Overweight: BMI = 25-30
Mild obesity: body mass index >; 30
Moderate obesity: body mass index >; 35
Severe obesity: body mass index >; 40
Guiding opinions:
The evaluation indexes of body weight are as follows: below 60% of standard body weight, 60-80% of severe malnutrition, 80-90% of moderate malnutrition, 90-10% of mild malnutrition, normal range >120% of obesity.
Extended data different age algorithm
Standard weight (kg) = age x 2+8 (7-16 years old)
Mild obesity: 20%-30% over standard weight.
Moderate obesity: 30%-50% over standard weight.
Severe obesity: more than 50% of the standard weight.
Weight control
Weight control programs can use four kinds of therapies: diet and nutrition counseling, behavioral therapy, drugs and surgery. Nowadays, traditional diet therapy is rarely used; Instead, emphasize changing long-term habits. Most programs teach customers how to eat safely, wisely and gradually. Changes include increasing the intake of complex carbohydrates (fruits, vegetables, bread, cereal products, pasta products) and reducing the intake of fat and simple carbohydrates. A diet that provides 400~800kcal of extremely low energy every day has become less popular, because it is obvious that patients can regain their weight quickly.
Standard weight
The "standard" of standard weight is not exactly the same in different countries. The standard weight of different age groups in a country is usually obtained through a large sample survey in the country. According to people's age and height, the general range of weight of people in each age group is calculated, and its upper and lower limits are stipulated. The Sports Research Institute of China's State Sports Commission has made a standardized study on the weight of children under 15 years old. If you look at this standard, you will understand whether your child's weight is standard.
Abnormal weight
Because people's weight is related to many factors, there are differences between different human bodies, and there will be certain changes at different times of the day. In addition, the geographical location (such as gravity), seasons, climate and their own situation also have certain effects on weight, so it is difficult to fully meet the standard weight. That is to say, it is difficult to express it with a constant value, but it should be a numerical range. We call this numerical range a normal value, which is generally within the range of standard weight+10%. Beyond this range, it can be called abnormal weight.
UNDERWEIGHT (underweight)
Long-term underweight will lead to hair loss, anorexia, infertility, ulcers, dizziness, irregular menstruation, and osteoporosis in old age. It will also have an impact on thinking and reasoning ability. Doctors will advise us to run more and learn to control our food intake. In today's society, "obesity" is a common phenomenon. But for people at the other extreme, being too thin is also a risk.
Susan Ringwood Eating Disorders Association pointed out:
We pay attention to the impact of this disease on family and friends, which is long-term, because the impact of this disease is most likely to begin when a person is 14 years old, and it will last for about 6 years, which means that their education is interrupted during their adolescence, and their academic deficiency will even affect their employment prospects.
Now people will use BMI index to calculate whether their weight is standard or not. BMI, the body mass index, is the number obtained by dividing the weight in kilograms by the square of the height in meters. When the body mass index is less than 18.5, you are underweight, and when the BMI is18.5 ~ 24.9, it is normal.
We should believe that being underweight is neither healthy nor beautiful. Unfortunately, the best weight recognized by doctors is completely different from that recognized by fashionistas. In the fashion industry, "thinness is beauty and thinness is the future" is almost an unwritten rule. It is reported that Isabel Carroll, a "skinny" model who took nude photos to fight anorexia in France, was only 28 when she died.
Carol, whose height 1 m 65, weighs less than 30 kilograms for a long time. Her death has sounded a wake-up call to people who are obsessed with losing weight, making people realize that being too thin is not only dangerous, but also leads to death. Fortunately, plump and sexy beauties like kate winslet and Sophie Dahl are challenging the current aesthetics.
Blindly rejecting diet may lead to anorexia, resulting in a rapid decline in physical function, but there are still a large number of women who are constantly losing weight, even those who are already slim. Everything will turn into extremes. We should think about "why this deadly trend will become a fashion".
