Sugar Alcohols: Are They Compatible with the Ketogenic Diet?

If you are following or considering a ketogenic diet or modified Atkins diet (MAD) for the management of intractable epilepsy, you may have heard talk about sugar alcohols and whether they are compatible with the diet. In today’s blog post, ketogenic dietitian Stacey Bessone will tell us more about sugar alcohols and what role they play with the ketogenic diets.


Sugar alcohols are a specific type of carbohydrate called “polyols”. Sugar alcohols are naturally occurring in fruits and vegetables and often added to foods as a reduced-calorie alternative to sugar. Some common sugar alcohols you may see in food ingredient lists include:

  • Malitol
  • Sorbitol
  • Isomalt
  • Xylitol
  • Erythritol

It’s important to be aware that some sugar alcohols may cause some people to experience bloating, gas and diarrhea, even when consumed in small amounts.

Sugar Alcohols & Glycemic Index

Interestingly, most sugar alcohols are incompletely absorbed in the small intestine, so they do not raise blood sugar the same way as sucrose (table sugar). However, since they are partially absorbed, they may affect blood glucose levels to some degree.   This can be observed by looking at the glycemic indexes of sugar alcohols compared to sugar. Glycemic index is a measure of the increase in blood glucose when a food is digested and absorbed. It is based on a numeric scale from zero to 100, where the glycemic index of glucose (a type of sugar you get from foods and the form that your body uses for energy) is 100. The glycemic index of sucrose (table sugar) is around 65, whereas the glycemic indexes of the main sugar alcohols are between 0 and 45. Therefore, sugar alcohols may raise your blood glucose, although not as much as sugars like sucrose and glucose.

One specific type of sugar alcohol, Erythritol, is metabolized differently than other sugar alcohols. Erythritol is fully absorbed in the small intestine and excreted in the urine unchanged, so it does not affect blood glucose levels like other sugar alcohols. As you can see in the chart above, the glycemic index of erythritol is zero.

Calories in Sugar Alcohols

Sugar alcohols provide fewer calories per gram compared to regular carbohydrates. Sugar alcohols are therefore often used as a reduced-calorie alternative to sugar.

Sugar Alcohols, Erythritol, and the Ketogenic Diet

So, are sugar alcohols allowed on the ketogenic diet and modified Atkins diet (MAD)?  Technically, most sugar alcohols should be counted as regular carbohydrates and kept to a minimum on the ketogenic and modified Atkins diets (MAD). Although they may affect blood glucose differently in different people, most sugar alcohols have the potential of raising blood sugar. The exception to this rule is erythritol, since it is metabolized differently and does not affect blood glucose.  I generally tell my ketogenic diet and modified Atkins diet (MAD) patients that when reading a food label for carbohydrate content, erythritol is the only sugar alcohol that can be deducted from total carbohydrate content. I also tell my patients that sugar alcohol can only be deducted from the total carbohydrate amount if erythritol is the only sugar alcohol used in a product. When other sugar alcohols are used in addition to erythritol, the sugar alcohol content cannot be deducted, so I tell my patients to read the food label’s ingredient list carefully.

Speak to Your Healthcare Provider

Each dietitian has his/her own protocols, so while I allow my keto patients to deduct erythritol but no other sugar alcohols from total carbohydrate content, your provider may have different recommendations. As always, it’s important to speak to your dietitian about which foods and ingredients are allowed for your unique diet.

Keto-friendly Thanksgiving & Holiday Recipes

Thanksgiving and holiday meals tend to be food-focused. This can be stressful when you or a loved one is on the ketogenic diet for the dietary management of intractable epilepsy. However, with KetoCal® and a little extra planning (okay, maybe a lot), you can put together a delicious and keto-friendly holiday feast. Reach out to your ketogenic dietitian far in advance for help putting together a meal that meets your calorie and ratio requirements. Here are some delicious and keto-friendly recipe ideas to get you started.

For Hanukkah recipe Ideas, see our previous post here.

Main Course:

Every family has their own traditions when it comes to main courses for holiday dinners.  Whether ham, beef, poultry or fish is served, be mindful of rubs or glazes that may contain carbohydrates.  You can use  butter or a high-fat sauce to even out the ketogenic ratio. For example, you could create a creamy gravy using heavy cream or Liquigen® (emulsified MCT oil), mixed with chicken or beef bouillon granules.

Most families serve turkey on Thanksgiving. If possible, opt for dark meat since it has a higher fat content.  If you’re up for something a little different, consider these turkey dishes that are already in a 3:1 ketogenic ratio:

Side Dishes:

For many, side dishes are the best part of the meal! Here are some tasty and keto-friendly options:

Ella’s Journey with Dravet Syndrome and the Ketogenic Diet

Ella on the way to an appointment with her ketogenic dietitian

Ella is 9 years old. She has an orange belt in tae kwon do and is very excited to be going to a new school for 3rd grade. The best way I can describe my daughter is that I wish everyone had the same approach to life and towards others as she does. She is optimistic, kind, and compassionate to anyone she meets. One would not expect such a positive or loving disposition from a child who has been through so much in such a short time.

Dravet Syndrome

We assumed Ella was healthy when she was born a hefty 8lbs 15ozs. She was very curious and social as an infant. Ella was around 10 months old when we realized something was very wrong. She had her first seizure during a nap. It lasted over 2 hours and required her to be intubated for 2 days. We were told it was due to high fever, and were convinced it was the last one she would ever have until she started having them several times a week. She had been intubated 4 times before we knew what we were dealing with. Ella was diagnosed with a genetic condition called Dravet Syndrome at 3 years old. It is a rare and catastrophic form of epilepsy that brings with it a host of medical complications ranging from global delays to chronic infection. It never goes away and it does not always improve over time.

The Ketogenic Diet

Ella had been prescribed several anti-epileptics with little to no noticeable seizure control. She was often in a drug-induced fog or extremely irritable. Her neurologist recommended we put her on the ketogenic diet.

The decision to place Ella on such a restrictive diet was not one that was taken lightly. After researching it, we at first felt overwhelmed and reluctant to try it because of the potential adverse effects involved (the most common problems are digestive issues, although these can usually be managed under the care of a keto dietitian). We also knew that managing the ketogenic diet would be a time commitment, and we struggled with the idea that Ella would not be able to eat food other children could eat. I remember wondering how I was going to keep up with it. I worked full time and had Ella and her younger sister. There were a lot of factors delaying us (my husband and I) from making the choice. However, we decided that we had more to gain by trying it. We knew that if it did not work, we could take Ella off of it and try something else. Fortunately, we met several families who had their children with Dravet Syndrome on the ketogenic diet who were experiencing fewer seizures. They shared their stories with us and it put us at ease.

Following a brief admission to the hospital in order to safely wean Ella onto the ketogenic diet, her dietitian sent us home with several recipes. Ella’s keto dietitian encouraged us to try KetoCal® products to help us find some meal alternatives. KetoCal offered several tasty options for kids such as ready-made shakes (plain or vanilla) and powder mixes that could be used in sweet or savory meals.

After 4 days of being on the keto diet, Ella used the bathroom on her own for the first time. Her speech and cognition improved dramatically, and more importantly she went 6 months without a seizure. It was the longest she had gone without one since 10 months old.

My daughter has been on the ketogenic diet for 5 and half years. Part of why keto has worked for Ella is that we make her a part of the process by empowering her as much as possible. We create new recipes often, based on her requests. This gives her a sense of control over what she eats. Seeing Ella smile after she tastes something new is a huge pay off.

Advice for Other Parents

If you have a child with Dravet Syndrome or intractable epilepsy, please consider the ketogenic diet as a low side-effect option for managing seizures. The diet may not be right for everyone, but it works wonders for so many with uncontrolled seizures. Please do not hesitate to speak with your neurologist about having a consultation with a keto dietitian, or even reaching out to members of the epilepsy and ketogenic diet community. There are many groups on Facebook where you can connect with other families who have tried the ketogenic diet, such as:
