A clear liquid diet is a type of mechanically altered diet that includes only liquids without any pulp, bits of food, or other residue. They may have a tint (like orange juice or cranberry juice), and they may be sweetened or a little salty, but you shouldn't see anything floating around in the liquid.
Liquid diets are hard to sustain for the long term. One specific liquid diet doesn't exist. Many variations of a very-low-calorie diet that has you subsist on juice, clinically prepared nutritional drinks, smoothies, or concoctions of cayenne pepper and lemon juice for days, weeks or even months persist, however.
