A etox 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.
