A clear liquid diet limits you to options such as water, broth and plain gelatin. These are easy to digest, and they don't leave food bits in your digestive tract. Your healthcare professional may prescribe a clear liquid diet before or after some medical procedures or if you have digestive problems such as vomiting or diarrhea. A clear liquid diet can't give you all the calories and nutrients you need. So it generally shouldn't be continued for more than a few days.
Clear liquids may have some color. Liquids with some color are allowed if you can see through them. Foods can be considered liquid if they partly or completely melt to clear fluid at room temperature. You can't eat solid food while on a clear liquid diet.
