Is Maltitol Keto-Friendly?

Despite its prevalence in low-carb and sugar-free products, Maltitol isn't keto-friendly due to its high carbohydrate content.

This article dives into an in-depth exploration of Maltitol's nutritional profile, highlighting why its carb content poses a serious challenge for those adhering to a ketogenic diet.


  • No, Maltitol isn't keto-friendly due to its high carbohydrate content.
  • Consuming Maltitol can disrupt the delicate balance of carbs required for ketosis.
  • High sodium levels in Maltitol can also have potential health implications.

Is Maltitol Keto-Friendly?

Maltitol, a commonly used sugar alcohol in many low-carb and sugar-free foods, is not considered keto-friendly. The key reason for this categorization lies in its carbohydrate content.

For every 100 grams of Maltitol, there's a significant amount of 90.14 grams of carbohydrates. This high carb content is rather surprising for those under the assumption that sugar alcohols are virtually carb-free. It's important to recognize that not all sugar alcohols are created equal, and Maltitol's high carb content can impact ketosis.

Delving into typical servings, there's 1.8 grams of net carbs in a 2-gram serving of Maltitol. It might seem insignificant, but considering the typical consumption of sugar alcohols in keto-friendly foods, these carbs can quickly add up, making it a sneaky source of carbs that could disrupt a strict low-carb regimen.

Can You Have Maltitol On a Strict Keto Diet?

Given its high carbohydrate content, Maltitol does not fit well with a strict ketogenic diet. A strict version of this diet typically involves consuming less than 20 grams of carbs per day. Considering that a small 2-gram serving of Maltitol has 1.8 grams of net carbs, it is clear that including this sweetener in your diet could quickly lead to exceeding your daily carb limit.

Even for individuals who follow a more relaxed version of the keto or low-carb diet, where the daily net carb intake is limited to 30-50 grams, including Maltitol can still pose a challenge. Its high carb content could easily lead to an unintentional increase in daily net carbs, disrupting the balance of macronutrients needed to maintain a state of ketosis.

Carbs In Maltitol

Taking a closer look at the carbohydrate content in Maltitol, it's evident that this sweetener is quite high in carbs. In every 100 grams of Maltitol, there are 90.14 grams of carbohydrates. This high carbohydrate count is a significant consideration for those following a keto or low-carb diet.

When we break it down to a typical serving size of 2 grams, Maltitol contains 1.8 grams of net carbs. Net carbs are calculated by subtracting fiber and sugar alcohols from the total carbohydrates, and they're the carbs that your body actually digests and uses for energy. In the context of a low-carb or keto diet, where every gram of carbohydrate counts, this can make a substantial difference.

Now, you might be wondering about Maltitol's glycemic index. The glycemic index is a measure of how much a food raises blood sugar levels compared to pure glucose. Foods with a low glycemic index are digested and absorbed more slowly, leading to a slower and smaller rise in blood sugar levels. Maltitol has a relatively low glycemic index compared to other sugars, which makes it a popular choice in low-carb and sugar-free foods.

Maltitol Nutrition Facts

Maltitol, like many other sugar substitutes, provides a sweetness without the same carbohydrate load, making it a popular choice for those watching their sugar intake. In a 100g portion of Maltitol, you can find 90.14g of carbohydrates. Despite being a sugar substitute, it's still important to watch the carbohydrate content if you are monitoring your intake.

Maltitol also contains a small amount of protein – 0.66g per 100g. Although not a significant source, every bit of protein counts toward meeting your daily requirement.

An interesting fact about Maltitol is its sodium content – 150.0mg per 100g. Our bodies need sodium to perform various functions, like muscle contractions and maintaining the proper balance of water and minerals. But, it's necessary to keep in mind not to go overboard as high intake can lead to health concerns.

Potassium is another mineral found in Maltitol, with 4.0mg per 100g. Though the quantity is not substantial, potassium plays a vital role in maintaining fluid balance, nerve signals and muscle contractions in the body.

Iron is present in trace amounts, with only 0.02mg per 100g. Despite being in small quantity, iron is a vital nutrient that helps in transferring oxygen in your blood, and its deficiency can lead to anemia.

Similarly, Maltitol has a tiny amount of Selenium – 0.1ug per 100g. This mineral is essential for proper thyroid function and protecting our body from damage caused by oxidative stress.

Considering its calorie content, Maltitol contains 349.0kcal per 100g. These calories come from its carbohydrates and a small quantity of protein.

Lastly, water makes up a small portion of Maltitol as well, being 8.79g per 100g. This might seem inconsequential, but every bit contributes to your daily hydration needs.

Health Implications of Maltitol on a Keto Diet

Including Maltitol in a ketogenic diet can present several challenges due to its high carbohydrate content. Consuming Maltitol in any significant amount can make it difficult to stay within the carb limits necessary for maintaining ketosis, which is a core aspect of the ketogenic diet.

Looking at the nutritional data of Maltitol, it does contain some minerals, albeit in low quantities. For instance, per 100 grams, it offers 150.0mg of Sodium, 4.0mg of Potassium, 0.02mg of Iron, and 0.1ug of Selenium. These minerals can contribute to various bodily functions such as maintaining fluid balance (Sodium), aiding nerve and muscle cell functioning (Potassium), supporting oxygen transport in the body (Iron), and contributing to DNA synthesis and protection from oxidative damage (Selenium).

However, it's worth noting that Maltitol is high in Sodium, with 150.0mg per 100g. While Sodium is necessary for the body, excessive amounts can lead to negative health implications, like high blood pressure and heart disease.

Keto-Compatible Alternatives for Maltitol

  1. Erythritol: Erythritol is a popular keto-friendly sweetener that boasts a carb content of practically zero. This sugar alcohol is typically well-tolerated and doesn't affect blood sugar levels, making it a perfect substitute for Maltitol in keto recipes. For instance, it can be used in place of Maltitol in baked goods or beverages for a sweet taste without the carbs.
  2. Stevia: A natural sweetener derived from the leaves of the Stevia rebaudiana plant, Stevia is another great Maltitol alternative. It’s much sweeter than sugar, so a little goes a long way. Plus, it contains no carbs or calories, making it a safe choice for keto dieters. It works well in countless recipes, from smoothies to keto-friendly desserts.
  3. Monk Fruit Sweetener: This sweetener is derived from monk fruit and, like Stevia, is significantly sweeter than sugar. It has zero carbs and zero calories, which makes it another excellent alternative to Maltitol for those following a ketogenic diet. It can be used in a variety of dishes, including keto pancakes, muffins, and other baked goods.

Concluding Thoughts on Maltitol and Keto

To sum up, Maltitol, while a common ingredient in many low-carb and sugar-free foods, is not considered keto-friendly due to its high carbohydrate content. Its 90.14 grams of carbs per 100 grams, and 1.8 grams of net carbs per 2-gram serving can quickly tip the scales, disrupting the carefully balanced macronutrient intake required for a successful keto diet.

Despite its low glycemic index and some mineral content, the high carb content of Maltitol poses a considerable challenge for those trying to maintain ketosis. Moreover, its high sodium content is something that needs to be taken into account when considering overall health.

There are several keto-friendly alternatives to Maltitol, such as Erythritol, Stevia, and Monk Fruit Sweetener, that provide the sweetness without the carbs. These can be a great way to enjoy the sweet flavor in your keto recipes without disrupting your diet.
