A full liquid diet is made up only of fluids and foods that are normally liquid and foods that turn to liquid when they are at room temperature, like ice cream. It also includes strained creamy soups, tea, juice, Jell-O, milkshakes, pudding, and popsicles.
You can NOT eat solid foods when you are on a full liquid diet.
This diet is easier to digest than solid food. It gives you the proteins, fluids, salts, and minerals that you need for energy.
For most people on a full liquid diet, the goal is to get 1,350 to 1,500 calories and 45 grams of protein a day.
Eating only a full liquid diet gives you enough nutrition. You can stay on it for a long time. Your doctor may recommend certain vitamins and supplements. This diet is safe for people with diabetes, but only when they are followed closely by their doctor.
You may need to be on a full liquid diet right before a medical test or procedure, or before certain kinds of surgery. It is important to follow the diet exactly to avoid problems with your procedure or surgery or your test results.
You also may need to be on a full liquid diet for a little while after you have had surgery on your stomach or intestine. You may also need to be on this diet if you are having trouble swallowing or chewing.

Try having a mix of 5 to 7 of the foods you can eat for breakfast, lunch, and dinner.
Liquid foods do NOT include “mashed” foods, such as mashed potato or avocado.
