Ten years ago, as an older student, I would never have imagined that one day in the future I would pay attention to the topic of weight loss. To tell everyone, my wish at that time was actually... I hope I can get fatter.

Okay, so it’s true that it hurts, but it’s the feeling that the ribs are too thin when sleeping. Small belly? Beer belly? No one has ever heard of it! The BMI value is 18.3, the standard is thin, and the typical "walking clothes support".

BMI , body mass index, body mass index, formula: strong1 _strong4 span2 body weight. Among them, the unit of weight is kg and the unit of height is m. What is yours? However, BMI is only one of the indicators, and more indicators such as body fat percentage should also be paid attention to.

In order to realize my desire to gain more weight (I will punish myself with a slap in respect),Whenever you go to the cafeteria to have a meal, you must first clear your throat, then lean over and tilt your head slightly, and then say to the aunt behind the glass window: "Auntie, please add more rice!" The loudness of the sound must be controlled properly. If it is small, I am afraid that my aunt will not hear it, and if it is large, I am afraid that it will be heard by the students behind.

Perhaps it is because the weather in the north is too cold and the body consumes a lot of calories. After 4 years of university, I have accumulated more than 200 credits, but my weight has not grown. In a word, the university fattening plan failed!

365 days a year and half a year is summer in Guangzhou, where the food on the school dinner plate has changed from chicken stewed with mushrooms pork stewed vermicelli to steamed fish with white chopped chicken and boiled vegetables.

However, changes in climate and diet have not changed my weight, and my BMI is basically the same as four years of university. Well, it hurts to press on the ribs when turning over. It seems that it has to be solved by adding a mattress.

did not start life until the ninth-night and six-day transfer plan. However, it is the kind that is a bit off guard.

As the saying goes, time is to kill a pig.Fatty grows when you start to work. Good guy, I have been working for less than two years and my salary has not increased much, but my weight has increased. The former "clothes support", this time is really the rhythm of breaking the clothes directly, the clothes and pants in the closet all feel one size smaller, and you can clearly feel the "fitness" that you have never had before when you wear it on the body. It’s a pity to throw away good clothes. Don’t throw them away, wear them and you can’t wear them, and they occupy the cabinet. Tangled!

is like Shenzhen's deep stock exchange, and the weight goes up all the way. In the hot summer, the temperature remained high, and the BMI once soared from 18.3 to 26.3! At this time, it is not only the clothes in the closet that are tangled, but also the discomforts of the body that come with it.

"Strong talk about sorrow" and the feeling of "being in the blessing but not knowing the blessing". From that moment on, I began to miss the “walking clothes support” appearance, that kind of light feeling when I walked like “wind on the soles of my feet”!

p _p5 fat?

First of all, often sits sedentary . Except for eating and going to the bathroom, sitting for almost all day, lack of physical exercise, you think about it. In the capillaries of the human body, there is a substance called "lipoprotein lipase" , it is the main force involved in the fat metabolism process, will lose its activity by sitting for a long time , Resulting in fat can not be effectively broken down, causing obesity.

Secondly, after work, all kinds of entertainment are indispensable. Outside restaurants like to use heavy flavors to attract more customers, usually heavy oil heavy sugar , which leads to further accumulation of body fat.

In addition, modern work and life are fast-paced and social pressure is high, resulting in often staying up late or emotional changes , which can also easily lead to obesity.

is obviously not fat, why is there a small belly?

Many people will wonder,Obviously slender limbs, why God wants to give yourself a small belly?

It is generally believed that men's waist circumference is greater than 90cm, and women's waist circumference is greater than 85cm, which is considered as abdominal obesity . Quickly measure it~

The reason for this "central obesity" is that the human body's center of gravity is located in the waist and abdomen. In order to keep the body's center of gravity unchanged, is not at . If the body is out of balance, the best destination for excess fat is of course the center of gravity of the body.

Just imagine, if too much fat accumulates in the limbs, will it obviously affect the body's athletic ability ? This is the result of evolution. Millions of years ago, human beings lived in primitive jungles. Without the agile athletic ability, it would be a problem to escape in the event of an attack by birds or beasts.

Moreover, this phenomenon is also very common in other mammals. For example, the following fat friend.

In addition, our body structure also laid a solid foundation for this "central obesity". In the human body, there are two substances, insulin and glucagon.When the body consumes too much carbohydrate food, insulin will appear immediately and help convert blood sugar into fat.

The problem is here, insulin is too high, glucagon will increase blood sugar to reduce fat balance _strong4 and strong4 and can maintain the dynamic balance of blood sugar.
