Sandy Szwarc is an expert on food science and scientific study design, amongst many other accomplishments. She writes the blog junkfoodscience.com which seeks to dispel many of the lies spread through bad science and even worse journalism about obesity.

Some choice quotes:

...And the promotion of weight-height measures for individual children as a way to identify those in need of interventions is similarly without support. According to scientists at the CDC’s National Center for Health Statistics, BMI is a screening tool [for public surveillance], not a diagnostic tool, and BMIs over cut-offs don’t equate to clinical complications or health risks. After a comprehensive review of 40 years of evidence — about 6,900 studies and abstracts — on screening and interventions for childhood and adolescent “overweight,” the U.S. Preventive Services Task Force recently found no quality evidence to support that childhood “overweight” is related to health outcomes.

...In other words, today’s report could more accurately been titled: “Obesity Among Adults in the United States — No Change Since 1999-2000.” There has been no statistically significant change in obesity rates for the past 7 years. That’s “obesity.” Not just those a few pounds “overweight.

Cory, as much as I respect you, you fall into the category of journalists who spread disinformation about obesity on a semi-regular basis.
