Can I Have Milk in the Dukan Diet Attack Phase?

This question came to me via Google as a person typed this question in Google and ended up on my site.  Hopefully they found the information they were looking for.  It was the various questions that I found in the Google Analytics data that made me think that visitors to the site might find FAQ  posts on Dukan Diet useful.

The answer to the question, can I have milk in the Dukan Diet Attack Phase is yes provided that it skim milk.  Skim milk is also known as zero fat or skimmed milk.

Milk is an excellent source of protein, calcium and various vitamins and minerals and skim milk should be an integral part of all dieters’ daily menu.  Just one glass of this super food contains:

  • 30% of your daily requirement of calcium which you need to build and maintain your bones.
  • 25% of the Vitamin D needed by your body to help it absorb various minerals such as calcium.
  • 24% of your Riboflavin needs.  Riboflavin helps you to use your food to create energy.
  • 20% of the daily quantity of Phosphorous needed to strengthen your bones and generate energy in your body cells.
  • 16% of your body’s Protein needs in two different forms, whey and casein.
  • 13% of the daily requirements of Vitamin B-12.  This vitamin helps build the red blood cells that carry oxygen around your body.
  • 11% of the daily amount of Potassium required.  Potassium helps your body maintain normal blood pressure.
  • 10% of the Niacin needed which helps you metabolise fatty acids and sugars.
  • 10% of the daily needs of Vitamin A which helps to maintain healthy eyes and skin.

The reason that skim milk is the slimmer’s friend is that it contains almost the same nutritional value as whole milk without the fat content.   This also makes it suitable for anyone who is watching their cholesterol.

    Is powdered milk allowed during phase one??

    • Amber on September 16, 2017

      Hi Amal

      You can use powdered milk but be careful with the amount of dairy being consumed.

    Hi Amber
    We all really appreciate your help with the diet! You site is amazing! I am now in the cruise phase.
    I have a couple questions:
    1) Oat milk – can I drink oat milk in the morning? To substitute the oats that we need to take daily
    2) Skimmed milk – the non fat cow’s milk – can I have as much of it during the day as I want or is there a limit?
    3) Is there any food that you would suggest we really can have as much as we want and it’s the best to fill you up?
    Thanks so much in advance

    • Amber on July 18, 2017

      Hi Leila

      To answer your questions

      1 – No it is oat bran or nothing. There are no approved substitutes.

      2 – you can have unlimited quantities of milk but it could slow weight loss so the daily recommended limit is 1 kg of dairy protein foods. If a food is in ml treat 1 ml as equal to 1 g.

      Kind regards

    Can you put low fat raw cacao powder in the skimmed yoghurt In the attack phase?
    Thank you 🙂

    • Amber on July 14, 2017

      Hi Diana

      Cocoa powder isn’t added until Cruise where it is a tolerated item. So I’m sorry the answer is no you can’t.

      Best wishes

    Can I have goat milk in attack or cruise phase?

    • Amber on November 19, 2015

      Hi Morgan

      Sorry no. The only replacement for cow’s milk is soy.

      Kind regards


    • Morgan on January 15, 2017

      Organic 2% fat milk is ok?

      • Amber on January 16, 2017

        Hi Morgan

        2% is ok – skimmed is better:)

  • Ginger on October 22, 2015

    Amber – for milk, I just want to confirm, you said we’re allowed dairy of 1 kg or less per day. (1 ml is treated as equalling 1 g). Does that mean we’re allowed up to a liter of milk per day? If 1 ml is treated as 1g, and 1000g = 1kg, then 1000ml = 1 liter? That seemed like a lot but wonderful if its true!!

    • Amber on November 5, 2015

      Hi Ginger

      Yes it is true.



  • Cij on April 20, 2015


    I have just realised that its only fat-free milk that I am meant to take in terms of milk. I have been using semi-skimmed to satisfy my snack cravings for the past three days on the attack phase. Does it mean it has all been a waste?



    • Amber on April 23, 2015

      HI Cij

      Fat free is best but in some countries you can only buy semi skimmed so products with up to 2% fat content are OK to use.

      Best wishes


  • don.d on January 13, 2015

    Hello. Is 2% milk allowed in the attack phase. Please and Thanks

    • Amber on January 17, 2015

      Hi Don.d

      You can use dairy products with up to 2% fat content but 0% is best.

      Kind regards


  • Kawther on January 6, 2015

    I was just wondering.. All the types of skimmed milk that I found in UK (powder and liquid) contain sugar which is the same or even more than amount of proteins. I just want to be sure that drinking that milk won’t destroy what i’ve achieved so far..
    Thanks in advance,

    • Amber on January 7, 2015

      Hi Kawther

      All dairy products contain natural sugar due to the lactose that milk contains so you don’t need to avoid this food. However try to limit the amount of dairy products consumed to 1 kg or less per day. (1 ml is treated as equalling 1 g).

      Kind regards


  • Maya on October 13, 2014

    Hi amber,

    Can you tell me what I should look out for when buying powdered skim milk. I need it for a recipe and want to make sure the carb/fat numbers are correct.
    Thank you.

    • Amber on October 13, 2014

      Hi Maya

      You only need to look for a product that is 100% powdered skim milk, possibly with added vitamins, there are no figures for carbs or fat to check.

      Best wishes


      • Maya on October 14, 2014

        Great ! thank you 🙂

  • Sanu on July 22, 2014

    ive just started the dukan diet and it is day 2 for me on attck phase. does it get any easier? also is it normal to feel sick and have headaches?

    • Amber on July 23, 2014

      Hi Sanu

      The drastic reduction in carbohydrates can cause some headaches/nausea as your body adjusts but if the problem doesn’t disappear with the next couple of days you should consider changing diet plans and a check up with your doctor to confirm that the lack of carbohydrates was the problem.

      Kind regards

    I am a bit of mixed up between the consolidation phase and the stabilization phase.
    In the consolidation phase as far as I understood, we have 6 PV days out of 7, but we add in these 6 day: one portion of fruit, normal cheese and about half a baguette. Only once per week we must have only pure proteins(without the added options). Also once a week we can add 200 g of starchy meal, and another day of the week we have the celebration meal added.
    However, in the stabilization phase, we can eat anything we want during 6 days of the week, but only once a week we have it as pure proteins with nothing else added.

    Please correct me if i am wrong.

    Thank you

    • Amber on April 3, 2014

      Hi Marwa

      You do have an understanding of the differences between these two phases. However if you eat excessively on Stabilisation the one day of pure proteins won’t be enough to keep your weight stable.

      Kind regards


  • Honey on October 24, 2013

    Is it permitted to have skim Lactaid on the Dukan diet?

    • Amber on October 24, 2013

      Hi Honey

      I’ve checked the nutritional information for this milk and it is almost identical to normal skimmed milk. Because of this I’d give it a thumbs up!

      Kind regards


      • Mary S on January 8, 2015

        The problem w/ products like Lactaid is that the enzyme treatment they get to break down the lactose turns that slow-burning lactose into the component sugars glucose and galactose–turning slow carbs into fast ones. These will all be listed on the labels as carbs/sugars but will most likely perform differently in the body. You could try soy milk, which should be lactose-free (as always, check your labels); I’ve never used it so I don’t know how it tastes.

        • Amber on January 11, 2015

          Hi Mary

          I didn’t know this – thanks for sharing:)

  • Emma on September 3, 2013

    I am eating real food I just rush over lunch time from getting my son to nursery then I go straight to work so don’t get to grab anything to eat untill tea time

  • Emma on September 3, 2013

    Hi I’m on the attack phase can I have a protein shake using skim milk?

    • Amber on September 3, 2013

      Hi Emma

      I’m afraid protein shakes aren’t allowed on the Dukan Diet you have to eat real food.

      Kind regards


  • Dana on September 2, 2013

    Hi Amber.

    I’m gonna try this diet, but I want to make sure that I do it right.

    In the Attack Phase you’re suppose to eat only protein, like chicken, egg, dairy etc.

    In the cruise phase you must still eat protein but add some vegetables.

    In the consolidation phase you must add some fruit

    And in the stabilization phase you can eat whatever you want, but once a week you have to eat only protein. Each phase must last at least 10 days.

    Did I get the plan right?

    • Amber on September 3, 2013

      Hi Dana

      You have the basic understanding of the diet but you need to do a little more research to fill in the gaps.

      Best wishes


  • Tara on August 30, 2013

    Hi Amber 🙂

    I was wondering if Skimmed milk during the cruise phase is part of the ‘tolerated foods lists’ and wether there is a limit on the quantity were allowed to consume?

    Thank you for your time !

    • Amber on August 30, 2013

      Hi Tara

      Skimmed milk is not a tolerated item. In the books there is no daily limit on the approved dairy proteins consumed but in the coached version there is a daily limit of 1 kg. I recommended using the 1 kg limit. For calculation purposes treat 1 ml as 1 g.

      Kind regards


  • Jason on August 27, 2013


    I’m in the attack phase and wondered if I can eat packet sugar free instant whip using skimmed milk?


    • Amber on August 27, 2013

      Hi Jason

      These types desserts are too high in carbs to be sutiable even without the sugar:(

      Kind regards
