Some liquid diets are limited to fruit or vegetable juices, or shakes, that replace all of your meals, taken three or four times a day.

Liquid Diet

Liquid Diet

A liquid diet means eating or drinking foods that are liquid. It also means eating foods that will become liquid at room temperature. The diet may be used for short term such as a transition step between the clear liquid and soft diet following gastrointestinal surgery or procedures. It may also be appropriate for those with certain swallowing and chewing problems. This diet should not be used if you are trying to lose weight.

What Are Liquid Diets?

Like the name suggests, liquid diets mean you’re getting all, or at least most, of your calories from drinks. Some liquid diets are limited to fruit or vegetable juices, or shakes, that replace all of your meals, taken three or four times a day. You do some of these diets on your own. Others need medical supervision. Other types of liquid diets replace just one or two meals (usually breakfast and lunch) with drinks, and then you eat a healthy dinner. You may also get snack bars on some of these plans.

Do Liquid Diets Really Work?

Liquid diets contain a reduced and often significantly reduced number of calories. If you eat fewer calories than you burn off, you will lose weight. However, that weight loss may be short-lived. When you drastically reduce the amount of calories you consume, your metabolism slows to conserve energy. Unless you change your eating habits, you’ll gain back the weight as soon as you return to your old diet.


Don’t neglect water as a valuable part of both a clear and full liquid diet. Water and other water-based clear liquid diet foods help maintain hydration, provide the body with electrolytes, and maintain energy when more substantial food can’t fulfill the same tasks.

Enjoy fruit juices

Fruit juice without pulp is acceptable, so you should look for juices like apple juice, grape juice and cranberry juice. Juices that contain pulp, such as some types of orange, grapefruit, or lemon juice, are not acceptable on a clear liquid diet.


Sip plain broth as part of a clear liquid diet. The broth can be canned in a fat-free variety, bouillon or consomme. Broth is more flavorful than many other clear liquid foods, so it helps add variety to the diet.

Pureed Soups

Bisques or pureed soups are another way to add variety and nutrition to a liquid diet. You can make your own by simmering carrots, potatoes, broccoli, cauliflower, asparagus, or other seasonal vegetables in just enough chicken or vegetable stock to cover them. Spice it up with curry powder, ginger, garlic, onion, nutmeg, or fresh herbs. When the vegetables are tender, use an immersion blender to puree until silky. Blend in a dollop of sour cream, a few slices of avocado, silken tofu, or yogurt to add creaminess and extra nutrition.

Healthy Food Options for Liquid Diet

Healthy Food Options for Liquid Diet


Include calcium and protein in your daily full liquid diet by regularly eating and drinking dairy products such as milk, milk-based soups, yogurt, custard and ice cream or frozen yogurt. Though some of these products have high amounts of fat and calories, they provide the body with a greater amount of energy than many other liquid diet foods.
