Q. How can we break this cycle?
A. Changing how people look at food is essential. Look at the public-health success with tobacco. We didn’t change the product. But we changed how people perceive it. Now people look at tobacco and say, “That’s really disgusting.” Tobacco is easy because you can live without it, but you can’t live without food. So you have to cool down the stimulus. You have to retrain yourself to respond to food differently.
