Copenhagen Diet : Rigorous 13 Day Diet Plan For Weight Loss and Detox

What is Copenhagen Diet?

Copenhagen Diet aka Royal Danish Hospital Diet, Swedish diet, is a 13 Day Diet Plan, consisting of foods that are high in protein and low in fat. It is also famous by the phrase “13 Day Diet On The Way To Paradise”. It is one of the buzzing diets these days to slim down over a short period of time.

People are using it to lose weight fast for an upcoming event such as a wedding or a similar ceremony.

But does it work? More importantly, is it safe?

Let’s dig deeper.

To sum it up, Copenhagen Diet Boils down to be:

– Very Rigorous
– Fixed and Specific menu, which you cannot modify.
– Fastest results giving diet

Yes, it indeed is very rigorous and is not everyone’s cup of tea. But, if you are determined enough, you can get through this diet plan with some fantastic results.
Such as losing 15 to 20 pounds.

How many meals are allowed in Copenhagen diet?

You can have a morning coffee/tea and 2 meals a day, lunch and dinner. Most people reported tremendous results by replacing their coffee/tea with some herbal detox tea or green coffee. 

For tea lovers I recommend:

Gentle Detox Tea by Total Tea

Because, I am using it for 5 years. It has helped me in many ways, be it constipation, reducing inflammation or weight loss. 

And for those who love coffee I recommend to use any good quality organic green coffee. 

And if you love green tea lover, then I suggest you to go for Matcha Green Tea Type.

Because, Matcha is the best of all when it comes to weight loss.  The one I use is:

Jade Leaf Matcha Green Tea Powder 

I use Jade Leaf because,  it is best quality for the price,  comes directly from Japan and is vegan and gluten free. I came to know about it in a meditation retreat in Oregon. Since then, I gave up the ones I was using earlier. 

How many calories can I Consume in Copenhagen Diet?

You can take 900 calories a day. If your calorie intake goes above that. You are not on Copenhagen Diet. Use WebMD Food calculator to keep track of calories you are taking in.

Journaling your intakes is also a good idea.

Here is how can you replace meats mentioned in this article:

  1. Fish: Tempeh(It is very similar to tofu)
  2. Chicken: Jackfruit, Cauliflower, Eggplant
  3. Beef: Beans (These contain 8 Grams for protein and 8 grams of dietary fiber each half a cup)

By the time you finish this diet, it is very likely that you will lose at least 15 to 20 pounds, depending on your body type and amount of fat that your body has.

Apart from weight loss, here are the other effects it will have on your body:

It speeds up your Metabolism

Foods you’d be consuming in this 13-day diet plan will increase your metabolic rate. Eggs, beef, and chicken are very rich in protein and demand more energy to digest. This is because thermic effect these foods have. Thermic effect is expenditure rate at which your body spends energy to digest food.

  1. hey, can I take appetite suppressants with this diet and will I continue to lose weight afterwards?

    Is Copenhagen diet the same as 13 days metabolism diet.

    I have just finished the metabolism diet and I don’t think I have lost any weight.

    • Hi There,
      It is not recommended to take appetite suppressants along with this diet. Because they come with many unwanted side-effects. Yes, Copenhagen diet is the same as metabolism diet. Can you please elaborate a bit more on how you went about it?



    • Hi Aishu,

      Here is how can you replace meats mentioned in this article:

      Fish = Tempeh(It is very similar to tofu)
      Chicken = Jackfruit, Cauliflower, Eggplant
      Beef = Beans (These contain 8 Grams for protein and 8 grams of fiber each half a cup)
      Pork = Jackfruit



  2. Hi there
    How much iceberg lettuce and celery i could eat.
    Also if i not have spinach on day one will cause any issue?
    Do I have stop my diet or its okay to continue?
    Thanks for your help.

    • Hi Julia,

      You can have 150 to 200gm off lettuce and celery combined. On your spinach question, according to my reference for this information, Copenhagen diet has very strict rules. So, you should not change anything. You should not follow this diet more than 13 days in any case.



    • We advice that way as a safety measure. But you can always consult a doctor and ask them if your present health can handle that kind of a diet.

    • Hi There,

      Copenhagen diet should not be continued for more than 13 days because losing weight too fast can lead to other complications, such as nutrition deficiencies, slow metabolism and gallstones. Also, weight that you lose too fast backfires even faster than it took to lose it.

    • Hi Miky,
      Yes you can replace spinach with lettuce.
      Yes you can add olive oil, lemon juice and salt pepper.

      Just keep your calorie intake below or up to 900.

  3. I’m thinking about starting this diet few questions, can I replace celery and yogurt with anything? (not a fan) last question when it says ham, what kind of ham, how many ounces? There’s spiral sliced, deli meat…
