The Long Game | Dr Alex

Your grandmother's kitchen in 1955 had a loaf of bread that took most of a day to make and cabbage sitting in a jar of brine. Your kitchen this morning probably has sliced white bread with a list of emulsifiers and preservatives longer than your hand.

In this episode I go through six things that have changed in our food environment since around 1950 that help explain why IBS has become so common. These include how bread is made now compared to then, our disappearing fibre intake, the rise of emulsifiers in processed food, the loss of fermented foods from our diets, the impact of antibiotics on gut bacteria, and the way stress and rushed eating affect gut function.

I also cover two common mistakes people make when trying to sort out their gut health themselves, including cutting out gluten before getting properly tested and misusing the low FODMAP diet.

Imagine there were no doctors, no A&E, no statins, no insulin. Would you still make the same choices every single day?

In this episode I talk about why the NHS was built to handle fast problems like infections, injuries and childbirth, and why it now spends most of its time trying to hold back slow problems like heart attacks, type 2 diabetes and fatty liver disease that take decades to build.

I go through why ultra processed food is engineered to be hard to stop eating, what a tightly controlled feeding study found when people switched between processed and whole food diets, and why a diagnosis often comes with a tablet but very little education about what actually caused the problem in the first place.

I also share what a real world weight management trial found when people diagnosed with type 2 diabetes were given structured support alongside their usual GP care, and why small daily choices matter so much more than they feel like they do in the moment.

After a decade in emergency medicine, Dr Alex noticed something odd. The age on the computer screen and the age on the trolley are often two completely different things. Some patients in their 80s felt decades younger than their notes suggested, while others much younger had become frail before their time.

So what are the people who age well actually doing differently? In this episode Dr Alex shares four habits he has noticed again and again over years of shift work, none of which involve a supplement or a special diet. He talks through staying curious, processing setbacks instead of ruminating on them, thinking critically about health claims, and having a reason to stay well, a sense of purpose that pulls you through the day.

He is upfront that these are his own clinical observations rather than a formal study, but he backs each point up with research where he can, including work on neuroplasticity, cortisol and chronic stress, and large studies linking a sense of purpose to heart health and memory in later life.

A flight of stairs tells you more about your heart than most tests done while you're sitting still. In this episode I lay out one heart focused job for each day of the week, from walking and strength work to checking your blood pressure and going through your supplement cupboard.

None of these individual days will fix anything on their own. The point is repeating the whole week for years, not finding one magic habit.

30 plants a week sounds impossible until you realise it is not 30 big portions of veg. Fruit, nuts, seeds, beans, lentils, whole grains, herbs and spices all count, and once you add those up the number becomes far more achievable than it first sounds.

This target comes from one of the largest studies ever done on the human gut, which found that plant variety, not whether people ate meat, took probiotics or exercised, was the single strongest predictor of a healthy, diverse gut microbiome.

Variety matters because different types of fibre feed different species of bacteria. Stick to the same few foods and only a narrow slice of your gut bacteria get fed. Widen your plants and you feed the whole system, which helps your gut produce compounds like butyrate that fuel your gut lining, support your appetite hormones and help keep that gut barrier tightly sealed.

There is also a simple swap effect at play. Every plant you add tends to push something ultra processed out of your day, since a handful of nuts or a tabbouleh salad fills you up in a way a meal deal never will.

In this video I explain where the number 30 actually comes from, what your gut bacteria do with all that variety, and simple low effort ways to build towards it without going vegan or overhauling your entire diet.

Try this. Stand up out of your chair without using your hands. That simple movement is one of the better predictors of how the next 20 years of your health will go, and the good news is that it can be trained.

As an NHS emergency medicine doctor, I spent years treating falls and fractured hips that traced back to muscle that had been quietly disappearing for decades with nobody noticing. The trial I mention in this video followed frail nursing home residents in their late 80s, many using sticks or Zimmer frames. After just 10 weeks of proper resistance training, their strength more than doubled, their walking speed improved and their thigh muscle visibly grew on scans. A nutritional drink alone did almost nothing.

In the full video I cover why so many people train for months and see no change, the small adjustment to how you move that matters more than raw strength, the mindset shift that decides whether you keep this up in 10 years, and the two quieter factors working underneath all of it.

Two people walk into clinic with the same painful knee and the same scan results. One is in pain most days. The other barely notices it. The difference very often has nothing to do with the joint itself and everything to do with what has been happening in their blood and on their plate for years.

To be clear, you cannot eat your way out of arthritis and no single meal will regrow cartilage. But the pain you feel and the damage on a scan are two different things, and inflammation is a big part of the gap between them.

In this episode I cover why acute and chronic joint pain need completely different approaches, what inflammation is actually doing inside a joint, why visceral fat behaves like an organ that signals straight to your knees, which foods turn that signalling up or down, and what the trial evidence actually shows.

This is general education, not a replacement for being examined and diagnosed properly. If your pain is new, severe, in one hot swollen joint, or comes with fever or weight loss, that needs a same day assessment rather than a diet plan.

Diet or exercise, which one actually keeps you alive longer?

I've spent years thinking about this question, and after a decade in emergency medicine I think I finally have an answer worth sharing.

In this episode I walk through the strongest trial we have on diet alone (a Mediterranean pattern cut heart attacks, strokes and deaths by around 30 percent, with nothing else changed), then the strongest evidence on exercise alone (hitting 150 minutes a week was linked to a similar drop in risk of dying, and even half that amount still helped a lot).

Both sides have genuinely solid evidence behind them. What tips it for me personally comes from the pattern I kept seeing on shift after shift, which points towards insulin resistance sitting underneath most of the chronic disease I treat.

I explain why that pushes me towards food as the foundation and movement as something that builds on top of it rather than the two competing for a crown.

Forget 10,000 steps. If you are currently doing next to nothing, the jump from where you are now up to around 5,000 steps a day will do more for your health than almost anything else I could ask of you.

When researchers pooled together huge studies following tens of thousands of people for years, the curve was steepest right at the bottom. Going from around 2,000 steps up to 4,000 or 5,000 produced the single biggest drop in risk of dying from anything, across the whole range. After that the line keeps improving but it starts to flatten off, so every extra thousand steps buys you a little less than the one before.

There is a study I think about often. Researchers took very active young people walking around 10,000 steps a day and asked them to drop down to just 1,500 steps for two weeks. In that short window their blood sugar control got measurably worse, their insulin stopped working as well, fat gathered around their middle and their fitness dropped off. When they started moving again, a lot of it reversed.

That is because your muscles are the biggest sugar disposal system you own. Every contraction pulls sugar straight out of your bloodstream without needing to wait for insulin. A body that walks clears sugar out of the blood all day long, and persistently high blood sugar underpins so much of the chronic disease we see.

Walking also helps lower blood pressure through something called shear stress, where faster blood flow against the lining of your arteries triggers the release of nitric oxide, your body's own blood pressure medication, which relaxes and widens the vessel walls.

Then there is your brain. Moving your muscles releases chemical messengers that prompt your brain to produce more BDNF, a kind of fertiliser for brain cells that supports mood and memory. Some trials have even found that regular walking can work as well as medication for milder depression.

I just finished my final run of night shifts in the A&E and I cannot stop thinking about what I saw.

Four nights in a row, roughly 120 patients in total. Two of those shifts were in resus, where the sickest people in the hospital end up. Heart attacks, cardiac arrests, sepsis, heart failure.

For the first time ever I wrote down the reason every single patient was in front of me that night, leaving out anything identifiable. When I looked at the full list at the end of the week, one thing hit me hard.

Out of around 120 people, every single one except one was there with something that could very likely have been prevented if something had changed years earlier.

Heart attacks. Strokes. Falls linked to muscle that had wasted away over the years. Amputations from type two diabetes. Kidney failure. Heart failure. The same small group of conditions coming through the doors again and again, often in people younger than you would expect to be facing any of this.

This is not a criticism of those patients. It is a reflection of a system built to patch people up once they break rather than help them avoid breaking in the first place, and of a modern life that quietly pushes all of us away from the basics that keep us well.

I also tell the story of the one patient on that list who could not have been prevented by any lifestyle change at all. A four year old girl who had swallowed a button battery. It was the hardest shift of my career and I explain in the video why every parent needs to know how dangerous these batteries are.
