Even if a genetic test could reliably predict obesity risk, would people make effective use of the information? In fact, researchers have worried that when people learn that they are at high genetic risk for diseases like obesity, people would become fatalistic and stop trying to change their behaviors. It’s also possible that a careful probe of the genes – rather than the abstract risk score – could identify genetic variants that actually reduce a person’s risk of obesity.
