ABSTRACT
Although body weight is a complex scientific matter, at a public policy level there is probably only one point that matters: how many overweight and obese people are there? After all, continuing improvements in the general health of Western populations does not seem to have been enough to convince Western policymakers that the obesity dragon has been slain or that it is less fierce than first thought. Faced with calls for drastic action from a wide range of lobby groups, Western governments have simply been unable to say ‘What crisis?’
