Research on excess body weight and obesity has long been predicated on the fundamental assumption that weight is gained based on a “calories in, calories out” equation. If you consume more calories than you expend, you gain weight, right? Science reporter Gary Taubes and reader-turned-friend Nick Gulino are among a growing faction that says it might not be so simple.
Instead, they believe there may be a hormonal or regulatory dysfunction in the body that leads certain people to gain weight more easily than others. The theory does not indicate that weight gain is the result of personal habits or choices like the current paradigm does. As Gulino himself has experienced, this too often leads to a culture of fat-shaming and blame for heavy individuals.
