Sorbitol's Impact On Ketosis: Friend Or Foe?

Sorbitol is a sugar alcohol, a type of sweetener with a similar taste and texture to sugar, but with fewer calories and a less significant effect on blood sugar levels. It is derived from glucose and is 60% as sweet as sugar with about 60% of the calories.

Sugar alcohols are often used as a substitute for sugar in keto-friendly products, as they have a negligible effect on blood sugar levels. However, sorbitol is not considered keto-friendly by some sources due to its relatively high net carb content. It contains 3.25g of net carbs per 10g serving, so it is important to be mindful of serving sizes to avoid exceeding the recommended daily net carb limit of 20-30g.

While sorbitol is allowed on keto in moderation, it may be better to use non-glycemic and non-caloric sweeteners such as stevia, monk fruit, and erythritol, which have a more favourable impact on blood glucose levels and are better tolerated by the body.

Sorbitol is a sugar alcohol with a low-glycemic index of 4

Sugar alcohols are derived from sugar and are chemically very similar to it. The term "alcohol" in this context does not refer to alcoholic drinks but to the presence of a hydroxy group on their molecule. Sugar alcohols are digested differently from glucose, and because of this, they yield fewer calories and carbohydrates.

Sorbitol contains 3.25g of net carbs per 10g serving. It is important to be mindful of the serving size because it has a fair amount of carbs. To stay in ketosis, it is recommended to limit daily net carb intake to 20-30g.

While sorbitol is allowed on keto, it should be consumed in moderation. It still contains carbs and may prevent you from reaching ketosis if you consume too much. As an alternative, you may use non-glycemic and non-caloric sweeteners such as stevia, monk fruit, and erythritol.

Erythritol, for example, is the most well-tolerated sugar alcohol and causes minimal GI issues. It is commonly found in keto baked goods and drinks and does not impact blood glucose levels. Xylitol is another keto-friendly sugar alcohol that is commonly found in chewing gum and may improve oral health and prevent tooth decay.

Maltitol and sorbitol are two sugar alcohols that should be avoided on a ketogenic diet. They are partially digested, cause an increase in blood glucose levels, and can cause severe GI issues.

It has 3.25g of net carbs per 10g serving

Sorbitol is a sugar alcohol with a low-glycemic index of 4. It has 3.25g of net carbs per 10g serving. This means that you need to be mindful of its serving size because it has a fair amount of carbs.

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. As a result, they can be a satisfying option for individuals looking to reduce their sugar intake, such as those following a keto diet.

However, it's important to note that sorbitol is not a keto-friendly sugar alcohol. While it can be consumed in moderation on a keto diet, it is not a good replacement for sugar. This is because it has a high net carb content and is only 60% as sweet as sugar.

To get the same sweetness as 100g of sugar, you would need 160g of sorbitol, which contains 100g of net carbs. This is a significant amount, especially considering that the recommended daily net carb limit for keto is 20-30g.

Therefore, if you are following a keto diet, it is best to choose alternative sweeteners such as erythritol, stevia, or monk fruit, which have minimal impact on blood glucose levels and are better tolerated by the body.

Erythritol, stevia, and monk fruit are alternative sweeteners for keto

Erythritol is a sugar alcohol derived from corn via fermentation. It has 70% of the sweetness of sugar and is less likely to cause gastrointestinal distress than other sugar alcohols. Erythritol has a slight cooling sensation on the tongue, which may be unpleasant in large doses. It is considered safe by the FDA and does not cause blood sugar spikes or promote tooth decay.

Stevia is a natural sweetener that comes from the stevia plant, native to South America. It is generally recognised as safe and is 100 to 300 times sweeter than sugar. Stevia can have a bitter aftertaste and may lower blood sugar and blood pressure. It works well in coffee and tea but may not be suitable for baked goods due to its high sweetness.

Monk fruit is a sweetener derived from a plant native to China. It is recognised as safe by the FDA and is 100 to 250 times sweeter than sugar. Monk fruit contains no calories and has a negligible amount of carbohydrates. It can be used in salad dressings, drinks, and baked goods, but it may affect the texture of baked goods.

These alternative sweeteners can be used as substitutes for sugar in the keto diet, which requires a reduction in carbohydrate intake to induce ketosis.

Sorbitol is partially digested in the small intestine

Sorbitol is a sugar alcohol that is only partially digested in the small intestine. The unabsorbed sorbitol then moves into the large intestine, where it is fermented by bacteria. This means that fewer calories are absorbed from sorbitol than from table sugar. As a result, sorbitol has very little effect on blood sugar levels when eaten and is often added to foods marketed to people with diabetes.

Sorbitol is commercially manufactured from corn syrup and is commonly found in packaged foods, beverages, and medications. It is used to preserve moisture, add sweetness, and provide texture to products. It is also used as a laxative to combat constipation, as it draws water into the colon from surrounding tissues to promote bowel movements.

While sorbitol is considered safe to consume by many global health authorities, including the FDA, consuming large amounts can cause digestive side effects such as bloating and diarrhea in some people, especially if they are not used to regularly consuming sorbitol. This is due to the osmotic load caused by sorbitol in the small intestine, which reduces the digestibility of other nutrients. Therefore, it is important to limit sorbitol consumption to moderate amounts to avoid exceeding the daily net carb limit for keto and to prevent gastrointestinal distress.

Sorbitol is not keto-friendly due to its high net carbs

Sorbitol is a sugar alcohol with a low glycemic index of 4. It is often used as a sugar substitute in products labelled as "sugar-free". While it has fewer calories and carbohydrates than table sugar, it still contains a moderate amount of net carbs—3.25g per 10g serving.

On a keto diet, it is crucial to keep net carb intake between 20-30g per day to maintain ketosis, a state where the body burns fat for energy instead of sugar. As sorbitol counts towards this daily net carb limit, consuming too much can prevent you from reaching and maintaining ketosis.

To illustrate, if you wanted the same level of sweetness as 100g of sugar, you would need 160g of sorbitol, which equates to 100g of net carbs. This amount of net carbs is significantly higher than the recommended daily limit for keto, making sorbitol a poor choice as a sugar substitute while on this diet.

Instead, it is recommended to use non-glycemic and non-caloric sweeteners such as stevia, monk fruit, and erythritol, which have minimal impact on blood glucose levels and are better tolerated by the body.
