Liquid diets are low in calories as they have watery fluids. Research in The-American-Journal-of-Clinical-Nutrition showed that very fewer calorie diets, including a liquid diet having no more than 500 calories per day, could be very effective in lowering weight. This type of diet could work well compared to a low-calorie diet or a limited normal food diet.

When you eat fewer calories, your body will begin using more stored glycogen or fat as the fuel source. It could lead to weight loss.

Liquid diets are a good way to detoxify your body. The broths, juices, and smoothies are rich in minerals, vitamins, and dietary fiber. The dietary fiber helps to cleanse the digestive tract and enhance gastrointestinal health. Both these actions could have a good impact on weight loss.



Liquid food in the smoothie or juice form offers rich nutrition. Remember to consume the smoothie or juice instantly if you utilize a centrifugal blender. Returning your dinner meal with low-calorie liquid food improves body composition parameters and may also help in weight loss.

You will have only these options during a complete liquid diet, which can make it difficult to have enough nutrients and calories every day. You will need to follow your physician’s instructions nearly to ensure you are still having all the nutrients your body requires.

A registered nutritionist or dietitian can be a good resource, especially if you get extra dietary restrictions or food allergies.



The complete liquid diet is commonly prescribed for some days to help you change back to a normal diet. It is rarely utilized for longer than two weeks. Exceptions may be allowed for people who are trying for bariatric surgery ( weight loss), recovering from a fractured jaw, or using the diet to manage flare-ups of some health conditions such as Crohn’s disease.

Because of its restrictive nature, you should be monitored by a physician when on a completely liquid diet for more than some days.
