |website=EverydayHealth.com |access-date=6 February 2020}}
