The keto diet is a very high-fat, low-carb, and moderate-protein eating pattern that induces a phenomenon called ketosis, where the body burns fat instead of glucose for energy. While the keto diet may help burn fat, it can also cause constipation due to the reduced intake of fiber-rich foods like fruits, whole grains, and starchy vegetables. This can lead to digestive issues as fiber is essential for maintaining healthy bowel movements. Additionally, the keto diet may also increase dairy consumption, which can contribute to constipation due to lactose content. However, constipation on keto is usually temporary and can be managed by increasing water intake, consuming more fiber, and making gradual dietary changes.

What You'll Learn
The keto diet is low in fibre, but high in fat and protein
The keto diet is a very high-fat, very low-carb, and moderate-protein eating pattern. This diet involves drastically cutting back on carbs and increasing fat and protein intake. While the keto diet may help burn fat, it can also cause constipation.
The keto diet is typically low in fiber, and individuals following the diet may consume more dairy and drink less water. The combination of these factors can lead to constipation. The keto diet consists mainly of fats and proteins, so you run the risk of under-consuming fiber-rich foods.
Consuming fiber is important. Soluble fiber absorbs water and encourages the movement of food through your digestive tract, while insoluble fiber acts as a bulking agent. A lack of fiber can lead to constipation, as fiber adds bulk to stools by drawing water into the intestines, helping to keep stools soft and bowel movements regular.
However, some sources argue that a lack of fiber does not cause constipation, and that excess dietary fiber may actually be the primary cause. According to a 2012 study, reducing dietary fiber intake can reduce constipation and its associated symptoms. The study found that stopping dietary fiber intake had a strong correlation with reduced constipation.
To prevent and treat constipation while on the keto diet, it is recommended to increase your intake of high-fiber, low-carb foods, such as non-starchy vegetables, berries, and chia seeds. It is also important to drink plenty of water, as dehydration can lead to constipation. Additionally, exercising regularly and avoiding simple carbohydrates can help regulate bowel movements.

Dairy products, which are common in keto diets, can cause constipation
A 2020 study found that people who consumed a lot of dairy had lower levels of butyrate bacteria, which is produced when fibre is broken down and aids digestion. In addition, dairy products are high in fat and low in fibre, which can slow down bowel movements and lead to constipation.
If you suspect that dairy is causing your constipation, try reducing your intake or switching to dairy-free alternatives. Yogurt with probiotics can also help relieve constipation as the live bacteria are good for your digestive system.

Not drinking enough water can lead to constipation
The keto diet is a very high-fat, low-carb, and moderate-protein eating pattern. While it may help burn fat, it can also have side effects, including constipation. Constipation is a common issue for people on the keto diet because of the significant reduction in carbohydrates and fiber-rich foods.
Not drinking enough water can also lead to constipation. Water is essential for digestion, and dehydration can cause constipation by resulting in dry and hard stools that are challenging to pass. The body tries to preserve water when dehydrated, absorbing fluids from the intestines, which dries out the stool. Dehydration can also slow down the movement of stool through the intestines, leading to water reabsorption.
Drinking enough water is crucial for maintaining regular bowel movements. Water keeps food moving through the intestines and ensures the intestines remain smooth and flexible. It acts as a lubricant, helping to pass stool more easily.
To prevent constipation, it is recommended to drink between 8 and 13 cups of water per day. This amount may vary depending on factors such as sex, height, weight, and other individual factors. It is also important to listen to your body and drink water when you feel thirsty.
In addition to increasing water intake, other ways to prevent constipation include adding more fiber-rich, low-carb foods to your diet, such as non-starchy vegetables, berries, and chia seeds. Regular exercise can also help stimulate the muscles in the intestines, improving bowel movements.

Transitioning to keto too quickly can cause constipation
Transitioning to the keto diet too quickly can cause constipation, a common side effect of the diet. The keto diet involves drastically cutting back on carbohydrates and increasing the consumption of fats and proteins. This shift in eating habits can lead to constipation due to the reduced intake of fiber-rich foods, which are essential for regular bowel movements.
The keto diet typically includes less than 50 grams of carbohydrates per day, which means that people on this diet may not be consuming enough fiber. Fiber is important for maintaining regular bowel movements as it adds bulk to the stool and helps the colon work effectively. The keto diet often excludes fiber-rich sources such as fruits, vegetables, whole grains, and legumes.
Additionally, the transition to a keto diet can be challenging for the body to adjust to. The body needs time to adapt to the reduced intake of carbohydrates and the increased intake of fats and proteins. During this transitional period, constipation can occur as the body adjusts its digestive function.
To prevent and relieve constipation when transitioning to the keto diet, it is recommended to:
- Gradually reduce carbohydrate intake over a few weeks, instead of making a sudden drastic change.
- Increase the consumption of high-fiber, low-carb foods such as non-starchy vegetables, berries, and chia seeds.
- Stay properly hydrated by drinking plenty of water.
- Avoid simple carbohydrates and processed foods, which can further disrupt the digestive system.
- Consider taking fiber supplements or laxatives, but consult with a healthcare professional first.
- Exercise regularly to encourage intestinal contractions and improve constipation.

The keto diet can be hard to stick to
Secondly, the keto diet can be psychologically challenging to adjust to. It often involves a lot of planning and calculations to ensure that one stays within the strict limits of carbohydrate, fat, and protein intake. This can be tedious and time-consuming, and most people may not have the energy or motivation to sustain it in the long term. The highly restrictive nature of the diet can also lead to social isolation as it becomes difficult to go out with friends for meals or drinks. It can also be challenging to find keto-friendly options when eating out.
Additionally, the keto diet can be expensive and inconvenient as it requires purchasing specific foods and avoiding others. It may also require cooking at home more often, which can be a burden for those with busy schedules. The diet can also be hard to stick to due to carb cravings. Finally, some people may experience gastrointestinal issues such as constipation when starting the keto diet, which can be off-putting and uncomfortable.
