Not all dietary restrictions are beneficial for the female body. We talk about popular diets that can negatively affect our health.
The very concept of “diet” implies that for some time a person’s nutrition will be limited in one way or another. There are a huge number of diets that are suitable for someone and not for someone. The most balanced and healthy for our body is the Mediterranean diet, which is based on a large amount of plant foods, low—fat fish, seafood, legumes and whole grains. There are practically no people to whom these products could be contraindicated. But there are popular, fashionable, though quite dangerous to health diets that have a number of side effects. Expert endocrinologist, specialist in preventive and anti-age medicine, Elena Ostrovskaya tells you before which diet you need to undergo a mandatory medical examination, or even better — consult a doctor.
This food system has long been very popular, including among athletes and show business stars. There are many protein diets, and perhaps the most advertised and well—known of them is the Dukan diet. It is based on the fact that a large amount of protein is present in the human diet, and the amount of fat and carbohydrates is limited. The main advantage of this diet is that it is really effective, a person loses weight quickly primarily due to the loss of adipose tissue and water.
But such a food system also has contraindications. Not for every body, a large amount of protein is useful, a few months after following a protein diet, people may face such a problem as the formation of gallstones or renal colic. The fact is that with excessive consumption of protein products, the level of uric acid increases. If there is a predisposition to urolithiasis or a tendency to the formation of kidney stones or gallbladder, then it is better to refrain from this type of diet.
High levels of uric acid also contribute to the appearance of gout, and gout is not only joint pain, but also secondary changes in the kidneys. It is impossible to get rid of these problems quickly. It is necessary either to constantly relieve pain attacks of renal colic, or to remove stones.
Thus, even by reducing weight with the help of a protein diet, you can put your overall health at risk. Therefore, before you start observing it, you should definitely visit a therapist, and ideally an endocrinologist, and examine kidney function, uric acid levels and other parameters.
On keto diets, fat becomes the main source of energy for the body. When it decays, it forms ketone bodies, and thanks to this energy, a person feels cheerful and well. It is quite comfortable to maintain a keto diet, especially when the acute period of entry passes. Usually adaptation takes place within a week, but it all depends on the individual characteristics of metabolism.
On a keto diet, the level of protein content in foods is not as high as with protein diets, but it is impossible to completely exclude proteins, they are needed for metabolism. But carbohydrates with keto diets are minimized to critically low numbers. Initially, this diet was used to treat children with neurological pathology and epilepsy, in whom carbohydrate intake causes deterioration of the general condition. Now they have become popular with those who want to get rid of excess weight.
The keto diet also has contraindications. For example, you need to know that excess fat is a fairly large load on the pancreas. If a person has chronic pancreatitis or disorders of the intracretory functions of the pancreas, as well as diabetes mellitus, problems with the stomach or cardiovascular system (atherosclerosis), then consuming a large amount of fat for a long time can lead to negative consequences. If you want to try this diet, get examined by a cardiologist and gastroenterologist.
Vegetarian and vegan diets
The vegetarian diet needs no introduction. It involves the rejection of animal products, but allows fish, milk and fermented milk products to be consumed. Veganism is a stricter version of vegetarianism, which in principle does not allow the use of animal food. Strictly speaking, veganism is more of a philosophy, not just a diet, and people choose it for ethical, religious or medical reasons. Many vegans claim that by eating only plant foods, they experience an incredible surge of strength and energy, and they have absolutely no need for animal protein.
Veganism from the point of view of a doctor is a rather dangerous type of food. The body is experiencing an extreme deficiency in certain nutritional nutrients, in particular, in animal protein, where there are essential amino acids. Vegans, as a rule, have a deficiency of iron and vitamin B12, which is found exclusively in animal products.
You will need
Oddly enough, vegans often have high cholesterol. This is due to the fact that the liver, in order to compensate for the lack of cholesterol coming from the outside, begins to synthesize it. After all, it is needed for the production of adrenal hormones, sex hormones and brain function.
It is also worth noting that some people have specific genetic features of assimilation of substances from plant products. For example, their body simply does not accept some vitamins and nutritional nutrients. The person himself may not know about it. If you are determined to become a vegan or vegetarian, then it is necessary to be examined and consult a doctor. A doctor or a nutrition specialist will help you choose a balanced complex of vitamins, trace elements and nutritional nutrients that you will receive additionally.
Juicing or juice diet is another fashionable and popular trend in the pursuit of weight loss. It is based on the fact that people consume freshly squeezed juices from fruits and vegetables several times during the day, eat only liquid vegetable food. It is forbidden to eat during a juice diet, since juicing is used as a good detox, that is, a radical cleansing of the body from the inside.
Usually nothing is added to these juices, not even sugar. On such a diet, you can really lose weight, because juices are easily digested, low in calories and do not contain fat at all.
Juicing as a diet is good only for a short time, but some people, getting carried away with this type of diet and getting euphoria from rapid weight loss, linger on it for a long time. Freshly squeezed juice contains fast carbohydrates and fiber that is easy to absorb, so a person feels a surge of strength, but only for a short time.
Malnutrition in juicing is evident. Carbohydrates are disposed of quickly enough, and there is practically no protein in the juice, which is so necessary for the full functioning of all organs and systems. In addition, natural juices have a sufficiently high acidity and irritate the gastrointestinal tract, which can cause dysbiosis. It will be quite difficult to correct it later.
Before practicing a juice diet, it is necessary to consult a therapist and a gastroenterologist with a minimum list of examinations. And if there are no contraindications for health, then you can try juicing as an express detox for a maximum of one or two days.
Fans of raw food believe that it is necessary to consume exclusively “live” products in their original form, and not heat-treated. Moreover, raw food is not equal to vegetarianism, raw foodists can include raw fish or even meat in the diet.
With raw food there is always a danger in the failure of physiological processes in the body, first of all the stomach suffers. Acids, which are contained in fruits and vegetables, get on the mucous membrane and cause its irritation. In “live” food, all the vitamins and trace elements necessary for life are really preserved, raw foodists are right about this. But these nutrients will not be properly absorbed, because the inflamed gastrointestinal tract simply will not be able to process them properly. In addition, with the use of a number of raw foods, there is a high risk of getting parasitic diseases.
If you decide to switch to a raw food diet, then the transition should be gradual. It should be preceded by a thorough examination by a gastroenterologist. In no case should raw food be present in a person’s life on a permanent basis, this is not a very good practice. A change in eating behavior will give a feeling of lightness and a surge of strength only for a short time. When the diet is prolonged, especially in our not very hot climate, it can lead to exhaustion of the body and failure of all physiological processes.
Many people experiencing problems with excess weight say that it is easier for them to starve than to diet. Such people prefer to go to the clinic for detox procedures, where they will have their stomach and intestines washed, or simply refuse to eat for a while. Proponents of fasting say that the refusal of food activates the internal forces of the body, while toxins are excreted, a feeling of vivacity appears. But you need to enter into fasting correctly and, more importantly, you need to get out of it correctly. It is difficult to do this independently and without preparation.
Fasting as a way to get rid of excess weight is better not to use. Many people, refusing food, lose weight, but then rapidly gain weight, because the body will begin to digest food much faster when the restrictions end.
With all this, therapeutic fasting does exist — it is a developed technique, it is used in clinics under the supervision of a doctor and, as a rule, for a fairly short time. Fasting can be effectively used for the treatment of allergic diseases such as atopic dermatitis, severe bronchial asthma, sometimes for the treatment of rheumatic diseases, but it should never be used for weight correction. In addition, fasting has many contraindications. For example, if a person has anemia, problems with a deficiency of protein, iron, trace elements and vitamins, then fasting can definitely worsen his health.
