As the saying goes, "a fat one destroys everything", which is not a joke. Overweight and obesity bring many major and chronic diseases such as hypertension, hyperlipidemia, diabetes, cardiovascular and cerebrovascular diseases and cancer.

　　Where is the most dangerous place to grow fat? Which provinces in China have the most "fat people"? Men are generally fatter than women?

　　China obesity map released in 2023:

　　These three provinces have the most "fat people"!

　　On August 17th, the team of Professor Mu Yiming from the First Medical Center of PLA General Hospital published a report entitled "Obesity Prevalence and Related Complications in China: A Cross-sectional Real World Study of 15.8 million Adults" in Diabetes, Obesity and Metabolism. The report draws a digital version of the "obesity map of China". The report data shows that the overall overweight population accounts for 34.8% and the obese population accounts for 14.1%. ①

　　This is the largest contemporary study on the prevalence of overweight and obesity and related complications in China so far, with 15.8 million eligible adults from 243 cities across the country participating.

　　1. Inner Mongolia, Shandong and Hebei have the most "fat people".

　　The proportion of overweight/obesity in the north is generally higher than that in the south, among which the top three provinces are Inner Mongolia (37.1%), Shandong (37.1%) and Hebei (36.6%).

　　2. Men are generally fatter than women.

　　Overweight and obesity are more common among men than women. The proportion of overweight among men is 41.1%, while that of women is 27.7%. The proportion of obesity among men is 18.2%, while that of women is 9.4%.

　　3. Fat people have a higher prevalence of various complications.

　　Compared with normal BMI, overweight/obese people have a higher incidence of complications. The most common complications among overweight/obese participants are fatty liver, prediabetes, dyslipidemia and hypertension. The higher BMI, the more complications.

　　Why are men fatter than women?

　　The reason is deeply rooted.

　　Why are men fatter than women? Wu Xueyan, chief physician of Endocrinology Department of Peking Union Medical College Hospital, said in an interview with People’s Daily Health Client that there are several reasons why men are more likely to be obese, which are usually related to their stress and emotions in life or work.

　　First, long-term high pressure and bad mood can easily lead to endocrine hormone secretion disorder. The main reason is that the secretion of stress hormone-adrenal glucocorticoids is greatly increased, which plays an anti-insulin role and increases abdominal fat accumulation, causing abdominal obesity characterized by "general belly".

　　Second, in order to relieve stress and release emotions, men often take unhealthy lifestyles such as drinking and eating too much as a means. In addition to overeating, alcohol often produces a lot of calories, which will also promote the formation of obesity.

　　The third is sleep problems. Long-term insufficient or irregular sleep can also lead to male obesity by breaking the energy balance. ②

　　Health times chart

　　In addition, from the "age difference" of obesity, the proportion of overweight and obesity is different between men and women of different ages, and the "peak age of obesity" of men is usually smaller than that of women. The prevalence of overweight in men peaked at 50-54 years old (unchanged at 55-59 years old), while in women it peaked at 65-69 years old. The prevalence of obesity in men reaches its peak at the age of 35-39, while that in women is 70-74.

　　In other words, men reach the peak of obesity at a young age (35-39 years old) because of the pressure of work and life and unhealthy lifestyle; Women do not reach the peak of obesity until they are 70-74 years old. Male compatriots, my heart is tied …

　　It is most dangerous to grow fat in this place!

　　When fat (fat) grows on our faces, arms, thighs … these visible places, it is actually not terrible. What’s really scary is that fat grows in places we can’t see or touch, which is more harmful to health and even brings fatal risks!

　　Body fat can be divided into two categories:

　　The first category is "visible fat", that is, subcutaneous fat. They are attached to the skin and have the function of helping the human body keep warm. But if we accumulate too much, it will become the culprit that makes us look fat.

　　The second type of "invisible fat" is visceral fat. They wrap and fill our internal organs, such as liver, pancreas, stomach and intestines.

　　In an interview with Health Times in 2022, zhaojie, a resident in the Department of Endocrinology, Yunnan Provincial Hospital of Traditional Chinese Medicine, pointed out that normal visceral fat can protect the internal organs and prevent them from being damaged when falling, but too thick visceral fat can lead to fatty heart and fat.
Liver, fat kidney, fat pancreas and other organs have abnormal functions. This kind of obesity is central obesity (abdominal obesity, visceral obesity).

　　Judging visceral fat is not only based on BMI (weight/height 2), but also on waist circumference, waist-hip ratio (waist/hip circumference) and visceral fat detection. For example:

　　▼ Men’s waist circumference exceeds 90 cm and women’s waist circumference exceeds 85 cm. Even if BMI is normal, the risk of illness will increase;

　　▼ The waist-hip ratio of men is greater than 0.9 and that of women is greater than 0.8, indicating that it is a high-risk group with excess visceral fat, and abdominal obesity is greater than 1.0. ③

　　Four ways to help you lose visceral fat

　　In an interview with Health Times, Dr. zhaojie gave four ways to lose visceral fat. ③

　　Exercise for at least half an hour every day.

　　People with excessive visceral fat need to exercise for half an hour to an hour every day, such as running, walking, swimming, cycling, etc. Ball games help to decompose fat while consuming energy. Even if there is no abdominal obesity, you can take more exercise to prevent problems before they happen.

　　2. Remember a ratio of 5:3:2 when eating.

　　Eating too many staple foods such as rice and bread is easy to accumulate visceral fat in the abdominal cavity, but you can’t stop eating it completely to avoid the brain’s inability to concentrate when you eat zero.

　　For example, for women with abdominal obesity, the daily staple food intake is no more than 100 grams, and the ratio of three meals is 5:3:2.

　　3. Limit calorie intake according to exercise

　　If you don’t have much activity at ordinary times, the calorie intake (kilocalories) should not exceed the body weight (kilograms) x 25; If you exercise regularly and have a large amount of activity, the calorie intake (kilocalories) should not exceed the body weight (kg) x35.

　　4. Increase the daily intake of cellulose.

　　If you want to lose weight successfully, you can’t lack cellulose. You can choose foods rich in cellulose such as oats, mung beans, tomatoes and grapefruit every day, which will help smooth excretion and promote metabolism.

Friends who have cars know that, generally speaking, 95 # gasoline will be a little more expensive than 92 # gasoline. Some car owners will subconsciously feel that it must be more expensive gasoline. Is 95 gasoline really better than 92 gasoline? What is the difference between them? Do you really know?

Is 95 oil purer than 92 oil?

There are rumors on the Internet that the higher the gasoline label, the better the quality of gasoline.

That was not the case.

In fact, the base oil of 92 # gasoline and 95 # gasoline is the same, but different additives are used to make them have different antiknock properties, which has nothing to do with the quality of gasoline itself. It does not mean that the higher the label, the less impurities there are, and there is no saying that the higher the label, the more fuel-efficient it is.

The biggest difference between No.92 and No.95 gasoline: anti-explosion.

What distinguishes 92 # gasoline from 95 # gasoline is actually the ratio of isooctane to n-heptane. 92 # gasoline is rich in 92% isooctane and 8% n-heptane. No.95 gasoline is rich in 95% isooctane and 5% n-heptane.

When the cylinder in the automobile engine is in piston motion, gasoline and air will be mixed and compressed in the cylinder. If the pressure in the cylinder is too high, it is easy to knock. The antiknock substance in gasoline is isooctane. The higher the label, the higher the isooctane content, and of course the stronger the antiknock performance.

The engine of a good car generally has a high power and compression ratio, and it is undoubtedly easy to knock when adding 92 # gasoline, which is why the better the car, the higher the requirement for gasoline label.

Can different grades of gasoline be mixed?

Last time, the Shaker saw a news on the Internet. When a Bentley owner went to the gas station to refuel, he saw that the oiler added 98 to 95 by mistake. He was so angry that he rushed up on the spot and gave the oiler a fat beating. Seeing this, someone should be tempted to ask: Is it really so serious to add the wrong oil?

If you originally added 92% oil, you accidentally added 95, which actually doesn’t matter; If a car that was originally fueled with 95 # gasoline was mistakenly fueled with 92 # gasoline, the problem is not very serious once or twice. However, if it is mistakenly fueled or mixed for a long time, the pressure in the cylinder of the car will not meet the requirements of the combustion of the oil-gas mixture, which will easily lead to knocking. In addition, it will also lead to an increase in engine carbon deposition, an increase in fuel consumption, and a knock on the cylinder, which will affect the life of the engine.

Since gasoline should not be mixed, what should we do? In fact, just add gasoline in strict accordance with the label requirements posted on the tank cover. This is not wrong. There is not much need to spend more money to add high-grade oil (of course, you don’t care about the better money), and you can’t add low-grade oil to save money!

Have you ever filled the wrong tank?
