Blast from the Past
Last week, Forbes.com described how the journal Nature admonished Walter Willett, a leading nutrition and epidemiology researcher at the Harvard school, for being biased against scientists who reach different conclusions than he does. Specifically, they focused on his criticism of the recent study by Katherine Flegal and colleagues demonstrating that being slightly overweight may actually be protective. While this study suggests that decades of advice to avoid even modest weight gain may be misguided, and that a little bit of extra weight is particularly beneficial for older adults, Willett called the study “rubbish” and not worth reading. Many obesity experts and health biostatisticians take issue with the harsh tone of Willett’s statements, and as one of the most frequently quoted academic sources on nutrition in the news media, Willett’s opinion holds significant weight with the public. Unfortunately, Willett tends to argue against any scientific research that contradicts the public health recommendations he, and the nutrition department at Harvard, have made.
In February, I wrote an article describing the various explanations that could account for the protective effect of overweight seen in various studies, including the meta-analysis that Willett took such issue with. While obesity is not a desirable state of health, it’s worth noting that if you’re living a health-promoting lifestyle but still carrying around a few extra pounds, you might be healthier than popular media would lead you to believe.
What’s ironic about Willett’s criticism of Flegal’s study is that a research team he led recently published a study that generated huge controversy when its conclusions were retracted at the last minute by the publicity team at Harvard’s teaching hospital. The data were so weak and unsupportive of Willet’s claims that the paper was rejected by six journals before it was finally accepted by the American Journal of Clinical Nutrition, where Willett is a member of the editorial board (as pointed out in the Forbes.com article). Regardless of whether Willett is right or wrong in his criticism of Flegal’s study, publicly blasting another researcher for drawing unfounded conclusions from their data seems a little out of line given his own recent experience.
