GLP-1 Drugs & Bariatric Surgery Explained by a Top Obesity Researcher | Dr. David Allison
Episode 199
Tuesday, 31 March, 2026

In a world flooded with conflicting health advice, how do you actually figure out what’s true? Dr. David Allison, one of the most rigorous scientific minds in obesity and nutrition research, shared the exact framework he uses to evaluate evidence, from peer-reviewed trials to podcast recommendations to AI-generated summaries. He explains the difference between trusting science as a process and trusting individual studies, why most nutrition epidemiology functions more like advertising than research, and how ordinary people can build a reliable filter for health claims without a PhD.Want ad-free episodes?
