those of us who want to achieve and maintain a healthy weight can’t afford to think about obesity as an energy balance problem. It gets us nowhere we haven’t already been our entire lives. We have to think about it as a hormonal, metabolic, and physiological problem, perhaps akin to diabetes, as Astwood suggested. Some of us who don’t seem to have it now are going to get it as we age. Some of us aren’t. Some of us can load up on ice cream, pie, meat, and potatoes and stay lean as a west Kansas coyote; some of us can’t.
