New to fructose metabolism? You're in the right place.

Most of what you'll read on this blog is grounded in recent science, and a lot of it may be new to you. The best place to begin is our Fructose Metabolism Master Guide — a complete walkthrough of how fructose works in the body, why it's central to metabolic health, and what the latest research means for you. From there, our posts dig into the specifics. And if you'd rather talk it through, our chat is always open.

Health should give you more life, not become your life. Chris Mearns shares a practical framework for eating, training, sleeping and supporting metabolic health without turning wellness into another prison.

High-Fructose Corn Syrup vs. Sugar: What's Actually Worse for Metabolic Health?

High-Fructose Corn Syrup vs. Sugar: What's Actually Worse for Metabolic Health?

High-fructose corn syrup and regular sugar are not the same thing metabolically, even though both contain fructose. HFCS delivers fructose in a free, unbound form that floods the liver faster, triggering fat storage and uric acid production at a higher rate than sucrose. That said, regular sugar is not innocent either. Both cause measurable metabolic damage at the doses most Americans consume daily.

Fructose Is Not Just Sugar: A Signalling Molecule Regulating Cellular Energy and Metabolic Disease

Fructose Is Not Just Sugar: A Signalling Molecule Regulating Cellular Energy and Metabolic Disease

For decades, fructose and glucose have been grouped together as simple sugars, often treated as metabolically interchangeable. That assumption works at the level of chemistry, but it breaks down in biology.

Multiple Sclerosis Recovery: Is a

Multiple Sclerosis Recovery: Is a "Power Outage" Causing Your MS Fatigue?

MS fatigue can feel like your body’s battery is stuck at 5%, no matter what you do. Beyond immune attacks, research shows a hidden energy crisis in cells—mitochondria get trapped in “Eco-Mode,” diverting energy from nerve repair. A metabolic “leak” called the KHK pathway drains essential energy parts, spreading fatigue across the nervous system. Addressing this leak and supporting mitochondrial repair, with tools like Luteolin, helps restore cellular energy, allowing nerves to recover and MS fatigue to improve.

Perimenopause can disrupt metabolism, and fructose may make it worse. This blog uncovers how fructose affects hormonal balance, weight gain, and energy—and how to support your body naturally.

Luteolin: The Anti-Sugar Nutrient You’ve Never Heard Of (But Need to Know About)

Luteolin: The Anti-Sugar Nutrient You’ve Never Heard Of (But Need to Know About)

Luteolin is a rare plant flavonoid shown to naturally quiet the fructose pathway—the same metabolic switch targeted by pharmaceutical fructokinase inhibitors. By protecting cellular energy and lowering uric acid and inflammation, it helps restore the stable, high-efficiency metabolism that modern diets have lost.

Huntington’s Disease Breakthrough: Gene Therapy AMT-130 and the Energy Failure Model

Huntington’s Disease Breakthrough: Gene Therapy AMT-130 and the Energy Failure Model

A new gene therapy has slowed Huntington’s disease progression for the first time — a historic breakthrough. Seen through the energy failure model, it also highlights how metabolic stress like fructose stacks on top of genetic insults, and why research on luteolin is showing promise across multiple neurodegenerative conditions.

The Fructose–Insulin Connection: What Doctors Aren’t Telling You About Weight Loss Resistance

The Fructose–Insulin Connection: What Doctors Aren’t Telling You About Weight Loss Resistance

Doctors often blame carbs in general, but that's only part of the story. To really answer what causes insulin resistance, we need to look at fructose. If the engine is the problem, pressing harder on the gas pedal won't help. Instead, the solution is to improve how the cell handles fuel and gradually rebuild insulin sensitivity.
