CAUSE DIETS ARE BAD

Liquid diets may work in the short run to rid the body of toxins, but this is not a long-term solution. Chances are high that any weight lost on a liquid diet will quickly be regained.

Full liquid diets often do ease gastrointestinal problems many experience after some surgeries. These types of diets and used to make the transition from clear liquids to solid food and should be followed for a few days or as advised by your doctor.

There really isn't enough research on liquid diets to prove whether they are healthy or unhealthy. From what I researched, information is scarce so I suggest not trying this diet unless approved by a dietician or is well known.
There is a wealth of information available online about the effects of liquid diets. This site shows the results of a Vanderbilt University study, http://www.vanderbilt.edu/ans/psychology/health_psychology/LiquidDiets.htm.
