Sugar alcohols are a great alternative to regular sugar for those on the keto diet. They are sweeteners that taste and feel similar to sugar but have fewer calories and a less significant impact on blood sugar levels. This is because they are not easily digestible, and so they are a good option for those on keto who want to avoid insulin resistance and remain in ketosis. Common sugar alcohols include erythritol, xylitol, and isomalt. However, it's important to note that sugar alcohols can cause digestive issues such as bloating, nausea, and diarrhea, especially in larger amounts.
What You'll Learn
Sugar alcohols are harder to absorb and digest
The human body struggles to fully break down and absorb sugar alcohols. They are mostly digested in the small intestine, but remnants that are not digested are passed to the large intestine and broken down by bacteria. This process can lead to gastrointestinal issues such as bloating, nausea, and diarrhea, especially if consumed in large quantities.
Sugar alcohols are often used as sweeteners in sugar-free products, providing a sweet taste without the calories and metabolic effects of sugar. They are also used in medications, laxatives, and toothpaste. Common sugar alcohols include erythritol, xylitol, maltitol, and sorbitol.
While sugar alcohols are harder to digest, they are not undigestible. Some types are partially digested and can still cause a rise in blood sugar levels, especially if consumed in excess.

They are lower in calories
Sugar alcohols are lower in calories than regular sugar. This is because they are less digestible, so the body absorbs fewer calories and carbohydrates. Sugar alcohols are commonly used as sugar substitutes and are added to foods marketed as "sugar-free" or "no sugar added". They are also frequently used to sweeten sugar-free or diet products like gum, yogurts, ice cream, and salad dressings.
The low-calorie content of sugar alcohols is due to their chemical structure. They have a similar structure to glucose but with an additional hydroxyl group (-OH, or alcohol group) attached. This makes them harder for the body to absorb and digest.
Some common sugar alcohols and their corresponding calories are:
- Erythritol: 70% of the sweetness of sugar but 5% of the calories
- Isomalt: 50% fewer calories than sugar
- Maltitol: 90% as sweet as sugar with almost half the calories
- Sorbitol: 60% as sweet as sugar with about 60% of the calories
- Xylitol: As sweet as regular sugar but with 40% fewer calories
Sugar alcohols are a great option for people following a keto diet as they provide sweetness without the calories and metabolic effects of regular sugar. They help to keep the body in a state of ketosis, which is key for reaping the benefits of the keto diet.

Sugar alcohols are commonly found in sugar-free products
Sugar alcohols are sweeteners that have tastes and textures similar to those of sugar, but with fewer calories and a less significant effect on blood sugar levels. They are often used as a low-calorie way to sweeten food products. Common sugar alcohols include erythritol, isomalt, maltitol, sorbitol, and xylitol.
Sugar alcohols have a different chemical structure to regular sugars, which makes them harder to absorb and digest. This means that they yield fewer calories and carbohydrates. Sugar alcohols are only partially digested and broken down in the small intestine, with remnants that are not digested being broken down by bacteria in the large intestine and passed through stool.
The different types of sugar alcohols include xylitol, maltitol, sorbitol, and erythritol. Mannitol and glycerol are also sugar alcohols. These sweeteners vary slightly in structure but maintain the core structure of a sugar with an additional alcohol group attached.
Sugar alcohols are commonly found in keto-friendly products as they have a much lower impact on blood sugar spikes due to them not being easily digestible. This makes them an ideal substitute for baking or cooking, as well as for selecting keto-friendly products.

They have a different molecular structure to regular sugars
Sugar alcohols are a mixture of alcohol and sugar molecules. They are similar in structure to glucose but with an alcohol group attached. This gives them a different molecular structure to regular sugars, making them harder to absorb and digest.
Sugar alcohols are often referred to as polyols and are commonly used as sugar substitutes. They are frequently found in products labelled as \"sugar-free\" or \"no sugar added\". They are also naturally present in certain fruits and vegetables.
The most common sugar alcohols include xylitol, maltitol, sorbitol, and erythritol. These sweeteners vary slightly in structure but maintain the core feature of being a sugar with an additional alcohol group attached.
The differences in structure between sugar alcohols and regular sugars account for differences in digestion and their impact on blood sugar levels. Sugar alcohols are only partially digested, leading to fewer calories and carbohydrates. This makes them a popular choice for those following a keto diet, as they have a much lower impact on blood sugar spikes.
However, it is important to note that not all sugar alcohols are the same. Erythritol, for example, has a glycemic index of zero and is well-tolerated by most individuals. On the other hand, maltitol and sorbitol should be avoided on a ketogenic diet as they can cause an increase in blood glucose levels and severe gastrointestinal issues.

Sugar alcohols can cause digestive issues
The side effects of consuming sugar alcohols are dose-dependent, meaning the more you consume, the more likely and severe the symptoms will be. Individuals with irritable bowel syndrome (IBS) or other inflammatory bowel diseases may be more susceptible to these side effects and may experience negative reactions even with small amounts of sugar alcohols.
To avoid digestive issues, it is recommended to consume sugar alcohols in moderation and be mindful of your body's tolerance. Some sugar alcohols, such as erythritol, are better tolerated and cause fewer gastrointestinal issues. However, others like maltitol and sorbitol are known to cause more severe GI issues and should be avoided or limited.
Additionally, sugar alcohols can have a "laxative effect" due to their ability to draw water into the intestine, which can lead to diarrhea. This effect is particularly associated with maltitol, which is often found in sugar-free products and carries a warning label for its potent laxative-like effect.

Frequently asked questions
Sugar alcohols are sweeteners that taste and feel similar to sugar but have fewer calories and a less significant effect on blood sugar levels. They are commonly used as sugar substitutes and are often added to foods marketed as "sugar-free" or "no sugar added".
Yes and no. Sugar alcohols have a lower impact on blood sugar spikes due to their different molecular structure, which makes them harder to digest. This makes them a good substitute for regular sugar in keto-friendly products and recipes. However, not all sugar alcohols are equal; some have higher glycemic indexes and can affect blood sugar levels more than others.
Sugar alcohols are less calorie-dense than sugar, making them a great option for low-carb baking and cooking. They are also less sweet, which can help reduce sugar cravings. Additionally, they do not contribute to tooth decay as they are not fermented by bacteria in the mouth.
Sugar alcohols can cause digestive issues such as bloating, diarrhea, and stomach aches, especially if consumed in excess or by those with digestive sensitivities. They may also inhibit gut bacteria and reduce the health benefits of a diverse gut flora. Overconsumption of sweet treats made with sugar alcohols is also a risk due to their lower calorie and carb content.
