In this comprehensive guide, I am going to explore the relationship between psyllium husk and intermittent fasting and how they can be your allies in achieving a healthier you.

Does Psyllium Husk Break Intermittent Fasting?

If you are using intermittent fasting for weight loss, you can rest assured that psyllium husk will not break your fast. 

Psyllium husk is considered a safe dietary supplement that does not contain enough calories to disrupt your calorie deficit when used as directed. 

Intermittent fasting is simply a different schedule of eating when it comes to using it for weight loss, it is not magic.

As long as you are maintaining a calorie deficit while intermittent fasting, you will still see results. Plain and simple.

A calorie deficit is the cornerstone of any weight loss plan. It is essential. 

It’s also important to note that the carbohydrates present in psyllium husk come from fiber, not sugar, making it a suitable addition to your fasting routine if you are also looking to decrease carbohydrate intake.

Psyllium fiber will not cause an unwanted insulin response or insulin spike.

Not to mention, psyllium husk could also help control any digestive issues you have or might get when starting a new diet plan or decreasing calories.

Using psyllium husk can keep you feeling full when in a fasting window for longer periods for best results with intermittent fasting and controlling calorie intake.

What Is Psyllium Husk?

To truly understand how psyllium husk can complement your intermittent fasting journey, it’s essential to grasp what psyllium husk is and where it comes from.

Psyllium husk is a soluble fiber derived from the seeds of the Plantago ovata plant, primarily cultivated in India. 


This natural remedy has a rich history of use in traditional medicine for its remarkable digestive benefits.

Psyllium can help relieve both constipation and diarrhea, and is commonly used to treat irritable bowel syndrome, hemorrhoids, and other intestinal problems many individuals may have.

You might have heard of Metamucil before I am sure. 

Metamucil is just one of many psyllium husk dietary supplements that works by absorbing water in the digestive tract, forming a gel-like substance that softens stool and makes it easier to pass. 

Metamucil products can be a valuable addition to your daily routine, aiding in the prevention of constipation and supporting overall gut health. 

Additionally, Metamucil has the potential to help with weight management by increasing the feeling of fullness, especially during a fasting period and reducing overeating during your intermittent fasting eating window. 

However, there are other kinds you may have seen. Let’s get into them.
