Can I Eat Sugar Free Jello/Jelly on Dukan Diet Attack Phase?

Sugar free jello (jelly) to me is a very welcome addition to the Dukan Diet which can be enjoyed in any phase of the Dukan Diet including the Attack Phase.

You were allowed up to three portions of jello every day.  This guidance has recently changed on the coached UK Dukan Diet.  Sugar free jello has now been put into a group of sugar free treats made up of sugar free jello, sugar free chewing gum and sugar free candy (sweets) and whereas before you could have five pieces of sugar free candy or chewing gum each day with three sugar free jellos you can now only have five in total of the sugar free treats.

Here are a few reasons why I find this food so useful.

  • It comes in a wide variety fruit flavors.  During the Attack and Cruise Phase the only fruits you can eat are goji berries and rhubarb so it is lovely to be able to have a different fruity taste.
  • The colors brighten up your meals particularly in the Attack Phase and on PP days.
  • They make a very welcome alternative quick snack to zero fat yogurt.
  • You can use different molds and different colored jellos to allow a little creativity.
  • You can also make your jello with skim milk to add another twist.
  • They are a useful dessert when younger members of the family come to visit.

To give you some ideas:

  • For Valentine’s Day or a special anniversary you could make small red heart shape jellos in strawberry, cherry or raspberry flavor and serve them with a vanilla custard.
  • For Halloween you could make a suitably gross colored jello in a brain mold.
  • For St Patrick’s Day you can make lime flavored shamrocks.

    Hi Amber,

    Is Jell-O Sugar-Free Instant Pudding & Pie Filling allowed in the Cruise Phase?


    • Amber on March 11, 2014

      Hi Barbara

      No, they are too high in carbs.

      Kind regards


  • Katherine on February 3, 2014

    Can you please explain to me how much a serving is? 3 servings of sugar free jello but what constitutes a serving?

    • Amber on February 3, 2014

      Hi Katherine

      The ready made pots have 10 calories and weigh 175 g so this is what I use as a recommended serving size.

      Best wishes

        Sorry to kind if butt in but I’m wondering what you mean with “ready made pots” because I too am wondering about the sugar free Jello. I’m going to purchase some and want to make sure I’m eating an allowed amount. Thank you!

  • Sharon on January 30, 2014

    I just wanted to let you all know that in the US there is a brand of products called Walden Farms. They make a full line of NO calorie, NO cab, NO fat salad dressings, maple syrup, jellies (all artificial), marshmellow fluff, caramel syrup, and several other products. The salad dressings are a wonderful substitute for mayo, and I have even used them as marinades for both meat and fish. I don’t know if these products are available outside the US, but it’s worth looking into. Thanks for all your help.

    Hi Amber,

    I am on my first week of the second stage, and my weight has not moved. The only thing that I can think of is perhaps the diet fanta I have been drinking. I’ve read that aspertame can make you gain weight. I was wondering what do you think of that. And is there a limit, and also should it be counted with the 5 snacks a day rule or on top of that. I was also wondering what do you, or the Dukan diet think of diet chocolate yogurts?
    What shoul i pay most attention to – the calories (60), the fats (0-1.5%) or the carbohydrates? What is the limit for 100 gram for the last one? Thank you so much.

    • Amber on November 21, 2013

      Hi Maya

      The Diet Fanta details I found on line showed that a 150ml serving had 4 calories. This would mean that it should not be drunk on the Dukan Diet as each serving of diet soda should only contain up to 1 calorie. Dr Dukan also recommends having no more than 3 of these drinks each day.

      Chocolate yogurts are unlikely to be suitable, but when looking for yogurts ignore the calories and go for the one with the lowest fat content and which comes in at less than 7 g of carbs per 100 g.

      Kind regards


  • Ruth on September 12, 2013

    Hi amber,
    how many grams does exactly a portion of free sugar jello corresponds to? I but harltley’s pots, 10cal…but i’m not sure how many could i eat of them per day


    • Amber on September 12, 2013

      Hi Ruth

      I’ve always gone with a pot (175 g) being a serving – having 3 a day is only 30 calories.


  • aishah on September 8, 2013

    Agar agar allowed as a jelly instead od gelatine based ones?

    • Amber on September 8, 2013

      Hi Aishah

      Agar agar can be used to replace gelatin in recipes.

      • maryanne on November 6, 2013

        Hi Amber,
        What about no added sugar preserves/jam?

        • Amber on November 7, 2013

          Hi Maryanne

          These are too high in fruit to be suitable.


          Best wishes


  • Anna on August 24, 2013

    Just to make sure I get it right: jelly is a tolerated item. Three portions of jelly of 92g each + 2 pieces of gum equals 1 tolerated item. This means I can have another tolerated item a day, like a tbs of soy sauce. Am I correct?

    • Amber on August 24, 2013

      Hi Anna

      No jelly and sugar free sweets or gum aren’t tolerated items, you are just allowed up to five of these a day with a maximum of three servings of sugar free jelly/jello in the five items. These foods are allowed in any phase of the diet including the Attack Phase while tolerated items aren’t added until the Cruise Phase.

      Kind regards


      • Anna on August 24, 2013

        Thank you! I think I’m getting confused about jelly, because it’s not listed on UK or French site as allowable item, only US, same as gelatin.

  • Carolyn on August 8, 2013

    Hi Amber,
    I am starting the attack phase of the diet. This sounded okay to me after reading the book and reading sites on the web. What do you think about mixing sugar fee jello with FF cottage cheese and Fage 0 FF greek yogurt?

    • Amber on August 8, 2013

      Hi Carolyn

      It makes a delicious dessert!


  • sab on June 19, 2013

    hi amber! can we use weight watchers jelly i have blackcurrant which is with sugar & sweetners? 6 cals per 100gram 0.6 carbs & 0.1 of which sugars? the strawberry & rasperry have 6 cals but 1.5 carbs????

    • Amber on June 20, 2013

      Hi Sab

      Sugar free jello has no carbs so I wouldn’t use Weight watchers as an alternative.

      Best wishes


      • sab on June 20, 2013

        problem is i follow a halal diet so im finding it difficult to find jelly & geletine thats suitable for vegetarians! any advice?

        • Amber on June 22, 2013

          Hi Sab

          In that case you’ll need to be a little more flexible when following the diet and use the best alternatives you can find.

          Best wishes


    • sab on June 22, 2013

      hi amber! i have managed to find hartleys ready made jelly which is suitable for vegetarians 10 cals a pot mango n passion flavour. would that be ok to eat on the attack phase thanks

      • Amber on June 23, 2013

        Hi Sab

        These will be fine to use.

        Best wishes


  • Ronda on April 27, 2013

    I was wondering if I could use protein powder mixed in my sugar free jello to give me a good protein snack. i’m a bariatric patient who suddenly stopped losing weight after I had a complete hysterectomy and am desperate to get back on the losing track. A year after my hysterectomy I had knee surgery and then 9 months after that I broke my foot. However, I’ve been back to full health for a while and am getting back into regular exercise and eating right. Thanks for any advice.

    • Amber on April 28, 2013

      Hi Ronda

      I’m glad to hear that you are back in full health after everything that has happen to you. Unfortunately protein powder isn’t an allowed food on the Dukan Diet and Dr Dukan strongly disapproves of it as he doesn’t consider it to be real food. However you need to be guided by what your own doctor is advising as the bariatric procedure you had may mean you have different dietary requirements.

      Putting a scoop of protein powder into your sugar free jello would put over 100 additional calories into your daily intake and add additional fat and carbs too. I’ve provided details of nutritional information from below

      “Optimum Nutrition
      Protein Powder (100% Whey Protein)


      There are 120 calories in a 1 scoop serving of Optimum Nutrition Protein Powder (100% Whey Protein).
      Calorie breakdown: 7% fat, 29% carbs, 64% protein.”

      Having a protein powder as a snack could very easily stop you feeling hungry when you should be having your meal and throw out the development of good eating habits. It could lead to you skipping a meal which then leaves you feeling excessively hungry so that you over compensate at the next meal.

    Hi Amber,

    Is Jell-O Sugar-Free Instant Pudding & Pie Filling allowed in the Cruise Phase?

    Thanks :)

  • Renee on March 28, 2012

    I am just starting the attack phase and am wondering if I can have as much greek yogurt, cottage cheese, and protein meats (from the list) as I want or are there also limits to these too?

    Where can I find the list of extra items I can have like jello? I don’t see jello on the approved food list?



  • Amber on January 15, 2012

    Hi there,
    Great site! A wealth of information. I am in NZ so a lot of the discussed products are not available here etc. We have a comparable sugar free jelly (jello) but are you able to tell me what quantity is considered a portion?
    Thanks :)

    • Amber on January 15, 2012

      Hi Amber


      A portion of US Jello in a pot has 10 calories and is 92g.

      Hope this helps!


  • Carol on October 18, 2011

    Hi Amber, I understand that we can eat sugar free Jello but can we eat all of the flavors during the cruise phase? I like lime and black cherry but am not sure they are allowed during this phase.


    • Amber on October 18, 2011

      Hi Carol

      Dr Dukan hasn’t advised that any flavors are off limits and as far as I can tell they all have the same calories per serving.

      Kind regards


  • Tig on August 3, 2011

    Hi Amber,

    I have just completed 5 days on the Attack phase and am starting the cruise phase tomorrow (Yippee I can eat veggies) also I’ve lost 11lb :0) My question is can I drink Robinsons no sugar squashes? If not is there any thing else cold I can drink as I am getting bored of just water,


    • Amber on August 4, 2011

      Hi Tig

      Although the squashes don’t contain any added sugar this doesn’t mean they are sugar free. Dr Dukan allows 3 diet drinks per day of less than 1 calorie per serving so the squash doesn’t meet this rule, but it does mean that you can find something to drink something a little different than water. I enjoy green tea and fruit teas but I know these aren’t to everyone taste.

      Congratulations and keep up the good work.


  • Kayleigh on July 28, 2011

    Hi Amber,

    How many teaspoons of sweetener are you allowed per day.

    I find myself putting alot in my yoghurt!

    • Amber on July 28, 2011

      Hi Kayleigh

      The US FDA has set an accepted daily intake (ADI) for sucralose (Splenda) at 5 mg per kg of body weight per day. To find your ADI for Splenda, divide your weight in pounds by 2.2 and then multiply it by 5. For example, if a person weighs 165 lbs, their weight is 75 kilograms (165 divided by 2.2) so their ADI for sucralose is 375 mg (75 x 5). Each one gram packet of Splenda contains 11.9 mg of sucralose, so the 165 lb person could have 31.5 packets of Splenda a day.


  • Ammoff on June 5, 2011

    I recently purchased the Dukan Diet book and have successfully made it through the attack phase for 6 days, as of day 12 I still have been able to keep to the menus in the book and have lost a total of 8 lbs. I have been unable to exercise for the past 4 days due to being sick with a middle ear infection. I am craving fruits more then ever. Is there any fruits such as watermelons or all of the melon family that I can eat while on the cruise phase?

    • Amber on June 5, 2011

      Hi Ammoff

      You’ve done extremely well to stick to the diet whilst you’ve been feeling under the weather. Losing 8lbs is a great start.

      Unfortunately there are only two fruits you can have in the Cruise Phase and these are goji berries and rhubarb. You can also have two fruit yogurts each day as your tolerated items, fruity diet drinks that have less than 1 calorie per glass and as this post explains you can have up to three sugar free jellos.

      I don’t know if you like milkshakes but you could try putting a carton of your favorite fruit flavor low fat, no sugar yogurt in a blender with skim milk, a couple of teaspoon of skim milk powder and a little ice. You just mix until frothy and enjoy!

      I hope that you are soon feeling better.

      Take care
