Sugar Alternatives for Keto Dieters

 The keto diet is such a great way to get rid of those unwanted pounds and reduce inflammation but of course to achieve any kind of success you’ll have to adjust your eating plan and stop sugar.

For one thing, if you continue to eat sugar, your carb count will be so high that you won’t enter into ketosis.  And second, we can no longer avoid all the news about just how bad sugar is for inflammation. Read more in this Medical News today article about sugar and inflammation 

Bottom line, we can no longer eat desserts that are loaded with carbs and sugar.  So we use sugar alternatives and substitutes instead.

But which sweeteners are the best ones for Keto?

The answer is going to depend on what you want to do with the sweetener.  

There are plenty of sugar alternatives available that you can use to not only add to your favorite beverages, but to use in baked goods or in making regular meals that call for sugar.

These sugar alternatives come in styles that mimic granulated sugar, powdered and brown sugar and are low in carbs, so you get the sweet taste without risking your state of ketosis.

Say No to Sugar

There are two basic categories of sugar alternatives for keto: artificial sweeteners and natural sweeteners.

All of these sweeteners below are considered to be natural sweeteners and therefore compliant for keto dieters, who are wanting to follow a clean Keto program.  

Note:  Some people do what it known as ‘Dirty Keto‘, in other words if it fits in your macros then you can use it.   You can read more about the different types of Keto here.

1. Erythritol

The best keto sweetener for general overall use is erythritol. It’s a compound that’s known as sugar alcohol. You can find this type of sweetener naturally. Erythritol is what gives certain vegetables and fruits that sweet flavor.

When you use manufactured erythritol, it works by triggering the sweet taste buds located on the tip of your tongue. Your taste buds can’t tell the difference between the sweetener and regular sugar, so you get the same effect, but without the carbs.

  • Erythritol is about 70% as sweet as sugar so you may need to combine it with another sweetener when trying to duplicate the same sweetness as in a conventional recipe
  • It has no impact on blood sugar which is why the carbs are not usually counted in recipes
  • It does not have the laxative effect that most other sugar alcohols have because virtually none of it is absorbed by the body.
  • It tends to crystallize in some recipes especially if heated and then cooled, such as in a custard

Erythritol brands to buy:  (Look for 100% erythritol.  The ones I listed below are ones I use, there are many others I have not tried)

2. Xylitol

Xylitol is another naturally occurring sugar alcohol sweetener that is made from birch trees.  Xylitol is good for tooth enamel, which is why you find it in packaged sugar free chewing gums and mints.

Xylitol is as sweet as sugar and doesn’t crystallize like erythritol so it’s also good for keto baking.

But in spite of these good qualities which should make it a good sweetener for keto, I can’t get excited about it for these reasons:

  • It’s higher on the glycemic index than erythritol (although not a lot).
  • Xylitol is partially metabolized by the body and therefore can cause gastro and tummy issues in a small percentage of people who use it.  (I’m one of them!)
  • It is highly toxic to dogs and this disqualifies it from being in my house!

Which one to buy:  Organic Xylitol

3. Monk Fruit

Monk fruit (also known as lo han guo) is derived from a fruit that comes from Asia and is hundreds of times sweeter than sugar. Yet, it doesn’t contain any calories.

  • Because monk fruit is so much sweeter than sugar, you cannot really use it for baking because it doesn’t have the volume you need for a baked good.
  • This is why you will often find monk fruit combined with erythritol in the stores. 
  • Be sure to always check those ingredients because I have also seen it combined with things like dextrose.  It defeats the entire purpose of using a sugar substitute for keto!

Safe monk fruit brands to buy: (Remember to check ingredients!)

4. Stevia

Although stevia is also a naturally occurring sweetener and I used it a lot in my early days of keto and low carb, I use it less and less now.

  • Like monkfruit, it is hundreds of times sweeter than sugar and so it’s a challenge to use it in baking.
  • I find it is best to use in liquid form when you need a couple quick drops to make something sweeter without adding bulk.
  • And then there is that Stevia aftertaste.  Once Swerve came out and it didn’t have an aftertaste, I have to admit that I wandered away from Stevia except for some flavored liquid drops that I still have and a brown sugar substitute that I really like.
  • All that said, some of the best sugar free baking products are made with Stevia such as chocolate chips and coffee syrups (see list below)

Which Stevia to buy:

5. Allulose

This is a fairly new, also natural,  sweetener on the market and I just got my first bag recently!  Allulose is found in dried fruits. 

  • Like erythritol it is about 70% as sweet as sugar.  But where I love it is for those recipes that are at risk of crystallizing, such as a baked custard.
  • Because it is partially digested, it can cause digestive issues for some so be careful to not consume in large quantities. 
  • I only use it in recipes where the serving size is small and where I don’t want to see that crystallization effect.
  • It’s still rather hard to find and more expensive than other sweeteners, so buy and use only as needed

Allulose to buy:

The Best Keto Sweeteners that I use myself :

In summary, here are the best sweeteners for keto that I keep in my own pantry:

Sweeteners to Use Sparingly or Avoid for Keto Dieters

Ok, I am not the Keto Police and I even have recipes on this site that have used some of these sweeteners, sometimes because another just wasn’t available and sometimes I just didn’t know any better.  I learn new things as we go here as well!

So try to use these sparingly and get yourself migrated over to the natural sweeteners we have already talked about.

  1. Sucralose
  2. Aspartame
  3. Saccharin
  4. Any sweeteners that end with ‘ose’ like fructose are really a form of sugar
  5. Any sweeteners that end in ‘tol’ (except the ones in the good for keto section above)
  6. Sweeteners that are in small packets.  Even the good sweeteners are sometimes put in packets with dextrose, making them a bad sweetener for you.

  1. I saw a recipe for whey bread in the Women’s World Feb 19th magazine. Problem is, I can’t find any cooking whey in Great Falls, MT. All I’ve found available is whey in giant jars for use when working out. Where can I find something that can be baked at high temps?

    1. I asked Ardie (she is the woman in that article!) about the bread and she said she buys the cheapest whey protein isolate she can find. There isn’t a special ‘baking whey’, as long as it’s whey protein isolate. Many many brands out there! You can find Ardie and many others are doing this amazing lifestyle in my free facebook group:

  2. Great source of information. Too bad 3 of the sweeteners were unavailable as of today on I did manage to order the So Nourished powdered though. Thanks Anita.

    1. I hear you! I’m in Canada as well and have a hard time getting allulose! I hear they sell out quickly so when I see it I grab 2 bags. Glad you got something of what you wanted.

      1. I have been using allulose for quite some time now, & it is by far my favorite sweetener. I do quite a bit of baking & candy making for large groups, as well as a bit for my husband & I- though less & less these days, for us. I have found allulose (on Amazon) in 25# bulk from Hoosier Hill @$5.60 per pound $(139.78) which not only reduces the price, it also means you have it in your pantry for much, much longer! Hope this is useful for you- or someone else. Thank you for all of your wonderful recipes & information~ I’m sure you’re seeing my comments all over lately~ I promise I’m not stalking you =) ! It’s nice to find people I can relate to, & who share enough similarities in cooking style, personality, etc.- relatable I guess. Just found this website today, as it was linked for the Lemon Cheesecake recipe. =) ~Samantha in AZ

        1. Thanks for that info! I do like the allulose the best. I’m in Canada and can’t yet obtain such a large bag but I’m sure I will at some point. Thanks for coming to the site!

        2. Allulose at the Hoosier Hill Website is now $8.00 per pound for the 25 pound box. Everything has gone up so dang much in the last few years.
