A doctor says wellness culture is a con. He's half right. We fact-check The Fat Doctor Podcast on carbs, exercise, sugary drinks and type 2 diabetes.

Health Griftluencer October, week four. After a chef, a doctor and a woman who wasn't sick, Burndog and Julie take on Dr Asher Larmie (he/they) and The Fat Doctor Podcast episode "Wellness Culture and Diabetes Care". There's a lot to agree with: moralising about health is real, stress and sleep really do move blood sugar, and most people with type 2 diabetes don't need to test all day. But "carbohydrates are essential for life", "exercise raises blood sugar" and "there's no decent evidence diet and exercise help" don't hold up against the trials.

In this episode:

• Can you actually live without carbs? What the Institute of Medicine says
• Does exercise raise or lower blood sugar? The ADA guidance, and why hypo warnings matter
• Sugary drinks and type 2 diabetes: what 17 studies found
• "Good diabetic, bad diabetic", and why that moral language does harm
• GLP-1 side effects, and why you shouldn't just push through (or just stop)
• Wellness culture and disordered eating
• A book plug in an episode about people selling you things

We're a podcast, not your doctor. If you have diabetes or take diabetes medication, talk to your GP or diabetes nurse before you change anything.

Belle Gibson, Pete Evans and Karl Stefanovic walk into a juice bar. "I don't have cancer", says Belle. "Neither do I", says Paleo Pete. "What did you call me?" says Karlost. On this week's health Griftober episode, we talk about Belle Gibson. A terrible topic for people who want to hear about a proper grift.

Karl appears to have returned and he brought a friend with him. Dr Nick Norwitz is definitely not Pete Evans, but were there still chinks in his shiny peptide fuelled armour?
