Long viewed as largely a personal problem for patients and their physicians
to address, obesity is now garnering the attention of policymakers. From the
World Health Organization (WHO) down, public health advocates are engineering
ambitious plans to reduce obesity by changing society.
The effort is being driven by the growing proportions of the problem.
Nearly one third of US adults are obese, defined as having a body mass index
(BMI) of 30 or higher. Another third are overweight, with BMIs between 25
and 30. That leaves just one third of the population at what most physicians
consider a healthy weight.
