Sugar Substitutes and Sweeteners for the Dukan Diet

There are so many different sugar substitutes available that working out which ones are allowed on the Dukan Diet is not easy but if you have a copy of one of Dr Dukan’s books you might think that aspartame is the only approved sweetener.  Both of the books that I have copies of, The Dukan Diet (UK version) and The Dukan Diet Life Plan, only lists aspartame when advising of the sweeteners which can be used.

Aspartame is an artificial sweetener which is surrounded by a lot of controversy and because of this many people are not comfortable using aspartame and many others also prefer to use natural products.  However not all natural sugar substitutes are suitable to use on the Dukan Diet as many of these natural products still contain a lot of sugar.

The list of acceptable sugar substitutes and sweeteners below comes from official Dukan Diet sources. The primary source of the information posted comes from the Dukan Diet – US Facebook Pages.  I’ve also listed the brand names of various sweeteners that are permitted on the Dukan Diet.  If there is a brand that I’ve not listed that you would like to know is OK to use, use the comment box below to give me the name and if possible the ingredients and I’ll check it out and add it to the list if it is an acceptable sweetener to use.

In the books there is no limit on the amount of sweeteners that you can use but for the coached version there is a limit of 12 teaspoons, which was previously 8.  The advice on this topic has changed recently as in an online coaching chat one of the Dukan coaches advised that artificial sweeteners such as Splenda and Equal were limited to 6 packets a day(12 teaspoons) but that all natural sweeteners such as Stevia and Lohan are unlimited.

You’ll find that many of the Dukan approved sugar substitutes contain small amounts of other sugars such as maltodextrin or dextrose which are not normally allowed.

      Apparently is 0 on everything, I think its ok by I would like your opinion before purchase 🙂

      • Amber on February 3, 2018

        Hi Andrea

        This one is fine:)



  • Olga on January 19, 2018

    Hello Amber, I was wondering about Truvia it has Erythritol, Sugar, Stevia leave extract in ingredients and still allowed on Dukan? Thank you.

    • Amber on January 20, 2018

      Hi Olga

      Although it contains sugar the nutritional information states that Truvia is a calorie free sweetener so I’d say it is fine to use.

  • Lina on January 12, 2018

    Can you tell me if maltodextrin in sweeteners is ok?
    Thank you in advance.

    • Amber on January 13, 2018

      Hi Lina

      The area of sweeteners is a little confusing. If the sweetener is zero calorie I’d say it is OK regardless of the ingredients.



      • Lina on January 13, 2018

        Thanks for your answer.

  • Siavash on October 27, 2017

    Thanks for your great website. I am on my Cruise phase and this website has been much helpful for me.

    I am using sucralose (Canderel brand) for baking my dukan galette or sometimes sweetening my fat free yogurt. I don’t like sweetening my tea or coffee though. Instead I found a sugar free small candies that I like to put one in mouth and drink my tea or coffee through it. But these candies have Isomalt. In one of the comments here you say that isomalt is not allowed. I just wonder how maltitol is allowed but isomalt is not? Both are half as caloric as sugar and have lesser effect on blood sugar. I believe that Isomalt has even lesser effect on Insulin compared to maltitol.

    Thanks in advance for answering my question

    • Amber on October 29, 2017

      Hi Siavash

      The Dukan Diet often doesn’t make sense and is contradictory. This was one of the reasons I started this site. Based on the information you’ve provided I see no reason not to use the candies made with isomalt.

          Yes you can use any zero calorie sweetener.

    I’ve just found a brown sugar substitute in the Uk called Sukrin Gold.

    Ingredients are: Sukrin Granulated (Polyol-Erythritol, Tagatose, Glycerol, Malt extract (gluten free), Stevia steviol glycosides (Rebaudioside A)

    Nutritional values per 100g:
    Energy 8kcal / 35kj
    Fat 0.0g
    of which saturates 0.0g
    Carbs 99.3g
    of which sugars 2.9g
    of which polyols 96.4g
    Fibre 0.0g
    Protein 0.1g
    Salt 0.0g

    Is it okay to use in baking?

    • Amber on October 7, 2017

      Hi Sarah

      In small quantities this would be treated as a zero calorie sweetener so I’d say it should be OK.



  • Jerry on June 3, 2017

    I read above that we can use xylitol then further below it says we that we can’t. I don’t like the after taste of many sugar free substitutes, but xylitol I can easily tolerate.

    • Amber on June 11, 2017

      Hi Jerry

      The Dukan is very contradictory. Xylitol is not the best choice to reduce calories as it is still quite high in calories. Try it use it as little as possible if it is the only sugar substitute you can use.

      Kind regards


      • Connie Marrocco on June 12, 2017

        Is it ok to use Splenda brown sugar. If so how much.

        • Amber on June 13, 2017

          Hi Connie

          Splenda Brown sugar is part brown sugar and part sweetener so it is still high in calories and carbs. This means it needs to be avoided.

          Best wishes


  • Bibi on April 26, 2017

    Hi I bought this Sweetener called Natvia
    It has Erythritol and steviol glycosides1.4%

    It says zero calories but carbohydrates are 98.6g per 100 grams and 2.96g per 3g( which is a teaspoon)
    So is it allowed and is it good for blood sugars?

    • Amber on April 29, 2017

      HI Bibi
      Here is an extract which may help from
      “Are Sugar Alcohols Calorie-Free?

      Sugar alcohols, such as erythritol, maltitol, sorbitol, and xylitol are also considered carbohydrates and—like fiber—are included in the total carbohydrates on the label. (It’s easy to spot them in ingredient lists because they almost all end with –ol.) However, sugar alcohols don’t provide four calories per gram. For example, erythritol contains less than a half a calorie per gram; some of the others have up to 3. In any case, a food sweetened with sugar alcohols will contain fewer than four calories per gram of carbohydrate.”

      If the sweetener says it has zero calories per serving it can be used.



      • Bibi on April 30, 2017

        Thank you so much for reply
        Which sweetener do you personally recommend which is good to use in Dukan and good for diabetics as well
        And what’s guide line to use uncured chicken and how to consume it?thsnk you

        • Amber on May 1, 2017

          Hi Bibi

          Splenda is the brand I use but have a word with your doctor or nurse and ask for their recommendations for a sweetener, they should be up to date with the latest recommendations for diabetics.

          I’ve checked the ingredients in Trader Joe’s Uncured chicken dogs and apart from sesame oil all are OK. However the product has less than 5% fat content so the added oil isn’t a big deal. A purist would also point out the added vegetables would mean it shouldn’t be eaten on a PP day.

  • Avena on March 12, 2017

    This product is Honey tree’s Sugar Free imitation Honey. Ingredients:Maltitol syrup,natural and artificial flavor, acesulfame K,malic acid.

    • Amber on March 12, 2017

      Hi Avena

      Sorry this product isn’t suitable. A 21 g serving has 50 calories and 17 g of carbs.

      Kind regards


  • Grazia on January 20, 2017

    If something is under 5 calories it is listed as 0.
    I found this ! So this means that every aspartame even stevia is at least 2 or 4 kcal

    • Amber on January 20, 2017

      Hi Grazia

      Yes – low calorie foods can be listed as zero calorie. Dr Dukan’s only rule about sweeteners is that they have to be zero calorie.

      kind regards


  • tat on November 11, 2015

    is sugarless allowed?

    • Amber on November 19, 2015

      Hi tat

      The liquid Sugarless has zero calories so would be fine to use. The other products contain a small amount of calories.

      Kind regards


  • Mia Gonzalez on September 15, 2015

    Hi Amber,

    Please let me know if I can do a vegan shake called Aloha. I bought it online and it has 4 grams of sugar from coconut. Can you please look at the ingredients online and let me know what you think.



    • Amber on September 25, 2015

      Hi Mia
      The Original Greens contains Coconut Water, Peas, Wheatgrass Juice, Spinach, Moringa, Spirulina, Blueberries, Oyster Mushrooms, King Trumpet Mushrooms, Enoki Mushrooms, Raspberry Juice, Xanthan Gum, Vanilla Bean, Himalayan Pink Salt, Lemon Juice, Hawaiian Yellow Ginger.

      Based on these ingredients it would not be suitables as some of the ingredeints are not permitted such as coconut water, peas, blueberries, raspbery juice and lemon juice.

      Kind regards


  • khaled on August 12, 2015

    Hi Amber

    Is lactitol sugar substitute allowed in dukan diet , and is there really a carb net in PV days ?

    • Amber on August 16, 2015

      Hi Khaled

      No lactitol has about half the calories of sugar but it isn’t a zero calorie sweeener.

      I’ve not heard of a carb netting being applied to the Dukan on any day.

      Kind regards


  • Eilera on June 8, 2015

    Hi Amber,

    As I understand only 0 calorie sweeteners are allowed, but most of the brands mentioned, including my favourite Stevia sweetener like SwertLeaf or even Splenda that advertise as 0 calorie sweeteners actually have calories when you read the nutritional information
    Much less than sugar, but they’re still present. Are they allowed on the Dukan diet? I have checked nearly every product from the listed brands that are sold here in Ireland. xx

    • Amber on June 16, 2015

      Hi Eilera

      Provided a serving is stated to provide zero calories you can use them.

      Kind regards


  • Kylie on February 16, 2015

    What about Isomalt?

    • Amber on February 16, 2015

      Hi Kylie

      Isomalt does have less calories than sugar but it isn’t a zero calorie sweetener so it isn’t suitable to use on the Dukan Diet.

  • sarah on January 13, 2015

    Hello Amber 🙂
    Are products containing Glucose sugar aloud?
    Thank you for all the help, this site is great!

    • Amber on January 17, 2015

      Hi Sarah

      Sorry no.

      Best wishes


  • linda on November 8, 2014

    How about natural caramelized sugar that you can find in quorn mince?
    Thank you.

    • Amber on November 13, 2014

      Hi Linda

      Dr Dukan had to adjust his diet to make it suitable for vegetarians so the foods that vegetarians eat do not necessarily fully comply with the rules of the standard Dukan Diet.

      Kind regards


  • jatou on October 21, 2014

    Hi amber are sussli sweetener tablets allowed

    • Amber on October 28, 2014

      Hi Jatou

      I can’t find the nutritional information for this sweetener. If it is a zero calorie sweetener it will be fine to use.

      Best wishes


  • Cosmin on September 13, 2014

    What about sorbitol? It is also found in some Dukan products, but it has 99.5% carbs, so I guess is not allowed. I really don’t understand how they use it in those products…

    • Amber on September 14, 2014

      Hi Cosmin

      Sorbitol has less calories than sugar but it wouldn’t be suitable to use in large quantities you need to use a zero calorie sweetener for daily use. The amounts in the Dukan products is likely to be very small.

      Kind regards


      • Cosmin on September 21, 2014

        Thamk you! How about erythritol? It’s almost 100% carbs, just like sugar, even though it has no calories. Is this really allowed?

  • Calli on July 27, 2014

    Hello Amber : )
    Is Brown Sugar Splenda allowed?

    • Amber on July 27, 2014

      Hi Calli

      Sorry no, it is a reduced calorie rather than calorie free sweetener.

      Kind regards


  • sasha on June 23, 2014

    I found this peach ice tea drink mix that is sugar free and has aspartame and has 5 calories per packet. Can i have this in my water?

    • Amber on June 24, 2014

      Hi Sasha

      The calorie count would mean that it should not be used. Diet drinks should have one calorie or less per serving but not everyone sticks to this rule.

      Best wishes
