BMI is the abbreviation of Body Mass Index, which is currently an important standard commonly used internationally to measure the degree of obesity and healthiness of the human body, and is calculated by the formula of weight/height squared (international unit kg/㎡).

Under normal circumstances, the normal range of BMI is 18.5 to 24.0, when ≥24.0 and <28.0, it is overweight; and when ≥28. 0, it is obese; and when <18.5, it is too low. For example, a woman with a height of 1.6m and a weight of 60kg has a BMI of 60/(1.6×1.6)=23.437, which is a normal weight.

In addition to BMI, for the calculation of weight, we can also abdominal circumference, waist-hip ratio, etc. to calculate whether the weight is normal. Causes of overweight and obesity are numerous, common such as improper diet, long-term alcohol abuse, lack of exercise, etc., can lead to obesity, we should pay attention to, obesity can lead to a series of complications, in order to their own health, we should pay attention to the control of body weight, obese people pay attention to weight loss.

This issue, in fact, is currently the concern of many women, especially many young women, pay great attention to body maintenance. In fact, compared with the figure of good appearance, physical health is more important. Sometimes a lot of young women, in order to slim, a hard to lose weight, in fact, from the bmi value, standard weight is to reflect and measure the health of a person is one of the important signs. Being too fat or too thin is not conducive to health and does not give a sense of fitness.

So let's look at how much bmi is normal from the perspective of what's good for your health? Below we have replaced the BMI abbreviation with capital letters for a more formalized approach.

First, what is BMI?

BMI (Body Mass Index, or BMI for short), a figure obtained by dividing the weight in kilograms by the square of the height in meters, is a common international standard for measuring the degree of fatness and thinness of the human body, as well as whether it is healthy or not. It is not only used for women, but also for all people.

There are many different algorithms for BMI.which is dominated by international standard algorithms.

First, an internationally recognized algorithm:: The formula is.

Body Mass Index BMI = weight (kg)/height (m) squared i.e. kg/m2.

(Chinese Physical Fitness Standard: normal range 18.5-23.9, overweight 24.0-27.9, obese ≥28.0).

Secondly, there is also a simple algorithm of standardized weight for normal adults:

Standard weight (kg) = Height (cm) - 105

Third.There is also an ideal weight algorithm based on the differences between northern and southern Chinese.

Ideal weight for a northerner (kg) = [height (cm) - 150] x 0.6 + 50;

Ideal weight for a southerner (kg) = [height (cm) - 150] x 0.6 + 48.

In the second and third of these, after calculating the standard weight, use your own weight ÷ standard weight to get a value refer to the following values to see if your weight is normal.

① Plus or minus 10% of standard weight is considered normal weight.

② Standard weight plus or minus 10% to 20% is considered overweight or underweight.

③ Standard weight plus or minus 20 or more is considered obese or underweight.

Compared to BMI, body fat percentage testing is actually a better reference indicator at this time.

Body fat percentage is the proportion of body fat weight in the total body weight of a person, also known as body fat percentage, which reflects the amount of fat in a person's body.

Here are the female calculations only Body fat percentage formula for adult females:

Parameter a = waist circumference (cm) × 0.74

Number of participants b = weight (kg) x 0.082 + 34.89

Body fat weight (kg) = a - b

Body fat percentage = (total body fat weight ÷ body weight) x 100%

The normal range of body fat percentage for adult women is 20% to 25%. If the body fat percentage is too high and the weight exceeds more than 20% of the normal value, it can be considered as obese.

So for weight loss, the main reduction is fat, not just weight loss. Abdominal obesity in particular is detrimental to the body's aesthetics and health and requires efforts to lose weight.

For BMI, what are the effects if it is too low or too high? What should I do?

1、What are the hazards of having a low BMI? What to do?

Some female friends in order to reflect the devil body, deliberately lose weight, resulting in BMI below the normal value, in fact, is not good for health.

A low BMI will not only affect your daily life and work, but also make you feel tired easily, have poor physical strength, lower body resistance, poor immunity, weak cold resistance and disease resistance, and susceptible to a variety of diseases, such as gastroptosis, gallstones, and so on.

So you need to take proper nutrition and eat more desserts and meats as appropriate.

2、What are the dangers of a high BMI? What to do?

First of all if it is too high, it will affect the female figure.

In addition, if obesity occurs, it poses many risks, increasing the risk of cardiovascular disease, affecting the functioning of the digestive system, affecting the functioning of the endocrine system, increasing the risk of cancer, damage to the soft tissues of the joints, a decrease in the ability to reproduce, and so on.

Some data show that for every 2 increase in body mass index, the relative risk of coronary heart disease, stroke, and ischemic stroke increases by 15.4%, 6.1%, and 18.8%, respectively.

So what do you do with a high BMI?

1. Changing dietary habits

Diet appropriately, snack less, eat fewer high-fat foods, reduce calorie intake, and change your main diet to vegetables, fruits, grains, and small amounts of lean protein. Slow down the speed of eating and eat slower. And, don't drink carbonated beverages, sugar-sweetened beverages, dairy beverages, etc.

2, adhere to regular exercise

Aerobic exercise, such as brisk walking, calisthenics and other programs, no less than four times a week for about 60 minutes each time, is valuable.

3. Maintain an optimistic mindset

Adjust your mindset, especially don't eat and drink when you are bored or stressed.

4. Ensure adequate sleep

Get enough sleep and don't stay up late at night.

To summarize, bmi is an indicator for observing human body weight, and it is important to do a good job of testing it on a daily basis, as well as testing body fat, as both low and high values can be detrimental to the human body, and attention should be paid to improving it.

I am.@General Practice ChatIt's not easy to code, I hope it's helpful, thank you for your likes and concerns!

Hello, I'm May, now ready to reveal the answer to this question, if you have a special suggestion for the answer, welcome to leave a message in the comments section, agree with the lower right side of the point, like can be in the upper right side of the point of attention, my headline is the dietitian May sister. Women's BMI is normal is usually in the 19-24 period, the best is 20-21, but this value is only a rough calculation of whether the weight is overweight only. In fact, to determine obesity is not only look at this value, for example, some of the weight is very low, the BMI value is also very low, but the abdomen is very large, which also belongs to a kind of obesity. If your BMI value is within the normal range, should pay attention to from other ways to measure their own fat again, for example:

Measurement of subcutaneous fat。

This method is used for those who have normal weight but have flesh on their abdomen, it is used to grab the skin on both sides of the navel (either side) with the thumb and forefinger, measure its thickness to get this result and determine the amount of subcutaneous fat. If the thickness between the thumb and index finger is 2.5cm or less, it is normal. If it is greater than 2.5cm, it is obese; if it is greater than 5cm, it is overweight.

Determine the value of the waist-to-hip ratio.

This value reflects the normal ratio of waist and hips, and if this ratio is abnormal, it can also indicate obesity. When measuring, you need to stand up, use a ruler to measure the waist and hip circumference, and then compare the value of hip circumference with the value of waist circumference to get this number is called the waist-hip ratio, the upper limit of this value in men is 0.85-0.90; and women's value is 0.75-0.80.

Measure your body fat percentage.。

Obesity is also a symptom caused by excess fat, so we need to calculate whether the body fat content is actually excessive or not. This value can be measured by a body fat scale, or if you don't have a body fat scale, you can calculate it by hand. The formula for calculating body fat percentage is 1.2*BMI+0.23*age-10.8*gender-5.4, where the male gender coefficient is 1 and the female gender coefficient is 0. The normal range of body fat percentage for females is 18%-25%, while for males it is 12%-18%.

Personally, I think it is better to stay within the normal range, too high or too low is not good for the body. Women should not lose too much weight in order to pursue the so-called bone beauty, it is really unnecessary. Health is good.

thank you for your invitation

I think the bmi index is now most women pursue, and is required to beauty a standard, especially in the life of the woman to pay attention to, I think need to pay attention to a degree, need to pay attention to the science of looking at the index.

I've seen this bmi before at a weight loss organization, and after listening to them for a while, I think it's still very inspiring, for example, once we understand an index, we struggle to follow the healthy values of that index, and I think that's what a lot of women need to do, and desperately need to do.

My girlfriend in order to achieve the value of 19, every day to eat, exercise, sleep are very regular, and developed a very good routine, especially at night do not eat snacks, I was thinking that the value of the constraints on her, after understanding the bmi, but also for her own a reminder, from her, I think a person should pay more attention to is the rules of regular life is the most important.

That's why in order to have a good shape and a good body, you need to have a normal life, especially with self-discipline!

• What do you guys think you need to watch out for?

Body Mass Index (BMI) is the most commonly used international tool to measure the ratio of weight to height. It uses the ratio between height and weight to measure whether a person is too thin or too fat.

The Body Mass Index (BMI) is suitable for all persons from 18 to 65 years of age, except children, developing adolescents, pregnant women, lactating mothers, the elderly and the muscular. The formula is as follows:

Body Mass Index (BMI) = weight (kg)/height (m)^2 EX:75/1.8^2=23.15

Asian adults please use the following guidelines:

Body mass index category Chance of disease*

< 18.5 Underweight Increased prevalence of certain diseases and certain cancers

18.5-23.9 Normal

24-27.9 Overweight

>28 Obesity

*Diseases include type B diabetes, hyperglycemia, hyperinsulinism, hyperlipidemia, coronary heart disease, hypertension, cancer, and gout.

The formula can determine the health status of the human body. According to the relevant medical statistics in the United States: people with BMI less than 16 and people with BMI more than 30 have the highest mortality rate.

The lowest mortality rates were among those with a BMI between 20-22.

Some people think the best looking body shape BMI value is:

Women's BMI = 19 Men's BMI = 22

With this, the optimal weight can be projected based on height:

Weight of the most shapely lady = 19 χ height χ height

Weight of the most shapely man = 22 χ height χ height

Nowadays, with the high degree of economic development, people's standard of living has improved greatly, from the past of not having enough to eat and wear to the present can be a big fish and meat every meal. And high energy intake will bring a lot of health risks, one of the most important is obesity, obesity will induce high blood pressure, high blood fat, high blood sugar and other diseases, so we must pay attention to obesity. A person wants to evaluate their own obesity is the easiest way to calculate the BMI, through the BMI can be roughly understand their own is thin, normal weight or overweight or obesity, so that you can adjust the diet in time to prevent disease. In this article, we take you to understand the BMI, female BMI how much is normal, life and should pay attention to some of what. If you like this article, please like and forward support, thank you.

I. What is BMI

BMI, or BMI index, was first proposed by the Belgian genius Kettler in the mid-19th century, also known as Body Mass Index, or Body Mass Index for short. The English full name is Body Mass Index, referred to as BMI. BMI is an indicator closely related to the total amount of fat in the body, which can directly reflect the status of systemic overweight and obesity, and is an important indicator to measure whether obesity and standard weight.

The formula for calculating BMI is BMI=Weight (kg)/Height squared (m), for example, if someone is 1.7 meters tall and weighs 60 kilograms, his BMI should be 60/1.7^2=20.8. In addition to expanding the formula data for other indicators for readers:

Standard weight = (height cm-100) x 0.9 (kg);

Standard weight (female) = (height cm-100) x 0.9 (kg) - 2.5 (kg);

Normal weight: deviates from the standard weight (more or less) by about 10%;

Overweight: greater than 10% and less than 20% of standard body weight;

Mild obesity: greater than 20% of standard weight less than 30% of standard weight;

Moderate obesity: greater than 30% of standard weight less than 50% of standard weight;

Severe obesity: greater than 50% of standard weight.

II. Normal BMI values

The World Health Organization (WHO) defines BMI as 22 for men and 19 for women, and the normal range of BMI is 20 to 25 for men and 18 to 23 for women, below the lower limit is considered thin and above the upper limit is considered fat. Meanwhile, WHO defines overweight and obesity for adults as follows: overweight when BMI is equal to or greater than 25, and obesity when BMI is equal to or greater than 30. Our country divides the BMI value range according to the physical characteristics of our people: BMI less than 18.5 is underweight, between 18.5 and 23.9 is normal, between 24 and 27.9 is overweight, and greater than or equal to 28 is obese.

It should be noted that BMI is a neutral and reliable indicator when comparing and analyzing the health effects of a certain weight on people of different heights. However, BMI is not suitable for everyone, including athletes who are doing weight training, pregnant and breastfeeding women, and the frail or sedentary elderly.

III. Optimal BMI for women

The optimal BMI for women is usually around 18 to 22. Since there is a certain relationship between normal menstruation and body fat content in women, whether a woman is too thin or overly obese, it may lead to menstrual disorders and endocrine disorders. Therefore, if a woman's body mass index is not within the normal range, she needs to take appropriate treatment according to the situation.

In case of women who are underweight, they need to take proper protein supplements.

It is recommended that you gain weight by eating more protein-rich foods in your diet on a regular basis, such as milk, eggs, and soy products, as well as eating more fresh vegetables and fruits. Of course eat more meat is also a good way, but eat what meat as selective. Fatty meat will eat less, because such meat is too greasy, not good for the stomach. You can eat more fish, beef and chicken, these meats are nutritious and healthier, often eat can also increase the body's protein content, help the body to increase muscle. At the same time to develop good habits, go to bed on time every day, do not stay up late, to ensure adequate sleep, usually also want to exercise properly, improve their immunity.

If it is a woman who is too obese, then she needs to control her diet and strengthen her exercise to regulate it.

First, control your diet and reduce your calorie intake.This is achieved by eating fewer high-fat foods, while consuming foods with unsaturated fats is great for the heart and helps one to absorb fat-soluble vitamins. In addition, there are many sources of calories and eventually it will be stored as body fat, so in order to achieve calorie reduction, adjust your diet and keep your mouth shut.

Second, eat more fruits and vegetables as well as cereals.These foods are rich in vitamins and fiber, and fiber increases satiety.

Third, there should be a wide variety of food types every day.With expert advice and data from research findings, choosing different types of rich and varied foods on a daily basis can be very beneficial to your body.

Fourth, reduce your intake of sugary and alcoholic substances.Don't add extra sugar to your food, such as soda, white sugar. Alcohol is also a no-no because it reduces the rate at which the body burns fat by about 1/3, which means that body fat is more likely to accumulate than to be burned. This means that body fat is more likely to accumulate rather than be burned. And these foods are usually not very nutritious and provide ingredients that are not essential to the body, and can even be bad for your health.

Fifth, exercise properly.Exercise for at least 30 minutes a day at a moderate intensity. This will make you feel more energized and will also promote fat burning.

Sixth, have a positive and optimistic mindset.Adjust your mindset, set a realistic goal and focus on fitness. Be careful to take control of your body, don't overeat when you're bored or stressed, and only eat when you really need to.

Finally, to send you a sentence: short neck, thick neck, five short body, body fat, thick blood, latent harm, weight loss and lowering fat, can not wait; eat more fruits, eat more vegetables, prevention of thrombosis, infarction and cerebral blockage, the form of slim, all at ease.

Every time I will spend a lot of time to check the information, edit the article, although the article reading volume is not high, but I will still insist on it, even if I can help a friend, this is also considered a success, so I hope that you read this article friends can click a support, thank you!

thank you for your invitation

I'll talk about it.

I think need to pay attention to the science of maintaining their own body and health, bmi this value I also heard from the mouth of the ex-girlfriend, she that time to pay special attention to a value, but I think a person to maintain a good body need more than one indicator, do not think that is not fat, with a good waistline is healthy.

I personally feel that a person's perfection and health should be balanced and comprehensive, such as body shape, appearance, fat and thin and connotation cultivation and other factors of the indicators, of course, the woman is still thin good, because after the thin after you can casually wear clothes, in the dress can be a little bit casual, if the fat, wear clothes on the more elaborate. The fact is that the most important thing is to be able to get the best out of your life, and to be able to get the best out of your life, and to be able to get the best out of your life.

So I think it's just a numerical value and an indicator, he's binding and demanding of a person, and a standard, I guess, and I think what you should pay attention to is to be healthy and thin and healthy and stay in shape.

• What do you think?

First of all, I would like to say what is bmi, bmi is height to weight ratio, that is, weight / height squared, pay attention to the calculation here is the kilogram divided by the meter, generally speaking, bmi 19-24 are normal, but a girl concerned about bmi, is bound to have a certain requirement for bodybuilding body, and this standard is actually more corresponding to the white man, white people have big bones, fat more plump, on the The aesthetics of the body is very different from that of the Orientals. Take bmi24 for example, we simply calculate, if a 1.65 meters tall girl, bmi reached 24, then his weight up to 65.34 kg, that is, 130 pounds, for a Chinese woman is obviously on the heavy side.

So the standard bmi of Asian Mongolian women should be how much, usually we prefer girls will bmi control in 20 or so, which is in line with the Chinese aesthetic of the slim figure, give the following table for reference, the corresponding height, to achieve the corresponding weight, the figure is more perfect.

To maintain a standard figure, in fact, there is no other way but to eat less and move more. Of course individual differences exist, everyone's metabolism is different, the absorption and storage capacity of food are different, there are indeed some eat more not fat gifted people, but for most people, self-discipline life is the only means of figure management. There is a good saying that fitness is the only thing that can definitely be achieved through hard work, so if you have to ask what to pay attention to, first of all, please pay attention to the four words, self-discipline, persistence.

Aerobic exercise is a fat-consuming tool, jogging, elliptical machine, swimming, boxing and other sports can be very good to help control the figure. Diet, rice flour, sugar and other carbohydrates must be controlled, while protein intake can be increased appropriately, but not overeating, even if the chicken breast, but also energy, eat more will still grow meat Oh. High-fiber plant vegetables, a sense of satiety, and provide a wealth of vitamins, is a good choice for the fitness crowd!

Straight to the point!

Before answering this question, there are a lot of sisters out there who may not be quite sure what BMI means! So, let's start with what BMI means!

BMI is actually a method of calculating body fat percentage, collectively known as the BMI calculation method! Next, I will share the formula of the BMI calculation method with you, and if you are interested, you can calculate your own body fat percentage!

BMI formula.

①BMI=Weight (kg)÷(Height×Height)(m)

②Body fat percentage: 1.2×BMI+0.23×age-5.4-10.8×gender (1 for male, 0 for female)

Above, it is the way of calculation, and below, I come to give you about women's body fat rate in terms of the problem:Normal adult female body fat rate is generally in the 25% ~ 28%. Body fat rate should be kept in the normal range. If the body fat rate is too high, weight more than 20% of the normal value can be regarded as obese. Obesity indicates insufficient exercise, overnutrition or some kind of endocrine system diseases, and often complicate hypertension, hyperlipidemia, atherosclerosis, coronary heart disease, diabetes, cholecystitis and other diseases; if the body fat rate is too low, lower than the safety of the lower limit of the body fat content, both women 13% ~ 15%, may cause dysfunction.

Finally, I'm going to tell you about the most important concern of all the girls, the change in appearance brought about by the body fat percentage!

visual effect

Body fat percentage body shape characteristics in women:

8%~10% Athletic status achieved by a very small number of female athletes (can cause amenorrhea, menstrual disorders and breast reduction)

11%~13% Dorsal muscles are visible, and the external abdominal obliques are more distinctly compartmentalized (female bodybuilders' competitive status)

14%~16% The dorsal muscles are visible and the abdominal muscle compartmentalization is more pronounced.

17% to 25% is the ideal type of body fat percentage for women.

17% to 19% Fat is not flabby in all parts of the body, and abdominal muscle compartmentalization is evident.

20% to 22% Fat is not flabby in all parts of the body, and the abdominal muscles are beginning to show, and the compartmentalization is not obvious.

23% to 25% of the body fat in all parts of the body is basically not flabby and the abdominal muscles are not visible.

26%~28% All parts of the body fat on the waist and abdomen obviously flaccid, abdominal muscles do not show.

29%~31% Abdominal muscles are not visible and waist circumference is usually 81~85 cm.

32%~34% Abdominal muscles are not visible and waist circumference is usually 86~90 cm.

35%~37% Abdominal muscles are not visible and waist circumference is usually 91~95 cm.

38%~40% Abdominal muscles are not visible and waist circumference is usually 96~100 cm.

41% or more Abdominal muscles are not visible and waist circumference is usually 101 centimeters or more.

Well, the above, that is, I share with you a little bit about women's body fat rate of some of the small knowledge, I hope to help you, and finally attached a table of women's body fat rate when the body, come to see how much body fat rate is your ideal body!

Let's wish all of you sisters the best of luck in your endeavors to have a body that you are happy with a healthy body fat percentage!
