I have been continuously consulted recently, how can I quickly lose weight?

　　Let us first understand what weight includes, and then only know how to lose weight. Body weight is mainly composed of water, muscle, fat, internal organs and bones.

　　 1. Moisture can be quickly reduced, and therefore quickly reduce weight. Diuretics (urine), laxatives (feces), steaming saunas or wearing plastic clothes (sweating) can reduce weight immediately. However, this loss of water can impair body functions, such as reduced immunity, fatigue, listlessness, etc., and once you add water, your weight will recover quickly ("rebound"). Some diet tea health products contain rhubarb, senna and other laxatives.

　　 2. Muscle can also be reduced quickly, the main method is hunger. When starving on a diet, the glycogen and protein in the muscle will break down one after another and take away the water in the muscle. Generally, for every kilogram of glycogen or protein broken down, 4 kilograms of water can be lost at the same time, and the total weight will drop by 5 kilograms. Therefore, strict diet will reduce weight in 2 or 3 days, but if there is no muscle, glycogen and protein can be broken down, then dieting can not quickly lose weight if you go hungry.

　　 3. Fat is stored energy, and mobilization is slow. In addition, the body does not have a way to excrete fat. Fat must be oxidized into carbon dioxide and exhaled from the lungs, so reducing fat is usually not too fast. Eating Youjiale (thyroid hormone) can improve basal metabolism, accelerate the conversion of fat into carbon dioxide, and can lose weight within a week or two (fat and muscle are broken down), but it is more harmful to health and will rebound after stopping the drug . Drug use also improves basal metabolism, can reduce body weight in a few weeks, and rebounds very slowly, but the harm is enough to be fatal. All drugs that increase basal metabolism have a rapid weight loss effect and have great side effects.

　　 4. Exercise can also promote the conversion of body fat into carbon dioxide, but because the calorific value of fat is almost the same as gasoline, it is more durable, so even if the amount of exercise is large, such as running for 1 hour a day, fat loss is also very slow of. The fatal thing is that the increase in muscles at the beginning of exercise counteracts the weight loss caused by fat loss, making the weight loss insignificant. Moreover, once you stop exercising, your weight will rebound.

　　 5. At present, diet pills (OTC) only have "orlistat" (Xenico, Immanin, etc.) that inhibits intestinal absorption of fat (making it flow out from the anus). After eating a fat meal, this medicine can inhibit intestinal fat absorption, but it cannot directly reduce the original fat in the body. So it can''t lose weight quickly, and it also takes a while (depending on how much fat you originally ate) to lose weight. The weight loss pills "sibutramine" (Qumei, Aoqu, etc.) that were commonly used two years ago are now banned. They play a role by suppressing appetite and reducing eating. Weight loss is also slow.

　　6. Liposuction surgery sucks local subcutaneous fat directly. Subcutaneous fat, water and blood are sucked out and thrown away, and you can lose weight immediately (off the operating table to see the effect, and the speed of amputation weight loss the same). Surgery has a certain risk, and it may still rebound, although it is difficult to accumulate fat in the local suction (because the fat cells have been removed, it is another matter if not all are removed) , But fat may accumulate in the surrounding areas or other areas.

　　7. Stomach reduction surgery directly reduces food intake (some also destroy intestinal absorption function) , You can lose weight within 1 or 2 months after surgery, and it is beneficial to some metabolic indicators (such as blood sugar, blood lipids, etc.). The risks and side effects of surgery are not mentioned here.

　　 8. A low-carb diet (that is, seldom eat staple foods, fruits and sugary foods, and high-protein foods such as meat, eggs and fish can eat more) can quickly lose weight within a few weeks because The result is reduced water, muscle and fat. Low-carb diets inhibit fat formation, accelerate urine excretion of protein metabolites (such as urea) and fat metabolites (such as ketone bodies), reduce body water content, and have health risks (similar to dieting hunger). Moreover, after returning to a normal diet, it is also likely to rebound.

　　 When I use the above 8 points to answer how to lose weight quickly, the other party is basically not satisfied, thinking that I am equivalent to saying nothing. But this is indeed the case, reducing body fat must be slow, because they must (except for surgical suction) be metabolized into carbon dioxide and exhaled from the lungs.
