Is Metamucil Keto Friendly?

When following a ketogenic diet, it is essential to carefully consider the foods and supplements you consume. Metamucil, a popular fiber supplement, is often used to promote regularity and support digestive health. However, if you are on a keto diet, you may wonder if Metamucil is keto-friendly. In this article, we will explore the nutritional composition of Metamucil, its impact on ketosis, and provide valuable insights to help you make an informed decision.

The Nutritional Composition of Metamucil

Metamucil is a fiber supplement that contains psyllium husk, a soluble fiber derived from the seeds of the Plantago ovata plant. It is available in various forms, including powder, capsules, and wafers. The primary purpose of Metamucil is to increase fiber intake, which can help regulate bowel movements and support overall gut health.

Let’s take a closer look at the nutritional composition of Metamucil:

  • Calories: Metamucil contains a minimal amount of calories, typically ranging from 10 to 30 calories per serving, depending on the specific product.
  • Carbohydrates: Metamucil is primarily composed of carbohydrates, with each serving containing around 4 to 6 grams of total carbohydrates.
  • Fiber: The main component of Metamucil is fiber. Each serving typically provides around 3 to 5 grams of dietary fiber.
  • Sugar: Metamucil products are generally low in sugar, with less than 1 gram of sugar per serving.
  • Fat: Metamucil is virtually fat-free, containing negligible amounts of fat.
  • Protein: Metamucil is not a significant source of protein, with only trace amounts present.

Impact on Ketosis

One of the primary goals of a ketogenic diet is to enter a state of ketosis, where the body relies on fat for fuel instead of carbohydrates. To achieve and maintain ketosis, it is crucial to limit carbohydrate intake and increase fat consumption. While Metamucil does contain carbohydrates, the amount is relatively small, and the fiber content can be subtracted from the total carbohydrate count.

Fiber is a type of carbohydrate that is not digested by the body and does not significantly impact blood sugar levels. Therefore, it is often subtracted from the total carbohydrate count when calculating net carbs, which are the carbohydrates that affect ketosis. Net carbs are calculated by subtracting the grams of fiber from the total grams of carbohydrates.

For example, if a serving of Metamucil contains 5 grams of total carbohydrates and 3 grams of fiber, the net carbs would be 2 grams (5 grams – 3 grams = 2 grams). This means that consuming Metamucil in moderation is unlikely to kick you out of ketosis, as long as it fits within your daily carbohydrate limit.

Benefits of Metamucil on a Keto Diet

While Metamucil does contain carbohydrates, it also offers several potential benefits that can support your ketogenic journey:

  • Increased Fiber Intake: Metamucil is an excellent source of dietary fiber, which is often lacking in a typical ketogenic diet. Increasing fiber intake can help promote regular bowel movements, prevent constipation, and support overall gut health.
  • Improved Digestive Health: The soluble fiber in Metamucil can act as a prebiotic, providing nourishment for beneficial gut bacteria. This can help maintain a healthy gut microbiome, which is essential for optimal digestion and overall well-being.
  • Reduced Hunger and Improved Satiety: Fiber-rich foods and supplements like Metamucil can help increase feelings of fullness and reduce hunger cravings. This can be particularly beneficial when following a calorie-restricted ketogenic diet.


1. Can I take Metamucil while on a keto diet?

Yes, you can take Metamucil while on a keto diet. It contains a small amount of carbohydrates, but the fiber content can be subtracted from the total carbohydrate count when calculating net carbs.

2. How much Metamucil can I consume on a keto diet?

The amount of Metamucil you can consume on a keto diet depends on your individual carbohydrate limit. It is recommended to start with a small serving and gradually increase as tolerated.

3. Can Metamucil affect blood sugar levels?

Metamucil is generally low in sugar and does not significantly impact blood sugar levels. However, if you have diabetes or any other medical condition, it is advisable to consult with your healthcare provider before adding Metamucil to your diet.

4. Are there any side effects of taking Metamucil on a keto diet?

Metamucil is generally well-tolerated, but some individuals may experience mild digestive discomfort, such as bloating or gas, when first starting to take it. These symptoms usually subside as the body adjusts to the increased fiber intake.

5. Can Metamucil help with weight loss on a keto diet?

Metamucil can potentially aid in weight loss on a keto diet by increasing feelings of fullness and reducing hunger cravings. However, it is important to note that weight loss is a complex process influenced by various factors, and individual results may vary.

6. Are there any alternatives to Metamucil for a keto diet?

If you are looking for alternatives to Metamucil on a keto diet, you can consider other sources of dietary fiber, such as chia seeds, flaxseeds, or psyllium husk powder. These options can provide similar benefits without adding significant carbohydrates to your diet.


Metamucil can be considered keto-friendly when consumed in moderation. While it does contain carbohydrates, the fiber content can be subtracted from the total carbohydrate count when calculating net carbs. Metamucil offers several potential benefits, including increased fiber intake, improved digestive health, and reduced hunger. However, it is essential to consider individual carbohydrate limits and consult with a healthcare provider if you have any underlying medical conditions. By incorporating Metamucil into your ketogenic diet, you can support your digestive health and overall well-being.
