List of diets
An individual's diet is the sum of food and drink that she or he habitually consumes. Dieting is the practice of attempting to achieve or maintain a certain weight through diet. People's dietary choices are often affected by a variety of factors, including ethical and religious beliefs, clinical need, or a desire to control weight.
Not all diets are considered healthy. Some people follow unhealthy diets through habit, rather than through a conscious choice to eat unhealthily. Terms applied to such eating habits include "junk food diet" and "Western diet". Many diets are considered by clinicians to pose significant health risks and minimal long-term benefit. This is particularly true of "crash" or "fad" diets–short-term, weight-loss plans that involve drastic changes to a person's normal eating habits.
Only diets covered on Wikipedia are listed.
Belief-based 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 a strict interpretation of the first of the Five Precepts.
- Hindu and Jain diets: Followers of Hinduism and Jainism may follow lacto vegetarian diets, based on the principle of ahimsa.
- Islamic dietary laws: 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 alcohol, pork, and any meat from an animal which was not killed through the Islamic method of ritual slaughter.
- 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. Some Rastafarians interpret I-tal to advocate vegetarianism or veganism.
- 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.
- Seventh-day Adventist: Seventh-day Adventists combine the Kosher rules of Judaism with prohibitions against alcohol and caffeinated beverages and an emphasis on whole foods. About half of Adventists are lacto-ovo-vegetarians.
- Word of Wisdom: 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 wholesome plants "in the season thereof", eating meat sparingly and only "in times of winter, or of cold, or famine", and grain as the "staff of life".

Liquids are often restricted as well—not forbidden, just less of.

Fad diets
Since the "fad" qualification varies over time, social, cultural and subjective view, this list cannot be exhaustive, and fad diets may continue or stop being fads, such as the mediterranean diet. Some of them have therapeutic indications, such as epilepsy or obesity, and there is no one-size-fits-all diet that would be a panacea for everyone to lose weight or look better.
