As a medical professional, seeing the exaggerated propaganda about the efficacy of weight loss on the Internet, I want to stand up and make a popular science about the choice of weight loss medicine for everyone. Weight loss pills – according to the rigorous academic statement, it should be an anti-obesity drug. Obesity is now classified as an endocrine disease. You need to understand the ingredients of diet pills. I hope that after reading my article, it will attract great attention. Lose weight carefully.
- What kind of people need to lose weight.
First of all, it is necessary to clarify an important concept – body mass index, this index is a measure of whether you are obese, overweight, or normal. The most rigorous calculation method is: BMI = body weight / body surface area (body weight in kilograms, body surface area in square meters). Due to the difficulty in measuring body surface area, take an approximation: approximate body surface area = height squared (height in meters) Therefore, approximate body mass index = weight/height squared (weight in kilograms, height in meters) Unit) The international unified standard, BMI above 24 is overweight, and above 28 is obese. Some experts suggest that Asians may be lower, but the statement is somewhat inconsistent. I still use international standards. If your BMI is below 24, then you don’t need to lose weight at all, just keep it up.
- Ways to lose weight
In layman’s terms, there are five general methods of losing weight – exercise, dieting, taking medicine (including medicines and health products), physical therapy (including some medical devices for weight loss), and liposuction. Exercise and dieting are the most important ways to lose weight. All medicines and health products must be combined with exercise to produce good results. Medicines and health products for weight loss will be discussed in detail below. Physiotherapy – including some acupuncture, massage, medical equipment and other things that are currently used (I don’t know if I sum it up correctly, let’s talk about it for the time being). According to the experience of a cousin of mine, the weight loss service in some beauty salons is effective, but the price is very expensive. As for medical equipment, I don’t believe it. The management of medical equipment in China is really chaotic. Another cousin used a fat exercise machine that was very popular in advertisements and found it ineffective. It should be invalid in medical theory, and I won’t say much here. Liposuction – as everyone on earth knows – some people find it scary. This is used by people who are overweight, and the effect is really good.
- Active ingredients of medicines or health products with weight loss effect
(1) Sibutramine (trade name of Taiji Group’s product, Qumei, seems to be produced by a company in Jiangsu, I forgot the name), by inhibiting the re-collection of some hormones in the body (not written in detail, it is estimated that everyone does not understand) It leads to the user’s feeling of satiety and reduces food intake for the purpose of losing weight. This thing has been illegally advertised a lot in China, and there are serious safety problems. The adverse reactions it can cause include headache, constipation, high blood pressure and heartbeat. Accelerate, according to statistics around the world, more than 50 patients have died of heart disease caused by taking the drug, which has been hyped for a period of time.
(2) Fenfluramine and dexfenfluramine – are indeed widely used for a period of time, and the effect is also good, but the safety problem is extremely serious, causing serious damage to the heart valve, the management department is strictly prohibited in health food add this ingredient.
(3) Thyroxine – the endogenous hormone secreted by the human thyroid gland, how effective it is, you can see how it works. People who have hyperthyroidism will know (hyperthyroidism is excessive secretion of thyroxine), but this also has safety issues, too much is hyperthyroidism Symptoms; and the concentration of all hormones in the blood has a feedback regulation effect on the human body’s hormone regulation center – the pituitary gland, if you have more thyroxine in your body, the pituitary gland receives a signal to reduce the secretion of thyrotropin, thyrotropin If the secretion is reduced, the function of the thyroid gland will be reduced, and if you stop the drug suddenly, it will lead to “hypothyroidism”.
(4) Metformin, a commonly used hypoglycemic drug, is the drug of choice for obese diabetics. It does not cause hypoglycemia like insulin. Its mechanism of action is similar to that of L-carnitine, except that it promotes anaerobic respiration a little more. , may cause lactic acidosis. Safety issues are some gastrointestinal adverse reactions and liver function damage.
(5) Chitin, a polysaccharide substance extracted from the price of Arthropoda Crustacea (commonly speaking, animals such as crabs and shrimps), I will not say much about the mechanism of action. Anyway, it can reduce sugar, The absorption of fat, sodium ions, etc., has the effect of lowering blood lipids, blood pressure, and blood sugar. Now they are all used as additives in health food, not as medicines.
(6) L-carnitine (L-carnitine, vitamin BT), which consumes sugar by increasing mitochondrial respiration in cells. It is a relatively safe ingredient. The US FDA does not set a maximum dosage limit. The recommended daily dosage is 1 to 4 grams. As a health food additive for weight loss, it is used as a medicine in China, but the indication is not weight loss (vitamin BT tablets, non-prescription drugs, specification 0.1 g, used for abdominal distension, belching, nausea and heartburn caused by digestive disorders, including senile, pregnancy and indigestion in children). There is a product called “Newwaycom – Thin Ermei” which mainly contains this. The ingredients mentioned above are not necessarily exhaustive, but basically enough. Generally speaking, only orlistat and sibutramine are used as medicines in the world. The legal health food additives are crustaceans. Fenfluramine and thyroxine are illegal additives.
Finally, I will teach you to introduce an ideal weight loss product “Nuweikang-Shouermei”. This product is imported from Canada and mainly contains two safe weight loss ingredients, “chitin” and “L-carnitine”. The weight loss effect is ideal. Because it is an essential substance to supplement the body’s fat metabolism, after supplementation, the body’s fat metabolism will be normal, and it will not be easy to cause fat accumulation in the future, and it will not be easy to rebound.
