The BMI measurement is flawed

I honestly don't think a lot of people in western world realise how fat they are. Compare your average Britain, to your average (non starving) Indian.

All the goal posts have been moved in the devoloped world, what was once considered overweight is now considered normal.

 I agree. We have moved the goal posts with respect to our perception of what is "normal".

BMI is approximate and is only ever going to be a rough guide ... but it gives a huge range for being in the "healthy" region which is supposed to cover "body types" (e.g. 6ft male the range is 10s 3lb to 13s 9lb).

My bmi is just touching the upper limit for my height yet I'm physically pretty fit, have very little fat and I'm not massively muscular either, although I do weight train 2-3 times a week.

I tend to agree that it's a dumbed down way of showing people which band they fall into, but most people who are aware of their fitness levels and watch what they eat tend to ignore it anyway so it's not massively relevant.
