Is Maltodextrin Keto-Friendly?

Maltodextrin on a kitchen counter

Let's pull back the curtain on a question that often puzzles those following a ketogenic diet: Is Maltodextrin Keto-Friendly? The straightforward answer is no.

Given its high carbohydrate content, Maltodextrin finds itself on the 'not recommended' list for those adhering to a low-carb or keto diet.


  • Maltodextrin isn't keto-friendly due to its high carbohydrate content.
  • This high-carb nature disrupts ketosis, making Maltodextrin a poor choice for low-carb diets.
  • Drawbacks of Maltodextrin include a high glycemic index and potential sodium concerns.

Is Maltodextrin Keto-Friendly?

The straightforward answer to this is, no, Maltodextrin is not keto-friendly. Evaluating its nutritional attributes provides a clear picture of why this is so. Maltodextrin contains a high carbohydrate content, with about 94.64g of carbs per 100g. This alone makes it highly incompatible with a typical ketogenic diet, which focuses on low carbohydrate intake.

Can You Have Maltodextrin On a Strict Keto Diet?

In a strict keto diet, where the daily carb limit is typically less than 20g, the inclusion of Maltodextrin is not recommended. Its high carbohydrate content can easily surpass this limit, even in small quantities.

Even for individuals following a less strict keto or low carb diet, where the daily carb limit may range between 30-50g net carbs, consuming Maltodextrin can be problematic. Given its high carb content, even a small serving could significantly contribute to the daily carb quota, leaving little room for other foods.

Carbs In Maltodextrin

Maltodextrin stands out for its high carbohydrate content. Per 100g, it contains around 94.64g of carbohydrates. This means that nearly 95% of its weight is attributed to carbs, a factor that makes it less than ideal for low-carb diets like keto.

Further breaking it down, a typical serving size of Maltodextrin, which is about 2g, holds nearly 1.89g of net carbs. This implies that almost all of its serving size comprises carbohydrates, again emphasizing its high-carb nature.

Maltodextrin Nutrition Facts

Starting with an overall nutritional analysis of Maltodextrin, a 100g serving of this substance contains 94.64g of carbohydrates, 89.0mg of sodium, and provides 375.0kcal of energy. This information is drawn from the US Department of Agriculture's FoodData Central system, where data for 'unflavored maltodextrin powder' was used in place of 'Maltodextrin'.

In relation to the macronutrients in Maltodextrin, the majority comes from carbohydrates. Carbohydrates are essential in providing energy for the body, with every gram of carbohydrate providing approximately 4 kilocalories of energy. Therefore, the 94.64g of carbohydrates in a 100g serving of Maltodextrin can provide approximately 378.56kcal of energy, almost all of the total calorie content of Maltodextrin.

The sodium content in Maltodextrin, though not as much as carbohydrates, is also noteworthy. Sodium plays a crucial role in maintaining fluid balance in the body and supports nerve and muscle function. A 100g serving of Maltodextrin provides 89.0mg of sodium, which is about 4% of the recommended daily intake for an average adult.

What's unique about Maltodextrin among other carbohydrate sources is its high glycemic index. This means it quickly raises blood sugar levels after consumption, which can be beneficial for athletes who need quick energy during intense workout sessions. However, this property might not be suitable for everyone, especially those with certain health conditions that require careful monitoring of blood sugar levels.

'Maltodextrin' was not found in FoodData Central, so nutritional data for 'UNFLAVORED MALTODEXTRIN POWDER' was used instead under Cast Iron Keto's editorial and research standards.

Health Implications of Maltodextrin on a Keto Diet

Taking into account the high carbohydrate content of Maltodextrin, maintaining a state of ketosis while consuming this food can be challenging. Ketosis, the metabolic state where the body uses fat for energy instead of carbs, requires a low-carb intake. Given Maltodextrin's high carb content, even small amounts can disrupt this balance and hinder the body's ability to remain in ketosis.

Looking at the nutritional data, Maltodextrin provides some calories, registering at 375.0kcal per 100g, offering energy. However, it lacks substantial amounts of vitamins, minerals, and other healthy nutrients, limiting its overall nutritional benefit.

Keto-Compatible Alternatives for Maltodextrin

  1. Erythritol: This sugar alcohol is a popular sweetener in keto recipes due to its negligible carb content. It can be used in baking and cooking similar to sugar, making it a viable replacement for Maltodextrin.
  2. Stevia: A natural, zero-calorie sweetener derived from the leaves of the stevia plant. Stevia is much sweeter than sugar, so less is required in recipes, helping to keep the carbohydrate count low.
  3. Monk Fruit Sweetener: This is another natural, zero-calorie sweetener that's compatible with a keto diet. It can be used as a Maltodextrin substitute in a variety of recipes, from baked goods to beverages.

Concluding Thoughts on Maltodextrin and Keto

The key takeaway from our discussion is clear: Maltodextrin and the ketogenic diet aren't a compatible pair. The high carbohydrate content of Maltodextrin, which is nearly 95% of its total weight, presents a significant hurdle for anyone aiming to keep their daily carb intake low. This aspect, coupled with a high glycemic index, makes Maltodextrin a substance to be cautious about when following a ketogenic lifestyle.

While Maltodextrin can provide some calories, it lacks substantial amounts of other essential nutrients, limiting its overall nutritional contribution. And for those keeping an eye on their sodium intake, the sodium content in Maltodextrin may be a concern.

Finding suitable alternatives that align better with your dietary goals is key. Natural sweeteners like Erythritol, Stevia, and Monk Fruit Sweetener offer the sweetness without the carb load, making them a more fitting choice for those on a keto diet.

Cast Iron Keto's Editorial and Research Standards

Certain rare or exotic food items may not have nutritional profiles in the FoodData Central database. If an exact match is not found in the FoodData Central database, then, the Cast Iron Keto team utilizes a three-prong approach to provide readers with the closest relevant nutritional data, where possible.

First, in the event that nutritional profiles for a rare or exotic food item is not available in the FoodData Central database, we investigate alternative names for that particular food item and use that data, when possible. Second, in cases where no alternate names exist, Cast Iron Keto will use nutritional data for a close relative or similar food item. Finally, if no close relatives or similar items exist, we refrain from publishing nutrient data tables.

When making dietary or health decisions based on FoodData Central's data, we suggest readers consult with a nutritionist or other health experts, particularly if the food in question has a significant role in your diet or if you are using the food item to treat any health disorder(s).

Furthermore, it is important to note that even if a close relative or similar item is used to approximate the nutritional data, different food items can have varying levels of nutrients due to factors such as soil quality, farming practices, and regional differences.
