Fatty Liver Expert: Your Liver Is Filling With Fat Right Now - Dr David Unwin
"I fundamentally believed that drugs is what I should be using, medication, and that lifestyle was a sort of add-on. Isn't that terrible? I didn't think that the biscuits made that much difference."
Dr. Unwin revealed that despite being a senior GP for 25 years, he didn't believe lifestyle interventions were central to patient health, viewing medication as primary treatment. This admission exposes a widespread medical culture that prioritizes pharmaceutical intervention over dietary and lifestyle changes, even as patient health deteriorated under his care.

About this episode

In this episode of The Diary of a CEO, host Steven Bartlett interviews Dr. David Unwin, named among the UK's top 10 most influential doctors in 2018, for a candid discussion about the metabolic health crisis devastating young people and the systemic failures in medical dietary advice. Dr. Unwin makes several shocking revelations, including that NHS doctors are financially incentivized to prescribe diabetes medication and that he spent 25 years blaming patients for weight loss failures while giving them advice that never worked. The conversation centers on the explosion of type 2 diabetes in young people, a disease that didn't exist in anyone under 55 when Unwin began practicing in 1986 but now affects children as young as their early twenties. Dr. Unwin explains how a confrontational patient in 2012 exposed his ignorance about the sugar content in common foods like bread and rice, leading him to develop a revolutionary low-carbohydrate approach that has achieved 93% remission rates in prediabetics and gotten 157 patients off diabetes medication entirely. The episode features dramatic demonstrations including sugar cube equivalents for common foods, revealing that a bowl of cornflakes contains 8 teaspoons of sugar and white rice contains 10. Dr. Unwin introduces his wife Jen's GRIN behavioral change model and discusses the reality of ultra-processed food addiction, describing a patient who ate bread his wife had sprayed with bleach. The conversation concludes with alarming statistics about declining healthspan in the UK and the hidden £7,000 annual cost every British taxpayer bears for diet-related illness consequences.
