GLP-1 Drugs Dramatically Reduce “Food Noise” in Weight Loss

GLP-1 medications effectively "turn down the volume" on intrusive food thoughts. In a study of 417 adults, those combining medication with behavioral therapy saw a significantly greater reduction in "food noise" than those using therapy alone, offering a potential neurobiological explanation for the success of these new obesity treatments.
