The ketogenic (keto) diet, characterized by its very low carbohydrate and high healthy fat content, has gained significant popularity as a weight loss and health management strategy. An emphasis on nutritious whole foods is an integral part of the keto diet. As the keto diet continues to gain popularity, the importance of fiber in maintaining optimal health and supporting ketosis has become increasingly recognized. This article delves into the role of resistant dextrin within the context of a ketogenic diet, contrasting it with other fiber sources and addressing common misconceptions.
Understanding the Keto Diet
The keto diet involves drastically reducing carbohydrate intake and replacing it with fat. This metabolic shift forces the body to enter a state of ketosis, where it begins to burn fat for fuel instead of glucose. To achieve and maintain ketosis, individuals must carefully monitor their macronutrient intake, ensuring a high fat, moderate protein, and very low carbohydrate consumption.
The Importance of Fiber on Keto
While often overlooked, fiber plays a crucial role in a well-formulated ketogenic diet. Adequate fiber intake supports digestive health, promotes satiety, helps regulate blood sugar levels, and may even enhance the production of beneficial gut bacteria.
Resistant Dextrin: A Keto-Friendly Fiber
In the world of keto-friendly fibers, two prominent players have emerged: resistant dextrin and isomalto-oligosaccharides (IMO). Resistant dextrin, also known as soluble corn fiber, is a type of soluble dietary fiber derived from the processing of tapioca starch or the husks and fiber of vegetables. Unlike many other carbohydrates, resistant dextrin is not readily broken down and absorbed by the human digestive system.
Minimal Impact on Blood Sugar
One of the key advantages of resistant dextrin is its minimal impact on blood sugar levels. Due to its resistance to digestion, resistant dextrin does not significantly raise insulin or blood glucose, making it an ideal choice for those following a keto diet.

Prebiotic Benefits
Resistant dextrin is a prebiotic fiber, which means it actually supports the probiotics in your body. Prebiotic fiber can help improve your gut, help you regulate your glucose levels, and keep you full longer. It can help your body work more efficiently and support your immune system. Soluble corn fiber is also shown in studies to lower cholesterol and can reduce the risk of heart disease.
Resistant Dextrin vs. Maltodextrin
It's important to distinguish resistant dextrin from maltodextrin. Folks sometimes see the word “dextrin” and believe that it simply means maltodextrin. While maltodextrin is made from starch, resistant dextrin is made from corn husk fiber. Maltodextrin is an easily digestible starch that can be absorbed as quickly as sugar, so it’s not good for diabetics or anyone with celiac disease. It can also damage your gut health and immune system. This ingredient is considered high on the glycemic index, so anyone sugar conscious should avoid it. Maltodextrin is high in net carbs while resistant dextrin is low on net carbs.
Resistant Dextrin vs. Dextrin
Dextrin is not the same as resistant dextrin. Dextrin is made with starch and resistant dextrin is made with plant fiber.
Tapioca Resistant Dextrin
When it comes to keto-friendly fiber sources, tapioca-derived options have gained significant attention. Tapioca resistant dextrin, as mentioned earlier, is a highly soluble and low-impact fiber that can be seamlessly incorporated into keto-friendly recipes and supplements.
Isomalto-oligosaccharides (IMOs): A Controversial Fiber Source
Isomalto-oligosaccharides, or IMOs, are a group of carbohydrates that are often marketed as a low-calorie, low-glycemic sweetener and fiber source. While IMOs have been touted for their potential prebiotic benefits and ability to support gut health, their classification as a true dietary fiber has been a subject of ongoing debate.

The FDA's Stance on Tapioca IMO
While some companies will try to claim that soluble tapioca IMO is fiber, it’s actually made out of starch. Starch can greatly affect blood glucose levels and is not friendly to diabetics. That means while soluble tapioca IMO is full of carbohydrates that can kick you out of keto, soluble corn fiber is not and will have no impact on blood sugar levels. The FDA has ruled that tapioca IMO (Isomaltooligosaccharide) must be counted as a carbohydrate and can no longer be cited as fiber. That means there will be less confusion, which is great for reading labels and understanding what goes into the food you eat.
IMOs and Blood Sugar
IMOs are a type of syrup made from starches like corn, potato, or tapioca. IMOs are not suitable for low-carb or keto diets, but actual soluble tapioca fiber is fine.
Incorporating Resistant Dextrin into a Keto Diet
Resistant dextrin can be easily incorporated into a ketogenic diet through various means:
- As a supplement: Resistant dextrin is available in powder form and can be added to beverages or smoothies.
- In keto-friendly recipes: Resistant dextrin can be used as an ingredient in baked goods, bars, and other keto-friendly treats to increase their fiber content.
Other Keto-Friendly Fiber Sources
While resistant dextrin is a valuable addition to a keto diet, it's essential to obtain fiber from a variety of sources. For example, you can use keto-friendly fruits and veggies to get the majority of your fiber.
Potential Benefits of Resistant Dextrin
Beyond its role as a fiber source, resistant dextrin may offer additional health benefits:

- Improved gut health: As a prebiotic fiber, resistant dextrin can promote the growth of beneficial gut bacteria, contributing to a healthy gut microbiome.
- Enhanced satiety: Resistant dextrin can help increase feelings of fullness, which may aid in weight management.
- Improved glucose control: Prebiotic fiber has been known to not only make you feel fuller, it can actually help your body regulate its glucose levels. Diabetic patients who eat prebiotic fiber have found that it’s easier for them to maintain a steady glucose level than without it in numerous studies.
Considerations and Potential Side Effects
While resistant dextrin is generally considered safe, some individuals may experience gastrointestinal discomfort, such as bloating or gas, when consuming it in large quantities. It's best to start with a small dose and gradually increase intake to assess tolerance. Of course, fiber doesn’t work for some people, so we always suggest you ask your doctor when adding a new product to your diet.
