What Sweeteners Can You Use on the Dukan Diet

My UK version of the Dukan Diet book advises that aspartame is the only sweetener that you can use on the diet. Dr Dukan advises that it is the best known and most widely used sweetener in the world and that it can be used without any restriction.

However as you may know if you’ve read some of my other posts, my copy of the book is not the only source that I use to provide information for the site. I find that the online chats, that take place three times a week with the Dukan coaches at www.dukandiet.co.uk, keep me up to date with many of the latest adaptations made.

If you don’t like aspartame you might find the information which follows very helpful. I’m providing edited extracts from two fairly recent online chats which add Stevia, Splenda(Sucralose) and Xylitol to the list of sweeteners which can be used. I know that a lot of people prefer using Xylitol or Stevia because they are natural products.

Q: I’m in the Cruise phase. Can I use “Sweet Freedom” a natural sweetener. Made from 100% fruit. 1tsp 13 cal, 4 carb, 4 which sugars & 0 fat. Made by diet freedom.
A : I’m sorry but this is not allowed at all as it’s pure sugar. Try to use some sweeteners such as Stevia or Splenda it’s quite nice. Keep going and have a nice Sunday!

Q : Can I have agave syrup?
A : Hi! I’m sorry but agave syrup is too sugary to be allowed. Then if you like natural sweeteners I suggest you to use some stevia or some xylithol these are really nice.Enjoy!

    Hi amber are sussli sweeteners allowed

    • Amber on October 28, 2014

      Hi Jatou

      I’ve not been able to find any information for this product. Are they calorie free? If so you can use them.

      Kind regards


  • Julie on September 21, 2014

    I’ve tried to search the internet for an answer, but nowhere can I find any information on the use of liqourice powder during the Dukan diet. So my question is; can I eat raw liqourice powder (pulverized liqourice root) during the first and second phase? It is naturally very sweet and I’d like to use a teaspoon or so in my youghurt.
    Thx a million 🙂

    • Amber on September 22, 2014

      Hi Julie

      Licorice/liquorice root contains a unique substance called glycyrrhizin which has been found to be 50 times sweeter than refined sugar. The glycyrrhizin has no calories, but the natural licorice root does contain a few calories due to the presence of a very small amount of dextrose (1.4%) and sucrose (3.2%). The dextrose and sucrose would make the licorice root unsuitable to use on the Dukan Diet. A teaspoon has 5 calories.

      • Paulina on January 7, 2018

        I was curious about liquorice root as a potential sweetener, too. The Dukan Diet Natural Slimming Tea mix contains said liquorice root, but with each tea bag weighing about 2g, it’s probably a negligible amount in tea, though. It’s a common ingredient in herbal medicine products for its good flavor and natural sweetness to cover the “grassy”, or “bitter” aroma of other, less pleasant tasting herbs. Liquorice is however not recommended for pregnant women, so it’s been off the menu for me for a while. I don’t know if the recommendations have shifted in 3+ years, but if you find out, please let us know.

        • Amber on January 8, 2018

          Hi Paulina

          I’ve looked at whether this sweetener would be suitable for use in pregnancy as requested and it is still considered to be unsafe during pregnancy. This is because it may mimic the effects of estrogen, a female sex hormone, and may induce premature labor in pregnant women.

          It is not unusual to see the occasional ingredient in Dukan products that doesn’t meet the strict rules.

      Hi Jancy

      The sweeteners used should be calorie free so this product is not suitable.

      Kind regards

          Yes these are fine to use.

    Hey !
    I have a question !
    Is Sugar in the raw allowed on the diet ??
    Please I need an answer !!

    • Amber on May 5, 2014

      Hi Sara S

      No type of sugar is allowed including Sugar in the Raw.

      Kind regards


  • Lee Mullen on February 21, 2013

    Hi, how much Erythritol and Stevia crystalised sweetener can be consumed per day?

    Also, is there any limit on how much Balsamic vinegar to be eaten?

    • Amber on February 21, 2013

      Hi Lee

      There is no limit on sweeteners in the original diet but the Dukan coaches do recommend that you try to limit the amount used to between 8 and 12 teaspoons a day. Part of the success in keeping off the weight long term will come from teaching yourself new eating habits and reducing the amount of sweet food you eat will definitely help.

      Balsamic vinegar does have quite a high sugar level so it is best to try to limit yourself to around a tablespoon a day.

      Kind regards


  • Sara on January 6, 2013

    Hi… I am new and just starting this diet.. as far as the sweeteners …… any advice for someone highly allergic to aspartame /sucralose /nitrate sweet….. I have always just stayed away from artificial sweeteners because of my severe allergic reaction……

    • Amber on January 6, 2013

      Hi Sara

      As well as being a high protein diet the Dukan Diet is also low in carbs and this is why sugar is not allowed. Any forms of sugar that you add because you are unable to use sweeteners will reduce the effectiveness of the diet.

      In view of your severe allergic reaction it is probably best for you to steer well clear of all of the sweeteners including those based on natural products such as Stevia.

      Kind regards


  • eli on October 11, 2012

    Hi and thank you very much for these information…. i wanna know is ” sweet and low” ok in dunkan diet ?! Because i have not heared of it in your website or recepies….. 🙁 and i do not have access to other kind of artificial sweeteners you recommend .

  • Anastasia on October 2, 2012

    Hi Amber,

    I have two questions.
    The first it’s if I am allowed okra at the 2nd phase?
    Second I have insuline resistance problem and I am getting pills for that (their name is Glucophage). Do you know if this can sabotage my diet?

    Thanks a lot xxxxxxxxx

    • Amber on October 2, 2012

      Hi Anastasia

      I’m sorry but okra (ladies fingers) are too starchy for the weight loss phase of the Dukan Diet.

      Weight gain isn’t a known side effect of Glucophage aka Metformin and the information in this link advises it is sometimes even prescribed to aid weight loss

  • sue on July 30, 2012

    is canderel zero calories allowed as a sweetener?

    I got skimmed milk and it is labeled 19% fat per 100g. Is it ok for coffee and how many cups can I have per day

    • Amber on July 30, 2012

      Hi Sue

      Canderel is fine to use but I’m really confused by your milk which has an extraordinarily high fat content and is not suitable to use. Skimmed milk powder has 0.6g fat per 100g and skimmed milk has 0.1g of fat per 100ml.

      Kind regards


  • Bec on April 21, 2012

    I’ve been doing the Dukan diet for 11 days now and I have only lost 2 kg, the yogurt I’ve been having is fat free but sweetened with phenylalanine – is this ok? It is low sugar but still has 6.6g per 150g. Could this be why I’ve only lost 2 kg? I only have about 10 kilos to lose in total. Can I have this yogurt as much as I want as I’ve been having it after every meal.
    Thanks heaps
    Kind regards

    • Amber on April 22, 2012

      Hi Bec

      Phenylalanine makes up 50% of aspartame so this shouldn’t be causing any problem. Too much dairy can slow down weight loss and this is why the Dukan coaches recommend a daily limit of 1 kg. You could try reducing this limit to 500g and see if this helps but as you need to lose 10 kg (22 pounds) to lose 2 kg (4.4 pounds) in 11 days is not out of the range of weight loss that people experience. How we lose or gain weight is quite complex and depends upon many things such as our hormones, the salt our food contains, how much exercise we do, the medicines we take and our digestive systems.

      Stay strong and stick with the diet and the weight loss will follow.

  • Amber on January 3, 2012


    Just wondering if you can use sweetners during the attack phase, if so how much and any recommendations?

    Many thanks,


    • Amber on January 4, 2012

      Hi Amber

      Yes you can use sweeteners in any phase of the Dukan Diet but Dr Dukan recommends no more than 8 teaspoons a day to get your body used to eating less sweet things. Sweeteners are a matter of personal choice as some people won’t use aspartame because of the bad press, others find certain ones leave a taste in their mouth and others like to use Stevia as it is a natural product. Also some sweeteners are also better if used for cooking.

      • ettie on February 10, 2014

        can I use honey?
        can I use fruit sugar?

        I have Celiac disease – what can I use instead of oat bran?
        can I use Chia bens instead of oat bran?

        • Amber on February 10, 2014

          Hi Ettie

          I’m sorry but honey, fruit sugar and chia seeds are not allowed. There is no official alternative to oat bran although I know of many people who have used psyllium husk to add fiber to their diet when they are unable to eat oat bran.

          Kind regards


  • Alex on December 27, 2011

    How do I replace Splenda with stevia in the oat bran and oat bran muffin recipes?

    • Amber on December 27, 2011

      Hi Alex

      I’ve never used Stevia so I’m unable to help out with quantities to use. I would suggest experimenting until you get the level of sweetness that you like.

      Kind regards


  • Hira on October 15, 2011


    Can you please tell me if EQUALS is an ok sweetner

    • Amber on October 15, 2011

      Hi Hira

      I’ve just checked the ingredients of Equal Sucralose and Splenda which I know the UK Dukan coaches have OK’d and they are the same. They both contain maltodextrin which is a sugar but it must be in very small amounts.


  • kimmy on September 22, 2011


    thanks you so much for your website. it is really good.
    I am using SUGARLESS SWEET AS. The ingredients per sachet is: lactose, sweetener (aspartame 3.8%), tri calcium phosphate. Is this acceptable?

    Thank you

    • Amber on September 22, 2011

      Hi Kimmy

      I’ve not heard of Sugarless Sweet As before but it is quite common for a bulking agent to be added to sweeteners. I’ve copied an extract from the Splenda site below:

      “Like other tabletop sweeteners, the granulated and packet products contain small amounts of carbohydrate (less than 1 gram per serving) for consistent sweetening and to provide volume. These bulking ingredients are dextrose (packets) and maltodextrin (packets and granulated). However, the bulking ingredients provide so few calories per serving that the FDA allows the SPLENDA® No Calorie Sweetener Products to be labeled no calorie sweeteners, because they provide less than five calories per serving”

      As Splenda is allowed it seems to make sense that Sugarless Sweet As should also be allowed.
