80-year-old man's weight loss prescription is open
Summer is a season of honesty. I can't put on a down jacket to cover my beer belly, and I can't tell others, "It's not that my legs are thick, but I'm wearing long pants." Therefore, people's desire to lose weight is particularly strong in summer.

Recently, there was a WeChat article titled "80-year-old Chinese Medicine Doctor's Magic Weight Loss Prescription Open". According to the author,

? There is a prescription at home, which was handed down from generation to generation in the Tang Dynasty. There is no dragon liver and phoenix marrow in the prescription, but a proper amount of lotus leaf, poria cocos, Gynostemma pentaphyllum, hemp seed and hawthorn are added with 400 ml of water, boiled and simmered for 5 minutes. The effect of losing weight is very good. Some people can lose weight that day, some people lose 3-7 kg a week, and some people lose 10 kg for half a month. It is also very useful for people with old age and high blood lipid to lower blood pressure and reduce their stomachs. ?

After this article was published, it was quickly reprinted by many media, and many readers even "would rather believe it, not believe it, and turn it over first"; The drugs mentioned in the folk prescription are gradually out of shape, such as mulberry, oolong tea and lemon slices.

So, is the so-called weight loss remedy really that effective?

First, define obesity.

Obesity is clinically considered as a metabolic abnormality. The metabolic process of normal people is in a state of dynamic balance under the dual constraints of nervous system and endocrine system.

For example, the central nervous system controls people's hunger and appetite, and blood sugar level will stimulate insulin secretion, thus regulating the emptying rate of gastrointestinal tract and affecting satiety. The energy obtained from food is not only used for basic metabolism, physical labor, mental labor and other physiological processes, but also part of it becomes fat and is stored.

Comparison of subcutaneous fat between obese people with the same height and normal people

If patients consume too much energy from food because of genetic and social factors, such as the regulation failure of nervous system and endocrine system, but the energy is not enough, it will lead to excessive accumulation or abnormal distribution of body fat and weight gain.

Due to the differences of race and economic level in different countries and regions, there is no global unified diagnostic standard for obesity. Body mass index (BMI) is a commonly used index. According to "Guidelines for Prevention and Treatment of Overweight and Obesity in China (Trial)" in 2003, a body mass index greater than 24 is considered overweight, and a body mass index greater than 28 is called obesity.

(w refers to the weight in kilograms; H refers to the height, in meters)

In other words, if your body mass index is less than 24, there is absolutely no need to try drugs for beauty. It is probably more beneficial to adjust your posture through moderate activities.

Secondly, taking medicine to lose weight is not suitable for everyone.

For readers whose body mass index is greater than 24 and need to lose weight, we should follow the principle of easy before difficult.

Give priority to behavioral therapy, change eating habits and exercise habits, and achieve ideal weight through long-term adherence to a healthy lifestyle;

Secondly, we can consider consulting a dietitian, strictly controlling the total food intake, and making the energy metabolism of the human body in a negative balance through a low-calorie diet supplemented by appropriate physical activity and physical exercise. If the intake is less than the output, the weight will naturally be reduced;

If the above methods are ineffective, or obesity complicated with hyperglycemia, fatty liver and other diseases, drug treatment can be considered, but the doctor's advice should be carefully paid before drug treatment, and drugs should not be increased, decreased or replaced without authorization;

For severe obesity, those who meet the relevant indications and understand the potential risks such as surgical complications can consider surgical treatment.

A large-scale retrospective study in the United States shows that a low-calorie diet of 3~ 12 months can lose 8% weight on average, and the speed of 1 is enough to satisfy most people; There are also many related studies in China, and the results are similar. For example, Gao found that obese patients reduced their energy intake by 20% and exercised moderately. After three months, there were obvious differences in body mass index, waist circumference and other indicators. 2

Therefore, for readers, changing lifestyle is a healthy and effective way to lose weight without the help of traditional Chinese medicine.

Finally, the validity of the folk prescription is analyzed.

Lotus leaf, Poria cocos, Gynostemma pentaphyllum, Fructus Cannabis, and Fructus Crataegi, these drugs generally have evidence of lipid lowering, but their specific physiological functions are different.

For example, flavonoids contained in lotus leaves have obvious effects on reducing serum cholesterol and body weight in hyperlipidemia rats in the laboratory; three

Hawthorn also contains flavonoids, which significantly improves the protein level and antioxidant capacity of low density lipoprotein receptor in rats in animal experiments, suggesting that hawthorn has certain positive significance in preventing lipid metabolism disorder. four

However, the data in the laboratory cannot be copied to people. In these studies, they are qualitative, not quantitative. In the research process, it is often separated first, then purified, and finally administered by perfusion and injection. The concentration of drugs in experimental animals is far from "adding water" or "boiling".

The concentration of traditional Chinese medicine after boiling is much lower than that of experimental animals.

Hemp seed contains a lot of fatty oil. Animal experiments have proved that hemp seed water solution has an exciting effect on isolated rabbit intestine and can increase the peristalsis range and frequency of intestine, so hemp seed is often used to treat constipation in the elderly. five

Poria cocos is related to urinary regulation. Porphyrin in Poria cocos can activate sodium ions, potassium ions and related enzymes on cell membrane, indirectly activate diuretic mechanism, and compete with aldosterone for related receptors in vivo. Aldosterone belongs to the renin-angiotensin system, and its main physiological function is to enhance the reabsorption of water by the kidney, so Poria cocos has a certain diuretic effect. six

In other words, if these two drugs are taken too much, it is certain to lose weight, because they promote defecation and urination. But this kind of weight loss is water, not fat.

As for Gynostemma pentaphyllum, more attention is paid to its protective effect on the liver. seven

In short, don't have too much hope for these so-called folk remedies. You know, even after weight loss surgery, special emphasis is placed on diet control. Generally speaking, there is no obvious weight loss in a short time after operation (1 month), and it takes a long time (6 months ~ 1 year) to have a good effect. eight

It is best to set long-term goals according to your personal situation, and never blindly pursue speed. If you are eager to achieve success, too fast weight loss may lead to too fast decomposition of body fat, induce or aggravate inflammatory infiltration or fibrosis of the liver, increase the burden on the liver, and cause fatty liver and other diseases. nine

Truth: The weight-loss effect of "80-year-old doctor's magic weight-loss prescription" cannot be guaranteed. Simply taking medicine to lose weight is easy to rebound and has health risks.
