In much of the medical literature, obesity is directly referred to as a chronic disease. It doesn’t matter how much obese people try to cheer themselves up: call them overweight people instead, or celebrate freedom and diversity. Today obese girls are 20% more likely to be unavailable than girls of the same age who are normal weight but have other chronic diseases, and 10% more likely to have financial difficulties; boys are 11% more likely to be unavailable. Obesity is most commonly defined by the body mass index (BMI), which is the number of kilograms of body weight divided by the square of height in meters (body mass index (BMI) = body weight (kg) รท height^2 (m)). In the West, 25-29.9 is considered overweight, and reaching 30 is obese. However, the standard for Asians is 23-24.9 as overweight and 25 as obese. Obesity increases the risk of many diseases, including cardiovascular disease, diabetes, sports joint disease. What can save the obese from blaming themselves is that genetic factors play an important role in obesity. Even adopted children still look up to their biological parents in size. Obesity genes have not played a screening role in human evolution, otherwise, according to that trend above, it would not take several generations for obesity genes to be diluted in the gene pool. But now the proportion of fat people is still growing year by year, and this trend is only a few decades old, almost negligible compared to human history. But for this trend, the obesity gene might never have been discovered, and even if it had been, it would not have attracted much attention. If it were not for acquired environmental influences, such as more and more food, larger and larger portions, less and less need to walk, etc., the obesity gene might never have been useful. Obesity problem if the zombies in the tomb, can run to the light of day to wreak havoc is also a mess of digging and digging of human beings themselves to invite out. Anyone who wants to lose weight naturally without pills and surgery, but the experience of countless people confirms that weight loss relying on lifestyle adjustments, including dieting and exercise, is quite difficult, unless it is under significant stimulus and threat. At this point, the perseverance of athletes is nothing to envy. I used to think that athletes’ coaches were dispensable people who made a plan and stayed on the sidelines, until one year after I couldn’t resist hiring a personal trainer at the gym. To put it bluntly, coaches play the role of supervision and encouragement. Those exhausting exercise program if only by their own perseverance, in any case can not be completed. Under the premise of no one’s supervision, unless one is diagnosed with diabetes or has experienced a near-death myocardial infarction, it is only possible for one to sustain perseverance. Essentially there is no difference, but the trainer has been replaced with a vague grim reaper. Even though diet and exercise do not result in lasting weight loss, proper exercise is still advocated. According to research studies, although physical activity does not shed pounds, it reduces the risk of heart disease-related deaths and is more conducive to diabetes control. In other words, exercise does not remove weight, but it has cardiovascular benefits. In addition, most people with type 2 diabetes have insulin resistance: insulin levels are not low, but the body does not respond to insulin. Appropriate physical activity can increase the body’s sensitivity to insulin, thus enabling it to keep blood glucose stable while reducing insulin dosage. Regarding the type of physical activity, excessive overload is generally not recommended because it will promote appetite even more. A small amount of exercise intermittently every day is the best way. In fact, to put it bluntly, the purpose of exercise is to change the living habits of lazy people, only when they are not lazy and love to move, can they get lasting weight loss. You can imagine how difficult it is. Drugs and surgical methods of weight loss should only be considered after efforts to change habits have failed, or in certain patients who already have type 2 diabetes. The mechanism of drugs is simply to suppress appetite and reduce fat absorption. Surgery, on the other hand, works by altering the structure of the digestive tract to reduce the amount of time and area where food comes in contact with the gastrointestinal tract and reduces the absorption of food. People who are ready to choose between medication and surgery need to be aware that, according to research, medication and surgical treatments are only more effective in people who have had previous success in losing weight through diet and exercise. The truth is that even medication and surgery are not a permanent solution, it comes down to changing habits. There are many weight loss clinics and weight loss clubs available and there are people who claim to have successfully lost weight in these clinics and clubs. There are so-called herbal, acupuncture, massage, Chinese medicine and so on, and these are not out of the realm of modern medicine either. Bringing together many people who want to lose weight and bringing them together at regular intervals for communication and supervision actually falls under the category of psycho-behavioral treatment of obesity. Spend money, listen to the class, someone to supervise, of course, than their own die hard easier. When it comes to Chinese medicine to lose weight, in fact, there are many foreign countries, such as the United States, there is a huge market of 3.3 billion U.S. dollars, naturally, there is no shortage of Chinese medicine practitioners with a sensitive sense of business. However, there is no evidence to support any kind of Chinese medicine has a weight loss effect, and at the same time the safety can not be ignored. Once the most used ephedra in 2003 because of safety issues by the FDA issued a consumer alert banned, aristolochic acid nephropathy is also earlier in Europe, herbal weight loss clinic customers were found. In short: obesity is a disease, life to regulate; weight loss is no miracle drug, lazy people without medicine.
