#292 Can Keto Work and Is It Actually Unhealthy? with Dr Nick Norwitz
9th Apr 2025
What if everything you thought you knew about cholesterol, fat and metabolic health was up for debate?
As someone interested in nutrition research, I’m always up for exploring differing points of view especially when they come from a rigorous scientific background and can speak to the evidence base.
So in this episode, I sit down with Dr Nick Norwitz PhD, to challenge some of my long held positions in nutrition science and break down keto.
He’s a researcher and expert in ketogenic diets, lipid metabolism, and metabolic health as well as a current medical student at Harvard Medical School.
👉 His 1-year study is now published here.
👉 And the full breakdown is here.
We discuss:
🔥 Nick’s personal journey with IBD and the ketogenic diet
🥑 Whether saturated fat actually causes heart disease?
📉 Cholesterol confusion – and whether we should all aim for a lower LDL-C or ApoB by any means necessary?
💡 Keto as a metabolic state vs. a diet – what it means for fat loss
📊 The problems with nutrition research
Plus, we explore how to measure metabolic health, keto adaptation, and whether a high-fat, high-animal-protein diet can be optimal for longevity.
