Hey, that's an improvement!

The ranks of obese Americans are expected to swell even further in the coming years, rising from 36% of the adult population today to 42% by 2030, experts said Monday.
Kicking off a government-led conference on the public health ramifications of all those expanding waistlines, the authors of a new report estimated that the cost of treating those additional obese people for diabetes, heart disease and other medical conditions would add up to nearly $550 billion over the next two decades.
The sobering projections also contained some good news, the researchers said: Obesity's growth has slowed from the record pace of most of the last 30 years. If those trends were to continue, 51% of American adults would qualify as obese in 2030.
Study leader Eric Finkelstein, a health economist at Duke University in Durham, N.C., said it was unclear whether growth had slowed thanks to public policy initiatives aimed at preventing childhood obesity, greater societal awareness of obesity's health risks, or because Americans have hit the maximum level of fatness a population can sustain.
The findings are based on data collected from 1990 through 2008 as part of the Behavioral Risk Factor Surveillance System, a survey by the CDC and health departments in the states. Measures of obesity were based on body mass index, which is calculated as weight in kilograms divided by height in meters squared. A BMI of 18 to 24.99 is considered healthy; those in the 25-29.99 range are considered overweight; people above 30 are classified as obese, and those above 40 are severely obese.
In January, two CDC studies suggested that obesity rates were stabilizing at 17% for children and 35% for adults. That was based on data from the National Health and Nutrition Examination Survey.

They place a particular emphasis on children, based on a statistic that emerged from the landmark Bogalusa Heart Study: 77% of obese children become obese adults, while only 7% of non-obese children do.
For weight gain to be averted let alone reversed policymakers would have to move beyond politically palatable initiatives such as removing sugary sodas from schools and planting community gardens in urban food deserts, said Robert Jeffery, an epidemiologist and weight-loss researcher at the University of Minnesota. Very likely, junk food would have to be taxed to discourage consumption, and advertising for those products would have to be prohibited, he said.
