Diet labels might reshape taste by tricking the brain, study finds

A neuropsychology study found that when people expect sugar, artificially sweetened drinks feel more pleasant and trigger stronger reward-area brain activity, suggesting labeling like “diet” or “low-calorie” can shape taste experience beyond the actual flavor. The research used a small, healthy sample and varied cues about sugar versus sweetener, highlighting the potential impact of expectations on eating and indicating a need for larger studies to confirm broader implications.
