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.

    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.

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

      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

    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.

    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

    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
