A detox diet is a dietary regime 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. 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.
