Introduction to obesity:
It refers to a certain degree of obvious overweight and thick fat layer, which is a state caused by excessive accumulation of fat, especially triglycerides in the body. Excessive food intake or changes in the body's metabolism lead to excessive fat accumulation in the body, which leads to excessive weight gain, and causes pathological and physiological changes or latency in the human body.
Evaluation criteria: Obesity = (actual weight-standard weight) ÷ standard weight × 100%. The methods of losing weight include enema, osmotic pressure, sauna, milk powder, skipping rope and Pu 'er tea.
Determination of obesity:
At present, the commonly used body mass index (BMI) has also been translated into BMI. This is an index for calculating height and weight. The specific calculation method is to divide the weight (kg, kg) by the square of the height (m, m), that is, the body mass index = weight/height/height (kg/m2).
Research shows that the body mass index of most individuals has obvious correlation with the percentage of body fat, which can better reflect the degree of obesity.
According to the analysis of the degree of obesity by body mass index, the critical value of body mass index of the World Health Organization (WHO) is usually adopted internationally, that is, the body mass index of 25.0~29.9 is overweight and over 30 is obese.
The China Office of the International Society for Life Sciences organized the "China Obesity Working Group" composed of multidisciplinary experts, and collected and analyzed the relevant data of 240,000 people in 2/kloc-0 provinces, cities and regions in China, including body mass index (BMI), waist circumference, blood pressure, blood sugar and blood lipid.
Based on this, the body mass index puts forward the standard of China people. Body mass index "24" is the limit of overweight in China, and body mass index "28" is the limit of obesity in China. The limit of abdominal fat accumulation is male waist circumference ≥85 cm and female waist circumference ≥80 cm.
