    Episode 14. The Neuroscience of GLP-1 agonists

    Summary AI-generated summaries are soooo 2024. We're talking all things GLP-1 agonists and the brain (spoiler - it's so much more than a fat loss drug). Learn about the drug mechanisms in the brain, its potential benefits beyond weight loss, the implications for mental health and addiction, and the societal context surrounding their use. Unsurprisingly, we conclude by emphasising the need for a nuanced understanding of these drugs and the importance of lifestyle changes alongside medical interventions.
