Nutrition advice often reduces food to calories, nutrients, and a list of rules to follow. But the more we learn about how the body responds to different foods, the clearer it becomes that this way of thinking tells only part of the story. Today, I’m joined by cardiologist and public health expert Dr. Dariush Mozaffarian, director of the Food is Medicine Institute at Tufts University and author of the new book Food Is Medicine. We explore what we still get wrong about food and what changes when we begin treating it more like medicine. Here’s what we discuss: Why eating less and exercising more may not lead to lasting weight loss, and what to focus on instead How to choose foods that work with your appetite, metabolism, and microbiome rather than relying on calorie counting What GLP-1 medications can teach all of us about hunger, cravings, and why weight isn’t simply about willpower How much protein you actually need and why the source matters What the science says about seed oils and which processed foods are worth avoiding Over the years, I’ve learned to focus less on counting calories or chasing a single nutrient and more on the quality of the food itself. When you eat real, whole foods, the signals that regulate hunger and energy can begin to work with you instead of against you. Eating well should be less about following rules and more about understanding what helps your body function at its best.

In this episode, I break down five popular longevity myths that may be distracting you from the things that actually have the biggest impact on how long and how well you live. Here’s what I discuss in today’s episode: The common longevity goal that may actually work against you as you get older Why the “perfect” supplement stack can’t replace the habits that matter most The mistake people make when they try to keep their body in constant repair mode What the science really says about red wine, genetics, and the factors that shape how you age Longevity isn’t about building the world’s most complicated routine.

You can know exactly how you want to eat and still find yourself reaching for something else when you’re stressed or exhausted. I’ve been there. Our relationship with food is influenced by far more than nutrition knowledge, and blaming ourselves for struggling doesn’t help us understand what’s actually happening. Today, I’m joined by clinical psychologist Dr. Rachel Goldman, author of When Life Happens, to talk about the biology and psychology behind cravings, emotional eating, and food noise. We also explore how to care about nutrition without letting food rules take over your life. Here’s what we get into: Why you may reach for food when what you really need is rest, comfort, or a break How to pause before an automatic food choice and figure out what’s driving it How rigid food rules can turn one choice into a cycle of guilt and overeating How GLP-1s can quiet food noise, and what they can’t change about your relationship with food How to build other ways to cope when food has become your go-to response to stress I know what it’s like to want the cookie even when I know it isn’t what I really need. Knowing better doesn’t make us immune to being human. My hope is that this conversation helps you meet those moments with more curiosity and less blame, so your relationship with food can become a source of nourishment rather than stress.

Trying to eat healthy has gotten surprisingly complicated. You pick up salmon and wonder about mercury, grab strawberries and think about pesticides, or drink from a plastic bottle and start worrying about microplastics. But not every food-safety risk deserves the same level of concern. In this episode, I break down what actually matters, what’s worth paying extra for, and the simple changes that can reduce your exposure without making you afraid of everything you eat. Here’s what I discuss in today’s episode: Which food-safety risks actually deserve your attention—and which ones may be creating more fear than necessary How to think about organic produce, pesticides, recalls, and foodborne outbreaks without avoiding healthy foods altogether What labels like grass-fed, organic, pasture-raised, wild-caught, and farm-raised really tell you—and what they don’t The hidden exposures that can come from packaged foods, plastics, cookware, and even common mistakes in your own kitchen Food safety isn’t about eliminating every possible risk. It’s about knowing which risks matter, understanding where small changes can make a meaningful difference, and having enough good information to separate a real concern from a scary headline.

Chronic illness rarely fits neatly into a single diagnosis. Symptoms can span multiple systems, leaving people profoundly unwell even when standard testing appears normal. I understand this experience from the inside out because I’ve lived it myself. Today, I sit down with Dr. Neil Nathan, a leading expert in complex chronic illness and author of Toxic, now in its second edition. We explore why these conditions are so often misunderstood and how identifying what is driving them can create a path toward recovery. We discuss: Why mold toxicity, Lyme disease, and long COVID can be so difficult to diagnose How to identify the root cause instead of chasing downstream symptoms What the Cell Danger Response is and why the body can remain stuck in survival mode Why some people suddenly become sensitive to foods, chemicals, medications, light, and sound Why the right treatment can make symptoms worse when introduced at the wrong time I’ve been sick enough to know how quickly chronic illness can narrow your world—and how discouraging it is when no one can explain why. But I’m also living proof that the body can recover. The answer is not always more treatment. Often, it begins with finding the root cause, respecting what the body can tolerate, and addressing each layer in the right order.

Brain fog isn’t just a normal part of getting older—and it may not be a brain problem at all. If you struggle to focus, lose your train of thought, forget why you walked into a room, or feel mentally exhausted after eating, your body may be trying to tell you something. Here’s what I discuss in today’s episode: The five foods I most commonly see contributing to brain fog—and why some seemingly “healthy” choices may be working against you The surprising connection between your gut and your ability to think, focus, and remember Why certain foods can affect your brain even when you don’t have obvious digestive symptoms Brain fog is a messenger, not the root problem. When you start looking at what’s happening throughout your body—especially your gut, blood sugar, inflammation, and microbiome—you can begin uncovering what’s getting in the way of a clearer, healthier brain.

This week, I’m the one answering the questions in a deeply personal conversation about my health journey. I speak openly about some of the hardest parts of that journey, the treatments I’ve tried, the beliefs I’ve reconsidered, and what a lifetime devoted to health has taught me about what matters most. Here’s some of what I share: How becoming the patient changed the way I practice medicine How nearly dying changed what longevity means to me and what I believe a healthy life is actually for Which wellness and longevity therapies I personally use, and how I decide what’s worth trying Why the pursuit of optimal health can sometimes become unhealthy What I’m still trying to understand about myself at this stage of my life I’ve spent much of my life trying to understand how we can live longer and feel better. But nearly losing my own life reminded me that health isn’t the destination. It’s what allows us to be present for the people we love, remain curious, and experience our lives more fully. I hope this conversation encourages you to ask yourself what you want your health to make possible. Continue exploring: Watch my conversation with Dr. Tyna Moore here.

We hear a lot about improving gut health through food, probiotics, and supplements. But after more than a decade of major advances in microbiome research, the picture has become both more promising and more complex. In this episode, I’m joined by gastroenterologist and neuroscientist Dr. Emeran Mayer, co-author of the new book The Mayer Model, to explore how our understanding of the gut-brain connection has evolved—and what we may still be getting wrong. We also look at what this growing field could mean for chronic disease and healthy aging. Here’s what you’ll learn: How your gut microbiome communicates with your brain, immune system, hormones, and metabolism Why diet alone may not be enough to improve gut health—and how sleep, stress, exercise, relationships, and purpose also shape your microbiome How modern diets and lifestyles have created a mismatch between our microbes and human biology Why probiotics and microbiome testing may not provide the personalized answers many people expect How fiber, polyphenols, fermented foods, and greater plant diversity help support a healthier, more resilient microbiome The food we eat matters, but so do the ways we move, sleep, manage stress, and connect with others. Supporting gut health isn’t about finding one magic solution. It’s about creating a healthier, more resilient system over time. Beginning September 1, Dr. Mayer’s team is offering my audience a collection of bonuses to accompany The Mayer Model. To learn more about the book and access the bonuses, click here.

ADHD is usually treated as a problem in the brain. But what if some of the factors making it harder to focus, regulate your mood, or manage your symptoms are actually coming from somewhere else in your body? In this episode, I’m joined by one of my producers, Emma, to explore ADHD through a functional medicine lens. We look beyond the diagnosis to ask what may be happening “under the hood”—from the gut and microbiome to inflammation, nutrient deficiencies, blood sugar, hormones, and the foods we eat. Because the brain doesn’t operate in isolation. What happens throughout the body can directly influence how it functions. Here’s what we discuss in today’s episode: The surprising connection between your gut and your ability to focus—even if you have no digestive symptoms What I look for beyond the brain when someone comes to me with ADHD The everyday foods and nutrient deficiencies that may be quietly making ADHD symptoms worse Why two people with the same ADHD diagnosis may have completely different underlying drivers What caffeine, skipping breakfast, food dyes, sugar cravings, and menopause may mean for ADHD symptoms Where I would start if an adult came to me newly diagnosed with ADHD ADHD may begin with symptoms in the brain, but that doesn’t mean the brain is the only place we should look. By understanding the connections between diet, gut health, inflammation, nutrients, hormones, and brain function, we can start asking a more useful question: What is making it harder for each person’s brain to function at its best?

ADHD can go unnoticed for decades, especially in women who learn to compensate through perfectionism, overpreparing, and working under pressure. It often isn’t until the demands of work, motherhood, or another major life transition become too much that the underlying struggle comes into view. In this episode, I sit down with ADHD counselor Jenna Free, author of The Simple Guide to ADHD Regulation, to explore what she calls the frantic-crash cycle. She explains how chronic fight-or-flight may intensify ADHD symptoms and why nervous system regulation can make other tools and strategies easier to use. You’ll learn: Why women and high achievers can compensate for ADHD for decades before their usual coping strategies stop working How perfectionism, procrastination, and working under pressure can keep the frantic-crash cycle going The physical signs of nervous system dysregulation, including shallow breathing, muscle tension, and rushing even when there’s no real urgency Why calming your body is only the first step in creating lasting change How you can move away from all-or-nothing behavior and build a more sustainable way of getting things done A diagnosis can help you understand how your brain works, but it doesn’t have to define what’s possible. By learning to recognize and regulate survival mode, you can create the conditions for your brain to work at its best.

Chronic inflammation may be one of the biggest forces accelerating how we age—and the surprising part is that many of the things keeping it switched on are happening every day. Poor sleep, chronic stress, blood sugar spikes, visceral fat, and ultra-processed food can keep your immune system acting like it’s under constant threat, potentially contributing to everything from metabolic dysfunction and heart disease to arthritis and cognitive decline. Here’s what I unpack in today’s episode: The hidden “inflammation switch” scientists are studying and why it may help explain how chronic inflammation drives aging and disease The everyday habits that can keep your immune system stuck in a constant state of alarm The surprising connection between mitochondrial health, visceral fat, blood sugar, and inflammation The most effective ways to help calm chronic inflammation and the simple daily shifts that may have the biggest impact Inflammation isn’t the enemy—it’s one of your body’s most important survival tools. The problem is when the alarm never switches off. By changing the signals you send your immune system every day, you can help restore balance and support healthier aging from the inside out.

By the time memory begins to slip, the changes affecting the brain may have been developing for decades. But the trajectory isn’t fixed, and many of the factors driving it are within our control. In this episode, I sit down with my longtime friend and mentor Dr. David Perlmutter, six-time New York Times bestselling author whose new book, Brain Defenders, rethinks what it really takes to protect the brain as we age. You’ll learn: Why protecting your brain should begin long before memory problems appear How your daily choices influence whether the brain’s immune cells shift into a protective or damaging state Which numbers to know now, including fasting insulin, blood sugar, and waist-to-hip ratio How food, exercise, sleep, gut health, and environmental toxins shape your brain’s future What emerging research reveals about slowing—and even improving—cognitive decline I’ve always appreciated how David’s work replaces fear with something far more useful: a clearer understanding of how the choices we make today can help protect our memory, independence, and quality of life for years to come.

Healthy skin isn't built in your bathroom—it’s built inside your body. While most people focus on creams, collagen powders, and cosmetic treatments, the biggest drivers of wrinkles, sagging, and loss of elasticity are happening at the cellular level. In today's episode, I discuss: Why blood sugar may be aging your skin faster than the sun and the hidden process that damages collagen from the inside out The surprising connection between muscle, metabolism, and firmer, healthier-looking skin (especially after weight loss) How your body's natural cellular repair system helps slow the aging process and the habits that activate it The biggest everyday factors accelerating skin aging, and the science-backed strategies that help protect your skin for years to come Healthy skin isn't something you can simply apply—it's something your body creates. By improving your metabolic health, protecting collagen, building muscle, reducing inflammation, and supporting your cells, you can help your skin stay stronger, healthier, and more resilient from the inside out.

GLP-1 medications have changed how we treat obesity and metabolic disease. But as their use has exploded, so have questions about side effects, muscle loss, long-term use, and whether patients are receiving the support they need to use them safely. In this episode, I reconnect with metabolic health and regenerative medicine expert Dr. Tyna Moore to revisit our conversation from two years ago and examine what we’ve learned since. We discuss: How to tell when your GLP-1 dose may be too high What you can do to protect your muscle and bone during weight loss Which metabolic and nutritional markers should you check before and during treatment Why weight can sometimes return after stopping a GLP-1 What emerging research suggests about GLP-1s beyond weight loss GLP-1s can be life-changing, but a lower number on the scale isn’t the same as better health. Ultimately, how these medications are used—from dosing and monitoring to nutrition and strength training—matters just as much as whether they’re used at all.
