For different races, the same body mass index may represent different degrees of obesity. The level of body mass index in Asia (including China) is lower than that in European countries as a whole, but according to many studies, Asians are already at high risk of cardiovascular diseases at a low level of body mass index.
Body mass index greater than or equal to 24 is overweight, and greater than or equal to 28 is obese; Male waist circumference is greater than or equal to 85 cm, and female waist circumference is greater than or equal to 80 cm. If there is no specific standard to judge people's nutritional status, we can only use some relatively vague words such as "normal", "good", "obesity" and "emaciation" to describe it.
