With the Labour Day long weekend here, we’re bringing back one of our most popular Office Hours episodes on what really happens to your body when you take a break from alcohol. Whether you’re drinking less this weekend or simply curious about how quickly your body can recover, this conversation is worth revisiting.

Today I discuss:

• What alcohol really is—and why the “buzz” is actually your brain slowing down
• How alcohol affects neurotransmitters like GABA, dopamine, and glutamate
• Why even moderate drinking disrupts sleep, mood, hormones, and metabolism
• How alcohol impacts the liver, gut microbiome, immune system, and cancer risk
• Why hangovers feel like the flu—and what’s actually happening in your body
• What happens when you stop drinking, week by week, from detox to deep repair
• The surprising benefits to energy, focus, skin, sleep, and emotional resilience
• Practical tools to manage cravings, social pressure, and sleep disruption
• Why community support makes behavior change easier and more sustainable

Your body has an incredible ability to heal and often, it just needs you to take your foot off the gas. Try it for 30 days. You may be amazed by how different you feel. If you want extra support, join us for the Hive January Challenge, where we’ll guide you through the process, track progress, and share experiences together.

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.

The number on your scale tells you almost nothing about your actual health. You can lose weight while becoming less healthy—or stay the same weight while dramatically improving your metabolism, reducing your risk of disease, and adding years to your life.

In today's episode, I discuss:

• Why the scale can completely miss what's happening inside your body and the hidden health risks it can't measure
• The dangerous difference between muscle and visceral belly fat, and why one protects you while the other drives disease
• The five health markers I pay attention to instead of body weight—including one simple measurement you can do at home
• How insulin resistance develops years before diabetes and the early warning signs you can catch before it's too late

The goal isn't simply to lose weight; it's to build a healthier metabolism. The healthiest body isn't always the lightest one—it's the one that's functioning the way it was designed to.

Heart disease is still the leading cause of death worldwide. Yet many people assume it only happens to those who are older, out of shape, or obviously unhealthy.

In this episode, I sit down with cardiovascular surgeon Dr. Jeremy London, whose own heart attack challenged many of the assumptions we make about heart health. We discuss why prevention isn't always as straightforward as it seems—and how understanding your personal risk can help you take a more proactive approach to your health.

We cover:

• Why some healthy people still develop heart disease

• The difference between standard cholesterol tests and a more complete assessment

• How to better understand your personal cardiovascular risk

• The lifestyle changes that can help lower your long-term cardiovascular risk

What if one of the most powerful anti-aging tools wasn't a supplement, medication, or expensive biohack—but the way you exercise? While many people think of exercise as a way to lose weight or burn calories, its greatest benefits happen deep inside your cells.

In today's episode, I discuss:

• The two most effective forms of exercise for healthy aging and longevity
• What happens inside your cells when you challenge your muscles and cardiovascular system
• The often-overlooked factor that can determine whether you stay strong and independent as you age
• The minimum amount of exercise needed to support your muscles, metabolism, heart, and brain
• How and why you should measure your VO2 max

Healthy aging isn't about finding the latest longevity hack—it's about consistently giving your body the signals it needs to adapt, grow stronger, and stay resilient.
