May 11 is World Obesity Day. According to data released by the National Health Commission a few days ago, the obesity rate of mainland residents is on the rise, with the obesity rate of residents aged 18 and above reaching 16.4%. Obesity has attracted more and more attention as a risk factor for many chronic diseases. So, how can you tell if you are obese?
The obesity rate of mainland residents is on the rise
There is a clear measure of obesity in medicine, which is body mass index. It is a metric calculated based on height and weight. Body mass index is a figure equal to the square of body weight (kg) divided by height (m). A normal body mass index ranges from 18 to 24. For example, a woman who weighs 60 kg and is 1.60 meters tall has a BMI of 23.44.
Zhang Peng, Chief Physician of Bariatric and Metabolic Surgery, General Surgery Center, Beijing Friendship Hospital: If the weight is overweight, and the BMI (body mass index) is between 24 and 28, these people often have an extra weight of 10~20 pounds, then these people should actively undergo intensive lifestyle intervention, we should subtract almost 1/4 of the food from the daily intake, and the amount of exercise should increase by 1.5~2 times than usual. If the BMI (body mass index) is more than 28, it is obesity, we need to use some drugs, if the BMI (body mass index) is higher than 32.5, the excess weight is at least 40 pounds, then we may also have to use bariatric surgery to achieve the purpose of weight loss.
Experts believe that the basis of weight loss is to do a good job of healthy lifestyle management, achieve a balance between eating and moving, and let the calories absorbed be less than the calories consumed. Exercise is an effective means of consuming human body calories, and obese people should choose appropriate exercise items according to their own conditions. Adult obese patients should have a comprehensive, balanced and varied diet, limit total energy intake, and avoid eating after 9 p.m. as much as possible. In the process of weight loss, it is recommended that the dietary energy of obese children and adolescents be reduced by about 20% on the basis of normal requirements. The faster the weight loss rate is not the better, the reasonable weight loss rate is 2~4 kg per month.
Is it reliable to lose weight without carbs?
In recent years, weight loss by reducing or blocking carbohydrate intake has gained popularity on some social media. Is this method called "low-carbon weight loss" reliable?
Carbohydrates are broken down by the body to produce glucose, an essential nutrient for the body, and once consumed in excess, the glucose that cannot be consumed will be converted into fat and stored in the body. "Low-carbon weight loss" is to reduce carbohydrate intake, the human body from carbohydrates to fat as the main source of energy, in order to achieve the effect of weight loss. Experts believe that taking the method of not eating staple foods or eating vegetarian food to lose weight, although it can make people fall off the scale in a short time, it is difficult to last, and it will bring some side effects.
Experts believe that the basic principle of obesity prevention and treatment is balanced nutrition, and protein, fat, and carbohydrates should be reasonably matched as much as possible to meet the basic physiological needs of people, so as to achieve the long-term effect of obesity prevention and treatment.
Chen Wei, Chief Physician of the Department of Clinical Nutrition, Peking Union Medical College Hospital: Because many of our important organs, such as the brain, such as the heart, what is the most important source of energy that it uses? It's carbohydrates, which are what we call sugars, but why are people so afraid of sugar? In fact, that sugar is what we refer to as added sugar or extra sugar, and it is true that too much added sugar will have a negative impact on obesity, so what we mean by eating less sugar is not to eat less staple foods, but to eat less of these delicate carbohydrates and added sugars.
Carbohydrates are indispensable functional substances for the human body. The Chinese Nutrition Society recommends that 50% to 65% of the total dietary energy of Chinese aged 18 to 49 come from carbohydrates, and the average adult should consume 250 grams to 400 grams of grains per day.
