Dukan Diet FAQs – Can I Drink Diet Coke on Dukan Diet?

So you want to know whether you can drink Diet Coke,the most popular sugar-free soft drink in America, while you are following the Dukan Diet.  Well given the popularity of this almost calorie free drink it is not surprising that people want to know the answer to this question.

Yes, you can drink Diet Coke in all phases of the Dukan Diet, but what may surprise you is that although it has next to no calories, it is not a drink that you can have in unlimited quantities as the extract from the online Dukan chat of 26 November 2012 below shows, you are only allowed a maximum of three cans of diet coke each day.

colincrk12 : Hi, Can Diet Coke be used during the Attack phase?
sonja : Hi Colin and welcome to the chat! You can have three cans of Diet Coke per day during all of your diet! Enjoy!

But there is another important fact you need to know, the serving of diet soda has to have one calorie or less to meet Dr Dukan’s stringent rules.  This means that not all diet sodas are allowed and it does in fact also mean that not all the different types of Diet Coke are suitable.

Diet Coke has one calorie per 250 ml serving as does Caffeine free Diet Coke but Diet Coke with Cherry has 2.5 calories for the same quantity and Diet Coke with Citrus Zest having 3 calories.

If you are a fan of other diet sodas the following drinks also meet the one calorie a serving rule:

  • Coke Zero
  • Fresca Black Cherry Citrus
  • Fresca Original Citrus
  • Fresca Peach Citrus
  • Diet Pepsi
  • Caffeine free Diet Pepsi
  • Diet Pepsi Lime
  • Diet Pepsi Vanilla
  • Diet Pepsi Wild Cherry
  • Pepsi Max
  • Tropicana Twister Soda – Diet Orange
  • Diet Sierra Mist
  • Diet Sierra Mist Cranberry Splash
  • Diet Mug Cream Soda
  • Diet Mug Root Beer
  • Diet Mountain Dew
  • Caffeine Free Diet Mountain Dew
  • Diet Mountain Dew Code Red
Post a comment below to let me know of other drinks that can be added to the list.

I’m not sure how Dr Dukan arrived at the one calorie a serving rule but I do know that he introduced a limit to the number of these types of drinks to help reduce our cravings for sweet foods.

    Jus checking in case! Can I drink 7up free during the attack phase? Even if it’s allowed, will it slow down my progress? Starting day 1 today and want to make sure I start as I should continue. Thanks in advance.
