The Day of the Procedure. You should not eat any food on the day of the procedure, and you shouldn't eat or drink anything between two or three hours before your colonoscopy. Once the procedure is finished, your doctor will give you instructions about resuming your normal diet.
Cold beer in a glass. Before a colonoscopy, the large intestines must be emptied to allow clear visibility and be void of obstructions. A clear liquid diet is usually required for one to two days before the procedure.

Follow your doctor's instructions to ensure your colonoscopy results are accurate and the procedure does not have to be repeated.
