When is the Clear Liquid Diet Advisable?

10. Risks

A short-term liquid diet is generally safe if the individual closely follows the guidelines prescribed by their health care provider. Extending this regimen beyond the recommended length makes a person vulnerable to damage to digestive tract, kidney or liver problems, hypoglycemia, a weakened immune system, and weight gain following the diet. Due to the low nutritive and caloric load of the clear liquid diet, use this regimen only under the advice of a physician.
