GLP-1 medications (glucagon-like peptide-1 receptor agonists) are prescription drugs originally developed to treat type 2 diabetes that work by influencing appetite regulation, blood sugar control, and gastrointestinal function. Individuals with higher body weight can reduce food cue–driven eating and “food noise,” reshape eating patterns, and influence how they experience hunger, fullness, and the reward from food, with important implications for mood, body image, and eating behavior. GLP-1 medications relate to nutritional psychology because they directly alter appetite, food cues, and eating patterns, changing how people experience eating and thereby influencing mood, body image, and mental health within the broader diet–mental health relationship.
