It's not hard to work out, even in primary care. It's a simple calculation that could be done in a web page on your pc. Enter height, weight, waist, hip, wrist (or neck or whatever is used in the chosen formula) and you get a number accurate to within a few percent.
And anyway, what's wrong with taking a pop at NICE
