This is a really great Ted Talk by Peter Attia. He’s had an interesting and evolving career that included leaving his surgical residency to join McKinsey & Company as a consultant, and describes McKinsey as “certainly the most stimulating experience of my professional life.”
His own personal experience led him to become more and more interested in obesity, and he’s trying to think about it differently. He believes (and I strongly agree) that the conventional wisdom of nutrition is failing us. He sees obesity as a symptom of a much bigger problem, and explains how insulin resistance is the culprit, triggered by the sugar and refined starches that we consume. Yes!
