If you’re on the ketogenic diet, you know how much of a pain it is to get the nutrients you normally receive from carbohydrate sources.

One of these “nutrients” is fiber, the all-magical substance that helps…keep you regular.

On top of that, fiber allows your digestion system to move indigestible food from your stomach through your GI tract and beyond.

So even though you don’t consume high-fiber foods in the form of carbs, it’s still vital to get ample amounts of fiber.

Thankfully, there are multiple ways you can solve this problem.

In a hurry? Here are the best keto fiber supplements:

In this article, we’ll go over what fiber is, what it does for you and your body, what a keto fiber supplement is, how to subtract fiber from overall carb count, and ketogenic foods that are actually high in fiber.

We’ll also show you the best fiber supplements on the market that are conducive to a ketogenic lifestyle.

Now, let’s learn about some fiber!

What is a Ketogenic Fiber Supplement?

ketogenic

Essentially, fiber supplements help you maintain a healthy intake of dietary fiber. However, typical fiber supplements are laden with carbohydrates.

Enter ketogenic fiber supplements. These bad boys get you the fiber your body needs to keep you regular, while reducing the amount of carbs found within the product, making it keto-friendly.

Plus, when it comes to the ketogenic diet, some people have issues with their bowels due to the high fat content and low-carb (a.k.a. low-fiber) intake.

With a keto fiber supplement, you’re able to stay regular on the ketogenic diet and avoid the nasty side effects.

What is a Fiber Supplement Used For?

As stated previously, fiber supplements are to make sure your bowels stay happy and healthy.

While most people who use it don’t get enough fiber in their diet just because they eat without any thought, it’s a necessity for those on the ketogenic diet.

Fiber supplements replenish your body’s soluble and insoluble fiber. Soluble fiber attaches itself to water in your digestive system and turns into a gel throughout digestion.

This process helps to slow digestion overall, and soluble fiber is found in a lot of natural foods. INsoluble fiber, on the other hand, does not attach to water.

In fact, it doesn’t attach to anything. Its job is to make the stool bulky. Basically, the things we don’t digest and have to excrete combines with insoluble fiber; the more you have, the easier it is to go to the bathroom (to a point).

Fiber supplements should give you more of both. The trick is to find a supplement that has soluble and insoluble, so that you get the most bang for your buck.

Fiber Supplement BenefitsFiber Supplement

By adding more fiber to your diet in the form of a supplement, you get the following advantages:

  • Normalized bowel movements: Dietary fiber does a lot of things to your bowel movements. It bulks up your stool, while also softening it. The result is a more pleasant bathroom experience than if you were to just “rough it” with the ketogenic diet. Fiber will decrease your chances of constipation, which is a common side effect with going keto.

  • Increased bowel health: Funny enough, your gut has a lot to do with your overall health. With in influx of fiber, you get to steer clear from things like hemorrhoids and diverticular disease, which is this really fun condition where you have pouches on your colon. Seeing as some fiber actually ferments in the colon, it’s possible that fiber can keep your colon and the rest of your GI tract healthy and devoid of disease.

  • Lower cholesterol levels: Fiber also lowers LDL cholesterol, also known as the bad kind of cholesterol. High-fiber foods have also been found to reduce blood pressure and lower inflammation, all related to the heart and your immune system. More fiber = Better internal health.

  • Enhanced blood sugar regulation: When you consume something sugary, your blood sugar tends to spike up, which could eventually lead to excess inflammation, insulin resistance, and even diabetes. Fortunately, if you eat something fibrous with your spike in sugar, the fiber will slow the absorption and will level out your blood sugar.

  • Help with losing or maintaining weight: Fiber is incredibly filling, way more filling than simple sugars or other carbohydrate sources. As a result, you’ll likely eat less and remain full longer. Eating less is one of the major components associated with weight loss and maintaining a healthy body fat percentage. Plus, high-fiber foods and supplements are not calorically dense, meaning you can consume more and intake less calories. Win-win.

These are just a few of the benefits of either eating fibrous foods or taking a ketogenic fiber supplement.

But it’s obvious to see, additional fiber does a lot of good for your entire body, especially when you have to excuse yourself for #2.

How Much Fiber Should I Have on a Keto Diet?

Experts say you should get 30-38 grams per day if you’re an adult male, and 25 grams per day for women who are between 18 and 50 years old. (When past 50 years of age, women only need 21 grams per day.)

On top of that, 10-15 of that amount should be soluble fiber.

On a ketogenic diet, you’ll definitely want to get that much fiber in you every day.

Without a healthy amount of fiber, you will potentially feel the consequences of too little fiber, which could mean constipation, loose stool, and more complications.

Do You Subtract Fiber From Carbs on Keto?

In a traditional ketogenic diet, the rule is less than 50 grams, with a standard range being 20-30 grams or 5% of your total calories.

The term “carbohydrate” means multiple things; carbs can be in the form of sugar (simple carbs), starches (complex carbs), fiber, or oligosaccharides, which fall between sugars and starches.

The main one you want to avoid – to the best of your ability – is sugar. Starches should also be eliminated as much as possible.

However, fiber is considered healthy and even necessary on a ketogenic diet. So, when you count your carbs, it makes sense to check the nutrition label for your foods and subtract the “fiber” content from the overall “carbohydrate” content.

For prepackaged food items, fiber content should be found underneath the total carbs, making this calculation easy.

For natural foods without labels, look up the nutrition profile online to get a good estimation.

So, the short answer is yes, you should subtract fiber from your carbs (your fiber intake will not count toward your daily carb intake).

Don’t be afraid to eat a ton of fibrous foods just because they have carbohydrates in them. In terms of the ketogenic diet, not all carbs are created equal.

Keto Foods That Are High in Fiber

Here are some natural foods that include a decent amount of fiber but don’t have you sweating whether you’ve broken ketosis or not.

These foods are low in sugar and starch, leaving all of their carbs as fiber.

These are the best keto foods for fiber, along with their fiber content per serving:

  • Flax Seeds (2.8g)
  • Chia Seeds (10g)
  • Celery (8g)
  • Lettuce (0.5g)
  • Cabbage (raw or cooked; 0.6g)
  • Raw Coconut (7g for 1 cup shredded, but also has 5g of sugar so be careful)
  • Spinach (2.2g)
  • Avocado (10g)
  • Broccoli (3.8g)
  • Cauliflower (2.1g)
  • Eggplant (2.5g)
  • Asparagus (2.8g)
  • Mushrooms (0.7g)
  • Bell Peppers (2.1g)
  • Radishes (1.9g)
  • Zucchini (1.2g)
  • Tomatoes (2g)
  • Hopefully, you’re implementing a bunch of these into your nutrition plan already.

    But if you aren’t, it’s super easy to throw most of these into stir fries, topping meals with seeds and raw coconut (unsweetened), or simply eating half of an avocado with some sea salt and chile powder.

    The top dogs in terms of fiber vs. sugar content are avocados, spinach, chia seeds, and flax seeds. The others have moderate sugar content, so you’ll need to watch your intake of these foods.

    Too much broccoli or bell peppers could actually kick you out of ketosis….

    …Which is why having a ketogenic fiber supplement is extremely beneficial!

    Fiber Supplement Dosage

    How much fiber do you need a day?

    Well, as we stated earlier, 38g for men and 25g for women seems to be the sweet spot for daily fiber consumption. This will help keep you regular.

    Adjusting for how much fiber you naturally take in, it would make sense to grab a quality fiber supplement that gives you 5-10g per serving, just to help out the natural foods.

    When should you take it?

    You can take your fiber supplement with food, or not. The choice is up to you.

    What isn’t up to you is the water.

    You should drink a glass of water – 8 ounces – with your fiber supplement. This will help the supplement reach the stomach and the GI tract without any hiccups.

    Also, make sure you don’t take your fiber supplement with medication.

    Medication first, then wait an hour and take your fiber supplement then. Otherwise, you can take your fiber supplement whenever, wherever.

    How long does it take to work?

    Regularly, a keto fiber supplement takes 12-24 hours to effect your entire digestive system.

    The best way to go about taking a fiber supplement is to begin your day with the prescribed dosage with 8 ounces of room temperature water with sea salt and lemon juice.

    That way, you’ll have the fiber primed and ready for any ketogenic meals you have throughout the day!

    Fiber Supplement Side Effects

    While it all might sound like sunshine and rainbows with ketogenic fiber supplements, there are always side effects to supplementation. Usually, these won’t occur unless you supplement too much or are abusing them in some sort of way. Nevertheless, it’s good to be prepared.

    Here are the typical side effects from fiber supplements:

    • Flatulence
    • Bloating
    • Diarrhea
    • Cramping
    • Constipation

    Thankfully, you can avoid or limit these unfortunate effects by simply slowly upping your fiber supplementation. Start with half a dose if you notice any of these, then gradually increase until you reach the alloted dose.
