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,

    i sticked to the Dukan diet for 2 months and half and I’ve lost 8 KG, however, i gained some weight since i stopped my diet.
    Now i’m redoing it again but am not getting any results at all.. i am so frustrated that i started to think i will never lose weight anymore.. could the dukan diet stopped working for me ??

      Hi Yara

      It sounds as it you didn’t follow the diet through all of the stages as you never stop following the Dukan as Stabilisation is a phase that is followed for life. You just need to be patient and follow the diet as intended and everything will work out.

      Kind regards

    Hi Amber,

    I started the dukan two weeks ago. I did the attack for 6 days and I lost around 0.5 kg. I was disappointed with this as I expected to lose quite a lot more. Since then having been on the cruise for 8 days, I have lost nothing. I am really confused, completely de motivated and upset. I have been having daily oat bran so I don’t think its constipation. Perhaps its the salt I add to my food but that can’t be the reason for an 8 day stagnation can it? I also pretty much only eat white protein or at a push tuna but thats it. I’m doing 20 minute walk a day. I have added in an extra PP day, but nothings shifting. I am pretty sure I am eating over 1200 calories a day. I can’t think what it is. so tempted to give up.

    Thanks, Grace

      Hi Gracie

      If you are following the diet correctly to lose just .5 kg after 2 weeks is not what would be expected. If you are not constipated or suffering from water retention I would suggest seeing your doctor for a check up just to make sure that there is no underlying medical condition preventing you losing weight and based on your results I would recommend trying a different weight loss program as the Dukan method does not appear to work for you.

      Kind regards

    Hi Amber,
    Your website is amazing, thank you for your support!
    I started this diet 7 days ago, I start the cruise phase tomorrow.
    Within the first 3 days I lost 7.1lbs, my starting weight was 185lbs, I got down to 178lbs, now on the 7th day I’m back up to 182lbs! This is extremely frustrating as I have been following this diet correctly! I also do 45min of intense exercise every other day.
    Any suggestions, I’m willing to stick this out but need to make some changes I think. Thanks!

      Hi Mimi

      A 4 pound gain in one day is likely to be due to water retention with perhaps a little constipation as well so try to stay strong and stick with the Dukan and this blip should sort itself out.

      Bet wishes
