The ketogenic diet is a low-carbohydrate, high-fat, and moderate-protein diet that has gained popularity for weight loss and increased energy. While it has been used since the 1920s to treat epilepsy, its effectiveness for weight loss is not yet known, and there are some health concerns associated with the diet, including an increased risk of constipation due to a lack of fiber-rich foods. Fiber is crucial for digestive health, and keto dieters often experience constipation, especially when they are not properly hydrated. However, fiber is often lacking in keto diets as many high-fiber foods like fruits, starchy vegetables, and whole grains are restricted. Despite this, it is important for those on keto to ensure they are consuming adequate fiber, and this can be achieved by including fibrous foods like nuts, green vegetables, and artichokes in their diet.
| Characteristics | Values |

| What is a keto diet? | A very low-carbohydrate, high-fat, moderate-protein diet that puts your body into a metabolic state called ketosis. |
| What is ketosis? | A natural metabolic state in which the body burns fat instead of glucose for energy. |
| What are net carbs? | The grams of total carbohydrates in a food minus its grams of total fiber. |
| Why are net carbs important? | Fiber is a carbohydrate that the body cannot digest, so it does not count towards the amount of carbs that can trigger an insulin response. |
| How many carbs are allowed on a keto diet? | Generally, between 20 to 50 grams of net carbs per day. |
| What are good sources of fiber on a keto diet? | Nuts, artichokes, fermented foods, green vegetables (e.g., broccoli, cauliflower, zucchini), and low-carb fruits like berries. |
| What are the concerns with a keto diet and fiber intake? | Constipation is common due to the diet's low fiber content. There may also be an increased risk of high cholesterol, heart disease, nutrient deficiencies, and kidney problems. |
| How to get enough fiber on keto? | Include fibrous foods like green vegetables to aid digestion and promote a feeling of fullness. Stay hydrated by consuming high-water-content foods like lettuce, watermelon, apples, and tomatoes. Consult a registered dietitian to ensure nutrient needs are met. |

What You'll Learn
Fiber is important for gut health and digestion
Fiber is a type of carbohydrate that the human body cannot digest. It is found in plant-based foods, particularly beans, nuts, fruits, and vegetables. There are two types of fiber: soluble and insoluble.
Soluble fiber dissolves in water and creates a gel-like substance that slows the movement of food through the digestive tract. This slower digestion reduces blood sugar spikes, lowers blood cholesterol, and helps you feel fuller for longer. Insoluble fiber, on the other hand, does not dissolve in water. Instead, it attracts water into the stool, making it softer and easier to move through the digestive system. This type of fiber is found in the skin and structure of fruits and vegetables, giving them their crunchy texture.
Fiber is essential for maintaining a healthy gut and promoting proper digestion. It supports a healthy gut microbiome, which is crucial for overall health. A healthy gut microbiome is associated with a reduced risk of various diseases, including obesity, type 2 diabetes, cardiovascular disease, and certain cancers. Additionally, fiber helps regulate bowel movements, preventing constipation and promoting regularity.
When following a keto diet, it is important to ensure adequate fiber intake. Keto is a high-fat, low-carbohydrate diet, and as fiber is a type of carbohydrate, it may be lacking in this type of diet. However, fiber is crucial for gut health and digestion, so including fiber-rich foods in your keto meal plan is essential.
Some keto-friendly sources of fiber include nuts, such as pecans and almonds; vegetables like broccoli, cauliflower, and Brussels sprouts; and low-carb, high-fiber foods like konjac root. By incorporating these foods into your keto diet, you can support a healthy gut and promote proper digestion while still adhering to the keto guidelines.

Keto diets are low in fiber-rich foods
The keto diet is a low-carbohydrate, high-fat, and moderate-protein diet. It typically comprises 70 to 75 percent fat, 20 to 25 percent protein, and 5 to 10 percent carbohydrates. The focus on fat and protein means that keto diets are often low in fiber-rich foods.
The keto diet restricts carbohydrate intake so that the body enters a metabolic state called ketosis, where it becomes more efficient at burning fat for energy. Net carbs, calculated by subtracting fiber from total carbohydrates, are what matter when it comes to keto. Fiber is not "counted" in the total carbohydrate intake because it is a carbohydrate that the human body cannot digest.
Fiber is important for gut health and digestion. A lack of fiber can lead to constipation, which is a common side effect of the keto diet. This is especially true at the beginning of the diet when the body is adjusting to a new way of eating. In addition to a lack of insoluble fiber, dehydration can also contribute to constipation, as the diet often involves cutting out fruits and some vegetables, which are hydrating foods.
To ensure adequate fiber intake while on a keto diet, it is recommended to include fiber-rich foods such as nuts, broccoli, cauliflower, Brussels sprouts, and other vegetables in the Brassicaceae family. Artichokes are another good option, as are fermented foods like sauerkraut, which is packed with probiotics and low in carbohydrates.

Keto dieters often experience constipation
The keto diet is a low-carbohydrate diet that centres on protein and fat. Carbohydrates are one of the three macronutrients that our bodies are designed to digest, and they play an important role in health. When you follow the keto diet, your carbohydrate intake is drastically reduced, which can lead to digestive issues like constipation.
Additionally, many keto dieters experience constipation when they start because they are also lacking water. Most people get about 20% of their water intake from the foods they eat, and keto dieters often cut out fruits and lower their intake of certain vegetables, which can lead to dehydration.
To prevent constipation on the keto diet, you can introduce the diet gradually, starting with a higher daily carb intake and slowly reducing it as your digestive system adjusts. You can also try to ""bulk up" meals with fibrous foods like green vegetables, which can help you feel full and satisfied. Eating enough fibre can also help lower cholesterol and promote better blood pressure. Some good sources of keto-friendly fibre include nuts, broccoli, cauliflower, brussels sprouts, and other vegetables in the Brassicaceae family.

Nuts, artichokes, and green vegetables are good fiber sources
The keto diet is a very low-carb diet that replaces most of the usual carb intake with fat. This puts your body into a metabolic state called ketosis, which makes it more efficient at burning fat for energy. While the keto diet is excellent for losing weight and feeling energetic, it can cause some side effects, especially for beginners. One common issue is constipation, which can be caused by a lack of fibre in the diet.
Nuts, artichokes, and green vegetables are good sources of fibre and can help prevent constipation. Nuts are also a great source of healthy fats and protein. When choosing nuts to add to your diet, go for options that are lower in carbs, such as pecans and almonds. Artichokes are not only high in fibre but also packed with vitamins C and K, calcium, and folate. They are also a good source of magnesium, which regulates blood pressure and supports bone health.
Green vegetables, such as broccoli, cauliflower, Brussels sprouts, and other vegetables in the Brassicaceae family, are excellent sources of fibre and are very low in carbohydrates. Broccoli is high in vitamin C, while cauliflower is a versatile addition to many dishes. Other green vegetables that are high in fibre include kale, collard greens, and green peas. These leafy greens are also packed with vitamins and antioxidants, contributing to good health.
By including these fibre-rich foods in your keto diet, you can help ensure you are getting enough fibre, which is crucial for a healthy gut and digestive system.

Fiber doesn't count towards net carbs
The keto diet is a very low-carb diet in which most of the usual carb intake is replaced with fat. This drastic reduction in carb intake puts the body into a metabolic state called ketosis, which makes it more efficient at burning fat for energy. Net carbs are central to the keto diet, and these are calculated by subtracting the grams of total fibre from the total grams of carbohydrates.
Fiber is a type of carbohydrate that the body cannot digest, and so it does not count towards the amount of carbs that can trigger an insulin response. This is important because too much insulin can prevent the body from reaching the ketosis state.
Fiber is crucial for a healthy gut biome and digestion, and a lack of fiber can lead to discomfort. Keto is a high-fat diet, so it is common to experience heartburn and acid reflux as the body adjusts to this new way of eating, especially if the diet is lacking in fiber-rich foods. Many keto dieters experience constipation, especially at the beginning, because they are not only lacking insoluble fiber but also water.
Fiber can be added to the keto diet through nuts, such as pecans and almonds, which are lower in carbs. Nuts can be pureed into a buttery dip for carrots and pepper strips, or eaten as a quick snack. Broccoli, cauliflower, and Brussels sprouts are also excellent sources of fiber and are very low in carbohydrates.
