We love reviewing wildly popular eating plans such as the Danish Diet. We looked closely at the ingredients, side effects, and clinical research. Furthermore, we examined hundreds of user reviews to get their side of the story. At this point, we compiled the facts to give you the info you need.

What is the Danish Diet?

First off, the Danish Diet is also known as the Royal Danish Hospital and Copenhagen plans. This weight-loss method basically involves a strict 13-day menu. Within this time, you can potentially drop up to 22 pounds, according to the literature provided. However, you are expected to avoid alcohol, heavy sugars, grains and even fruits. You can intake lettuce, lean beef, coffee, eggs and spinach. You will reduce your daily caloric intake to about 600, which is not enough to provide all of the nutrition you need, according to research.

It’s unclear when the Danish Diet first emerged, but both women and men can try this plan. Foods that are high in fat and cholesterol are cut out and you must drink plenty of water daily, but read on…

Food Restrictions – “What Will I Eat?”

The first problem dieters may face with the Danish Diet ingredients is that there are too few foods allowed on the plan. According to our Research Editor, “Some people will not be able to handle the strict menu. After all, you can basically just drink tea, coffee and water for liquids. Not to mention, the daily calorie intake is so low, some people may experience side hunger and a decrease in energy.”

One dieter stated, “Too many food restrictions…can’t have ham, no alcohol, no sugar at all!”

“This diet plan is not good for vegans! The protein sources are wrong!,” said another user.

Results – “None to Speak Of”

We could not find any real clinical studies to support the Danish Diet and that’s something that’s not lost on dieters. One said, “This diet did not help me with weight-loss at all. Just made me real frustrated.”

Another person commented, “Not a good diet plan for me! No thanks.”

Our research has revealed that if there is a certain aspect of a diet program that is especially annoying or concerning (a painful/difficult exercise routine, lack of real research, too many food restrictions) the likelihood of lasting success is minimal. Therefore if the Danish Diet is too strict, dieters may switch the plan out for a supplement that’s clinically tested.

The Science – “Any Real Proof?”

Here at DietSpotlight, we like to see some published clinical research that supports the diet program or pill we’re examining. However, we did not locate any proof to back the Danish Diet method. While most people already know that reducing your daily calorie intake will lead to weight-loss, this is not unique to this option. There’s also no connection with the plan and an increase in metabolism or fat loss. That’s what the dieter is really looking for, right?

The Bottom Line – Does the Danish Diet Work?

Well now, does this one offer anything new for dieters? It’s not a secret that reducing your daily caloric intake helps you lose weight. Most people are aware of this. Basically, this is what the Danish Diet relies on. However, when you consider the restriction with this plan, we have reservations about giving the green light. Plus, this is not good for the long run because it only lasts for 13 days. So, you’re very likely to gain once you go back to a regular diet.

If you’d like to see more drastic weight-loss results and a trimmer figure, we encourage you to try out a diet program that supplies enough calories and nutrition to keep you healthy, while helping you lose weight. You can pair that plan with a clinically tested supplement with solid customer support.

Among the best products we’ve seen this year is our product called Leptigen. The formula is a blend of four ingredients, all clinically-tested with results often found in journals such as Obesity and the Journal of Medicine.

Also, we’re so confident that you’ll love our supplement, that we’re offering a Special Trial Offer, which is a great sign.

Previous Danish Diet Review (Updated September 23, 2014):

What You Should Know About Danish Diet

The Danish Diet claims to help users lose ten to twenty pounds in just thirteen days. They do state that the amount of weight lost will depend on the individual and how much weight the individuals body needs to lose. The Danish Diet must be followed precisely or it probably will not work and this diet is extremely strict. The diet plan was designed to help increase the metabolism and they claim that this boost in metabolism can last up to two years regardless of how the user eats once they are done with the diet.

Product Features of Danish Diet

The Danish Diet helps users plan their meals for breakfast, lunch and dinner. Users can have absolutely no snacks and must drink plenty of water. Some days users are able to eat a portion of beef steak with a salad and other days users must only have a glass of water as one of their meals. There will be days where users are eating three meals and then there will be days where users are eating a meal and then two liquid meals consisting of coffee or tea and water. This strict diet is supposed to help users eat foods that burn calories upon ingestion as well as some extra calories.

Advantages of Danish Diet

  • The Danish Diet's meal plan is posted online in its entirety.
  • The actual diet is free users will have to pay for their groceries though.

Disadvantages of Danish Diet

  • The creator of the Danish Diet is not disclosed.
  • No research or clinical studies have been conducted on this diet.
  • The Danish Diet requires users to adhere to strict guidelines and lifestyle changes.
  • Absolutely no substitutions or compromises can be made with this diet.
  • The Danish Diet is not a good match for vegetarians and vegans.
  • This is only a short-term diet.
  • The typical breakfast on the Danish Diet is a simple cup of tea or coffee with one sugar cube.
  • The website contains several typos and errors.


The Danish Diet doesn't really stand out from the rest of the weight loss and weight management diet programs today. The Danish Diet may not be for everyone because there are no supplements included with any proven fat burners or appetite suppressants in them so those seeking a diet in which supplements are used that have the ability to suppress the appetite and burn fat may want to research other programs with products that are intended for appetite suppression and fat burning. Those seeking weight loss should also develop a healthy diet and exercise program that works for them because then they are more likely to stick to it. Users will need to assess their health and fitness goals and decide if using the Danish Diet is right for them.

I’m on day 12 and I took medlemon for flu,I’m worried that I ruined the diet already,can I continue with the diet or give up

Cameron (Editor)

No, just pretend you hadn’t, your progress will forgive you, if you do. Breaks or a brief lapse in a diet often throws people off, sometimes discouraging them entirely. Continue as directed by the diet.


I did this diet about 8 years ago (2010) and lost about 16lb. I am just starting day 5 and lost 5lb in the first 3 days but seem to have come to a hault at the moment! I’m hoping the weight starts to come off again.
I think it’s all about will power. I don’t have as much energy as have only been to the gym once this week.

Good luck to all who are trying it. It’s hard but is effective ☺


How long ago did you start it? did you actually lose more weight after you hit a slump?


I’m just loving it, though sometimes I lost my appetite while looking at menu but my energy level are superb till now and I’m going to gym as well 4 days in a week with this diet.. I lost already 4kgs. It really motivates when u r losing day in n day out. All the best.. ????


hey Adam and anyone else reading this and has actually done it.
Question 1: i’m on day 4 today but last night i baked a cake for a friend and took a TINY bite to check for taste and a swallowed it (Oh no..sad i hear you say), do i not bother continuing or should i just keep going with this diet?
Question 2: is ok to swap days?

Hi Tanya! For detailed product and usage instructions, please refer to the Danish Diet official website for more information.


I used this diet about 2 years ago and lost 7 kg in this 13 day period. I have not lost nearly as much on any other diet. I returned to my normal diet and gained nothing back. This diet worked for me.


is it necessary to have lettuce and celery? can I just leave it without supplementing i

Your Name Ezy

Hi Ezy! Please make sure to consult with your physician before starting a new weight-loss program or product

Devon (Editor)

On average it takes around a month to see results and sometimes longer, depending on your goals. over a month for desired results. Be sure to include regular exercise in your regimen.


am on day 4 and am feeling great.when am hungry i drink lots of water .


I finished this diet last Sunday. I lost 5.5 kg and I feel great. It was a struggle, but 13 days aren’t forever and results show.


This diet is very unhealthy too many eggs there is not a balanced diet here. Sensible eating is the only diet. All the green and everything colorful and you will loose weight. Stay away fro the Danish diet. You will only lose and gain weight in an up and down cycle.
