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.

    • 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

    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

    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

    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.

      Best wishes


  • 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
