May 11th is World Obesity Day designated by the World Health Organization. According to the “Report on the Status of Nutrition and Chronic Diseases of Chinese Residents” released in 2020, nearly half of adults and 1/5 of children in my country are overweight or obese, which has become the country with the largest number of overweight or obese people in the world. Experts remind that there are many misunderstandings in the current popular weight loss methods in the society, and you need to choose carefully.
Obesity is a chronic metabolic disease. The international standard for determining obesity is body mass index (BMI), which is equal to weight (kg) divided by height (m) squared. According to the World Health Organization, overweight is defined as a BMI greater than or equal to 25, and obesity is defined as a BMI greater than or equal to 30.
“Dietary Guidelines for Chinese Residents (2022)” shows that the combined proportion of adult residents in my country has reached 50.7%, and the overweight and obesity rates of children under 6 years old and children and adolescents aged 6-17 years have reached 10.4% respectively. % and 19.0%, and the overweight and obesity rates of residents aged 18 and over were 34.3% and 16.4%, respectively. Obesity brings not only the trouble of getting out of shape, but also causes diseases such as high blood pressure, heart disease, hyperuricemia, diabetes and arteriosclerosis. As early as 1997, the World Health Organization has clearly defined obesity as a disease. Various diseases caused by obesity are increasing year by year, and the trend is younger.
Chen Wenhe, a professor at Shanghai Institute of Physical Education, said that the most effective way to prevent and treat obesity is to develop a healthy lifestyle, that is, “reasonable diet + physical activity”. It should be noted that many “slimming tips” are not scientific. The so-called “diet to lose weight” and “starvation therapy” often hurt the body. Lose weight and avoid some misunderstandings, no meat ≠ no gain, weight loss ≠ fat loss, obesity ≠ overnutrition.
Yu Anqi, chairman of Peak Weight Loss, said that weight loss does require some control of diet, but it does not mean that the less the better, but the adjustment and optimization of the diet structure. Formulating a scientific, reasonable, feasible, and individualized weight loss exercise prescription is the basis for ensuring exercise safety and weight loss effect.
