Insulin isn’t about sugar.
It’s about abundance.

Part IV of The Metabolic Web is live:
Insulin - The Governor of Abundance.

The Metabolic Web has taken us from chemistry to power.

Mrs. Alvarez has six doctors… and still no one who sees the whole picture.
Fragmented care is one of the quiet harms in modern medicine — and we almost never name it.

Here’s her story.

A website dedicated to health and nutrition, focusing primarily on healthy lifestyle and prevention of disease. Written by an experienced doctor and cardiologist.

New article today: The Statin Empire — And What Now?

Statins saved lives, but they also reshaped prevention around a single surrogate. Now, the cracks are visible, the drift is undeniable, and new therapies are on the horizon.
This is a story about breakthroughs, blind spots, and the next frontier in heart disease.

From a Tokyo laboratory to modern cardiology wards, this essay traces the rise of the statin empire—and the lessons it left for the future of prevention.

Yesterday I published Episode 2 of The Metabolic Web: Engines of Life.
It traces the moment mitochondria entered the story — the quiet merger that let cells harness oxygen, build complexity, and inherit a lifelong burden of repair.
A short read with long echoes.

How a single merger reshaped the fate of every living thing.

The Spark is out.
It’s the opening chapter of The Metabolic Web, my new series on how energy shapes life — and how its failures shape disease.
If you want the deeper story behind metabolism and modern health, start here.

Where life begins, and how energy becomes order

If you know a man around fifty who looks a little more tense than he used to — a little more tired, a little more inward — he’s not alone.

Many men feel “off” at midlife without knowing why.
They don’t complain.
They don’t talk about it.
But the body always tells a quiet story.

This new piece tries to describe that story.

Many men feel “off” at fifty without clear symptoms. This article explains the hidden physiology, stress, and disconnection that quietly shape midlife heart health.

Inside the Artery - The 13 Steps of Atherosclerosis is now complete. Thirteen steps, from the first endothelial whisper to the final moment the blood turns against itself.

If you’ve been following the journey, this is the full map. If not, this is the perfect time to start.

All 13 chapters are now published — and linked here in one place.

A new series on how heart disease really happens — and how to stop it before it starts

We think we know the story of JFK and Marilyn Monroe.
But the truth is quieter, stranger, and far more revealing than the myth that survived them.

Episode 11 of The Heart of Power is out now:
JFK, Marilyn, and the Myth We Never Let Go.

A gripping narrative of JFK and Marilyn Monroe—two icons held up by illusion, medicine, and pressure. A story of fragility behind American glamour.

In 2012, I wrote about low-carb diets and heart disease. It felt like rebellion.
Thirteen years later, the data — and my perspective — have changed.
Here’s what time, patients, and a little humility have taught me.

Exploring how carbohydrate restriction reshaped our understanding of heart disease, metabolism, and the quiet revolution in modern cardiology.

For the patient, there is no such thing as a “routine” procedure.

Behind every familiar rhythm in medicine lies a moment of surrender — and a trust we should never take for granted.

My new essay explores what happens on both sides of the drape.

A cardiologist reflects on what “routine” really means in medicine—and how trust and vulnerability define every procedure, from cath lab to endoscopy suite.

What happens when a U.S. president with malignant narcissism is “treated”?
This story imagines the experiment no one should ever attempt — a psychological thriller about power, empathy, and the danger of curing what keeps evil contained.

You can’t survive medicine by feeling everything — but you can’t honor it by feeling nothing.

This essay is for everyone who carries the weight of patient care — doctors, nurses, therapists, anyone who’s ever stayed past their shift because they still cared.

A reflection on the quiet cost of compassion — and how doctors learn to stay human in a profession that tests the heart as much as the mind.
