The John Vincent Podcast
Fasting with Dr Ash Kapoor
My first guest on The John Vincent Podcast is Dr Ash Kapoor.
We talk about fasting – why you might want to try it, and what to expect when you do.
Dr. Ash Kapoor is a practicing clinician and a scientist with a deep curiosity about the human body, root cause analysis and a determination to understand what is happening at a cellular level.
Because Ash is going to be a regular here, we began with Ash’s view of the state of modern medicine, how you can become the owner of your own health, and how Ash’s career in medicine led to his fascination with regenerative medicine.
What will you learn from this episode?
- Dr Kapoor’s medical and personal background, his personal relationship to fasting, and his experiences training GPs within the NHS, and his subsequent research into regenerative medicine
- What fasting is, and when it might be beneficial to your body and mind.
- Both the biological and psychological process of fasting.
- Some surprising effects of fasting on your lifestyle and longevity.
- The ways to fast safely.
- A history of fasting in different cultures.
- The difference between fasting and starvation
- John’s personal experience of fasting under the guidance of Dr Ash, and his biomarkers before and after.
- Insight into how people with ADHD metabolise glucose differently.
At LEON, I wanted to provide people with delicious food that also allowed them to be healthy.
Now, Dr Kapoor has given me an additional way to think about our relationship with food that has deepened my own gratitude and mindfulness.
I have begun this exploration into ancient healing and modern medicine for the benefit of me, my family and YOU. It would make me so happy to hear what you think and what I can do better as in interviewer and learner.
Dr Kapoor will be a regular contributor to the podcast, so please give him a big welcome.
John

12. The Pivot to Prevention: 2 NHS Doctors Quit Their Jobs to Help You Put Health Back Into Your Own Hands
01:36:24||Ep. 12In this episode, I am lucky to have spoken to two doctors and pioneers in preventative medicine.Claire Merifield and Alasdair Scott were doctors in the NHS for years. But after being disillusioned by the medical system, they realised what their patients really needed was preventative, personalised healthcare. So they set up Selph, using their respective expertise to create a system with which they help people get to know their health profiles, risk factors, lifestyle and prevention opportunities through diagnostic testing and health coaching. Claire Merifield is a microbiome PhD, a London GP and a Breathworks Mindfulness instructor.Alasdair Scott is a microbiome scientist, former cancer surgeon in the NHS and a researcher with Imperial College.They cover:Why pivoting to prevention is urgent.Positive proactivity your future health - some of the diseases we think are ‘inevitable’ are actually preventable.Is the study of “medicine” the same thing as the study of “health”?Medicine 3.0: what it is, Lifespan vs health span and personalised medicine How to create achievable goals, avoid unattainable trends, and create environments in which you can access the health you have a right to. The current state of health advice: influencers and scaremongeringEvidence-based vs evidence-informed approaches (there’s an important difference)Understanding testing and diagnosticsWhat counts as ‘safe’ treatmentsThe role of emotional and spiritual health, mindfulness, and the gut in physical wellbeingI’m so grateful to Claire and Alasdair who made a brave leap to do the right thing for us, even if it takes a lot of hard work and re-wiring of how we, as a population, are taught to think about our health.

10.4. (Pt. 4) How Your Mind Will Heal You (if it knows what to fix) with Dr. Leo Pruimboom
30:22||Ep. 10.4This is the final part of my episode with Dr Leo Pruimboom, a pioneer in cPNI. I was incredibly lucky to speak with him at the 2025 Integrative and Personalised Medicine Congress. Our conversation offered me a new understanding into how much health we can have access to if we know how to truly sense what our bodies are telling us, and how to manage the consequences of modern inventions. His personal story of transformation, and healing anecdotes from his clients will allow you to imagine a life full of possibility and ‘miracles’ that we are not typically taught to believe in.Clinical Psychoneuroimmunology (CPNI) challenges the reductionist, symptom-focused model of modern medicine. Instead, CPNI is a science of wholeness: it studies how the neurological, endocrine, immune, and metabolic systems are interconnected and shaped by our emotions, history, and environment. CPNI puts the individual at the center of healthcare, seeking root causes, promoting healthy habits, and empowering patients to actively participate in their own wellbeing.In this episode we cover:How CPNI (clinical psychoneuroimmunology) reveals that everything is connected—mind, body, brain, immune system, and environment.How we’ve been taught to see systems as separate and why that reductionism isn’t serving us.The impact of emotions on physical health, inflammation, and immunity.Do toxic emotions exist?How to sense what out bodies need and why modern life makes this hardComfortable habits vs challenges that make us healthy.Why variety, spontaneity, and movement breaks protect our health.What our cravings mean, hunger and micronutrient sensing.Why intermittent fasting, ketosis, and diets must be understood in context, not as dogma.How our environment shapes our microbiome.The role of energy, frequency, and electrical signaling in health.The difference between appropriate and inappropriate emotions.Why monotony is dangerous for our health and variety is medicine.His seemingly miraculous healing stories, and how processing a childhood trauma cured his lifelong condition in hours.The role of sensing, intuition, and embodied intelligence.Why the blueprint of life isn’t in our genes—it’s in our behavior, context, and choices.How our inventions (from chairs to supermarkets) carry unintended health consequences—and how to deal with them.How we are more in charge of our health than we think.Why the doctor’s role is shifting.(The information provided in this podcast is intended for informational purposes only and does not constitute medical advice.
