In this episode of The Habit Healers Podcast, Dr. Laurie Marbas takes you inside the mind of a physician with a powerful clinical vignette designed to uncover the real, often-overlooked roots of persistent brain fog and unrelenting fatigue.

You’ll meet a 47-year-old woman who feels like she’s “wading through molasses”—struggling to think clearly, waking up exhausted, and slowly losing control of her energy. Her story mirrors the experience of millions, but the cause isn’t as simple as stress, age, or “being busy.”

Dr. Marbas walks you step-by-step through the diagnostic reasoning process:

* How physicians think through uncertainty

* The key clues that matter most in cases of fog + fatigue

* Why a cluster of symptoms tells a deeper story than any single complaint

* How sleep disruption, insulin resistance, stress physiology, and midlife hormonal shifts can intertwine to cloud the brain

You’ll also learn the surprising lifestyle patterns that quietly sabotage clarity—late-night screen time, skipped breakfasts, fragmented sleep, evening carb surges—and why women in midlife are especially vulnerable.

Most importantly, this episode highlights what actually helps:

* Rebuilding sleep architecture

* Giving the brain steady, predictable fuel

* Simple post-meal movement that sharpens afternoon focus

* Restoring daily light and stress rhythms

* Identifying when symptoms signal something more serious

This isn’t about guessing or self-diagnosing. It’s about learning to see your health through a more connected, compassionate lens—one that empowers you to ask better questions and make changes that really move the needle.

If brain fog and fatigue have become your “new normal,” this episode will help you understand why—and what small, repeatable habits can begin to turn things around.

Clearer thinking and better energy aren’t luxuries—they’re signals your brain can thrive again.

In this eye-opening episode of The Habit Healers Podcast, Dr. Laurie Marbas unpacks one of the most misunderstood truths in modern health: you can be overweight, overfed, and still profoundly undernourished.

Through stories, science, and global insights, Dr. Marbas explains the health paradox unfolding worldwide—where obesity and nutrient deficiency often exist in the same body. From South African children who appeared well-fed but were lacking essential nutrients, to the millions of adults in the U.S. who consume plenty of calories yet remain low in vitamin D, magnesium, fiber, or iron—this episode reveals why “eating enough” no longer means “being healthy.”

You’ll learn:

* Why malnutrition isn’t about calories—it’s about the quality of those calories

* How ultra-processed foods create “hidden hunger” even when the stomach is full

* The real-life signs of nutrient deficiencies: brain fog, fatigue, brittle nails, mood changes, digestive issues, sugar cravings, and more

* The deeper structural forces—cost, access, marketing, culture—that shape the modern food landscape

* Why the “double burden of malnutrition” is rising globally, affecting families, communities, and entire countries

* How nourishing your body with whole, nutrient-dense foods creates a foundation for healing, energy, and resilience

This episode is not about guilt, restriction, or blame. It’s about understanding what your biology truly needs—and how even small, consistent upgrades can shift your energy, metabolism, and long-term health.

If you’ve ever wondered why you’re tired despite eating enough, why cravings won’t let up, or why changing your diet hasn’t “worked” before, this conversation offers clarity, compassion, and a path forward.

When you nourish better, you feel better. Your body already knows how to heal—you just need to give it the right materials.

In this episode of The Habit Healers Podcast, Dr. Laurie Marbas uncovers one of the most underestimated drivers of insulin resistance: stress—and the cortisol spikes that come with it.

We often blame food, age, or a busy schedule for our fatigue and cravings, but the real story is deeper. Dr. Marbas breaks down how everyday stressors—traffic, lack of sleep, overflowing inboxes, even skipped meals—activate an ancient survival system that quietly raises blood sugar, intensifies cravings, disrupts sleep, and exhausts your metabolism.

You’ll learn:

* How cortisol actually works and why modern life keeps it elevated

* The subtle sources of stress that trigger blood sugar spikes

* Why stress can feel like sudden hunger or uncontrollable cravings

* The hormonal cascade linking stress → sugar → insulin → energy crashes

* A simple, powerful micro habit—the 4-7-8 breath—that helps slow the cycle and retrain your nervous system

* When stress signals a deeper issue worth discussing with a provider

Dr. Marbas also walks you through a weekly micro habit plan you can start today, plus reflection prompts to help you recognize your stress patterns and regain metabolic control.

If you’re looking for a practical, compassionate way to calm your body, steady your blood sugar, and build trust in your metabolism again, this episode is your starting point.

Thank you Rob Tourtelot, Teresa and many others for tuning into my live video with Chef Martin Oswald!

Tonight’s Transatlantic Cooking Session: What This Meal Can Do for Your Heart

Tonight’s live was a true two-continent collaboration.Chef Martin cooked from Austria. I joined from the U.S.He brought the skill and flavor; I brought the physiology behind why this meal works so well for metabolic and cardiovascular health.

He made a porcini mushroom barley risotto layered with kale, along with a fresh kale salad topped with red onionsand sunflower seeds. He’ll be sharing the full recipe soon. He also walked through several ways to make homemade vegetable stock — a simple upgrade that changes the flavor and the nutrition of everything you cook.

While he demonstrated technique, I explained what each ingredient can do for your heart and metabolism.

Barley gives beta-glucan, a soluble fiber that forms a soft gel in the gut and helps pull LDL cholesterol out of circulation. About half a cup of cooked barley gets you close to the 3 grams shown in studies to meaningfully lower LDL.

Porcini mushrooms add ergothioneine, a cellular antioxidant that protects DNA, along with beta-glucans that support immune function. Certain mushroom compounds can gently reduce aromatase activity, a pathway linked to lower lifetime estrogen exposure and reduced breast cancer risk. They don’t contain isoflavones; they work through entirely different biochemistry.

Kale played two roles tonight, in the risotto and in the salad. When you cut or chew kale, you activate myrosinase, an enzyme that converts its glucosinolates into isothiocyanates. These compounds reduce inflammation and support endothelial health, which is essential for keeping arteries responsive and resilient.

Red onions bring quercetin and anthocyanins, both of which improve blood vessel dilation, reduce oxidative stress, and help prevent LDL from becoming oxidized, the form that contributes to plaque.

Sunflower seeds offer vitamin E, plant sterols, and healthy unsaturated fats. Vitamin E protects LDL from oxidation, sterols reduce cholesterol absorption, and healthy fats improve lipid profiles and support flexible blood vessels.

And throughout the demo, Chef Martin showed how simple it is to build a flavorful homemade vegetable stock, one of the easiest ways to reduce sodium, deepen flavor, and add more phytonutrients to everyday cooking.

This is why I love cooking alongside him. The food tastes amazing, and every ingredient has a job inside the body: lowering inflammation, supporting arteries, calming oxidative stress, improving lipid handling, and gently tuning metabolic pathways.

What we made tonight wasn’t just dinner.It was a heart-healthy, metabolism-friendly blueprint you can use every day.

If you want to keep cooking this way — and understand why it works…

What science reveals about BDNF, mood, and movement

I’m Dr. Laurie Marbas, and in this episode I challenge the story we’ve been told about depression—that it’s just mindset, willpower, or a simple “chemical imbalance.” Yes, therapy and medication can be essential. But many of us are missing a quiet, biological piece of the puzzle: brain-derived neurotrophic factor (BDNF), the protein that helps your brain repair, rewire, and become resilient.

I break down what BDNF is (think: scaffolding for your neurons), why it’s so active in mood-related regions like the hippocampus, prefrontal cortex, and basal forebrain, and how low BDNF can leave you stuck—showing up as brain fog, low mood, and reduced stress tolerance. Here’s the hopeful part: you can nudge BDNF up with consistent, evidence-based actions that complement any therapy or medication plan.

In this episode, I:

* Explain how low BDNF contributes to depression—and why mindset alone isn’t the full answer.

* Share research showing depression can be linked with structural brain changes (like hippocampal shrinkage) and how BDNF supports repair.

* Walk through five non‑drug levers that raise BDNF: aerobic movement, mindfulness/breathing, CBT-style cognitive reframing, deep sleep, and real human connection.

* Reframe motivation: action drives biology first; the feelings follow.

Try my “Starting Line” this week (no perfection required):

* Move: Aim for ~150 minutes of moderate activity (walk, bike, swim).

* Breathe: Practice 4‑4‑6 breathing daily (inhale 4, hold 4, exhale 6).

* Sleep: Power down screens 1 hour before bed and keep a consistent lights‑out.

* Connect: Text someone today and schedule a 10‑minute check‑in.

* Reframe: Catch one unhelpful thought and replace it with a more balanced version.

I also created a simple, science‑backed worksheet—“Rebuild Your Brain: The BDNF Daily Builder”—to help you track these five signals over seven days and reflect on what’s working. Grab it from the show notes.

Listener note: Depression is complex—biological, psychological, social, and often genetic. This episode is educational and not a substitute for personalized care. If you’re struggling, please seek help from a licensed professional. Medication and therapy aren’t signs of failure; they’re tools—and you deserve a full toolkit.

In this deeply personal episode, Dr. Laurie Marbas shares how two “frozen” shoulders became the unlikely clue to a thyroid story decades in the making. After postpartum Hashimoto’s left her on levothyroxine, a later switch to a whole‑food, plant‑based diet unexpectedly made her medication too strong—pushing her into hyperthyroidism and triggering painful adhesive capsulitis in both shoulders. Adjusting the dose thawed her shoulders and stabilized her labs, and the experience reshaped how she thinks about thyroid care.

What you’ll learn

* Why the thyroid is your body’s “thermostat” and how hypo vs. hyper symptoms differ

* The surprising link between thyroid dysfunction and frozen shoulder (adhesive capsulitis)

* How major diet shifts can change your hormone needs—and what to watch for if you’re on levothyroxine

* The truth about soy and cruciferous veggies (broccoli, cauliflower) when iodine intake is adequate

* The lab panel beyond TSH: free T4, total T3, and thyroid antibodies—and how “optimal” can differ from “normal”

Resources

* Thyroid Reset Worksheet – labs to request, optimal ranges, a food list for thyroid support, and daily healing habits. (See show notes to download.)

TakeawayIf you’re exhausted, cold, foggy, losing hair, or battling stubborn joint pain, don’t ignore the whispers. Ask about your thyroid—and make sure you get the full picture, not just a TSH.
