What is Dietary Fiber?

How Much Fiber Should I Take on a Ketogenic Diet? Fiber Intake!

Consuming enough fiber is essential for overall health, but most people don’t eat enough fiber-rich foods daily even though the recommended amount is between 25grams and 30grams of fiber whether you’re keto or not.

But the problem is that many keto-approved foods aren’t rich-in. That’s why many people decide to take supplements to compensate for the lack of fiber.

Fiber Benefits

Following the ketogenic diet, it’s challenging to get your daily fiber without a carefully-designed meal plan that makes sure you get enough dose.

After all, health specialists have been emphasizing the importance of this carbohydrate for years.

And we’re not talking only about vegetables and plants as fiber sources. Any high-quality supplementation equally helps you improve your overall health, such as:

Tips for Improving Digestion on Ketogenic Diet

You can improve your overall health with regular fiber intake either from the food or low-carb fiber supplement.

Still, this is sometimes not enough to eliminate the gastrointestinal problems as they’re not always caused by the lack of fiber on your plate.

Here are some other tips that can help you improve digestion:

Using Metamucil on Keto? What is It?

Metamucil is a form of Psyllium husk powder. It’s a soluble fiber supplement with a very high concentration of fibers.

It’s very similar to Benefiber, which contains wheat dextrin. On the other hand, Metamucil contains psyllium husk powder.

Still, these two have different effects on the body. If you’re looking for information in Metamucil on keto, you may find this study that reported the supplement successfully improving their levels of cholesterol and insulin.

Still, Benefiber contains less additional ingredients than Metamucil (except its natural form): no sweeteners, colorants, and other ingredients that may not be the best for the healthy ketogenic diet.

Benefiber on the keto diet may be more appropriate, but that is your choice entirely.

Is Metamucil Better Than Benefiber?

Before I get into how Benefiber and Metamucil compare in terms of GI health, I should explain why you want to eat fiber. "If you think about it, fiber is the only thing keeping our bodies in balance," says Dr. Jack A. Fata, an oral surgeon in Miami. "Amount Fiber is what keeps us regular. That's why we need more fiber as we age." That's not to say these supplements can't help with GI issues—they can. But there are some drawbacks. Benefiber, for example, is not a "solution" for constipation, like Metamucil, says Dr. Shannon M. Triggs, director of the Center for Adjuvant and Reconstructive Oral and Maxillofacial Surgery at NYU School of Medicine. "It is great for people who are constipated, as long as they know they're having an episode of it, and they're willing to take the product," she says. (We discuss how to identify and treat a case of constipation in the video below.)

[But] the problem is it is slow to work," says Dr. Francesco Natale, a University of Maryland gastroenterologist. "So if you are taking a fiber product and you are constipated for a few days, you may feel better but it won't necessarily get you to the regular place. If you are constipated for two weeks, you might notice more constipation because fiber is not acting fast enough." Dr. Natale says he likes Metamucil because it "doesn't have this inactive element and it will get you moving more quickly." But where does the issue lie between Benefiber and Metamucil? It's not the fiber that makes Metamucil a popular stool softener. The formula is highly refined and contains 0.5 grams of fiber per serving.

Which Fiber Supplements Is the Best?

Whether you’re on a keto diet or not yet, supplements are a must.

You aren’t able to get enough fiber with your meal plans, yet you need it if you want to maintain a healthy body and lose weight at the same time.

Regular bowel movements are more important than you may think; a healthy gut means a healthy body and it can help you get there.

Yes, other factors can negatively impact your digestion, such as lack of sleep and water.

Make sure to check all the steps double to see if you’re on the right track. In other words, listen to your body.

You can stack up on supplements, but always make sure to eat plenty of food that contains fiber; there is plenty keto-approved for consumption.

Of all the supplements we reviewed, we found the one we think to be the best since it’s practical, affordable, safe to use, and comes from a reliable company.

Our favorite best fiber supplement is by far NOW Psyllium Husk Powder.

It packs all the benefits of a fiber powder yet it’s the easiest to take. It’s also useful for some health issues, such as bloating, digestive problems, diarrhea.
