A short educational YouTube talk by Robert Whitfield MD (uploaded May 17, 2025) explaining how GLP-1 (glucagon-like peptide-1) influences brain and gut processes. The speaker claims that high/bolus GLP-1 can act centrally (bypassing the vagus nerve and behaving as a neurotransmitter), leading to reduced appetite via delayed gastric emptying and reported reductions in alcohol use, addiction behaviors, and depressive symptoms.
