There are 2 health topics active atm, so I thought a BMI topic would fit as well. What's your BMI? Find out here. I'm 180cm (well, almost) and 58kg. My BMI is 17.9.
24.9, just 1lb UNDER the recommended upper limit for 'normal'
HOWEVER.... these silly charts are a complete waste of space! Why? well, as anyone will tell you, muscle is denser than fat, therefore 1lb of muscle takes up a lot less space than 1lb of fat.
In other words, somebody who weighs 11 stone (154lbs) and works out, has a sixpack, nice pecs etc; will look a lot healthier than a 'lardass' who has the same weight and height, but is mostly fat!
last time i checked it was 20.3, but that was a while ago. my weight is very stable though (based on experience, didn't check it for... a lot of time )
