1. Diuretics (urine), laxatives (feces), saunas or wearing plastic clothes (sweating) can all lose weight immediately. This kind of water loss will damage body functions, such as decreased immunity, fatigue, listlessness and so on. And "rebound" (weight recovery) is easier. Most slimming teas contain laxatives such as rhubarb and senna.
2. Hunger (if all foods are reduced by more than 1/3) and disguised hunger (if you don't eat staple food, eat vegetables and meat) will first cause glycogen and protein in muscles to decompose (supply energy) and take away water in muscles (2-4 times the weight of glycogen and protein). Generally, the weight will drop within 2 or 3 years, and the more muscles, the more obvious the effect. Muscle breakdown will weaken physical strength and immunity. Unless you persist for a long time, it is easy to rebound. Long-term persistence may lead to nutritional deficiency, anemia and amenorrhea.
3. Catgut embedding, acupuncture, acupuncture weight loss, massage, etc. Most people practice the so-called diet, that is, hunger in disguise. The principle is the same as above, and it can also make people lose weight in a week.
4. Taking metformin (oral hypoglycemic agent, used for diabetes treatment, prescription drug) can suppress appetite, reduce energy metabolism efficiency, and reduce muscle weight, and (when the dose is large) can make the weight drop within one or two weeks. However, metformin does not affect fat accumulation, with limited weight loss effect and many side effects. Although some doctors take metformin to lose weight themselves, it is illegal to give patients metformin to lose weight.
5. Taking thyroid hormone (Eupatorium adenophorum) can improve basal metabolism (similar to hyperthyroidism), increase energy consumption, accelerate fat burning, and lose weight within one or two weeks. Hormones have many side effects, and it is illegal to use thyroid hormones to lose weight at present.
6. At present, there are only "Orlistat" (Sanico, Imanin, etc. ) is a legal diet drug, which can inhibit the absorption of fat in the intestine and make some fat in food flow out of the anus (feces), that is to say, a good meal is "eaten for nothing". It usually takes weeks or months (depending on how much fat you ate initially) to lose weight. Because this diet drug mainly acts on intestinal fat, with little side effects, it is suitable for eating with delicious meals, but it is ineffective for obese people with a light diet (eating less fat).
7. Sibutramine (Qumei, Aoquqing, etc. ), which was very popular a few years ago, is now banned. They work by suppressing appetite and eating less. The speed of losing weight varies from person to person, some fast and some slow. Although it has been banned because of heart side effects, it has been quietly added by some weight loss products and health care products, and the ban continues. Sometimes, metformin is also illegally "adopted" by these products.
8. Liposuction surgery, directly sucking out local subcutaneous fat and tissue fluid, can immediately lose weight (it will be effective when you come down from the operating table, almost as fast as amputation). There are certain risks in surgery, and there is still the possibility of rebound. Although it is difficult to accumulate fat at the suction site (because fat cells have been pumped away, it is another matter if they are not all pumped away), it is still possible to accumulate fat around or in other parts.
