Royal Danish Hospital Diet

A fad diet based on high protein and cholesterol.

Top Rated Diet Shakes of 2016
BACKGROUND Start the Diet Now Advertisement

The Royal Danish Hospital Diet is a strict diet promising unbelievable results. In some cases this diet has been referred to as the 13 Day Diet. This diet has been classified as a fad diet, which should send up a lot of warning signs right away. The diet claims that you can lose between 13 and 22 pounds in just 13 days. The Royal Danish Hospital Diet is done for exactly 13 days, so it would be more of a jumpstart for those that have a large amount of weight to lose. The program is very strict and many people find it difficult to stick with for the entire 13 days. Supposedly after the 13th day, you can return to eating “normal” and maintain the weight loss for two years. Although this diet is named after a reputable hospital, it has been proven that the hospital has no dealings with this diet. Similar to the so-called Mayo Clinic Diet from years ago, the Royal Danish Hospital has avidly condemned this program for its unhealthy nature.

Basically, the Royal Danish Hospital Diet is a hoax and not something that anyone should follow. This diet is dangerous and unbalanced. There is an excessive amount of protein consumed with this diet as well which can be harmful to the body. Lastly, the Royal Danish Hospital Diet is very high in cholesterol. There is a high amount of eggs consumed which amounts to double the recommended daily intake. There are some very strange rules involved with this diet as well.

Do You Know the Best Diet Shakes of 2016?

  • None to speak of
  • Diet is very strict
  • Classified as a fad diet
  • Name is deceiving; Royal Danish Hospital does not authorize this diet
  • Encourages eating high amounts of protein which can be harmful to health
  • Eliminates important foods like fruits and vegetables
  • Promises unrealistic weight loss results
  • Includes strict rules that are unnecessary
  • Encourages skipping meals

There are many restrictions involved with the Royal Danish Hospital Diet. This diet tells you to eat foods that are high in cholesterol and it is very protein heavy. It is important to note that you are only supposed to follow this diet for 13 days. There are claims made that you will lose between 13 and 22 pounds in this amount of time. Some of the strange instructions for this diet even suggest that having a cup of coffee for breakfast is sufficient fuel to get your body going. Chewing gum is not allowed and you can’t switch your coffee for tea. The diet must not be repeated except once every two years. If you successfully complete the 13 day cycle, this program is supposed to boost your metabolism and keep it raised for two to three years. If you stop in the middle of it, you cannot start again for six months. The menu is set for all 13 days of the program, and it’s apparent that this diet does focus on calorie restriction for the quick weight loss. Below is a menu from one day on the Royal Danish Hospital Diet:

  • Breakfast – 1 cup of coffee with 1 sugar cube
  • Lunch – 2 hard boiled eggs with spinach and one tomato
  • Dinner – 7 oz. steak with lettuce and lemon

There appears to be no exercise recommendation given with this diet. The severe calorie restriction will likely not allow enough energy for exercise. The diet’s short time frame may also contribute to the lack of exercise advice.


Fad diets pop up all the time and usually involve unrealistic instructions, strange eating habits and false hope for amazing results. The Royal Danish Hospital Diet fits all of those categories. This diet has been classified as a fad diet and also called dangerous by several reputable health experts. Losing weight takes hard work through the reduction of calories and an increase of activity or exercise. Diets like the Royal Danish Hospital Diet can actually lead you to have additional health problems rather than helping you lose weight.

It works for me. I tried some diets that have you consuming even less calories than this one and they were not producing nothing close to comparable results.
On this diet I lose typically 0.5 kg per day and rebound approximately 1 kg total after the diet is over. This leaves me with net weight loss of approximately 5 kg in 13 days. I'm repeating it every 2-3 years.

I absolutely think this diet works. 2.5 years ago I did this diet. Lost 19 pounds in 13 days and kept it off untill recently when by my fault I started eating a lot. Its little tough first few days but I think it's all mental game. It helps if you have all meals prepared ahead ( i had someone do it for me) so it was easy to follow. If you do cheat even with a small candy ( anything out of the diet) it will not work and yoh can stop it. Try in few months again. I was eating normal after I was done with the diet, always freaking out that I gained pounds next day but it did not happen. Great way to take a first step towards healty living. I will be doing it again in few days and hope it works again!!! You can do it its only 13 days. If anything its great way to detox your body from all the junk we put in. Good luck.

I am on Day 8 and have lost 4 KG so far. I was 70 KG and 168 CM tall. So losing 5% of my body weight in a week's time is a healthy and acceptable weight loss for me. I am happy about the result but will definitely continue to watch what I eat and exercise regularly after the 13 days and forever to keep fit and healty.

this article is economic with the truth. My husband and I followed the diet. He lost 8 kg and I lost 4 kg in 13 days. it is not so rich in cholesterol, one eats 6 eggs in one week and not every day, the same with meat. it is very low caloric indeed as one can only eat small amounts of meat with lots of lettuce and spinach. No alcohol allowed. Fruits, yoghurt and cottage cheese are allowed.
