Nowadays, all kinds of weight loss methods can be described as varied and strange, and the effects are also different. Next, let's compare seven popular ways to lose weight. Principle of drug weight loss: weight loss drugs are mainly divided into three categories. One is appetite suppressant, which stops you from eating by inhibiting the central nervous system; One is to accelerate the excretion in the body, which contains diuretics, rhubarb, senna and other ingredients, which can directly transfer the water in the human body from the body; The other is drugs that help burn fat and calories, which greatly increase the energy you consume every day and expel the fat you eat. Advantages: It is a relatively fast way to lose weight, without dieting, and it is convenient to take. Disadvantages: once the drug is stopped, the weight will rebound like a god. Miss Wang once asked someone to bring a diet pill from abroad. After taking it, she lost weight 10 kg in the first month. As she was obviously much weaker, she stopped taking medicine. Unexpectedly, at this stop, the weight soared. In half a year, her weight rose from 98 kg to 160 kg, and she could not lose weight. Moreover, it is a three-point poison. Long-term use of diet pills will have adverse effects on the nervous system, cardiovascular system and kidneys. So far, there is no drug in the world that can effectively lose weight without any adverse reactions to the body. The principle of hunger to lose weight: First, reduce food intake, reject staple food and carbohydrates, and only eat fruits, vegetables or soup; The other is picky eaters, which take care of the food, then sneak into the toilet, pick the root of your tongue with your hand or toothbrush, and spit out the food you just ate. Advantages: no side effects of drugs, no strenuous exercise and no surgical pain. Disadvantages: dieting to lose weight sounds "natural", but it is actually dangerous. It will cause malnutrition, decreased metabolic rate, anemia, decreased immunity, inattention, and loose and dull skin. Although the weight loss effect is obvious, it is easy to rebound. Once you stop dieting, hungry cells will indiscriminately absorb nutrients and aggravate obesity. And after a long time, it is easy to lead to anorexia and endanger life. Frequent throat buckling also has many sequelae. In the process of vomiting, in addition to spitting out food, gastric acid and electrolytes will also be spit out. Gastric acid will erode the enamel of teeth, lead to tooth decay, and even make the skin of fingers fester in severe cases; Spitting out electrolytes will increase the heart load. In addition, long-term choking can lead to many diseases, such as diarrhea, habitual vomiting, malnutrition and so on. Principle of losing weight by exercise: improve basal metabolic rate through exercise, make body fat burn quickly and control body weight. Advantages: While losing weight, it can also improve cardiopulmonary function and prevent cardiovascular diseases. It is a healthy and effective way to lose weight. Disadvantages: Not all sports have the effect of losing weight. After strenuous exercise, the blood sugar level will decrease, which will greatly stimulate people's appetite. If you are not careful, the calories you eat will exceed the calories you consume during exercise. Short-term exercise, such as aerobic exercise, lasts only about 1 hour. At this time, the fat has just begun to decompose, but you have stopped exercising. How can I lose weight? There are also rapid and explosive sports, mainly white muscle fibers with thick cross sections. Losing weight like this will only get stronger and stronger. Even if you reach your ideal weight through proper exercise, it doesn't mean you have lost weight. Once you stop exercising, you will gain weight again. Only by long-term exercise can we keep fit. The principle of liposuction to lose weight: make a small incision in the part that needs liposuction, extend the liposuction tube into the fat layer, and then suck out the fat through the negative pressure of the liposuction machine. Advantages: It only takes half an hour to 1 hour to lose weight immediately, and you can go wherever you want. While losing weight, you can also shape the slender curve of your body. Disadvantages: pumping only one part will lead to uncoordinated body proportions. For example, liposuction with both arms will make your back fleshy, so you should do liposuction on your back again. Wear tights after surgery. If you are hot and sweaty, it will be difficult to recover for more than a month. Massage should be done frequently after operation, otherwise the local skin will become unsmooth and the congestion will not fade easily. If you don't pay attention to adjusting your diet, your weight will still rebound, just like before the operation. In addition, experts say that liposuction only sucks the subcutaneous fat away, and the visceral fat is still there, so it can't reduce the risk of cardiovascular disease. Acupuncture weight loss's principle: Stimulating acupoints with acupuncture can regulate the metabolic function and endocrine function of human body, promote lipolysis, inhibit gastrointestinal peristalsis and gastric acid secretion, and relieve hunger. Advantages: Known as the most "green" method to lose weight, it can also regulate meridians and endocrine while losing weight. As long as acupuncture is carried out in a regular big hospital, it is still relatively safe and reliable. Disadvantages: Chinese medicine pays attention to conditioning, so the effect of acupuncture weight loss is slow. At the same time, acupuncture should also be based on physical fitness, and different acupoints should be tied according to different physical fitness. If you go to an unqualified beauty salon for acupuncture, you may hurt your heart, lungs and liver and even get AIDS because of improper acupuncture. Principle of reducing weight by gastrostomy: The normal stomach capacity is about 1000 ~ 1200 cubic centimeters, but after this operation, the stomach capacity is only 20 ~ 30 cubic centimeters. If you eat very little, you will feel full. This kind of operation is rare in China at present, but it is very popular in Japan and Europe and America. Advantages: You can definitely lose weight, and studies show that the incidence of fatty liver, hyperlipidemia and hypertension decreased from 82% to 3%, 72% to 5% and 46% to 5% respectively after operation. Disadvantages: This operation is considered as the "last resort" to treat obesity. The operation requires general anesthesia, which has certain risks and may cause gastric laceration and gastric bleeding after operation. In addition, due to the shrinking stomach, vitamins and minerals obtained through food may not meet the needs of the body, and some extra vitamins need to be added. Only suitable for those who are seriously overweight. Weight loss principle of instrument: one is a large instrument used in beauty salons, which sucks out the fat accumulation place through vacuum sucker, and massages and vibrates slowly with low current to help muscles move, so as to dredge lymphatic vessels, eliminate toxins and eliminate excess fat. The other is the fat buster, which once sold well in TV direct sales programs. Through electric current vibration, the fat of obese parts such as arms, waist and legs is crushed. Advantages: Suitable for lazy people who are afraid of hardship. Disadvantages: Although the beauty salon's slimming instrument is comfortable, it has little effect, and it often costs a lot of money but can't see the effect. The violent vibration produced by the skimmer can cause visceral displacement and even mechanical damage; It can also inhibit gastrointestinal peristalsis and gastric acid secretion, resulting in gastrointestinal symptoms such as fullness and pain in the upper abdomen, leading to high incidence of gastrointestinal diseases; Women can also have prolonged menstrual period, menorrhagia, dysmenorrhea, uterine prolapse and so on.
