Ozempic May Have Revealed the Brain's Hidden "Craving Centre" Ozempic and similar GLP-1 drugs are well known for reducing appetite and driving weight loss. But a growing body of research suggests these drugs also reduce cravings for alcohol and other addictive substances, and scientists believe they may have finally identified the specific brain region responsible. The unexpected side effect that started this line of research: Beyond their well publicised weight loss effects, GLP-1 agonists have shown a genuinely striking secondary effect. Human studies show these drugs reduce alcohol consumption, and preclinical animal studies suggest they also reduce use of cocaine, amphetamines, opiates, and nicotine. Why the brain's known reward centres don't explain this: The brain's classic reward circuitry involves the ventral tegmental area and nucleus accumbens, regions that produce dopamine and have been studied for decades. These would seem like the obvious place to look for how GLP-1 drugs affect craving. However, these regions lack a significant density of GLP-1 receptors, making them unlikely to be where these drugs are actually acting directly. The brain region now under the spotlight, the lateral septum: One step upstream from these dopamin
