Should U Continue Fiber on a Clear Liquid Diet
What Is A Clear Liquid Diet?
A clear liquid diet is a nutrition plan that consists of clear liquids such as water, apple juice, tea, certain sports drinks and broths (1). This eating pattern is designed to keep the stomach and intestines clear prior to medical tests, procedure or surgery. Clear liquids are typically easy to digest and do not leave much-undigested material in your intestines (6). Dietitians may prescribe a full liquid diet for similar reasons, but it is less restrictive than a clear liquid diet. They allow most beverages, as well as foods that become liquid at room temperatures, such as popsicles, Jell-O, pudding, syrups and some shakes (4). Note, however, that such diets should only be followed if prescribed by a doctor!
How Long Can You Be On A Clear Liquid Diet?
This diet is extremely low in calories and nutrients that's why it should not be followed for more than 3-5 days. Following a liquid diet for an extended period of time could increase your risk of nutrient deficiencies, particularly if you are only consuming juices or other beverages that do not contain all essential nutrients ( 2 ). Meanwhile, medically prescribed liquid diets are considered safe for short-term use, but they are typically ordered by a physician ( 1 , 4 ).
Why You May Need To Follow This Diet?
Usually, doctors prescribe this diet before certain medical tests or procedures (colonoscopies, sigmoidoscopy, x-rays). Besides, they may be prescribed after such surgeries as gallbladder removal and bariatric surgery ( 9 ). It's important to follow this diet precisely when it's prescribed to get accurate test results and avoid any problems with an upcoming surgery or procedure. Also, doctors may advise sticking to this diet to relieve digestive problems such as abdominal distention, diarrhea, nausea, etc. This diet can help not only clean out the intestinal tract but can keep you hydrated and provide you with sufficient vitamins and minerals.

This may include nausea, fever, severe abdominal pain, bloody bowel movements, abscess, etc. The right diet can ease the symptoms of the disease. Usually, a nutrition plan for diverticulitis consists of low fiber foods. A physician may even recommend a no-fiber, clear liquid diet to give the gut a rest while it heals. However, this should be discussed with your doctor.

Risks
This diet cannot provide your body with all essential nutrients, vitamins, and minerals. Following this diet for a long time may lead to malnourishment, that's why dietitians do not recommended to follow it for more than 3-5 days. This nutrition plan is especially risky for people with:
- nutritional or electrolyte imbalances
- eating disorders
- endocrine disorders
Clear Liquid Diet And Weight Loss
This nutrition plan is not a safe and effective option for weight loss and it should only be followed if prescribed by a doctor. Since clear liquid diets don't involve any solid foods it won't provide all the beneficial nutrients found in whole foods like fruits and vegetables ( 5 ). Like any crash diet, it doesn't give long-term results and once you get back to a regular diet it leads to weight regain as your carbohydrate and water stores are replenished ( 7 ). Short-term crash diets don't typically lead to lasting weight loss because they don't do anything to change your permanent eating habits ( 8 ).
Moreover, people who stick to this eating pattern for a long time without medical reason can suffer from a range of symptoms like:
- headaches
- mood swings
- weakness
- infertility
- muscle pain
- bone damage
- heart problems
- severe hunger pains
- diarrhea
A more appropriate goal is to incorporate simple strategies that you can use every day for a long period of time, rather than short-term quick fixes that fall short on their promises ( 8 ).

- Drink plenty of water to stay hydrated during the day and suppress hunger pangs
- Eat a variety of flavors like sweet gelatin and salty electrolyte drinks

Clear Liquid Diet And Diabetes
This diet is considered to be safe for people with diabetes for a short time under a doctor's care. P eople with diabetes are usually allowed to eat about 200 grams of carbs to control their blood sugar. If you have diabetes, always monitor your blood sugar levels and get back to your usual diet as quickly as possible. Patients who follow a clear liquid diet can experience dangerous blood sugar swings, if a doctor does not monitor them. According to the University of Gastroenterology, people with diabetes should adjust the dose of their diabetic medication and insulin to prevent blood sugar levels from dropping below normal. Discuss it with your primary care doctor or endocrinologist. Note, in case of any abdominal cramps or discomfort while following this eating plan, notify a doctor right away. Your physician will adjust the diet to reduce hunger pangs, cravings and prevent side effects.
