Diet - full liquid

Alternate Names

Full liquid diet

Definition

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.

Why You May Need This Diet

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.

What You Can Eat and Drink

You can eat or drink only things that are liquid. You may have these foods and drinks:

  • Water
  • Fruit juices, including nectars and juices with pulp
  • Butter, margarine, oil, cream, custard, and pudding
  • Plain ice cream, frozen yogurt, and sherbet.
  • Fruit ices and popsicles
  • Sugar, honey, and syrups

  • Sodas, such as ginger ale and Sprite
  • Gelatin (Jell-O)

Ask your doctor if you can include these foods in your full liquid diet:

  • Cooked, refined cereals, such as Cream of Wheat, cream of rice, oatmeal, grits, or farina
  • Strained meats, like the ones in baby food
  • Potatoes pureed in soup

Do NOT eat any kind of cheese, fruit (fresh, frozen, or canned), meat, and cereals that are not on your “okay” list.

Also, do NOT eat raw or cooked vegetables. And, do NOT eat ice cream or other frozen desserts that have any solids in them or on top – things like nuts, chocolate chips, and pieces of cookies.

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.

Adding More Calories

If you need to be on a full liquid diet for a long time, you can do some things to get more calories. Ask your doctor if you can eat these foods together to add calories:

  • Nonfat dry milk added to your drinks
  • Instant breakfast powder added to milk, puddings, custards, and milkshakes
  • Strained meats (like the ones in baby food) added to broths
  • Butter or margarine added to hot cereal and soups
