This week’s circle is at skeptical surfer’s blog. Although I think Christian has made an error or two in his evaluation of the latest NHANES studies and what they say about obesity. For one, obesity has always been 30+ BMI, overweight was changed from 27 to 25 by one government agency responsible for surveillance of disease (CDC) to conform with other agencies’ metrics. Further as I explained, the NHANES studies are hardly single variable, and don’t take into account a change in medical culture towards better secondary prevention of comorbidity in the overweight and obese. It’s all good though. I appreciate an honest effort.
