The Stabilisation Phase of the Dukan Diet Explained

The Stabilisation Phase of the Dukan Diet is the fourth and last phase which you will follow for the rest of your life to maintain your ideal weight. It is probably the most difficult phase to stick to as many people lose weight successfully a much smaller number manages to keep the weight off for good.

In this phase apart from one Pure Protein (PP) day each week, which is usually recommended to be Thursday, there are no foods or drinks that are off limits to you but if you return to the unhealthy lifestyle and eating habits that you had before starting the Dukan Diet you are unlikely to be successful and you weight will start to climb back up again.

It is a good idea at least at first to base your new eating plan around the rules of the Consolidation phase and just add in an extra piece of fruit each day or an extra portion of high carb starchy foods each week or use little oil or fat in your cooking.

Although there is nothing off limits you are expected to continue to eat 3 tablespoons of oat bran and drink 2 liters of water each day. You are also expected to continue exercising for at least 20 minutes each day.

If you start to put on weight again you can add in an additional PP day each week or increase the amount of exercise you are undertaking each day until you are back to your target weight.

    Hi Amber

    Great site thanks

    Is this a good muesli to have on stabilisation phase as I used to eat it before diet

      Hi Gary

      In Stablisation you have total flexibility over what you eat on every day except Dukan Thursday but you do need to eat sensibly. Having had a look at the nutritional information there is no reason for you not to enjoy this muesli.

      Best wishes

    Hi Amber. Epic fail!!!! Need help to get back on track.
    After being quite poorly on and off for months with pleurisy I have put on 7 lb. I really struggle with protein days and found lack of salt/sugars I have bad dizzy spells (really low blood pressure most of the time).
    Do I have to start all over again? What’s the best way to get back on track without these horrible BP crashes. (Doc say it’s ok just have to keep eye on it. No meds)
    I should also mention I’m on the go all the time with two autistic boys 4 and 3, trying to work and very little sleep!! Meals are really hard as the boys shun most foods and I end up cooking 3/4 different meals! Really need some ideas that are easy to keep me in line with some sweet treats to keep me on track as when Bo crashes it’s straight for a biscuit instant fix!!

      Hi Nikki

      Not being able to follow the diet because you’ve been ill is not an epic fail. The Dukan is quite restrictive nutritionally so you need to be in good health to follow it.

      I’d recommend using your oat bran to make muffins for your weaker moments but I’d also have plenty of yogurt and sugar free jello (US)/jelly (UK) to hand as well. Sugar free gum is also another lifesaver.

      In view of the demands of your sons and your low BP I’d also suggest trying a Cruise Phase of just PV days to keep you on a regular eating pattern.

      Look through the foods that you can eat and see if there is anything that you could cook that all of you can eat, if not I’d planned ahead and try to bulk cook some meals for you that you can freeze.

      Take care.

    Hello Amber,

    I have successfully come through stabilisation and am now living in a Dukan way to maintain my hard work. Looking for new ways to continue with my oat bran I have started to make my own muesli with rolled oats and oat bran. I know that raisins are not as healthy as I had once thought and so mix in goji berries and sunflowers seeds. Can you advise me as to whether dried pineapple or papaya would be reasonable for a little bit of added sweetness. I have read some good things about papaya and I would choose an unsweetened variety.

      Hi Sophie

      It is lovely to hear from you again.

      Living in a Dukan way should hopefully allow you to enjoy any food in sensible amounts of course so if you want to have a few raisins you should have them. If you put too many foods off limits your diet will become dull and uninteresting and difficult to maintain. Papaya is a great choice as it is high in antioxidants but whatever dried fruit you choose chop it up into small pieces so that it goes further.

      Take care

        Hello Amber,
        Could you please do a couple of menu plans for PP Thursdays, I am concerned that I am not meeting the stricter requirements. When I do a plan the meals are very plain and frankly not a delight. Want to make the PP Thursdays a doable part of the week and not a chore. Any ideas greatly received.
        On another topic I have found that my IBS is very well controlled since embarking on the Dukan, that wheat and I are not great friends and that gluten can also cause almost immediate discomfort. I am seeing my GP next week to see about a blood test to see if I am in fact suffering from cealiacs disease.I am very pleased to say that it is possible to get gluten free oats.

          Hi Sophie

          I’ve just put this post together for you. I hope you’ll find it helpful.

          I’m so pleased that your IBS is still so much better.

          The blood test doesn’t always pick up a gluten problem so I’d listen to your body rather than rely on a test. The advantage is that if your can get diagnosed you will be able to get some foods on prescription.

          Take care.
