The Obesity Epidemic

There’s a new HBO documentary coming out looking at the obesity epidemic in America. And Gary Taubes picks holes in it

But when David Wallinga of the Institute for Agriculture and Trade Policy tells us in The Weight of the Nation that the USDA has established the cause of the obesity epidemic and it’s “an increase in our calorie consumption over the last 30, 35 years,” he also tells us where those calories come from: a quarter come from added sugars, a quarter from added fats (“most of which are from soy”), and “almost half is from refined grains, mainly corn starches, wheat, and the like.” What Wallinga doesn’t say is that the same USDA data clearly shows that red-meat consumption peaked in this country in the mid-1970s, before the obesity epidemic started. It’s been dropping ever since, consistent with a nation that has been doing exactly what health authorities have been telling it to do.

If The Weight of the Nation accomplishes anything, it’s communicating the desperation of obese Americans trying to understand their condition and, even more, of lean (or relatively lean) parents trying to cope with the obesity of their offspring. Lack of will isn’t their problem. It’s the absence of advice that might actually work. If our authorities on this subject could accept that maybe their fundamental understanding of the problem needs to be rethought, we and they might begin to make progress. Clearly the conventional wisdom has failed so far. We can hold onto it only so long.
