Dr. Vera Tarman talks with Dr. Thomas Sambrook, a psychology lecturer at the University of East Anglia, about why the brain keeps responding to food cues after we are full. His research found that people still showed a strong reward signal to cues for a food they had just eaten their fill of, even while saying they no longer wanted it. They discuss habit versus addiction, the pull of advertising and cues, and practical steps like cue hygiene and replacing a habit instead of only resisting it. The takeaway is a shame-free, biology-based explanation for eating when not hungry.
