Some diet pills, tea, weight loss coffee and food all have the function of losing weight. The principle is to achieve the goal of losing weight by stimulating the central nervous system, reducing food intake and inhibiting diet. If the drug is used improperly, it will cause liver damage, endocrine disorders and other consequences. Hormone drugs promote human metabolism and protein decomposition, increase consumption and achieve the purpose of losing weight; And laxatives and diuretics forcibly expel normal body fluids by increasing excretion, rather than excess fat, which often leads to dehydration; Food to lose weight is mostly composed of indigestible plant fiber, which will make you feel full. After taking diet pills, people often think that what they lose is fat. In fact, their lost ingredients include water, fat and protein, some of which have obvious side effects or poor effects, accompanied by loose, rough skin and increased wrinkles. The body will quickly replenish the lost water, and if protein is subtracted, the muscle function will decline. When you stop taking these diet pills, fat will quickly accumulate (rebound), but the lost muscles have not recovered. Experts warned us that taking diet pills must be combined with diet and exercise to achieve the best weight loss effect. No matter what kind of diet pills, diet pills achieve the purpose of losing weight in the following three ways:

(1) Inhibit the appetite center of the brain, reduce appetite, make obese people not want to eat, and reduce their food intake. Reduce calorie intake.

(2) Stimulate metabolism, increase the body's oxygen consumption and the oxidation of fat and sugar, thus reducing the accumulation of fat in the body.

(3) Stimulate the intestine, thus reducing nutritional respiration and increasing excretion. Although taking diet pills, you can get a certain weight loss effect. However, some drugs have great side effects. Therefore, obese people should not blindly take medicine and reduce their intake. It is best to consult a doctor, find out the disease of obesity, and then choose drugs to lose weight, or other ways to lose weight. At present, there are many drugs to lose weight in the domestic market, including western medicine and Chinese medicine. These drugs usually fall into four categories:

Category I: appetite suppressants. There are mainly florfenicol, benomyl, fenfluramine and Jiangtangling.

The second category: increasing metabolic drugs. Mainly suitable for obesity complicated with respiratory insufficiency. Such as thyroid tablets and progesterone.

The third category: drugs that reduce nutrient absorption. Such as laxatives and cellulose preparations. The fourth category: Chinese medicine. Such as chubby girl, blood spirit, slimming granules, etc. The most commonly used diet pills mainly stimulate the hypothalamus and regulate appetite.

Among them, amphetamine (central stimulant) has the effect of inhibiting muscle hunger and appetite; There is also Fanfeilamine, which stimulates satiety and suppresses appetite. It should be pointed out that all the drugs we have been using contain highly metabolized thyroid hormone. Obese patients with complications are contraindicated. In short, when using drugs for treatment, you must listen to the doctor's advice and follow the doctor's advice. Never take some so-called "diet pills" casually.

You must go on a diet to lose weight while taking diet pills. Most diet pills only strengthen the effect of dieting and lose weight, and have no direct fat removal effect; The effect of losing weight comes directly from dieting, so dieting is the main means of losing weight, and diet pills are only auxiliary means; Those who take diet pills for a long time without dieting at the same time will not only lose weight, but also become psychologically dependent on drugs. It is difficult to stop taking medicine after addiction. If you don't continue dieting after stopping taking diet pills, you will soon gain weight again. Instead of taking diet pills, just dieting to lose weight will surely succeed. Although it takes a short time to achieve the weight loss goal, the weight loss effect is easier to maintain. Dieting and losing weight is a lifetime thing and cannot be interrupted. However, the longer the diet pills are used, the worse the efficacy of weight loss, and eventually they will fail. Buy diet pills only when necessary, and never use them all the year round.
