Although the clear liquid diet may not be very exciting, it does fulfill its purpose. It's designed to keep your stomach and intestines clear, limit strain to your digestive system, but keep your body hydrated as you prepare for or recover from a medical procedure.

Risks

Because a clear liquid diet can't provide you with adequate calories and nutrients, it shouldn't be used for more than a few days. Only use the clear liquid diet as directed by your doctor.

If your doctor prescribes a clear liquid diet before a medical test, be sure to follow the diet instructions exactly. If you don't follow the diet exactly, you risk an inaccurate test and may have to reschedule the procedure for another time.
