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.
