In Reply: The goal of our study was neither to endorse nor to criticize the standard BMI categories developed by the World Health Organization, but rather to summarize the published findings on mortality from studies that used those widely recognized categories.
As Dr Viña and colleagues point out, these are categories of weight and not body composition. Our purpose was to present summary estimates that, as we stated, “may help to inform decision making in the clinical setting,” a view we believe is reinforced by the Editorial by Heymsfield and Cefalu.1
