Liz Sturgiss and I decide to tackle diabetes – do we even know what we are diagnosing, or is it a ‘category error’? Does metformin have anti-aging properties? If so, why isn’t Justin taking it?

Justin’s Factoid focuses on wacky newspaper headlines about medical research, then Liz makes him squirm with her nasty ethical dilemma.

    Hi Justin I’m a retired GP who lectures to the public on T2DM, metabolic syndrome, with a focus on low carbohydrate diets. Your podcast on diabetes was most interesting. I subscribe to the view that the underlying early warning sign is hyperinsulinaemia secondary to glucose intolerance. Hyperinsulinaemia often precedes fasting hyperglycaemia and raised HbA1c by decades Regards John Beaney


  2. That was a brilliant “What would Justin do?” segment. Nice work, Liz!
