In a rare deep-brain recording study of a woman with severe obesity and loss-of-control eating, tirzepatide — sold as Mounjaro and Zepbound — temporarily silenced activity in a key reward region linked to “food noise,” or intrusive thoughts about food. About five months later, those brain signals and intense food preoccupation reappeared, suggesting the drug’s effects on this patient’s cravings were short‑lived.
