  • So helpful

    I’m loving this podcast. Dr Karan and his guests are so knowledgeable. I never thought I would enjoy listening to a podcast about feet. I have chronic PF and found the June 14th podcast very helpful.

  • It’s lost its way

    I’ve now lost confidence in the academic rigour of Dr Karen. In the latest episode on supplements he tells his contributor that by switching around the supplements he takes, he’s in effect carrying out a random controlled experiment on himself! This is such a misunderstanding of the RCT process it makes the information in whole podcast questionable. I’ll look elsewhere for my information.

  • Fantastic podcast

    Clear, digestible advice. No demonising of foods which I think runs prevalent in the ‘health’ podcast world ! Doesn’t have any charlatans on.

Talking Points

Recent interactions between the hosts and their guests.

The Dangerous Invisible Fat You’re Not Paying Attention To | Prof. Jimmy Bell
Q: What role do genetics play versus lifestyle in determining visceral fat, and can lifestyle changes meaningfully reduce it for most people?
Genetics accounts for a minority of variability; most of visceral fat distribution is driveable by lifestyle. Regular physical activity, resistance training, and caloric management can shift fat storage away from visceral depots, and preserve or increase muscle mass, improving metabolic health.
The Dangerous Invisible Fat You’re Not Paying Attention To | Prof. Jimmy Bell
Q: Why is visceral fat considered harmful beyond what BMI suggests, and how do we measure it accurately?
Visceral fat communicates with the rest of the body via adipokines and inflammatory signals, affecting liver, pancreas, and muscle function. MRI is the most accurate measurement; CT can also quantify it, but practical screening often relies on surrogate measures like waist-to-height ratio in conjunction with lifestyle assessments.
The Dangerous Invisible Fat You’re Not Paying Attention To | Prof. Jimmy Bell
Q: You're an expert in obesity and visceral fat—what are the different types of fat and which should people worry about most?
Visceral fat is the problematic fat that surrounds internal organs; subcutaneous fat is the fat just under the skin and has a more protective cardiovascular profile. The two have different signals and effects, with visceral fat being more strongly linked to metabolic risk, while subcutaneous fat can be more benign or even protective in certain distributions.
Are We Making Our Children More Allergic? | Prof Adam Fox
Q: Can adults alter their allergy risk later in life?
While early life is a critical window, there is still potential to influence the immune system in adulthood through interventions that affect the microbiome and inflammation, though effects may be smaller and more complex.
Are We Making Our Children More Allergic? | Prof Adam Fox
Q: Why is early exposure to allergenic foods important?
Early introduction of allergenic foods into the weaning diet helps the infant's gut recognize those foods as harmless, reducing the likelihood of an inappropriate immune reaction later on.
