Feel Better, Live More with Dr Rangan Chatterjee

Could the food you ate yesterday already be reshaping your gut, your immune system and your risk of chronic disease? This week’s guest says yes, and he’s spent his career demonstrating why that matters so much.

Dr Will Bulsiewicz is an award-winning gastroenterologist and the author of the new book, Plant Powered Plus. And few people can explain the science of gut health as clearly, or as compassionately, as Will does in this conversation. If you think you already know everything there is to know about digestion, fibre and plant foods, this episode will change your mind – and deliver a great deal more.

Will has identified four nutrition ‘workhorses’ that feed and protect our guts and, unsurprisingly, fibre is one of them. We get into the specifics of how the fibre we eat turns into short-chain fatty acids like butyrate, which Will describes as the most anti-inflammatory substance he has ever come across. He makes the case for fibre as the true longevity nutrient. We talk about resistant starch, found in cooled potatoes and green bananas, and why it feeds a completely different part of your gut microbiome to other fibres. Will shares the research behind the ‘30 plants a week’ target, and why he thinks the exact figure matters far less than most people assume. And he covers the importance of polyphenols, healthy fats and fermented foods.

There’s a fascinating section on the different ways our gut microbiomes are shaped by our closest relationships, including some research findings even Will found surprising. We bust some myths around the term ‘leaky gut’. And we discuss why he no longer sees Crohn's disease and ulcerative colitis as straightforward autoimmune conditions, but more like the immune system turning against the microbiome.

Will is refreshingly honest about the limits of diet alone. He talks candidly about the patients he could not help through nutrition or medication, and about a period in his own life when food became a coping mechanism for something he wasn’t able to face. It is a reminder that lasting health often asks more of us than simply eating better.

Whether you’re new to the topic of gut health or well acquainted, this episode brings a new perspective. It’s packed with valuable and actionable moments – and it’s one you’ll come back to again and again.

When we think about improving our health, we often think about changing our diet, increasing how much we move, improving the quality of our sleep and lowering stress, but how many of us think about ‘working’ on our vision?

Every day, many of us experience symptoms like brain fog, fatigue, headaches or poor concentration – and never realise that our eyes might be playing a central role.

In today’s Bitesize, pioneering neuro-optometrist Dr Bryce Appelbaum explains why our visual system is about far more than simply how well we can see. Many of us don’t realise just how much our vision influences how we think, feel and perform.

We explore the surprising connection between vision and stress, and Bryce shares some simple, practical exercises we can all use today to better support our visual system and our wider health.

Why does struggling for something make it more satisfying? And why can getting what you want leave you feeling flat? In this episode, I sit down with Arthur Brooks, one of the world's leading voices on the science of happiness, for a conversation that might change how you feel about your life.

Arthur is a professor at Vanderbilt University, senior fellow of Harvard Business School and bestselling author of multiple books, including new title, The Meaning Of Your Life. He walked away from a successful career when he realised that despite a happy marriage, strong faith and good income, he struggled to feel happy. That personal reckoning led him to years of research into what really makes people thrive – and in this conversation, he shares the framework he developed to explain it.

Using an analogy from nutrition science, Arthur describes happiness as requiring three macronutrients: enjoyment, satisfaction and meaning. We talk about why so many high achievers get the first one wrong. Suffering and struggle, he says, aren’t obstacles to a fulfilling life but essential ingredients of it – hence removing all friction from our lives can leave us feeling empty rather than content.

We also get into goals, and why reaching them tends not to deliver the lasting happiness we expect. Arthur calls this the arrival fallacy, and understanding might change how you approach your next big challenge.

On relationships, Arthur shares research showing that the healthiest marriages are not the ones with the least conflict, but the ones with the most honesty. We talk frankly about what that has looked like in our own marriages, what we can all learn from our parents when it comes to happiness, and the best (and easiest) way to send a positive message to our children. Arthur also shares what he’s learned about presence, faith and love from his relationship and his daily practices.

We explore the difference between solitude and loneliness and how levels of social connection can be individual. And I hope you’ll pay attention to the section on why leisure needs to be treated as seriously as work.

This is a warm, honest and personal conversation with someone who’s spent decades studying happiness – but who’s candid about how hard he’s worked to feel it himself. By reframing happiness as a direction not a destination, I think it could be a life-changing listen for you.

Most of us assume that memory loss and cognitive decline are just part of getting older. In this episode, a world-leading neurologist says that’s simply not true. That, far from being inevitable, Alzheimer's and other neurodegenerative diseases result from decades of metabolic damage – which we have the power to prevent and even reverse.

I’m speaking with Dr David Perlmutter, a board-certified neurologist, six-time New York Times bestselling author, and one of the world's leading experts on brain health. And in this fascinating conversation, we discuss the single biological mechanism that sits at the heart of virtually every neurodegenerative condition, from Alzheimer's and Parkinson's to long Covid and depression, and why understanding it changes everything about how you approach your lifestyle.

David’s key insight is that our brain's own immune cells, called microglial cells, have the power to make or break our future brain health. Keep them in their protective state through diet, exercise, and metabolic testing, and we can safeguard our brain for life. Feed them with ultra-processed food and they will shift into a destructive state that drives neuroinflammation.

We discuss how, exactly, ultra-processed food damages the brain, why metabolic health is the key to cognitive longevity, and why the diagnosis of Alzheimer's is really the end stage of a process that began decades earlier. The choices you make right now, in your 30s, 40s and 50s, are already shaping the brain you will have in your 70s and beyond.

If this all sounds science-heavy, rest assured David approaches it, just as he does in his new book, Brain Defenders, with clarity and plenty of practical takeaway. He outlines the specific blood biomarkers he believes everyone should be tracking, including fasting insulin, homocysteine and uric acid, for a remarkable window into your long-term brain health. We discuss why knowing your numbers is one of the most empowering steps you can take, how to go about getting tested, and how to act on what you find.

There is a great deal of fear around dementia, and understandably so. But what I hope you take from this episode is something David emphasises: we needn’t be scared because we have agency. The research is clear that lifestyle choices have a profound impact on your risk, and it is never too early, or too late, to start making them.

This is one of the most distinct and important conversations I’ve had about the future of your brain, and I think you will find it incredibly useful, thought-provoking and, above all, hopeful.

As we get older, have you ever wondered why the exercise advice we’ve been given doesn’t seem to work as well as it once did? As we move into our 40s and beyond, our physiology changes in ways that can often feel confusing and frustrating. But what if we could harness those changes to feel stronger, healthier and more resilient than ever before?

Feel Better Live More Bitesize is my weekly podcast for your mind, body, and heart. Each week I’ll be featuring inspirational stories and practical tips from some of my former guests.

Today’s clip is from episode 578 of the podcast with exercise physiologist and nutritional scientist, Dr Stacy Sims.

Stacy is dedicated to helping active women – and the people who support them – take back control of their bodies, health and lives through science-based knowledge and practical tools.

In this clip, Stacy shares why conventional fitness advice often fails women in midlife, and what many of us may be missing when it comes to improving our health, vitality and resilience as we age.

Stacy’s insights remind us that with the right information and support, we can build strength, confidence and better health at any stage of life.
