These projects are more vulnerable to documentation drift because small inconsistencies in preparation inputs can propagate across measurement layers and create avoidable uncertainty

Occupancy stays low, but each engaged receptor keeps sending its main message longer than it would under a balanced signal (cAMP bias with low receptor internalization). In a head-to-head trial against liraglutide, tirzepatide reduced measured food intake and craving more despite lower GLP-1 occupancy. The effect lowers the drive to eat rather than increasing restraint
