    Megan: So we can’t save billions of dollars by making people thinner?

    Paul: Consider the methodology of this study. It tried to calculate changes in health costs if everybody with a BMI over 30 had a BMI under 25. But leaving aside the preposterous assumption that all increased health risks associated with a level of body mass are caused by that level of body mass, the idea that somehow we could make fat people into thin people is bizarre.

    A study like this isn’t talking about turning 180 pound women into 165 pound women, which at least in theory might actually be possible. It’s talking about turning 200 pound women into 130 pound women, on statistical average. The success rate for such attempts is about .1% Even stomach amputation does not turn fat people into thin people.
