Liquid diet

A liquid diet is a diet that mostly consists of liquids, or soft foods that melt at room temperature (such as ice cream). A liquid diet usually helps provide sufficient hydration, helps maintain electrolyte balance, and is often prescribed for people when solid food diets are not recommended, such as for people who suffer with gastrointestinal illness or damage, or before or after certain types of medical tests or surgeries involving the mouth or the digestive tract.^[1]

A liquid diet is not recommended outside of hospital or medical supervision. Negative side effects include fatigue, nausea, dizziness, hair loss and dry skin which are said to disappear when the person resumes eating.^[2]
