You asked. Jonty Rhodes and Dr Marcus Ranney answered.

In this special 12th Man edition of Jonty & The Doc, we hand the conversation over to the audience for an Ask Me Anything covering everything from nutrition and strength to sleep, supplements, ageing — and, naturally, a little cricket.

What order should you eat the food on your plate? Is strength or coordination more important for longevity? Can you outrun a bad diet? Which health metrics are actually worth tracking? And what does Jonty look for when judging the fittest players in cricket?

In this episode:

• Does the order in which you eat your food actually matter?
  • How to reduce the glucose impact of a carb-heavy meal
  • Strength vs coordination for longevity
  • Why muscle matters far beyond aesthetics
  • The biggest fitness and longevity myths Jonty and Marcus want people to stop believing
  • Why you can’t “outrun a bad diet”
  • What Marcus thinks about Urolithin A and new longevity supplements
  • How Jonty’s relationship with competition has changed with age
  • Why Jonty now focuses on process rather than performance
  • The health metrics Jonty actually tracks
  • Why Marcus wishes we could track brain health more effectively
  • How their sleeping habits have evolved
  • Marcus’s 3–2–1 rule for better sleep
  • What “fitness” actually means inside an IPL team
  • The fielders who have impressed Jonty most over the years

It’s a slightly different Jonty & The Doc — driven entirely by the questions you want answered.

Erectile dysfunction is often treated as an embarrassing bedroom problem. But what if it’s actually telling you something important about your overall health?

In this episode of Jonty & The Doc, Jonty Rhodes and Dr Marcus Ranney have an open conversation about erectile dysfunction, why it becomes increasingly common with age and why men shouldn’t be afraid to talk about it. Marcus explains that ED can have vascular, hormonal, neurological and psychological causes — and in some cases may be an early sign of a larger health issue.

In this episode:

• Why erectile dysfunction becomes more common as men get older
  • The connection between ED and cardiovascular health
  • How diabetes, hypertension and high cholesterol can affect erections
  • What declining testosterone does to the male body
  • What andropause means
  • Why erectile dysfunction isn’t always about performance anxiety
  • The blood tests men can discuss with their doctor
  • Why men often hesitate to speak about sexual health
  • How sleep affects testosterone production
  • The relationship between body fat, testosterone and estrogen
  • Why strength training can naturally support testosterone
  • The role of nutrition, healthy fats and micronutrients
  • How smoking and alcohol affect blood vessels and sexual health
  • Why small, sustainable lifestyle changes can make a difference

As Marcus explains, four out of ten men over 40 experience some degree of erectile dysfunction — yet the stigma surrounding the subject means many men still avoid talking about it.

The important thing is not to dismiss it, self-diagnose or immediately reach for a quick fix. Get tested, speak to a medical professional and understand what your body might be trying to tell you.

Because sometimes a problem that shows up in the bedroom can be a window into what’s happening everywhere else.

What happens when you reach the stage of life where your body is changing, your children still need you — and your parents are getting older too?

In this episode of Jonty & The Doc, Jonty Rhodes and Dr. Marcus Ranney explore what they call “The Middle Zone” — the period where you find yourself balancing your own health, family, career and the growing responsibility of caring for ageing parents.

Jonty gets personal about the changes he’s noticed in his own body, losing his father and watching his mother live with dementia, while Marcus breaks down some of the practical steps we can take to protect our own health and help our parents age better.

In this episode:

• What “The Middle Zone” of life actually means
  • How our bodies begin changing as we get older
  • Why testosterone levels can decline with age
  • Why being physically fit doesn’t necessarily mean you’re healthy
  • The health checks we often put off for too long
  • The emotional reality of watching your parents grow older
  • Why movement, muscle and purpose become so important in later life
  • How Jonty saw his father’s mobility decline
  • Jonty’s experience of his mother living with dementia
  • Why protein and resistance training matter for ageing parents
  • What polypharmacy means and why medications should be reviewed
  • Why vaccinations become increasingly important with age
  • The conversation around creatine, NMN, NAD and other supplements
  • Simple ways to encourage ageing parents to move more
  • Why spending time with your parents matters just as much as helping them stay physically healthy

For many of us, there comes a point when the relationship with our parents begins to change. The people who once looked after us may gradually start needing our help instead.

And while we can’t stop ageing, there are things we can do — for ourselves and for the generation above us. As Marcus reminds us in this episode, it’s never too late to start.

Watch the full conversation and let us know in the comments: what’s one thing you’ve started doing differently as you — or your parents — get older?

What does it actually take to repair a damaged gut? Not vague advice - a real, structured protocol you can map onto your own life.

In this clip from Jonty & The Doc, Dr. Marcus Ranney walks through the 5R Framework for gut repair - a systematic functional medicine protocol - with Jonty applying each step to his own routine in real time.

The 5Rs:

Remove — eliminate what's actively harming the gut

Replace — restore what's been depleted: enzymes, stomach acids

Reinoculate — reintroduce beneficial bacteria through food and supplementation

Repair — rebuild and heal the gut lining itself Rest & Recovery— the most underrated step, and the one most of us skip entirely.

If you've been dealing with IBS, digestive sensitivity, bloating, or just know your gut isn't working the way it should - this framework is your starting point!
