肥胖(obesity)的定义:
Obesity has been more precisely defined by the National Institutes of Health (the NIH) as a BMI of 30 and above. (A BMI of 30 is about 30 pounds overweight.) The BMI (body mass index), a key index for relating body weight to height, is a person's weight in kilograms (kg) divided by their height in meters (m)squared. Since the BMI describes the body weight relative to height, it correlates strongly (in adults) with the total body fat content.

Ha ha, when i started resident decade ago, 250 lb would raise the red flag, now a days pt 350+ lbis not a big deal. Seeing 400+lb all the time. People don't realize obesity is a disease and worse thing is it can kill you.
我家LD也这么说,我们相互鼓励对方多吃,还有理论叫“相对减肥”,呵呵
哈哈,有的人天生骨骼粗壮,肌肉又紧实,看起来很fit,一称量发现很重。本楼主认为这一类的人用BMI指数不合理。
楼主上传的照片看起来满健壮的,应该是骨骼和肌肉占去了大部分的比例,这样一来,BMI就该失效,不应被划为OVERWEIGHT。
如果腰围过大,倒是要小心才是。
谢谢几位啊!我大概是过了25不多,还好只是Overwright:)
overweight BMI 25-29, obesity 30-39, morbid obesity > 40
