Sugar alcohols are a type of sweetener commonly used in low-carb, keto, sugar-free, or diet-friendly foods. They are neither a sugar nor an alcoholic beverage. They are organic compounds that are naturally found in fruits and vegetables. Sugar alcohols are hard for our bodies to digest and are used as low-calorific sweeteners. They have a similar chemical structure as sugar, and they activate the sweet taste receptors on our tongue. To calculate sugar alcohol on keto, you can use the formula: Net Carbs = Total Carbs – Dietary Fiber – Sugar Alcohols.

Sugar alcohols are a type of sweetener commonly used in low-carb, keto, sugar-free, or diet-friendly foods
Sugar alcohols are used as sweeteners because they are low-calorie and low-energy. They are also tooth-friendly and do not contribute to tooth decay. They are used in sugar-free and low-carb foods because they are hard for the body to digest and do not raise blood sugar levels as much as regular sugar.
The most common sugar alcohols include mannitol, erythritol, sorbitol, isomalt, lactitol, xylitol, and maltitol. Erythritol is often considered the best sugar alcohol for keto as it has almost zero calories and is about three-quarters as sweet as regular sugar, making it great for baking. It also has the smallest laxative effect compared to other sugar alcohols and can even help prevent tooth decay.
However, it is important to note that not all sugar alcohols are equal. Some can cause digestive issues, such as bloating, flatulence, and diarrhea, especially if consumed in large amounts. Some sugar alcohols are even toxic to dogs. Additionally, some sugar alcohols can contain carbohydrates and may impact blood sugar levels, which is important to consider when following a keto diet.
When calculating net carbs on a keto diet, the general formula is to subtract the dietary fiber and sugar alcohols from the total carbohydrates. However, it is important to read labels carefully as not all sugar alcohols are treated equally, and some may need to be counted partially or in full towards net carbs.

Sugar alcohols are sugar molecules with an alcohol group attached
Sugar alcohols, also known as polyols, are a type of carbohydrate derived from fruits and vegetables. They are neither sugar nor alcohol, despite their name. Sugar alcohols are a class of polyols, which are hydrogenated carbohydrates used as sugar replacers. They are commonly used as sweeteners and bulking agents, providing a sweetness similar to sugar without the same metabolic effects.
The chemical structure of sugar alcohols is similar to both sugar and alcohol, hence the name. However, they do not contain ethanol, which is found in alcoholic beverages. Sugar alcohols have a unique structure, with an alcohol group attached to a sugar molecule. This gives them different properties from both sugar and alcohol.
Sugar alcohols are often used in "sugar-free" or "no sugar added" products, including hard candies, cookies, chewing gums, soft drinks, and throat lozenges. They are also found in toothpaste and mouthwash. Sugar alcohols are popular among individuals with diabetes, as they have a reduced effect on blood sugar levels. They are also used by those looking to lose weight, as they provide fewer calories than regular sugar.
Some common sugar alcohols include mannitol, sorbitol, xylitol, lactitol, isomalt, maltitol, and hydrogenated starch hydrolysates (HSH). These sugar alcohols are not easily digested or absorbed by the body, which can lead to gastrointestinal issues if consumed in excess. It is recommended to introduce sugar alcohols gradually into your diet and monitor how your body responds.
When calculating net carbs on a keto diet, sugar alcohols can be treated differently. While they are a form of carbohydrate, they are not fully absorbed by the body. Some experts suggest subtracting the total amount of sugar alcohol from the total carbs to get the net carbs. However, others recommend a more conservative approach, counting half of the sugar alcohol amount as carbohydrates. This is because some sugar alcohols can still affect blood sugar levels, and individual tolerance varies.

Sugar alcohols are metabolised differently, with some not being fully absorbed by the gut
Sugar alcohols are a type of sweetener commonly used in low-carb, keto, sugar-free, or diet-friendly foods. They are neither a sugar nor an alcoholic beverage. Chemically, they are sugar molecules with an alcohol group attached. Sugar alcohols are metabolised differently, with some not being fully absorbed by the gut.
Sugar alcohols are hard for the body to digest. This is why consuming them in large amounts may cause digestive problems such as cramping, gas, and diarrhoea. They are also known to have a laxative effect. This is because they are not completely broken down and absorbed by the body. Instead, they pass through the body unchanged.
Sugar alcohols are often used as sweeteners in "sugar-free" or "no sugar added" products, such as Atkins, Quest Nutrition, and other low-carb ketogenic-friendly products. Some examples of sugar alcohols include mannitol, erythritol, sorbitol, isomalt, lactitol, xylitol, and maltitol. Erythritol is the most common keto-approved sugar alcohol used in low-carb recipes.
The impact of sugar alcohols on the body depends on the type. For example, erythritol does not raise blood sugar or insulin levels and is, therefore, a good option for those on a keto diet. On the other hand, sugar alcohols such as sorbitol, xylitol, and maltitol do raise blood sugar and, consequently, insulin levels. These are commonly used in products labelled as "low carb", "sugar-free", or "net carb".
To calculate net carbs when consuming sugar alcohols, use the following formula: Net Carbs = Total Carbs – Fiber – Sugar Alcohols. However, it is important to note that not all sugar alcohols are truly carb-free. Some can impact blood sugar levels, so it is recommended to count half of the sugar alcohol amount as carbohydrates. Therefore, the formula for calculating net carbohydrates when playing it safe is: Net Carbs = Total Carbs – Fiber – 1/2 Sugar Alcohols.
It is worth mentioning that sugar alcohols can have some negative side effects, such as bloating, flatulence, and diarrhoea, especially when consumed in large quantities. Additionally, some sugar alcohols are toxic to dogs, so it is important to keep products containing them out of their reach.

Sugar alcohols can cause digestive issues if consumed in large quantities
Sugar alcohols are carbohydrates that are neither sugars nor alcoholic beverages. They are commonly used as sweeteners and bulking agents in food products. While they are generally well-tolerated, consuming large amounts of certain sugar alcohols can lead to digestive issues.
Sugar alcohols are not completely absorbed by the gut, and their consumption in large quantities can lead to a laxative effect and gastrointestinal problems. These issues include bloating, gas, and diarrhea. Most people can usually tolerate 20 to 30 grams of sugar alcohols per day without experiencing any significant digestive problems. However, this amount can vary depending on individual factors and the specific type of sugar alcohol consumed.
The most common sugar alcohols that can cause digestive issues are mannitol, sorbitol, and maltitol. Mannitol, often found in sugar-free gums and candies, lingers in the intestines and can cause bloating and diarrhea. Sorbitol, another common ingredient in sugar-free products, has a similar effect and may also contribute to a laxative effect. Maltitol, used in sugar-free candies, chocolate, and ice cream, can also lead to digestive issues if consumed in large quantities.
It is important to note that not all sugar alcohols have the same effects on digestion. For example, erythritol, a popular sugar alcohol, is well-tolerated by the body and does not cause the same digestive side effects as other sugar alcohols. This is because most of it is absorbed by the small intestine and does not reach the large intestine in significant amounts.
To avoid digestive issues, it is recommended to consume sugar alcohols in moderation and be mindful of the specific types and amounts present in food products. Checking nutrition labels and consulting with a registered dietitian can help determine the appropriate amount of sugar alcohols in one's diet.

Erythritol is the best sugar alcohol for keto
Erythritol is a sugar alcohol commonly used as a sugar substitute. It is often made by fermenting the glucose found in cornstarch and has 70% of the sweetness of sugar but only 5% of the calories. It is also the most keto-friendly sugar alcohol as it has a glycemic index of 0 and works well in both cooking and baking.
On the ketogenic diet, it is important to reduce your sugar intake so that your body can enter ketosis, a state in which it burns fat for energy instead of sugar. Sugar alcohols are popular on keto as they are sweeteners that taste and feel similar to sugar but have fewer calories and a less significant effect on blood sugar levels.
When calculating net carbs on keto, you would subtract the fibre and sugar alcohols from the total carbohydrates. However, it is important to note that not all sugar alcohols are the same and some may impact your blood sugar levels. Erythritol is well-tolerated and has a minimal effect on blood sugar, making it a good choice for keto.
Other sugar alcohols like xylitol, sorbitol, and isomalt are also suitable for keto but may cause gastrointestinal side effects for some people. It is recommended to scale back your intake of these if you experience any negative side effects. Maltitol, in particular, has a higher glycemic index and is likely to have a more significant effect on blood sugar levels, so it is best to limit your intake of this sugar alcohol on keto.
In summary, erythritol is the best sugar alcohol for keto as it has a low glycemic index, is well-tolerated, and has minimal impact on blood sugar levels. It is a popular choice for keto baking and cooking and can help satisfy your sweet tooth while sticking to the keto diet.

Frequently asked questions
To calculate net carbs on keto, take a food's total carbohydrates and subtract dietary fiber and sugar alcohols. The formula is: grams of total carbs – fiber – sugar alcohols = net carbs.
Sugar alcohols are a type of sweetener commonly used in low-carb, keto, sugar-free, or diet-friendly foods. They are also known as polyols and occur naturally in foods like berries and fruits. Chemically speaking, sugar alcohols are sugar molecules with an alcohol group attached to them.
Sugar alcohols can be partially or entirely indigestible, which is why they are used in sugar-free and lower-carb foods. They don't raise your blood glucose levels as much as regular sugar and don't stimulate insulin secretion. However, some sugar alcohols can still impact your blood sugar, so it's important to factor them into your keto carb count if you eat a large amount.
