Detox, short for detoxification, in general is the removal of toxic substances from the body. In conventional medicine, detoxification can also be achieved artificially by techniques such as dialysis and (in a very limited number of cases) chelation therapy. There is a firm scientific base in evidence-based medicine for this type of detoxification. Many alternative medicine practitioners promote various other types of detoxification such as "diet detoxification" but there's no evidence that detox diets have any health benefits.

Detoxification can also refer to the period of withdrawal during which a person's body to return to homeostasis after long-term use of an addictive substance

*** But I’ll mention only in diet detoxification

Diet detoxification

Certain diets have an underlying assumption that the body accumulates toxins that must be removed, especially after periods of over-eating or the consumption of non-nutritious and processed foods. As with alternative medicine, the 'toxins' removed are undefined and are ascribed to foods, the environment and the body's own wastes.

 Detox Diet

A detox diet is a dietary regimen involving a change in consumption habits in an attempt to detoxify the body, by removal of toxins or other contaminants. Proponents claim it improves health, energy, resistance to disease, mental state, digestion, as well as aiding in weight loss. Many scientists, dietitians, and doctors, however, regard 'detox diets' as less effective than drinking a glass of water, and view 'detox diets' as generally harmless but a waste of money.

"Detox" diets usually suggest that fruits and vegetables compose a majority of one's food intake. Limiting this to unprocessed (and sometimes also non-GM) foods is often advocated. Limiting or eliminating alcohol is also a major factor, and drinking more water is similarly recommended.

A list of methods to modify the diet for the purpose of detoxification includes:

·      Eliminating foods that are hard on metabolism, such as caffeine, alcohol, processed food (incl. any bread), pre-made or canned food, salt, sugar, wheat, red meat, pork, fried and deep fried food, yellow cheese, cream, butter and margarine, shortening, etc., while focusing on pure foods such as raw fruits and vegetables, whole grains, legumes, raw nuts and seeds, fish, vegetable oils, herbs and herbal teas, water, etc.

·      Raw foodism

·      Fasting, including water fasting and juice fasting

·      Increased consumption of fish

·      Food combining

·      Calorie restriction

·      Herbal detox

·      Master Cleanse, also known as the lemonade diet, terms coined to refer to the fasting paradigm penned by Stanley Burroughs

Some proponents of detox diets would emphasize it as a lifestyle, rather than a diet. Literary references include "Ultimate Lifetime Diet" by Gary Null advocating veganism as a (lifestyle) method of detoxification.
