The Cruise Phase of the Dukan Diet Explained

The Cruise Phase is the second of the four stages of the Dukan Diet. It is also the second of the two weight loss stages. The Cruise Phase is the part of the Dukan diet where followers lose the remaining pounds needed to bring them to their target weight.

How long you will need to stay on this phase of the diet does of course depend upon just how much weight you have to lose. As a rough gauge you will lose about a pound for every three days spent cruising.

In this part of the diet you alternate a pure protein (PP) day as in the Attack phase with a protein and vegetable (PV) day. The high protein foods which can be eaten on PP days remain as in the Attack Phase and there are 28 permitted vegetables that can be added on PV days.

Whilst cruising you should usually follow a rhythm or pattern, this is the way in which you alternate the PP and PV days. When the diet was first published the recommended rhythm was 5 PV days followed by 5 PP days however many found this regime difficult to fit into their routines. The current recommended rhythm is 1 day PV followed by 1 day PP.

The 1 day PV/ 1 day PP rhythm does have some definite advantages. It allows you more variety and needs less willpower. 5 days of PP in one stretch is not an easy feat to repeat time and again. It also adds the additional fiber from the vegetables in a more evenly distributed way.

You could of course devise your own rhythm and say have PP only days on Mondays, Wednesdays and Fridays with PV days for the rest of the week. The PP days can equal but should never exceed the PV days and there should not be more than 5 consecutive PP days. If you adopt a personalised rhythm you may not lose weight so quickly but you may find it easier to maintain.

In this phase of the Diet you increase the daily amount of oat bran consumed to 2 tablespoons a day and up the amount of daily exercise to 30 minutes.

    What kind a sausage can I have and how much. I am on cruise phase. How much fat and carbs etc. ??

      Hi Christine

      Most sausages wouldn’t be suitable. You are looking for a 100% meat product with 5% fat content and minimal carbs.

      Best wishes
