Is Constipation a Side Effect of Keto Diet?

Is Constipation a Side Effect of Keto Diet?

In recent years, the ketogenic diet has gained popularity for its potential health benefits, including weight loss and improved blood sugar control. However, like any dietary change, there can be some side effects. One potential side effect that many individuals experience when starting a keto diet is constipation. Constipation is characterized by infrequent bowel movements and difficulty passing stool. In this article, we will explore the reasons why constipation may occur on a keto diet and provide tips to alleviate this uncomfortable side effect.

Why Does Constipation Occur on a Keto Diet?

On a standard Western diet, carbohydrates make up a significant portion of daily calorie intake. However, the keto diet drastically restricts carbohydrate consumption and replaces it with high amounts of fat. This shift in macronutrient balance can affect digestion and bowel movements, leading to constipation.

When you consume fewer carbs, your body enters a state of ketosis, where it relies on fat for energy instead of carbohydrates. While in ketosis, your liver produces ketones, and your body flushes out excess fluids, which can cause dehydration. Dehydration is a known contributor to constipation, as it can lead to harder stools that are difficult to pass.

Furthermore, the high-fat nature of the keto diet can slow down the movement of food through the digestive system. This delay in transit time can increase the amount of water absorbed from the stool, making it harder and drier. Combined with the reduced fiber intake that comes with limiting carbohydrates, it’s no wonder that constipation can be a common side effect of the ketogenic diet.

The Role of Fiber in the Keto Diet

Fiber plays a crucial role in maintaining regular bowel movements and overall gut health. Unfortunately, the keto diet tends to be low in fiber due to the restriction of high-carb foods like fruits, whole grains, and legumes. This lack of fiber can contribute to constipation.

It is important to focus on incorporating low-carb, high-fiber foods into your ketogenic meal plan. Some examples include non-starchy vegetables like broccoli, spinach, and kale. Chia seeds, flaxseeds, and avocados are also excellent sources of fiber that can help promote regular bowel movements.

In addition to increasing your fiber intake, it is crucial to stay properly hydrated on a keto diet. Drinking enough fluids, especially water, can help soften the stool and improve digestion. Aim to drink at least 8 cups of water per day and consider adding electrolytes if you are experiencing keto flu symptoms.

Managing Keto Constipation

If you are experiencing constipation on a keto diet, there are several strategies you can try to alleviate this uncomfortable side effect:

  1. Increase your fiber intake: As mentioned earlier, incorporate low-carb, high-fiber foods into your diet to promote regular bowel movements.
  2. Stay hydrated: Drink plenty of water throughout the day to prevent dehydration and keep your stools soft.
  3. Exercise regularly: Physical activity can help stimulate bowel movements and improve overall digestion. Try incorporating regular exercise into your routine.
  4. Add healthy fats: While the keto diet is high in fat, not all fats are created equal. Opt for healthy fats like avocados, nuts, and olive oil, which can promote regular bowel movements.
  5. Consider supplements: If dietary changes and lifestyle modifications are not providing relief, you may want to consider supplements like psyllium husk powder or magnesium citrate to help with constipation.
  6. Consult a healthcare professional: If constipation persists despite trying these strategies, it is important to consult with a healthcare professional for further evaluation and guidance.


Constipation can be a frustrating side effect of the ketogenic diet. However, by understanding the reasons why it occurs and implementing some lifestyle modifications, it is possible to alleviate this discomfort. Increasing fiber intake, staying hydrated, exercising regularly, and considering supplements can all contribute to better bowel movements on a keto diet. Remember to consult with a healthcare professional if constipation persists or becomes severe. With a few adjustments, you can enjoy the benefits of the ketogenic diet while minimizing the side effects.

Frequently Asked Questions

Welcome to our Frequently Asked Questions section about the side effects of the keto diet. Here, we’ll address common concerns and provide answers to help you navigate your keto journey with ease.

1. Why does constipation occur during the keto diet?

Constipation can be a side effect of the keto diet due to a few reasons. Firstly, the diet involves a significant reduction in carbohydrate intake, which can decrease fiber consumption. Fiber plays a crucial role in maintaining regular bowel movements. Moreover, the higher intake of protein and fat on the keto diet may slow down digestion, leading to constipation.

To help alleviate constipation, it’s essential to ensure you’re consuming enough fiber-rich foods such as non-starchy vegetables, avocados, and nuts. Additionally, drinking plenty of water throughout the day can aid in softening the stool and promoting regular bowel movements.

2. Are there any ways to prevent or relieve constipation on the keto diet?

Yes, there are steps you can take to prevent or relieve constipation while following the keto diet. Increasing your fiber intake is one of the most effective methods. Focus on consuming low-carb, fiber-rich foods such as leafy greens, berries, and chia seeds. These not only help with digestion but also provide essential nutrients.

Staying hydrated is also crucial. Be sure to drink enough water throughout the day to support digestion and overall bowel regularity. If constipation persists, you can consider adding a fiber supplement like psyllium husk or try adding natural laxative foods like prunes or flaxseeds to your diet.

3. Can certain keto-approved foods help alleviate constipation?

Yes, incorporating specific keto-friendly foods into your diet can help alleviate constipation. Avocados, for example, are not only rich in healthy fats but also contain significant amounts of fiber. Chia seeds are another excellent option, as they are low in carbs but high in fiber, aiding in digestion and promoting regular bowel movements.

Furthermore, non-starchy vegetables like spinach, broccoli, and cauliflower can provide fiber and promote bowel regularity. Including these foods in your meals and snacks can help prevent or alleviate constipation while following the keto diet.

4. Can I use over-the-counter laxatives to relieve constipation on the keto diet?

While over-the-counter laxatives can provide temporary relief, they are not an ideal long-term solution for constipation during the keto diet. These laxatives can potentially disrupt the natural balance of your gut and may cause dependency over time.

If you’re experiencing persistent constipation, it’s advisable to consult with a healthcare professional who can provide personalized guidance and suggest appropriate solutions. They can help identify the underlying causes and recommend dietary adjustments or supplements specific to your needs.

5. Are there any other side effects of the keto diet I should be aware of?

Yes, there are a few other side effects that can occur during the initial stages of the keto diet. These include the keto flu, which may cause fatigue, headache, and irritability, as well as bad breath and changes in bowel movements. However, with proper hydration, electrolyte balance, and gradually transitioning into the diet, many people find that these side effects diminish over time.

It’s important to remember that everyone’s body is unique, and individual experiences may vary. If you have any concerns or experience severe side effects, it’s always best to consult with a healthcare professional for personalized advice and support.



Feeling constipated on the keto diet? Don’t worry, it’s a normal side effect. The low-fiber nature of the diet can slow down your digestion, leading to constipation. But there are ways to relieve it! Drink lots of water, include more fibrous vegetables, and consider a magnesium supplement.
