How Long Should the Attack Phase of the Dukan Diet Last?

The Attack Phase is the first phase of the Dukan Diet and it provides a great kick start to your weight loss program. The length of the Attack Phase is variable and it lasts between 1 and 10 days and how long you need to stay on the Attack Phase depends upon how much weight you want to lose and how quickly. The best way to work out the length of Attack Phase that you need to use is to visit one of Dr Dukan’s official Dukan Diet sites and on the right hand side of the home page you will find a tool that will calculate your true weight.  When you have answered the questions you will be presented with a calculation like the one below. This tool also calculates your true target weight and gives you a good idea how long it will take you to lose those extra pounds and how long you will need to take to consolidate your weight loss before moving to Stablisation.


 

  If you don’t want to use Dr Dukan’s official tool you can use the information to give you a rough guide.

    • Less than 10 pounds to lose – a one day Attack Phase.
    • Between 10 and 20 pounds to lose – a three day Attack Phase.
    • Between 20 and 40 pounds to lose – a five day Attack Phase.
    • Over 40 pounds to lose – a seven day Attack Phase is  acceptable.  A 10 day Attack Phase is only used in very exceptional circumstances  and with the benefit of medical advice to support it.

    • The Attack Phase needs to be long enough to start your diet off with a great weight loss boost that will provide you with the momentum and encouragement to keep going, but it also can’t be too long  or your body adjusts to the lower levels of fuel that it is receiving and it reduces your metabolic rate, the rate at which your body burns calories, in order to preserve your fat reserves.  This of course is the last thing that anyone trying to lose weight wants!
      The limited range of foods eaten during the Attack Phase can make following this part of the diet quite difficult for some people, for a period of more than four or five days but also very importantly the Attack Phase foods do not provide your body with a nutritionally balanced diet or enough fiber.  Most people can of course cope with this short lived, short fall in nutrients without any adverse effects, but if you have any medical problems or underlying health conditions it is important that you consult your doctor before you start the Dukan Diet.  Even if you have no known health problems this is still very sound advice.

    Hi Amber,
    Thank you for this informative site !! My husband and I started the attack phase and stayed on it for 10 days before having any vegetables. The attack phase was very successful for us, however now that we are in the cruise phase we have each gained 2 pounds. I am concerned that we lowered our calorie intake for too long. I am concerned that we lowered our calorie intake for too long as you stated in the above post. Do you have any advice on how we can continue to move through the cruise phase successfully? I wish I had read your post a week ago!

      Hi Carin

      A bounce back or slow down in weight loss after a very effective Attack Phase is not unusual. Vegetables tend towards water retention while protein is diuretic so much of the weight gain is likely to be water. Stick with it and make sure that you are eating a reasonable level of calories you need a minimum of 1200 and your husband needs a minimum of 1500. Exercise is a good way of boosting your metabolism.

      Best wishes

    I have moved to cruise phase before the time i should be on attack i suppose to stay on attack 4 days and i only stayed for 2 days
    And i started cruise phase withPV
    Is that okay or i have to go back from day 1

    • Amber on November 26, 2015

      Hi Natalie

      If you want to have a shorter Attack Phase that is fine. THe Attack Phase is very restrictive and doesn’t suit everyone. It is better to move to Cruise than crash and burn on Attack.

      Kind regards
