As for the weight, it is not good to determine the weight directly according to the specific weight because of the great difference in body shape. In order to better describe the weight, the following terms are used for further explanation.
The first is the standard weight. The so-called standard weight is the approximate range of weight at all ages calculated according to people's age and height. The commonly used formula is: male standard weight (kg)= height (cm)-105; Female standard weight (kg)= height (cm)- 100. Standard weight plus or minus 10% is normal weight, plus or minus 10% ~ 20% is overweight or underweight, plus or minus 20% is obese or underweight.
Now the most commonly used is the body mass index. That is, the number obtained by dividing the weight in kilograms by the square of the height in meters can fairly reflect the relative weight standard of people with different heights. The reference standard of China is 18.5 ~ 23.9, where 24 or above is overweight, 27 or above is obese and 40 or above is overweight.
In addition, body fat rate and waist-hip ratio are new reference standards, and obesity should be defined mainly for different body types. It is mainly to exclude the phenomenon that a certain part is particularly prominent and leads to weight gain, such as the beer belly crowd. Body fat percentage refers to the proportion of body fat weight in the whole body weight, also known as body fat percentage, which reflects the body fat content. Body fat rate is an important indicator of whether you gain weight or not. Waist-hip ratio is the ratio of waist circumference to hip circumference, which is an important index to judge central obesity. The body fat rate of normal adults is 15%~ 18% for men and 25%~28% for women. Reference value of waist-hip ratio: the average value of Asian males is 0.8 1, and the average value of Asian females is 0.73.
Normal weight is not only weight, but also closely related to age, height, body shape, fat distribution and other reasons. According to their own actual situation and a variety of weight reference standards for comprehensive analysis. However, for overweight patients, losing weight should be the most important thing.
Actually, weight has nothing to do with age. Generally speaking, there are two main ways for us to know our nutritional status, both of which are in the form of substituting into formulas, which are simple and clear, as follows:
Formula 1: weight = height (cm)-100× 0.9;
The weight calculated by this formula is the standard weight of this height. For example, your current height and weight is 165cm, then the standard weight calculated by substituting this formula is165 (cm)-100× 0.9 = 58.5kg, which means that the standard weight of a person with height 165cm should be 55.
We call your calculation the actual weight. When the actual weight is within the range of 10% of the standard weight, it is normal weight; When the actual weight is less than 10 ~ 20% of the standard weight, it is emaciation; When the actual weight exceeds 10 ~ 20% of the standard weight, it is overweight; When it reaches more than 20%, it is obesity.
Formula 2: Body mass index (BMI) = weight (kg)/height? (㎡);
You can get your body mass index by substituting your current height and weight into the formula. Under normal circumstances, our standard body mass index should be between 18.5 and 22.6. When the body mass index is less than 18.5, it is emaciated, when the body mass index is greater than 23, it is overweight, and when it exceeds 25, it is obese.
First, weight is not judged by age. If we use the most widely used body mass index to judge, it is mainly related to height and weight. Let me explain to you what the body mass index is.
Body Mass Index, also known as body mass index, is called body mass index in English, so it is abbreviated as body mass index after removing the initial capital. The calculation method is as follows: use the square of weight kg ÷ height (m), and the formula is as follows: body mass index (BMI) = weight (kg) ÷ height 2 (m).
It is the most common standard to measure body fat and thin in the world. This is why everyone's physical examination report will have a data, that is, the body mass index.
So how do we judge whether we are overweight or not? For example, a 40-year-old woman, height 1.6 meters, weight.
70 kg, then her body mass index is 27.34, then she is overweight.
The following are China's criteria for judging obesity by body mass index:
Too light: less than 18.5
Normal: 18.5-23.9
Obesity: 24-27.9
Obesity: over 28 years old
In short, if the body mass index is used to measure weight, it has nothing to do with age, but mainly with height and weight.
We look at a person's weight, not just from a weight to judge whether it is normal, but from the perspective of height. Because each of us is different in height, what does the same weight 150 kg mean to women with height 140 and women with height 170?
We judge whether a person is overweight or underweight. The most commonly used index is body mass index, which is what we call body mass index. The calculation method is to divide the kilograms of weight by the square of height meters, and the value obtained is your body mass index.
According to our body mass index standard in China, those below 18.5 are underweight, those between 18.5-26 are normal, and those above 24 are judged overweight.
There is a simpler calculation method, that is, the standard weight is the centimeter of height minus 105. If your height is 165, then your standard weight is 165- 105, that is, 60㎏ and 120 kg.
In general, it is better for us to control our weight within the standard range as much as possible. If we are underweight, we may have problems such as malnutrition. Being overweight is obesity, and obesity will bring multiple risks such as hypertension and diabetes.
For middle-aged and elderly women, weight control is equally important. Maintaining a healthy lifestyle, a balanced diet and exercise can not only keep you away from diseases, but also make you more radiant!
Ladies, doctors are your best friends!
I am Luo Chengyu, director of the Surgical Breast Center of Fuxing Hospital of Capital Medical University. I am serious about being a doctor, doing popular science with my heart, and making friends sincerely. I am willing to be your best "male best friend" all my life!
Ladies who love beauty are obsessed with their figure and weight, and even step on electronic scales every day for a long time in order to gain a little meat. So, what kind of weight is appropriate for a 40-year-old woman? Today, Dr. Luo will come to talk to you!
1, from a popular saying.
There is a saying in society that what kind of woman cares most about her weight?
The answer is incredible: a woman weighing about 100 kg.
So what causes women who shouldn't care too much about weight, but care most about losing weight? In fact, the answer is easy to understand. /kloc-women over 0/30 either gave up or gave up after many times. And about 90 pounds, of course, I won't worry about obesity.
2. Do you really need to lose weight?
Strictly speaking, women's weight loss is not a medical problem, as long as you are not pathological obesity, or obesity has seriously exceeded the standard, or has seriously affected your life and psychology. Unless these circumstances, as long as you are happy inside, this weight is appropriate.
Many health experts hold various calculation methods and teach women how to measure their obesity. Even take the standards of western countries to measure the obesity index of oriental women.
Well, there is a certain scientific basis, but I personally suggest that you just understand it.
1, life is not a matter of weight, do you have to struggle with a few pounds?
As I said before, as long as obesity is not pathological and does not affect your life and psychology, then micro-obesity and micro-obesity are not too harmful to your health.
2, different body types, different races, different heights, and different judgments on weight.
This is a well-understood question. Overweight or obesity of women is sometimes not a personal problem such as diet, but is influenced by some factors that cannot be changed or difficult to change.
For example, sometimes we will say that a person belongs to a big skeleton, and such a person's skeleton is bigger than the average person, so the same height and weight will be bigger; There are also ethnic factors, height and other influences.
Therefore, weight cannot be generalized, nor can it be solved by a formula.
The popular saying is body mass index, that is, body mass index. Its calculation method is: the square of weight (kg) ÷ height (m).
It must be admitted that this index has certain reference significance. I suggest you keep it in mind as an understanding of your obesity and weight in daily life.
However, we can't just use this index to measure and judge. The index has the elasticity of the upper and lower range, and it cannot be depressed or even entangled every day because it exceeds it.
Many women lose weight because they are a little fat, and there are many ways; If the method is scientific and healthy, such as going to the obesity department of a hospital for scientific guidance, then it must be adhered to under the advice of a doctor.
Moreover, there is a mentality that we should pay attention to results, but we should pay more attention to the process; For example, you lose weight by running and controlling your diet. Instead of focusing on your weight.
To sum up: the above statement is just my personal opinion. Weight should be controlled. If obesity affects life and health, it must be treated. But pay attention to your weight, and if you are in a good mood and good mood, if the process makes you unhappy or even brings physical and mental illness, why?
Welcome to pay attention to women's health with me!
