What is the Danish Diet?

According to a study performed by Aarhus University, the Danish diet also is known as The Copenhagen hospital diet. It is an extreme diet set up to ensure a rapid weight loss of approximately 22 pounds in just under two weeks. The Danish diet idea was to help people lose weight as quickly as possible, especially to get them ready for an operation if they were obese.

For this reason, it was also known as the Danish hospital diet. It can be dangerous to operate on people who are very overweight, so the diet was devised for quick weight loss. Today we know that extreme dieting is extremely dangerous. Although the Danish Diet plan did include healthy foods, it was a very hectic way to lose weight.

The actual Danish Diet meal plan does get sold online via their website. Today, it is pretty similar to the Banting diet, which is all about high protein and no carbs and no sugar. The Danish Diet is a tough diet to follow, and it did result in quick weight loss, especially if you look at the Danish diet before and after photographs.

Doctors today would be doubtful to recommend the Danish diet or suggest you follow a Danish diet menu because of the extremity. It is sometimes necessary to lose weight very quickly, but extreme diets are thought to be dangerous, and this is what some of the research says about this kind of diet:

  • NutrientsThe Danish Diet is often lacking in iodine and vitamin D, meaning it may not be a good meal plan to follow long term.
  • Journal of Proteome Research: When compared to the New Nordic Diet, the average Danish Diet is lacking in long-term weight-loss effects.
  • The British Journal of NutritionGradual weight loss may be better for weight loss maintenance when compared to rapid weight loss methods.

Do Extreme Diets Work?

Yes, people lose weight quickly on an extreme diet like the Danish diet, but it is tough to keep the weight off. Almost everyone who does a strict diet will put the weight back on immediately.

For that reason, no extreme diet is recommended unless the person is obese and needs to lose weight for an operation that is deemed necessary. The 13-day Danish diet program worked, which is why there is so much written about it, but…is it healthy? Medical doctors would say absolutely not.

How Did the Danish Diet Start?

It started in Copenhagen a few decades ago, and although it is unclear how or where it was first started, or who devised it, it became known as the Danish diet hospital plan. Therefore, it is thought that it was started perhaps by a medical doctor, though today, medical doctors know much better to help a patient lose weight. Of course, anyone could have started it. It is all about extreme weight loss, and it is essential to be in good shape, but it is vital to lose that weight in a healthy and balanced way. The Danish diet is sold for $14 in 2011.

We know that fad diets like The Danish Diet can be dangerous, as the menu included lean beef, eggs, coffee, and lettuce. You can look online to see what else was included, but it was all about no sugar, no carbohydrates, and no fat. Too much protein can be bad for you, your cholesterol, and your heart, according to research in ISRN Nutrition, but the 13-day Danish diet was all about high protein, no fat, no sugar, no carbs, and ensured you would lose 22 pounds in 13 days. It went as far as saying no chewing gum and was exceptionally rigid.

danish diet background

Is the Danish Diet Considered to be a Starvation Diet?

No, because people can still eat on the Danish diet, the amount of food was well monitored. Calories per day were 600, which is not enough to give anyone the right minerals, nutrients, and vitamins, let alone enough protein or good fats. Today, we know that there are good fats that must be included in a diet to help weight loss, according to the Nutrition Journal and Cochrane Library.

It’s also known as The Copenhagen Diet and the Royal Danish Hospital Diet.


Danish Diet Claims

The Danish Diet or the Royal Danish diet claims that the dieter will lose 22 pounds in 13 days. They would give an obvious food plan, mainly including lean beef, eggs, coffee, and lettuce or spinach. We imagine it included any leafy green vegetables.

This is an extreme diet, and so anyone who does it will lose weight. The claims then of extreme weight loss in a short period are true. But the health benefits are minimal unless the person is obese. Even then, an extreme diet is dangerous, and so while the Danish diet comes with a strict plan and menu, the risks are incredibly high.

Does It Work?

The Danish diet before and after photographs will show that the weight loss program works, but if you are having thoughts of doing this diet, only do it under the intense supervision of a doctor or dietician.

You should never do such extreme eating unless you are told to by a doctor. The Danish diet side effects are extreme too. Eating so little means that your body would have no energy, your sugar levels would fly all over the place, and the Danish diet results might work short-term, but cannot work long-term.

So while you will lose weight when you follow a rigorous dieting regimen such as this one, and The Danish Diet is far beyond extreme, you will put the weight back on again, and you will feel worse than when you started.


Danish Diet Ingredients

There are far too many restrictions on the Danish Diet menu, which is comprised of minimal ingredients. The idea behind the menu is that you hardly eat anything at all. To have just 600 calories a day is insane! A little coffee, a little tea, some lean meat, some lettuce–insane indeed. Lettuce hardly contains any calories, and it doesn’t exactly fill you up or give you energy. If you are a vegetarian, then you must stick with only green leafy vegetables, tea, and coffee.

Also, the idea of having coffee on a diet is rather strange, as it is a stimulant and so will give you the jitters and the shakes, especially when you are drinking a lot of it without food. It may well burn some fat, but the Danish diet’s copious side effects make that idea of fat loss not very desirable.

Before and after photographs are proof of fat loss, albeit not exactly proof of safe weight loss, and they don’t show all the weight that the dieter would have put back on when they started eating normally again.

Here is the Danish Diet Shopping List:

  • Lean Meat
  • Lettuce or spinach
  • Eggs
  • Coffee or tea

The Danish diet is not the only insane and extreme weight loss diet programme on the market: there are many. Each one is as dangerous as the next. We know that to lose weight, you need to do it slowly, carefully, and still have a wide range of foods that will give you the protein, dairy, vitamins, nutrients, and minerals your body needs to work well together.

The typical Danish diet would be an egg for breakfast, lean meat, and lettuce for supper, and lean meat, and lettuce for dinner, with plenty of coffee and lots of water in between. This can be incredibly boring, as well as straight-up exhausting! Sure, you will lose weight, but your muscles will start to disintegrate, and your brain will experience a decline in functionality.

As you go further into the diet, the ingredients do change. You start off with the lettuce, eggs, and lean meat, and gradually introduce other vegetables, some toast, and fish.

danish diet ingredient

Danish diet ingredients therefore include:

  • Lettuce, spinach, or any green leafy vegetables
  • Lean Meat
  • Coffee
  • Eggs

And as time goes on:

  • Whitefish
  • Carrots
  • Tomatoes
  • Beans

It is an inadequate diet!

Benefits & Results

Danish Diet Benefits and Results

The Danish Diet says that if you consume 600 calories a day, you will lose weight, although that’s mainly because there is almost no food going into your body. So while the Danish diet results may well be good initially, the long-term effects are not worth it. You can land up having kidney problems, bowel issues, and a wide range of other health conditions associated with extreme dieting.

Won’t I feel great if I do the Danish Diet?

Truthfully, when you starve yourself due to little food consumption, you feel hungry, weak, and irritable. That begs the question: is extreme dieting worth it?

Should I exercise at the same time as doing the Danish Diet?

If you do The Danish diet, you won’t have the energy to exercise as well. Any decent weight loss comes from a healthy eating program and a good exercise regime. If you exercise while following the Danish diet menu, you will probably faint or pass out or get ill. Your body just won’t have the energy to do anything!

Are the results of the Danish Diet quick?

Yes, the results from the Danish diet are quick because, basically, you are starving yourself. Don’t ever starve yourself! Diet and weight loss need to be done sensibly, and weight loss should be slow. The slower the weight loss, the more it will stay off permanently. When you do an extreme diet, such as the Danish diet, you will lose weight quickly, but you will put it on just as quickly, and you will probably put on more weight. Instead, don’t go for quick weight loss–go for steady weight loss.

Details on Danish Diet

We have spoken about how the Danish diet has a rigorous eating plan, and how the Danish diet menu consists only of lean meat, eggs, lettuce or leafy greens, and coffee. It is an unbalanced diet and an extreme diet, and while you will lose weight quickly, you will never keep the weight off. Plus, you will more than likely develop health problems from the diet. You will feel weak and irritable, you will not have any strength, and you won’t be thinking clearly either.

The details of the Danish diet menu can be found online. It is an unhealthy menu in that you are severely starving your body of all the good foods that it needs for optimal function. Instead, you should consume nutrient-rich foods, follow a healthy eating plan, consult a dietician, and take a weight-loss supplement that is recommended and well-reputable. The 13-day Danish diet may assure you of weight loss, and you will lose weight if you follow it, but such results are not long-term and will be at the cost of your overall well-being. Plus, the total damage you can do to your body is just not worth it. The Danish diet results can be found online, where you can additionally read reviews, and you will see that people lost weight quickly, but almost everyone says they put the weight back on immediately after.

What Do Dietitians Think of the Danish Diet?

Take any Danish diet reviews online with a pinch of salt. No nutritionist or dietician will tell you that you need less than 600 calories a day; rather, they would tell you about the dangers of the 13-day Danish diet. Diet and weight loss are something to be taken seriously. Eat well, drink lots of water, exercise well, cut out the sugars and carbohydrates, and diet sensibly for weight loss that stays off.


How to Follow the Danish Diet

You get the 13-day Danish Diet, and you follow, day by day, the Danish Diet menu and Danish Diet meal plan. The menu is incredibly limited. You have your three meals per day, breakfast, lunch, and dinner, with coffee and a lot of water in between. The Danish diet does not include any weight loss supplement. Still, it is an extreme diet where the dieter will be hungry, miserable, irritable, and probably suffer from a severe lack of energy and also headaches and nausea. If you do the Danish diet, you should do it under the strict supervision of a doctor or dietician.

Even if you need or desire to lose a lot of weight, never do any extreme dieting, unless you have been told by a healthcare professional, according to the Indian Journal of Medical Research. Instead, eat a well-balanced menu every single day that includes protein, fruit and vegetables, good fats, and plenty of leafy greens. The Danish Diet has so many good reviews online. But, if someone recommends The Danish diet, do your research first. Read the Danish diet reviews and do not be mislead by the Danish diet before and after pics.

They show you immediately afterward when the person will have lost weight, but they do not show you the pics a week or so later when the person has picked up all the weight, plus more. The Danish diet or any extreme diet really should only be done if you are obese, and a doctor has told you to do it and then monitors you while you do it.
Remember, not everyone has reviewed the Danish Diet honestly, as they have not spoken about their health issues or that they put all the weight back on.

Side Effects

Potential Danish Diet Side Effects

Any extreme dieting is going to cause side effects, according to the Annual Review of Public Health and Clinical Nutrition ESPEN. With the Danish Diet, the side effects can be life-lasting or even life-threatening. A strict diet is not good for the kidneys or the bowels, and starvation can result in brain damage too. To mention here are some of the side effects of the Danish diet:

  • Lack of energy
  • Stress
  • Headaches
  • Nervousness
  • Nausea
  • Muscle aches and pains
  • Deficiencies
  • Hunger
  • Illness
  • Kidney problems
  • Bowel problems
  • Liver problems
  • General malaise

Product Warnings

Danish Diet Product Warnings

Because the Danish diet is not exactly a product, there are no product warnings. However, all the warnings are those that we have given you above. Extreme diets are dangerous. Strict diets are not good for your health. In fact, nobody should do an extreme diet, as they can result in overall health problems, long-term health problems, and eating disorders.

No baby or child should EVER do an extreme diet, nor should they divulge in the Danish diet menu or Danish diet eating plan. Everyone needs to have a balanced diet with the right mix of protein, good fats, dairy, minerals, vitamins, and nutrients, as well as participate in a steady exercise regimen.


If you are going to do an extreme diet, make sure you consult a dietician or nutritionist and do it under their supervision all the time. But we feel the product warning should be not to do any extreme dieting and do not follow the Danish Diet meal plan.

Keep in mind that there’s no scientific data to support the claims or safety of this product.

Any Danish Diet Lawsuits?

There would be nobody to sue with The Danish Diet as there is no manufacturer as such. We have, therefore, not found any lawsuits. If your dietician put you on a Danish Diet meal plan for any reason, you could perhaps have an issue with them if things go wrong.

Danish Diet Alternatives

The best alternative to The Danish Diet and the best way to avoid its side effects would be never to participate in it or any kind of extreme dieting. You can follow a healthy eating plan, drink lots of water, perform regular exercise and, if you are overweight, take a weight loss supplement that is not dangerous but instead natural and will help you get towards healthy eating and a new way of life. These are some of the supplements or weight loss supplements that people do take with a healthy eating program to lose weight.

Bottom Line

The Bottom Line on the Danish Diet

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 this plan’s restriction, 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 weight 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 Noom. 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 Noom, that we’re offering a free trial offer, which is a great sign.

Does the Danish Diet work?

Are there any risks associated with the Danish Diet?

It is based on a Mediterranean-style diet and emphasizes consumption of fresh fruit and vegetables, whole grains, lean proteins, and healthy fats.

Research has shown that following this type of diet can help reduce risk factors for certain diseases such as heart disease and diabetes.

Does the Danish Diet come with a guarantee?

Consuming a small amount of calories on the Danish Diet is a way to drop the pounds, but consider a supplement like Dietspotlight Burn, which contains some clinically-tested ingredients, shown to work and doesn’t require strict food guidelines.
