A liquid diet is a short-term nutritional strategy that includes liquids and foods that become liquid at room or body temperature. It is usually prescribed for a few days to two weeks to help transition to a normal diet, aid recovery from medical procedures, or manage chronic conditions. A clear liquid diet consists of easily absorbed clear liquids, while a full liquid diet offers more flavour and nutrition and includes thicker liquids and pureed foods. Long-term liquid diets are challenging due to the risk of malnutrition and require careful planning with a healthcare provider or dietitian to ensure adequate nutrition. Nutritional supplements and multivitamins may be necessary to prevent nutritional deficits.

It is usually prescribed for short periods to help people recover from gastrointestinal procedures, reduce inflammation, or manage chronic conditions. The aim is to provide adequate nutrition without placing stress on the digestive tract.

For example, people who have had stomach surgery may need to follow a full liquid diet for a period to aid their recovery. It is also sometimes prescribed for those who have difficulty swallowing or chewing.
The diet includes liquids and foods that become liquid at room or body temperature, such as clear broths, pulp-free juices, milk, shakes, smoothies, and soups. It is important to focus on consuming a variety of nutritionally dense foods to meet the nutritional goals of the diet.
If a full liquid diet is followed for longer than a few days, it is important to be closely monitored by a healthcare provider. Nutritional supplements or a liquid multivitamin may be recommended to prevent nutritional deficits and constipation.

It can be challenging to get enough nutrients, so supplements may be needed
A liquid diet typically refers to a full liquid diet, which includes liquids and foods that turn to liquid at room temperature, like ice cream, frozen yogurt, and creamy soups. This is in contrast to a clear liquid diet, which includes only clear liquids such as water, tea, and broth. A full liquid diet is typically prescribed for a few days to help transition back to a normal diet, and rarely for longer than two weeks.

It may also be recommended for those with swallowing difficulties or chronic conditions like Crohn's disease.
It can be challenging to get enough nutrients on a full liquid diet, especially long-term. These diets are typically low in vitamin A, iron, vitamin B-12, and thiamine.

Nutritional supplements are generally recommended for those on a full liquid diet for longer than five days. Liquid multivitamins are one option to ensure adequate nutrition.
To meet nutritional goals on a full liquid diet, it is important to focus on both the quantity and quality of food consumed. As a general rule, eat enough to feel satisfied, and eat several smaller meals throughout the day instead of three big ones. The diet should include a variety of six to eight different foods that are nutritionally dense. It can be challenging to get enough protein and fiber on a full liquid diet, so nutrient-dense foods should be prioritized.
