Risks of wanting to lose weight without medical advice
The Time magazine recently devoted its front page to a practice that makes furor among obese Americans. However, as this report reveals the Argentine daily La Nacion, some specialists from other countries are suspicious of the boom of the diets very low in calories and rich in protein. The risk is that the agency devore their own flesh and the resulting dehydration causing a fatal cardiac failure.
Want risking their lives? Start on your own any diet book or any magazine, or those that come in envelopes and serve to prepare smoothies and soups that reads the tag-as-replace a meal. While not all are equal, are based on a similar principle: the sudden and dramatic suppression of carbohydrates at the expense of a higher consumption of fats and proteins.
Resounding no to bread, pasta, rice and sweet biscuits; themselves to meat, eggs, milk, and even cold cuts and sausages. Vegetables and fruits, minimum quantity. These diets are not exactly low-calorie (can take about 1,500 daily), and promoted by ensuring that one can eat up Hart, but as produce nausea and an upset stomach (among other things more risky) after a few days people have less appetite.
There are other diets that are less generous. In English, they are called very low calories diets (Vlcd), which means diets very low in calories. They include between 400 and 800 daily and, although they may prepare food (we need a real expert to tell not too much), also come in envelopes (or bottles), forming a mixture of nutrients in which carbohydrates exist, but in very low quantity.
Why so much bitterness with these nutrients? “The carbohydrate-explains Dr. Brandi, director of the Center for obese Italian Hospital and former president of the Sociedad Argentina de-Nutrition retain water and sodium. If they are deleted, the body increases its urine output. Then he drops weight , Which is not equal to lose weight. Weight loss is weight loss at the expense of fat, not water or proteins. Dr. Escobar, endocrinologist, a teacher at the University of Buenos Aires, added: “All these diets have a common ground: when not eat carbohydrates can not synthesize new or store fat. But this is not healthy.”
Risks and rewards.
At this point it is reasonable to have a basic question: whether the muscles and brain-eating sugar, Àde what living when removed drastically carbohydrates?
“In principle,” says Escobar, the ketone bodies that are formed in the liver when new fats, which can not be stored, go there. The brain can not wait for food, so when the reserves have been consumed sugar (and this happens when not eating carbohydrates), the body, using a rescue mechanism and to avoid going into a coma, uses ketone bodies for energy. But they have a counter: drag sodium, potassium and thus, water. The person is dehydrated, why lose weight.
In addition, feels weak, tired, with bad breath. That is why he is not suggesting physical activity, a mainstay of treatment. ”
So the brain eventually wants sugar. And the only source of glucose that remains are proteins. “Therefore, when making these kinds of diets-adds-Escobar, the day after the person has to consume their protein for energy. In other words, he loses his own lean mass, are undernourished, and this happens even if overweight. We must remember that 70% of caloric expenditure is done muscle, which is protein. As the agency receives fewer calories, start saving and makes consuming its own muscle to reduce the total caloric expenditure. ”
The big problem is who lose muscle mass until the organs, including the heart. So the risks include sudden death, cardiac arrhythmias, hypotension and the inability to determine whether such a mobilization of fat will increase or decrease cholesterol and lipids. In addition, because apathy and lack of concentration. “The diets of American style, also called decoupled, are not recommended at all-consuming states-As many foods high in fat, cholesterol increases. Yes recommend diets very low in calories for individuals with very overweight, because although they are aggressive , May help diminish rapidly several kilos and lower your risk: a hyper-obese, often suffering from breathing difficulties, hypertension, high cholesterol, diabetes, joint problems. They have to follow very strict medical supervision and for a short period, for example, one month “.
Medicaid distrust.
The Vlcd became sadly famous in the mid 70’s, when 50 people died, some young and healthy, as a result of acute cardiac disorders. “That’s why he added high biological value proteins, minerals, vitamins and amino acids,” says Escobar, and a low percentage of carbohydrates to prevent the body from so quickly to use ketone bodies. But still risky. Only we can in cases of hyper-obesity, and the patient to control it well. ”
Dr. Brandi, however, believes that much of the criticism on Vlcd have some exaggeration. “You do not need international adds.” Yes they have a daily control, but can continue working. ” For Brandi, the real reasons for a person to reach 150 kilograms and eat so unconscionable have some genes and elsewhere in mystery, but assures that a part of the problem is due to the “misconduct of obese,” not incorporates best habits. “Of course, such diets, in addition to hazardous-adds-Escobar, not conducive to learning any new behavior. Any diet of less than 1,200 calories per day has always deficit of nutrients, and more if a group of them is virtually eliminated . It is normal that after these diets return to the meal with the same kind of attitude than before, or worse, and win quickly lost weight, faster than when it followed a full meal plan. ”
Both Brandi Escobar as suspicious of the good results of American diets, which Time magazine recently conducted a lengthy article. “Mentiras”, dice Brandi. “Lies,” says Brandi. “The number of successful cases not have statistical significance,” says Escobar.
The serious problem is that overweight people-mostly women-are behind the diets with the aim of lowering 5, 10 or even 15 kilos in a hat. “I do not know that and are very low in calories as hyperproteinic and hipergrasas, subjected her body to a huge assault-Escobar argues.
A slimming diet must be complete. We recommend that you choose complex carbohydrates, not simple sugars-ie , Candy, lowering saturated fats and proteins provide sufficient. So too will join the fewer calories are spent, and will give you the missing energy that the body needs to live in reserves of fat.
