The ketogenic diet is a diet based on the assumption that a diet rich in protein and fat, with low intake of carbohydrates keeps insulin levels steady ii avoiding the accumulation of fat and promoting its use to for energy. Decreasing the levels of glucose above the recommended limits, the body will be forced to take energy from other substrates, consisting of proteins and lipids.
In many, with the advent of summer, and subjected to much unnecessary pounds, embark on a ketogenic diet. But what do you mean specifically and what is actually on this diet? When it comes to
ketogenic diet, it comes to special diets, based on the drastic reduction of carbohydrates in order to lose weight. The daily caloric intake is then provided almost exclusively by the recruitment of fats and proteins.
From physiological point of view, the ketogenic diet shifts the body's metabolism to the beta oxidation of fatty acids and production of ketone bodies (hence the adjective ketogenic). In other words, the body that normally synthesizes (burning) carbohydrates to produce energy, enhances its ability to oxidize fat for energy. This process, however, is not effective, since it leads to the production of toxic waste called ketone bodies.
ketogenic diets allow you to achieve rapid weight loss and this characteristic has greatly contributed to their spread. In a few argue that the initial reduction in body mass is due to degradation of glycogen and water loss.
Only a few days later, taking advantage of the satiating power of fats and proteins, the body begins to feel the effects of diet lost much weight since this diet leads to a reduction in energy intake resulting in the long run, a considerable loss of body fat.
The ketogenic diet entails, however, risks for the organism, among which we can include dehydration, electrolyte loss, inadequate intake of fiber, calcium and vitamins, the occurrence of gout and kidney problems (because of 'high protein).
ketogenic style food, which has taken hold in recent years and should be abandoned in favor of more healthy and balanced diet.
in treatment, the ketogenic diet is recommended for children under the age of 10 years suffering from epileptic forms not completely controlled by medication. The establishment of a state of ketosis is in fact related to a reduction in the incidence of seizures.
gluconeogenesis is a process that leads to the formation of glucose from certain amino acids from the carbon backbone. This process ensures a constant supply of electricity, even in conditions of lack of glucose but it forces the liver and kidneys to work more to remove nitrogen.
Avoid taking glucose through diet and forcing the body to break down the proteins a process is inconvenient, because it poisons the whole body doing unnecessary work.
The ketogenic diet, due to the intake of fats and proteins, can cause severe problems such as ketosis and iperuremia, namely the increase of concentration of ketones in the blood. The human body needs glucose to survive. The essentiality of glucose as an energy source is connected to the fact that the central nervous system uses glucose exclusively to conduct its activities as well as the cells are dependent on glycolysis for their energy metabolism. It is estimated that the minimum daily intake of glucose for the normal functioning of these systems is 180 grams. Lipolysis, ie the degradation of fatty acids for energy is linked to glycolysis. If for any reason glycolysis and the Krebs cycle are very slow, then lipolysis is impaired and are formed ketone bodies and fatty acids are normally degraded to acetyl CoA which enters the Krebs cycle to oxaloacetic acid by binding to a further oxidation to carbon dioxide and water. If the production of acetyl CoA through lipolysis, exceeded the absorption capacity of oxaloacetate, ketone bodies are formed. There are three ketone bodies: acetone, acetoacetate and 3-hydroxybutyrate. Ketone bodies are formed from two molecules of acetyl-CoA, which can not enter into Krebs, associate with each other. They are normally produced in small quantities that are easily disposed of the body, especially the kidneys and lungs. If the production of ketone bodies becomes much their high accumulation in the blood, called ketosis, lowers blood pH resulting in metabolic acidosis: this typically occurs in untreated diabetics. In extreme cases, the acidosis can lead to coma and even death. The problems are exacerbated when the subject performs an intense sport, increasing demands and the oxidation of glucose by the body.
Although exercise increases the capacity to oxidize these substances for energy, as opposed to all the negative effects of their accumulation in the blood stream, the use of the ketogenic diet remains a force metabolism, which can cause consequences in the long run unpleasant, even in a young body and well trained.
One can easily conclude that the ketogenic diet works both now subjects the body to a constant stress and not at all healthy. Therefore, this diet must be replaced with other diets to be equally effective and less harmful.
