A Systems-Based Educational Series

Cholesterol, Saturated Fat & the Cardiovascular Story

For decades, cholesterol and saturated fat have been at the center of one of the most influential conversations in modern health care.

The history of the lipid–heart hypothesis
The physiology of cholesterol
Vascular injury & inflammation
Modern lipid interpretation
Systems-based factors shaping cardiovascular risk today

The goal is not fear.
The goal is understanding.

A Note About Perspective

On certainty, perspective & the work of thinking for yourself.

This is a controversial subject, and I want to acknowledge that I do have a perspective here.

My lens is shaped by systems biology, clinical experience, historical pattern recognition, and a deep interest in how modern life has changed human physiology.

At the same time, I do not want you to simply adopt my views because I present them persuasively. I want you to investigate, think critically, and develop your own informed perspective.

I don't want you to borrow my certainty.
I want you to build your own discernment.

The Series

Eight lessons. One systems view.

Each lesson stands on its own and builds on the last. Watch in order, or move to the section most relevant to your current questions.

Lesson 0101 / 08

Essential Functions of Cholesterol

Explore the foundational role cholesterol plays throughout human physiology — far beyond its reputation as a cardiovascular villain.

  • Cell membranes
  • Hormone production
  • Vitamin D synthesis
  • Bile production
  • Brain & nervous system function
  • Repair physiology
Lesson 0202 / 08

Saturated Fat — Context Matters

A systems-based look at saturated fat, metabolic terrain, and why nutrients cannot be interpreted outside the environment they enter.

  • Saturated fat physiology
  • Metabolic context
  • Inflammation
  • Insulin resistance
  • The loss of nuance in modern nutrition
Lesson 0303 / 08

The Lipid-Heart Hypothesis

A historical exploration of how the cholesterol-heart narrative emerged, how it shaped modern dietary recommendations, and what may have been overlooked along the way.

  • Ancel Keys
  • The low-fat era
  • Processed food expansion
  • Systems-level factors in cardiovascular disease
Lesson 0404 / 08

What Actually Causes Heart Disease?

A systems-based explanation of vascular injury, endothelial dysfunction, inflammation, oxidation, and plaque formation.

  • Endothelial injury
  • Inflammation
  • Permeability
  • Oxidation
  • Immune activation

  • Metabolic & inflammatory patterns
  • Adaptive patterns such as LMHR
Lesson 05B06 / 08

Coronary Artery Calcium (CAC) Score

Understanding Structural Risk

An introduction to the Coronary Artery Calcium Score and how it can help assess actual plaque burden and cardiovascular risk.

  • Calcified plaque
  • Structural assessment
  • Risk stratification
  • Integration with systems-based lipid interpretation
Lesson 0607 / 08

How to Optimize Cholesterol Naturally

A systems-based approach to improving lipid health by improving the foundations of physiology.

  • Metabolic tone
  • Liver function
  • Inflammation
  • Movement, sleep, stress, nourishment
Lesson 0708 / 08

The Perfect Storm

How Modern Life Disrupted Human Physiology

A broader systems-level reflection on how modern life has collectively contributed to the rise of chronic disease across multiple systems of the body.

  • Processed food
  • Environmental toxicity
  • Chronic stress
  • Circadian disruption
  • Industrialization & lifestyle shifts
Closing

Systems That Heal

The goal of this series is not to create fear or certainty.

It is to create perspective, discernment, systems awareness, and a deeper understanding of human physiology.

When we understand the terrain,
we can ask better questions.
