How Much Oat Bran Do You Eat on the Dukan Diet?

Visitors to the site have been looking for more information about oat bran and for recipes using oat bran so this is going to be the topic of my next few postings. One visitor was looking for the answer to whether you can eat unlimited oat bran on the Dukan Diet. The simple answer to this is no you can’t.

You eat oat bran in every phase or stage of the Dukan Diet and increase the amount of oat bran that you eat as you progress through the stages, but the amount of oat bran you can eat in each phase is restricted. Although oat bran does have a beneficial impact you can have too much of a good thing and exceeding the prescribed limits of oat bran, in any phase of the diet, can stop you losing weight or even see your weight start to creep up again.

It is important to remember that the Dukan Diet is a high protein, low fat, low carb eating plan and oat bran is a carbohydrate.

In the Attack Phase or Phase 1 you can eat 1.5 tablespoons every day and this increases by 0.5 tablespoon as you progress through the other Phases. Cruise Phase or Phase 2 is 2 tablespoons, Consolidation Phase or Phase 3 is 2.5 tablespoons and Stabilisation Phase or Phase 4 is 3 tablespoons.

You can add extra oat bran to your diet after the Attack Phase by using your daily tolerated items allowance. Two additional tablespoons of oat bran are considered as one of your two tolerated items.

    I heard that we can have an extra serving of oat bran has a tolerated food item and to increase water even more. Then I heard that it is no longer true. Which is it please?

    • Amber on January 8, 2018

      Hi Diana

      There was a time when additional oat bran was allowed but it was found to be slowing down weight loss so it was removed from the list of tolerated foods.

    • Amber on September 25, 2017

      Hi Meric

      That is correct.

    Hi, I’ve got a question about the dukan cereal bars he sells on his site. On his site ne seems to suggest you can have an oat b ran cereal bar on top of yiur 2 tablespoons of oat bran a day? Is that correct? Thx

    • Amber on August 28, 2017

      Hi Jonno

      Yes you can have these in addition to your daily oat bran but treat them as your daily tolerated items in Cruise.

      Kind regards

    I have a wheat grinder and can grind oats of any kind. Can I grind my steel cut oats and use that as oat bran? I really would like to use what I’ve got.
    Also I have soaked wheat berries, which are full of protein. Can they be used on PP days?


    • Amber on April 8, 2017

      Hi Susan

      Ground steel cut oats aren’t the same as oat bran so it isn’t a swap I could approve and wheat berries are too high in carbs to be suitable for inclusion in the Dukan.

      Kind regards


  • Zainab on February 12, 2017

    Hello Amber,

    Please can I skip oat bran all together or is there an alternative? I can’t seem to find any where I am.

    This is my second attempt at the Dukan. I’m starting tomorrow.

    Thank you.

    • Amber on February 13, 2017

      Hi Zainab

      You can leave the oat bran out of the Dukan if needed as there are no substitutes.

      Kind regards


      • Zainab on February 28, 2017

        Hi Amber,

        Thank you!! I found some eventually and wheat bran too.

        Is it okay to have 1.5 oat bran and 1 wheat bran.

        Thank you,


        • Zainab on February 28, 2017


        • Amber on February 28, 2017

          Hi Zainab

          Yes that will be fine.

          Best wishes


  • Maria on January 9, 2017

    Hi Amber,

    Huge, huge fan of your site. Quick question: how much oat bran does one have on each day of Dukan 2?

    Thanks in advance,


    • Amber on January 10, 2017

      Hi Maria

      Thanks – Have 2 tablespoons each day.

      Best wishes


  • Darna on September 29, 2016

    Hi Amber

    Does it mean I’m restricted to 1 piece of oat barn gallet per day during the attack phase? Since I’m only allowed 1.5 tablespoon of oat bran a day and the recipe for 1 serving of gallet contains 1.5 tablespoon of oat bran.


    • Amber on October 16, 2016

      Hi Darna

      Yes you would only be able to have one galette.



  • Melissa on September 7, 2015


    Can i eat more oat bran than 1.5tbsp ? I really like to have it for my breakfast

    • Amber on September 7, 2015

      Hi Melissa

      No it is important not to exceed the daily limits for each phase as oat bran is a high carb food.

      Kind regards


  • Julie on August 9, 2015

    Can I eat oat bran at night in the attack phase? Don’t want to mess ups my first day


    • Amber on August 10, 2015

      Hi Julie

      There is no reason not to eat your oat bran at night. Have it when it is going to suit you the best.

      Kind regards


  • rakie on August 6, 2015

    Hi Amber, after reading the web site i realized in order for the diet to work properly i needed to eat 1.5 tablespoons of oat bran a day, please correct me if im wrong. well the oat bran i purchased is Hodgson Mill wheat bran, im not sure if oat bran and wheat bran are the same. i had a hard time finding anything labeled oat bran, if this is wrong is it possible for you to tell me which oat bran brand to get and i could possibly order it online, also what should i do with the wheat bran? can i still use it at all?

    • Amber on August 6, 2015

      Hi Rakie

      Oat bran and wheat bran are not the same. Oat bran has been shown to have some very beneficial health benefits and this is why Pierre Dukan included this food in his diet.

      Oat bran can be purchased online and Hodgson Mill also sell oat bran

      Hodgson Mill Oat Bran, Hot Cereal, 16-Ounce (Pack of 12)

      As do Bob’s Red Mill
      Bob’s Red Mill Organic Oat Bran Hot Cereal, 18-Ounce Bags (Pack of 4)

      The wheat bran can be used in addition to the oat bran to help combat constipation but you should not have more that 1 tablespoon of wheat bran each day.

      Best wishes

      Oat bran can be purchased at Kroger in the health food section. If you have a Kroger. That’s where I found it.
