What if improving your brain function starts with fixing your metabolism?

In this episode, we explore why the ketogenic diet can be powerful for cognitive health — not necessarily as a lifelong approach, but as a tool to help the brain function more efficiently and restore metabolic balance.

Many people have never experienced ketosis.
And when they do, the shift in mental clarity can be eye-opening.

Why? Because the brain responds strongly to blood sugar stability and metabolic flexibility, something many people today struggle with.

We also discuss:

• why metabolic damage is driving cognitive decline
• how metabolic flexibility supports long-term brain health
• how glutamine may help regulate blood sugar, support gut healing, and calm the nervous system
• why supporting metabolism is foundational for cognition

Brain health isn’t just neurological, it’s metabolic.

Burnout rarely comes from not trying hard enough.

It comes from forcing approaches that don’t match your physiology and blaming yourself when they don’t work.

Precision is not restrictive. It’s protective.

Every single cell in your body depends on amino acids.

They’re not just about muscle or protein intake — they’re the building blocks for your brain chemistry, hormones, digestion, skin, and cellular repair.

But today, many people are quietly depleted.

Modern diets, poor digestion, chronic stress, and hormone imbalances can reduce the amino acids your body needs to function well. And when those levels drop, the effects can show up as:

• anxiety or low mood
• cognitive decline
• poor gut repair
• inflammation and “leaky gut”
• low energy and resilience

I recently sat down with Laurie Hammer, and she shared how restoring amino acid balance can help rebuild brain chemistry, support gut healing, and strengthen the body’s natural repair systems.

When we nourish the body at this foundational level, everything works better.

Many people today are living in a constant state of “overdrive.”

Feeling anxious.
Tense.
Wired but exhausted.
Unable to sleep.
Overwhelmed by everything.

This isn’t just stress.
It can be brain chemistry.

In my latest episode with Laurie Hammer, we explore how targeted amino acids help rebuild the pathways that support calm, focus, and emotional balance.

These compounds act as building blocks for neurotransmitters that regulate mood, sleep, and resilience — helping the nervous system settle, not just in the brain, but throughout the entire body.

When we support brain chemistry at the root, the body often shifts from stress to stability in a gentle, measurable way.

One of the most common things I hear is:
“I followed the plan exactly… and I still felt worse.”

That experience doesn’t mean you failed.
It usually means the plan wasn’t designed for your brain.

Genetics, stress load, metabolism, and life context all change how someone responds, even to “good” advice.

The goal isn’t stricter discipline. It’s a better fit.

If this took some weight off your shoulders, save it.

Hormones influence brain growth, repair, and resilience, but only when used thoughtfully.

When dosing ignores physiology, we risk missing their true potential.

My conversation with Dr. Felice Gersh explores why hormone therapy needs to be smarter, more precise, and aligned with how the brain actually functions over time.

It’s easy to turn symptoms into stories.

“I’m just bad at focusing.”
“I guess this is normal aging.”
“I should be handling this better.”

But many of the things people feel frustrated or embarrassed by are actually signals, not flaws.

Signals can be listened to.
And signals can be worked with.

This is a conversation we need to keep having.

One of the great gaps in modern medicine is that food (arguably our most powerful tool for healing) has been treated as secondary, even optional.

Yet what we eat profoundly influences inflammation, metabolism, gene expression, and long-term brain health.

Dr. Mark Hyman, a good friend of mineand trusted colleague, lays this out with clarity in Food Fix: Uncensored. What we’re seeing isn’t a failure of patients or physicians, it’s a system built to manage disease rather than prevent it.

If we want to change the trajectory of chronic illness and cognitive decline, prevention has to become the foundation of care, not an afterthought.

And that work begins on the plate.

Menopause deserves better than being framed as a disability.

The increased attention on menopause has opened important conversations about how hormone loss affects the brain, metabolism, and long-term health (and that’s a good thing)

But the goal isn’t accommodations like restrooms and showers.
The goal is proper treatment.

When menopause is understood as a physiological transition that deserves thoughtful, evidence-based care, not something women simply have to endure, we protect cognition, vitality, and longevity without limiting women’s potential or progress.

This book matters deeply to me.

Dr. Mark Hyman is not only a leader in functional medicine, but he’s also a dear friend whose work I respect immensely.

In "Food Fix: Uncensored," he speaks clearly and courageously about something I see every day in my clinic: our food system is shaping our health far more than we’ve been taught to acknowledge.

This isn’t about willpower or personal failure. It’s about a system that drives inflammation, metabolic dysfunction, and long-term brain vulnerability, often starting in childhood.

What I appreciate most about this book is that it doesn’t just diagnose the problem. It offers a roadmap for change—one rooted in prevention, nourishment, and restoring health at its foundation.

If you care about metabolic health, cognitive resilience, and the future we’re creating for the next generation, this is an important read.

Many people try to improve their memory by training their memory.

But memory depends on fuel.

When the brain doesn’t get reliable energy, clarity fades first... not because you’re “losing it,” but because neurons are underpowered.

This is why supporting blood sugar, insulin sensitivity, and metabolic health often improves focus and mood before memory changes.

Sometimes the fastest progress comes from working indirectly.

What if your dentist asked about your sleep… your diet… and your brain health?

That’s the direction whole health dentistry is heading.

Oral health doesn’t exist in isolation. The mouth is the gateway to the body, influencing inflammation, oxygen delivery, and long-term cognitive health.

My latest episode with Dr. Erela Katz Rappaport explores why dentistry may play a much bigger role in brain health than we’ve been taught to believe.
