The Most Dangerous Diets

If you decide to lose weight – be careful what kind of diet you will choose. The desire for rapid weight loss can be very harmful for our health. We bring you a list of the most dangerous diets …


Mono diets promise a loss of 3 to 10 kg in one week. The diet is based on the fact that a person can only eat one particular food in a day or one same food all week. So for breakfast, lunch and dinner one can eat in any quantity, but only the chosen product. The most commonly proposed foods are buckwheat, tomatoes, grapefruit, yogurt, watermelon and other low-calorie foods. It is necessary to exclude spices, salt and sugar.

Why are mono diets harmful? Mono diet can lead to a deficit of nutrients in the body, the immune system become weak, the bones become fragile and the risk of anemia increases. The intake of same food may even develop an allergy to that particular ingredient.

Protein diets

Atkins diet and Hollywood are among the most popular protein diets. People that invented those diets believe that as fewer carbohydrates we consume, as leaner we are! This diet requires a total rejection of pasta, a minimum intake of fruits and vegetables, most meats and really offers fast weight loss.

Disadvantages of a protein diet – the person feels fatigue, nausea, bad mood and get an unhealthy color of the face. The maximum consumption of proteins with minimal carbohydrates usually leads to metabolic disorders. In addition, the body eventually starts to produce carbohydrates from fats to make up for lack of carbohydrates. It can be dangerous for the liver, heart and blood vessels.

Scientists argue that as more protein we eat, as more our body produces ammonia, which results in a negative impact on the reproductive system. Women who are on the protein diet are less likely to become pregnant.

Low-fat diets

Diets with low intake of fats are often categorized as extreme diets. The person must be excluded from eating avocados, nuts, certain types of fish, butter and other products that contain fats. One can lose about 3 kg in one week.

Disadvantages of low-fat diets – if the daily intake of fats drops under 19 percent, the level of “good” cholesterol, which protects the heart and blood vessels from atherosclerosis, drops. The lack of polyunsaturated fatty acids omega-3 and omega-6, for example, leads to urogenital disorders, or even infertility. Moreover, these amino acids help absorb vitamins A, D, E and K, which help our body break down fat. If we consume foods that are completely non-fat, then the liver will not be able to digest the accumulated fat. Nutritionists say that the optimal level of fat in the diet per day should be 35% of total daily calories.

The Japanese Diet

This diet is designed to last for 13 days. Menu is strictly designed for each day, and it really has absolutely nothing with the traditional Japanese cuisine. The Japanese diet is often compared with the Atkins diet and there are good reasons for it. Although most dishes are based on boiled potatoes, fried fish, chicken meat and raw eggs, it also prescribes a daily intake of cabbage, carrots, etc.. The key is to completely remove salt, sugar, alcohol, bread..

What can be achieved by the Japanese diet? One can lose about 5 kg per a week, and can be rid from surplus water. By the way, the diet devoid of salt is often used for medical purposes, for example in conditions of severe obesity and cardiovascular diseases.

Disadvantages of the Japanese diet – Nutrition experts recommend not to use too much of this diet. If you stay on it longer than 2 weeks, you will damage your digestive system and metabolism.

Express diets

If the diet is designed to last a week, then the probability of re-gaining weight is 95%.
If the diet is designed to last for two weeks, then the probability of re-gaining weight is 50-80%.
If the diet is designed to last three weeks, then the probability of re-gaining weight is 20-50%.
If the diet is designed to last for four weeks, then the probability of re-gaining weight is 8-10%, and so on and so on ….

When people choose the express diet? People usually go on a diet before holidays, weddings or other important events. They hope that the weight they have gained over the whole past year will disappear in only 5-7 days. The amount of consumed calories is not only minimized, those people practically starve.
Disadvantages of the express diet: This period of starvation leads to weakness, headache, nausea, indigestion and constipation. It is unlikely that you will feel happy for the duration of the diet, even if you manage to fit in your favorite dress. And most important, as shorter and more limited the diet is, the greater the risk of weight regaining is!
