  • 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.

Are Microplastics Really Making Us Sick? | Dr Stephanie Wright
Q: Are microplastics really the worst offender, and what would be even worse than that?
Wright says heating food in plastic can increase particle exposure, although the particles' exact nature is not always clear. She also points to plastic in tea bag seals and tire wear particles in air, especially near busy roads.
Are Microplastics Really Making Us Sick? | Dr Stephanie Wright
Q: At this point in time, what do we actually know about the human health impact of microplastics?
Wright says evidence about human health effects remains limited. People are likely exposed regularly, but research faces major challenges measuring particles in the body and determining what they do.
The Hidden Link Between Menopause And Gut Health | Cynthia Thurlow
Q: Can you tell us what's happening in the body that causes these mental changes and increases in issues like anxiety and brain fog?
Thurlow explains that progesterone and estradiol influence neurotransmitter systems, while gut inflammation and signaling through the vagus nerve can affect the brain. Hormonal shifts, gut health and lifestyle factors can combine to influence anxiety, depression, irritability and brain fog.
The Hidden Link Between Menopause And Gut Health | Cynthia Thurlow
Q: Why does gut health suddenly become so important for women, specifically after 40?
Thurlow says declining progesterone and estradiol can affect gut motility, inflammation, intestinal permeability and metabolism, contributing to digestive symptoms and microbiome changes. She adds that earlier-life exposures and experiences also shape gut health before perimenopause.
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.
