Before discussing this topic, we should first realize that in order to maintain life, the body must obtain energy (nutrients) from food, if the body needs as much as we get, that is good. But people in famine or war years, often because they do not get enough food, increasingly thin and weak; nowadays, however, the days are better, what you want to eat, as every day, like the New Year, the energy obtained is often greater than the demand, so the excess energy eaten will become our body fat. Obesity is caused by long-term bad eating habits, even if each meal is just one more bite, excess energy gradually accumulates in our body and we slowly become fat. The use of these body fat is stored is once in the body can not get food in a timely manner, through the body fat metabolism, to provide energy for the body to replenish. Over the millions of years of human evolution, body fat has played an extremely important role in maintaining individual life and reproducing offspring. Since body fat has such an important role, is it better to have more body fat stored in our body? In fact, too much fat is harmful to the body and is often the culprit of the “three highs”. After extensive research, the medical community has reached a consensus that the total amount of body fat stored in the body should account for 18% to 22% of body weight is appropriate. For a long time people have come up with many fat reduction methods, some of which are desirable, some unsatisfactory, and even some are fraudulent and money-making. We might as well analyze them one by one. 1, sports and fitness: this method is more scientific. But it is best to have expert guidance to avoid strain injuries caused by improper exercise, people who are seriously overweight, pay special attention to protecting the knees, choose something that does not overload the knees. 2, eat certain drugs that can cause diarrhea: this method is less desirable. Because diarrhea can make potassium and other electrolyte loss, weakness, bloating and other phenomena. Seriously will affect the health. And long-term diarrhea, the face will also be poor. 3, eat roundworms (eggs): this method is not advisable, take roundworms as “pets” to raise, not like cats and dogs as humane, extremely dangerous. Roundworm eggs hatch after reaching the small intestine, and the larvae pass through the intestinal mucosa into the lymphatic vessels or small veins, reach the lungs through blood circulation, then enter the lung alveoli through the small blood vessels in the lungs, then enter the bronchi, throat, esophagus, and then reach the small intestine through the stomach and develop into adults. Roundworms that take the wrong path in the body can cause biliary ascariasis, intestinal obstruction, intestinal perforation, liver abscess, blindness, epilepsy and other diseases. In addition there are roundworms in the body, the facial skin will be piece by piece like ringworm, affecting the appearance. 4, eat certain weight loss drugs: this method is basically undesirable, taking diet pills can achieve the purpose of weight loss, but these drugs need to be degraded by the liver or kidneys out of the body, so the liver and kidney damage is more serious, taking diet pills caused by kidney failure, cirrhosis, liver necrosis clinical reports are quite common. 5, eat certain drugs that can excrete fat through the stool: I think this statement is fraudulent, do not believe, and do not take. First of all, from the physiological point of view, it is impossible for body fat to reach the intestinal wall from the subcutaneous or abdominal cavity, and then reach the intestinal canal through the intestinal mucosa. We all know that protein, fat and carbohydrates are the main energy source of the body. Just imagine, if someone eats carbohydrates, the energy source is not used by the body, but a large amount of sugar is excreted through the urine, and the person can enjoy the food without gaining weight, is this phenomenon normal? Absolutely not normal, because he is suffering from diabetes. If someone eats meat, fish, eggs, milk and other protein-rich food, the energy is not used by the body, but a large amount of protein excreted through the urine, people can enjoy the food, but not fat, this phenomenon is normal? Absolutely not normal, because he suffers from kidney disease. Then, if someone eats, the energy is not used by the body, but a large amount of fat excreted through the stool, people can enjoy the food, but not fat, this phenomenon is normal? Absolutely not normal, because he is suffering from a currently unknown, can make a large number of body fat loss of strange disease, it is estimated that his health, and even life expectancy will be greatly reduced. 6, in the plantar patch drug can discharge fat: this type of propaganda is pure deception, because there is no subcutaneous fat under the skin of the human foot, both there is also impossible to seep out of the skin. Some of us often “oil” on the face or back, that is also by the sebaceous glands secretion of sebum, not body fat. Sebum moisturizes the skin, while body fat is the body’s stored energy, and they are very different. The way to pierce the fraud is very simple: weigh the new foot patch with a balance, record the weight, and then paste it on the bottom of the foot, and then weigh the weight of the foot patch that absorbed the sweat and shed skin after use, and the weight difference between the two is both sweat and skin weight, and then dry the used foot patch in the sun or dry, at this time the weight lost is the weight of sweat (because sweat can evaporate while body fat is not evaporable). At this point, the weight of the dried and new foot patches compared, it is estimated that there is almost no difference. 7, massage for weight loss: this method works. For those who are afraid of acupuncture, the advantage of this method is no fear, the disadvantage is more time-consuming (including waiting), and to ensure the effectiveness of the treatment, the pain is sometimes even more than acupuncture. 8, vibration weight loss: This method, if effective, is also the result of the need to cooperate with diet. Some places say: vibration can shatter fat cells, and some say that vibration can “burn fat”. These claims are not scientific. Especially for those who have cholesterol deposits in the walls of the blood vessels, be careful, if these deposits once the violent vibration and dislodged, the formation of emboli, embolism in the lungs or brain, that can be a life-threatening disease. 9, in order to prevent fat, or to lose weight, after eating key throat, vomiting out of the food eaten: this method is really not desirable. Chinese medicine believes that “the stomach to drop for the smooth”, said the diet into the digestive system, will be because of the esophagus, stomach, intestinal tube of the top-down continuous peristaltic movement and decline, this decline is in line with the physiological needs. Only when there is a foreign body in the throat, digestive system tumors, intestinal obstruction and other intestinal obstruction, the body will reverse peristalsis, causing vomiting. If you often pick your throat, in the long run, will produce a conditioned reflex, the phenomenon of food into the vomit, the body will not get the necessary energy to replenish for a long time, the terrible consequences of multi-organ failure. 10, acupuncture weight loss: I think this method is the best. In the end how good, who treats who knows!
