The Ketogenic (or Keto) diet is a popular low-carb, high-fat diet that provides numerous health benefits. Someone may follow a keto diet to lose weight, lower their blood sugar, or manage diseases such as Type 2 Diabetes or Epilepsy.
On a traditional keto diet, 5-10% of your total daily calories are from carbs, 70-80% from fat and 10-20% from protein. A low carb diet puts your body in a metabolic state called ketosis, where fat is burned for energy instead of carbs.
Since the majority of a keto diet is made up of fat and protein (a.k.a. foods that are traditionally low in fiber), getting enough of this nutrient can be challenging.
Can You Eat Fiber On a Keto Diet?
Yes! And you should.
While fiber is technically a carbohydrate, it doesn’t “count” as a carb on a keto diet since it isn’t digested.
There are two types of fiber, which differ in how they interact with the water in your body: soluble and insoluble.
- Soluble fiber dissolves in water, creating a gel like substance which helps slow digestion to keep you feeling fuller, longer. It can also slow the absorption of carbohydrates into the intestines and help control blood glucose levels.
Soluble fiber is predominantly found in fruits and legumes, which are typically high in carbs, and therefore not considered keto-friendly. A small amount of soluble fiber is also found in vegetables.
- Insoluble fiber does not dissolve in water. It mostly serves as a bulking agent for your stool, helping to promote the movement of material through your digestive system.
Insoluble fiber is the predominant type of fiber found in vegetables. It is also found in nuts and seeds.
Your body needs both types of fiber to support healthy digestion and promote overall wellness.
How to get enough fiber on the keto diet
Since most keto-friendly foods contain only insoluble fiber, it takes a little extra effort to make sure you are also getting enough soluble fiber.
