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 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?

      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

    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.

      Hi Zainab

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

      Kind regards

    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

    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.

    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

    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

    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?
