Overweight: body mass index = 25-30.
Mild obesity: body mass index >; 30
Moderate obesity: body mass index >; 35
Severe obesity: body mass index >; 40
Guiding opinions:
Weight evaluation indicators are as follows: 60% below standard weight, 60-80% severely malnourished, 80-90% moderately malnourished, 90- 1 10% mildly malnourished, normal range > standard weight 120%, obesity.
Extended data unequal age algorithm
Standard weight (kg) = age x 2+8 (7- 16 years old)
Mild obesity: 20%-30% overweight.
Moderate obesity: 30%-50% overweight.
Severe obesity: more than 50% of standard weight.
weight control
Weight control programs can use four therapies: diet and nutrition counseling, behavioral therapy, drugs and surgery. Nowadays, traditional dietotherapy is rarely used; Instead, it emphasizes changing long-term habits. Most programs teach customers how to eat safely, wisely and step by step. Changes include increasing the intake of complex carbohydrates (fruits, vegetables, bread, cereal products and pasta products) and reducing the intake of fat and simple carbohydrates. A very low-energy diet of 400~800kcal per day is not so popular, because it is obvious that patients can regain their weight quickly.
standard test 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 national sample survey. According to people's age and height, the approximate range of people's weight at all ages is calculated, and its upper and lower limits are stipulated. The Institute of Physical Education of the State Sports Commission of China made a standardized study on the weight of children under 15. If you look at this standard, you will understand whether the child's weight is standard.
Abnormal weight
Because people's weight is related to many factors, there are differences between different people, and there will be certain changes at different times of the day. In addition, geographical location (such as gravity), season, climate and one's own situation also have certain effects on weight, so it is difficult to reach the standard weight completely. In other words, it is difficult to express it with a constant value, but it should be a range of values. We call this numerical range a normal value, which is generally within 10% of the standard weight. Beyond this range, it can be called abnormal weight.
Underweight (underweight)
Long-term underweight can lead to alopecia, anorexia, infertility, ulcers, dizziness, irregular menstruation and osteoporosis in the elderly. It will also have an impact on thinking and reasoning ability. The doctor will advise us to run more and learn to control our food intake. In today's society, obesity is a common phenomenon. But for the other extreme, being too thin is also a risk.
Susan Lynwood 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 start when a person is 14 years old, and will last for about six years, which means that their education will be interrupted at puberty, and their academic deficiency will even affect their employment prospects.
Now people will use the body mass index to calculate whether their weight is standard or not. Body mass index, or 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, it means that you are underweight, and the body mass index is normal when it is 18.5 ~ 24.9.
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 world, "thinness is beauty, thinness is the future" is almost an unwritten rule. It is reported that Isabel Carroll, a "skinny" model who took nude photos in France to fight anorexia, died at the age of 28.
Carlo is 1.65 meters tall and weighs less than 30 kilograms for a long time. Her death sounded the alarm for people who are obsessed with losing weight and made 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.
Blind refusal to eat may lead to anorexia and 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 go to extremes. We should think about "why this deadly trend has become a fashion".
