The Copenhagen diet gives surprisingly fast results, but it is associated with many sacrifices, as the amount of calories delivered is not more than 800. The weight loss treatment is scheduled for only 13 days, hence the term "miracle diet". You have to set yourself up for this time to be accompanied by constant hunger. What's more, the Copenhagen diet has a 13-day diet, and any deviation from the guidelines results in the discontinuation of the weight loss treatment. It should also be mentioned that if you choose a snack that is not included in the menu, you stop your diet, and you can only return to it after three months. Answer the question yourself, is it worth it?
The diet is very strict and burdensome, so it can be used at large intervals. Although after interrupting the treatment you can come back to it after a period of three months, ending it - you can try again only after two years.
The Copenhagen diet is associated with a number of restrictions which, if not adhered to, will result in discontinuation of the treatment. However, if you follow the recommendations after the first day, you will notice a weight loss of about 0.5 kg. If you follow the Copenhagen diet, you can expect a weight loss of up to 15-20 kg. What is more, at the end of a 13-day weight loss treatment you cannot forget to introduce healthy eating habits into your life. This is all the more important because returning to bad habits contributes to the yoyo effect. Why does this happen? The Copenhagen diet contributes to weight loss, but it is mainly water, nutrients, complex carbohydrates and fibre, which quickly return to normal levels when you finish your diet.
As it turns out, the Copenhagen diet has its supporters as well as people who are sceptical about it. Many people are unable to face the restrictions, so they decide to discontinue it. This is related to bad mood, irritation as well as annoying weakness. Without a doubt, this is a diet for people with strong will and who are properly motivated. The Copenhagen diet can be used as an introduction to good eating habits. It is also worth noting that the Copenhagen diet is not recommended for minors or elderly people, as it causes them to give up the calories and nutrients that are very much needed at this age. What is more, if you do sports or rely on physical activity, this diet is not for you. This is due to the fact that by using it we provide too little nutrients to the body, which can be very harmful. 
The diet lasts for 13 days and has a predetermined menu, from which there are no exceptions. By choosing this treatment you can forget about cereals, alcohol, sweets and salty delicacies. The Copenhagen diet consists of 3 meals a day: breakfast (between 8 and 9 am), lunch (between 12 and 2 pm) and dinner (until 6 pm). The effectiveness of the diet is dictated by observing fixed hours for meals without snacking between them. Once you have made a deviation from your diet, you must start the diet from the beginning, but only after a period of three months. It is necessary to take at least 2 litres of water per day. 
To avoid the yoyo effect, it is necessary to change your eating habits for the better. This is all the easier because the Copenhagen diet itself can be treated as training for a new lifestyle. In addition, you can minimize the yoyo effect by switching from a Copenhagen diet to a thousand-calorie diet. Furthermore, it is recommended to follow a balanced diet and add physical activity to the lifestyle.
The Copenhagen diet includes a very strict menu, which includes coffee. Coffee is important because it provides the body with an extra portion of energy. Although it limits carbohydrates and fats, it is also important to remember about eggs, vegetables, lean meat and fruit, which can be eaten in small quantities.
It should also be mentioned that the Copenhagen diet forces you to give up physical activity for a period of 13 days. It can lead to greater fatigue, worse mood and thus minimize your motivation to lose weight.
