Unexpected Brain Mechanism Challenges Assumptions About GLP-1s

Ozempic may have revealed the brain’s hidden “craving center”

Ozempic-like drugs appear to weaken more than hunger—they may also reduce cravings for alcohol and other addictive substances. Scientists are increasingly tracing this effect to the lateral septum, a brain region that helps connect memories and surroundings with rewarding experiences. Packed with GLP-1 receptors, it may act as a crucial control point between thinking about a reward and feeling compelled to pursue it. The discovery could open new…

Unexpected brain mechanism challenges assumptions about GLP-1s

For decades, obesity medications produced only modest weight loss. But in recent years, Ozempic and related GLP-1 therapies have transformed the field, enabling sustained weight loss of 10% to 15% or more. Despite their success, however, scientists have not fully understood how these drugs work in the brain.

New study may change how we think about GLP-1s

In a new study, Yale researchers identified an unexpected mechanism that challenges a long-held assumption about the brain’s hunger circuitry.
