I’ve Stopped Losing Weight on the Dukan Diet: What Can I Do?

If you’ve stopped losing weight the first thing to do is not panic, going through phases where you stop losing weight is not unusual and there can be lots of reasons for the stagnation in your weight loss.

The second thing to do is stick to the diet.  You don’t want to throw away all the good that you’ve done so far and continue to do staying on the diet.

The third thing to do is to make sure that you are doing everything you should following the Dukan Diet.  A quick checklist is:

  • Are you drinking 1 and 1/2 to 2 liters of water every day?
  • Are doing your compulsory daily exercise?
  • Are you eating the right foods?
  • Are you eating enough food?
  • Are you eating regular meals and not skipping meals?
  • Are you eating your daily serving of Oat Bran?
  • Are you having more than two servings of tolerated foods per day?

The next thing to do is to try to establish a reason for your weight loss plateau

  • Are you suffering from water retention due to your monthly period?
  • Have you eaten a lot of salty food that may have caused water retention?
  • Have you recently lapsed on the diet eating or drinking something that is not allowed?
  • Are you eating enough calories, for a long term weight loss plan you need to be eating in the region of 1,200 calories a day any less than this and you could find that your body lowers your metabolic rate and reduces the rate at which you burn calories?
  • Are you constipated?
  • Is it due to the vegetables that you’ve added to your diet?  Remember that pure protein acts as a diuretic and your body may try to hold onto the water from the vegetables to compensate.

You then need to work out your plan to tackle the problem.  This might be to do nothing as you think the problem will probably sort itself out or it might be to take some additional oat bran to help your constipation.  But there are also some things that you can do to jolt your body back into weight loss mode if needed these are to

  • Increase your daily exercising to 60 minutes per day.
  • Reduce your tolerated items to one or none each day.
  • Reduce your consumption of dairy products as these are high in carbohydrates due to the naturally occurring sugars.
  • Ask your doctor to recommend a vegetable based diuretic.
  • Try a White Day PP day.
  • Add an extra PP day into your Cruise Phase rhythm.

If these steps do not kick start your weight loss again and your weight loss continues to stagnate you must go to see your doctor as it might be that your difficulty in losing weight is due to health problems such as a thyroid problem.

    Hi Amber,

    Sorry, I have been reading the comments here and not too quite sure about what to do when we get to a stagnation period with our weight loss. I have been on the diet since Feb 1st and have lost around 21 lbs however the weight loss slowed down and now it has stopped for the last 10 days or so (and I still have 31 lbs to lose!) So should I not do the attack phase for 2-3 days to kick start the weight loss again? I vaguely remember reading something like Dr. Dukan advising this to his patients?

      Hi April

      I don’t recommend repeating the Attack Phase as too many people think it is the cure for everything and it is a very restrictive way of eating. Just be strict with yourself on Cruise and you should be fine and you will still be getting the extra nutrients that the vegetables provide.

      Best wishes

        Hi Amber,

        Thanks very much for the advice. Will do so. One more thing which has been reaaallllyy bugging my mind: I will be going on vacation for three weeks on June 25, and there is no way I can stick to the diet while I am there as I will be going back to my home country, and I do it only once a year – and I miss the food so much! Plus, I will be out and about all the time which will make things harder for me. I have been on the diet since Feb 1st, and if everything goes as planned, I will probably have 4-5 kgs more to lose just when I am going. I have never ever cheated, and been very good. But, I will have to give a break when I am close to my goal. So, what do you think I should do when I get back after three weeks? Should I then start the diet from the beginning, as I am doing it for the first time? Like, an attack phase for like 5 days or so and then the cruise? Or should I just start the cruise phase again after 1 day of pp? Would that really work? This is very important for me, so I am looking forward to your reply!

        Best regards,

          Hi April

          Enjoy your holiday but try not to have a total blowout. If you have a heavy day try to cut back the next.

          When you get back just start Cruise again with a PP day. Everything will be fine.

          Best wishes

    Hi Amber many thanks for your response. I am still gaining one day stabilising or losing a little the next. Still only just 3 kg in total, but I will persevere.

  • Laureen Pipkin on April 10, 2015

    I previously lost 16.5 kg on the Dukan and have gained 6 of it back after 3 years. This time I am finding it a lot more difficult. I lost 2 kg on the Attack phase (10 days) and have been on the Cruise phase for 5 days with no weight loss. I am also taking a 10mg statin. Could this be interfering with the diet?
    Many thanks Amber.
    Your comments and suggestions are very welcome!

      Hi Laureen

      Weight gain is a possible side effect of taking statins but it isn’t that common.

      It is usually more difficult when you repeat the diet as you have less weight to lose and have probably altered your eating habits. It is really important for you to stick with it.

      Best wishes
