The Health Pulse

What if your metabolism isn't broken—but simply following the rules it was designed to obey? In this episode of The Health Pulse, we unpack one of the most overlooked concepts in metabolism: the Randle Cycle, also known as the glucose-fatty acid cycle, and explain how it determines whether your cells burn glucose or fat at any given moment.

We explore why your body doesn't maximize both fuel sources simultaneously. Instead, it...

What if heart failure isn't simply a failing pump—but a failing energy system? In this episode of The Health Pulse, we explore the growing scientific view that heart failure is fundamentally a metabolic disease, where impaired cellular energy production may drive many of the structural and functional changes seen in the failing heart.

We begin by looking inside a single heart muscle cell, where mitochondria occupy a remarkable...

A "perfect" fasting glucose doesn't always mean your metabolism is healthy. In fact, it can hide one of the earliest signs of metabolic dysfunction. In this episode of The Health Pulse, we explore metabolic flexibility—your body's ability to seamlessly switch between burning carbohydrates, fat, and ketones for energy—and why losing this ability may explain fatigue, cravings, brain fog, and the dreaded afternoon energy c...

Free radicals have earned a reputation as the villains of aging and chronic disease—but the real story is far more fascinating. In this episode of The Health Pulse, we unpack the science of reactive oxygen species (ROS) and explain why your body deliberately produces these molecules every single day as an essential part of healthy cellular function.

We break down the major ROS molecules—including superoxide, hydrogen per...

What if the first line of defense against heart disease is something you've probably never heard of? In this episode of The Health Pulse, we explore the endothelial glycocalyx—a microscopic, gel-like layer that coats the inside of every healthy blood vessel and plays a critical role in protecting your cardiovascular system.

We explain how this delicate sugar-rich coating acts as a protective barrier between circulating blood a...

Heart attacks don’t begin when an artery suddenly becomes blocked. They often begin years or even decades earlier, with damage to one of the most important—and overlooked—organs in the body: the endothelium, the single layer of cells lining every blood vessel.

In this episode of The Health Pulse, we explore endothelial dysfunction, the earliest stage of cardiovascular disease, and explain why protecting this micros...

What if seemingly unrelated conditions like insulin resistance, brain fog, fatty liver, chronic fatigue, and heart failure all share the same underlying problem? In this episode of The Health Pulse, we explore mitochondrial dysfunction—a growing area of research that may help explain why so many chronic diseases are fundamentally disorders of cellular energy.

Using the analogy of a city powered by a shared electrical grid, we ...

Treating lupus by simply suppressing the immune system can sometimes feel like fighting a complex house fire with a single tool. In this episode of The Health Pulse, we explore a newer and fascinating concept known as immunometabolism—the science of how immune cells generate energy and how those metabolic pathways may influence inflammation in systemic lupus erythematosus (SLE).

We begin with the basics of lupus and why its un...

For decades, Alzheimer’s disease has been viewed primarily through the lens of amyloid plaques and tau tangles. But what if those hallmark features are only part of the story? In this episode of The Health Pulse, we explore a growing body of research suggesting that Alzheimer’s may also be a metabolic disease—a slow-developing energy crisis in the brain that begins years before memory loss becomes apparent.

We star...

Why do some people develop type 2 diabetes despite being lean, while others carry excess weight and maintain relatively normal blood sugar? In this episode of The Health Pulse, we explore the Low Personal Fat Threshold Theory, a compelling framework that challenges the conventional belief that obesity alone drives metabolic disease.

Using a simple but powerful analogy, we explain why judging metabolic health by appearance is like ju...

What if ALS isn't just a disease of dying motor neurons—but also a disease of impaired cellular energy? In this episode of The Health Pulse, we explore a fascinating metabolic perspective on amyotrophic lateral sclerosis (ALS) and why researchers are increasingly investigating ketogenic metabolic therapy as a potential supportive strategy.

We begin by examining the enormous energy demands of motor neurons. These specialized ce...

A diagnosis of severe Crohn’s disease often comes with a familiar message: manage the condition, suppress inflammation, and prepare for a lifetime of treatment. But what happens when a case report challenges that narrative?

In this episode of The Health Pulse, we examine a fascinating 2016 case report involving a 14-year-old patient with active Crohn’s disease who experienced dramatic improvements after following a Paleo...

What if some of the foods we consider “healthy” are contributing to gut dysfunction in certain people? In this episode of The Health Pulse, we take a deep dive into the Paleolithic Ketogenic Diet (PKD)—a highly restrictive therapeutic approach centered on red meat, animal fat, and organ meats while excluding dairy, grains, legumes, and nearly all plant foods.

We explore the theory driving PKD: that intestinal perme...

A normal glucose result can create a false sense of security. In this episode of The Health Pulse, we explore hyperinsulinemia—chronically elevated insulin—and why it may be the real metabolic warning sign long before prediabetes or type 2 diabetes officially appear.

We break down the body’s compensation phase, where the pancreas produces more and more insulin to keep blood sugar looking “normal,” somet...

Just a few nights of poor sleep can dramatically change the way your body handles food, stress, and fat storage. In this episode of The Health Pulse, we break down the hidden metabolic consequences of sleep deprivation—and why five hours of sleep can reshape your glucose response by breakfast.

We explain how fragmented sleep rapidly triggers acute insulin resistance, leaving glucose circulating longer while the pancreas compen...

A normal 8 a.m. cortisol test can feel definitive—until your body keeps telling a completely different story. In this episode of The Health Pulse, we unpack the frustrating disconnect between “normal” cortisol labs and symptoms like central weight gain, thinning limbs, muscle weakness, fatigue, and brain fog that resemble Cushing’s syndrome.

We explain why a single morning cortisol draw is often just a snapsh...

Cancer is usually framed as a story of bad genes and random mutations—but what if the body’s internal metabolic environment plays a much larger role than we’ve been taught? In this episode of The Health Pulse, we explore the emerging view of cancer as a metabolic disease, where insulin signaling, glucose handling, inflammation, and mitochondrial dysfunction may influence how tumors grow, survive, and evade the imm...

Your glucose can rise before you eat a single bite—and it’s not a glitch. In this episode of The Health Pulse, we uncover the physiology behind fasting blood sugar and explain why your liver and hormones may be pushing glucose higher while you sleep.

We walk through how the liver runs an overnight fuel program to keep the brain and organs supplied with energy, then zoom into the dawn phenomenon—the early morning su...

That “perfectly normal” fasting glucose can be one of the most misleading signals in metabolic health. In this episode of The Health Pulse, we unpack why symptoms like shakiness, brain fog, and afternoon crashes often have nothing to do with resting glucose—and everything to do with what happens after you eat.

We break down the mechanics of reactive hypoglycemia, explaining how blood sugar isn’t static but dy...
