The low-residuei XThe undigested food, including fiber, that passes through the intestines after consumption of food. diet is a diet plan based on the principle of consuming low-fiber foods to minimize bowel movements and let the colon rest and heal. This diet focuses on foods that are easy for the body to break down and absorb while limiting the intake of fiber-rich foods like whole grains and certain fruits, vegetables, and seeds. It is commonly prescribed for individuals with gastrointestinal conditions like Crohn’s disease or ulcerative colitisi XInflammation of the inner lining of the colon, which causes pain, bloating, and diarrhea. , or before and after certain digestive surgeries.
However, one should be cautious while following this diet plan, as long-term adherence to it without medical supervision can lead to nutrient deficiencies and constipation. Consulting a healthcare professional is advisable before starting a low-residue diet. Keep reading to further understand how this diet works and some low-fiber diet ideas for effective results.
- Principle: A low-fiber diet that reduces undigested food in the gut after initial digestion.
- Purpose: To reduce residue, ease bowel movements, soothe the intestines, and prepare for medical procedures like colonoscopyi XA medical procedure in which a special tube with a tiny camera is used to look inside the large intestine to check for issues such as polyps or cancer. .
- Who It Is For: People experiencing bloating, cramping, diarrhea, or active digestive flare-ups or those recovering from recent bowel surgery or preparing for a colonoscopy.
- Duration: Short-term

What Is A Low-Residue Diet?
A low-residue diet limits indigestible food components (called ‘residue’) which can make your stools bulkier. This diet typically includes foods like eggs, ripe bananas, refined grains, white rice, seafood, and poultry, while limiting dairy and avoiding high-fiber foods and whole grains. However, defining the exact composition of this diet is challenging due to differences in individual digestion patterns and microbiota, and, therefore, what’s considered ‘residue.’ Additionally, the term ‘low residue’ is sometimes used interchangeably with ‘low fiber,’ even though certain low-fiber foods like milk can lead to high colonic residue (1). Scroll down to the next section to understand how this diet can impact the digestive process.
How Does A Low-Residue Diet Work?
Here’s how the diet functions:
- Reduced Fiber Intake: Fiber is a key contributor to stool volume and frequency (2). Thus, reducing fiber intake may help reduce the same and keep the gastrointestinal tract clean.
- Decreased Stool Quantity: Bowel movements occur less often when there is less residue in the digestive tract.
- Gentle On The Gastrointestinal System: This diet helps minimize irritation and stress in the digestive system for individuals with specific medical conditions or those recovering from digestive surgeries.
A low-residue diet is recommended in various clinical situations, such as bowel preparation before a colonoscopy or colorectal surgery. Studies suggest it can offer better patient satisfaction and equivalent bowel cleanliness before a colonoscopy compared to the clear liquid diet. In fact, people who followed the clear liquid diet experienced more hunger, nausea, and vomiting, while people who followed the low-residue diet had better tolerance during colonoscopy and were more willing to repeat the procedure with less complications (3).
This diet is also recommended during flare-ups of inflammatory bowel diseasei XA set of conditions in which the intestines become inflamed and cause symptoms like pain, diarrhea, and weight loss. , infectious colitis, and acute diverticulitisi XA condition in which the diverticula (small pouches) in the intestines become inflamed or infected, leading to pain. to potentially reduce inflammation by slowing down bowel movements. However, more research is required in this regard.
Now, let’s take a look at how to follow a low-residue diet the right way.
How To Follow A Low-Residue Diet
The main focus of a low-residue diet is to limit the intake of fiber to keep the bowel clean. Thus, you must minimize the consumption of high-fiber foods like seeds, nuts, and whole grains if you want to follow a low-residue diet. Staying well-hydrated is also essential when following this diet to prevent constipation.
Include foods like well-cooked and peeled vegetables, white rice, refined grains, lean meats, poultry, and seafood in your diet. Also, it is crucial to steer clear of spicy foods, raw vegetables, milk, and tough meats.
Since this diet can be restrictive, it is essential to consult with a healthcare professional or dietitian to ensure you are getting the necessary nutrients and to determine the appropriate duration for this diet based on individual health requirements. Check out the section below to know when you can incorporate a low-residue meal plan into your routine.
When Should You Start A Low-Residue Diet?
These are some common scenarios when a low-residue diet may be recommended:
- Pre-Surgical Preparation: Before certain types of gastrointestinal surgeries (like colorectal surgery) to minimize bowel contents and make it easier to empty the bowel pre-surgery.
- Before Medical Procedures: Prior to certain procedures, like a colonoscopy, for a clearer view of the colon.
- Post-Surgical Recovery: After gastrointestinal surgeries to reduce the strain on the digestive system, allowing for a gentler recovery.
- Gastrointestinal Flare-Ups: For individuals with inflammatory bowel diseases, like Crohn’s disease or ulcerative colitis, to give the bowel a rest and reduce symptoms or flare-ups.
- Diverticulitis: During an acute episode of diverticulitis to minimize irritation and inflammation of the intestines and promote healing.

While the low-residue diet can be beneficial to prep your gut before a medical procedure, it does have its fair share of limitations. Learn more about them in the next section.
Limitations Of A Low-Residue Diet
While a low-residue diet can be beneficial for certain medical conditions or situations, it has some limitations to consider. These include:
- May Cause Nutrient Deficiencies
This diet restricts many high-fiber foods, which are rich in essential vitamins, minerals, and antioxidants. This can lead to nutrient deficiencies if the diet is followed for an extended period.
- May Impact Digestive Health
Prolonged adherence to a low-residue diet may negatively affect your long-term digestive health. A lack of dietary fiber can lead to constipation and may increase the risk of certain digestive issues, like colorectal cancer and diverticulosis (5), (6).
- May Affect Gastrointestinal Function
While it is suitable for short-term use for specific medical conditions, a low-residue diet may slow down bowel movements and alter the composition of gut bacteria, thus affecting overall gastrointestinal function. However, more research is needed in this regard.
- May Impact Bowel Regularity
Reducing dietary fiber intake may lead to irregular bowel movements and exacerbate symptoms of diarrhea or constipation in some individuals. However, there is not enough scientific data to prove the same.
- May Cause Weight Gain
Some individuals may experience weight gain on a low residue diet due to the increased consumption of calorie-dense and easily digestible foods. However, more research is required to prove the same.
While a low-residue diet may be good to follow before certain medical procedures, it is important to follow it under the guidance of a healthcare professional.
A low-residue diet limits the intake of fiber and other difficult-to-digest foods to prepare the bowel before certain medical procedures. While it can provide relief and assist in maintaining a clean colon, it is not a permanent dietary solution, as it lacks the fiber and diverse nutrients essential for long-term health. It is best to follow this diet as a temporary measure, then gradually reintroduce high-fiber foods to maintain a balanced and nutritious diet. Always prioritize a well-rounded eating plan that includes a variety of nutrient-rich foods for long-term digestive health and overall well-being. As with any dietary modifications, it is essential that you consult your doctor to ensure a balanced, healthy approach to your diet.

How do you introduce fiber after following a low-residue diet?
After following a low-residue diet, reintroduce fiber into your diet gradually to avoid digestive discomfort. Start with soluble fiber sources like oatmeal and cooked, peeled fruits. Slowly incorporate whole grains by transitioning from white to whole-wheat bread. Increase the portions of legumes and vegetables over time, monitoring for tolerance. Ensure adequate hydration as fiber intake increases, and consult your dietitian for personalized guidance to enable a smooth transition.
