Episode: Office Hours: Cholesterol and Heart Disease — What I’ve Changed My Mind About
Host: Dr. Mark Hyman
Date: February 2, 2026

Episode Overview

In this Office Hours episode, Dr. Mark Hyman offers a candid, up-to-date look at what the latest science reveals about cholesterol, heart disease, and the root causes behind America's leading killer. Reflecting on how his own medical views have evolved, Dr. Hyman challenges conventional thinking about cholesterol, statins, and dietary fat, highlighting why metabolic dysfunction and inflammation—not cholesterol alone—are the primary drivers of heart disease. Throughout, he emphasizes the power individuals have to understand and optimize their own heart health, detailing the lab markers and lifestyle shifts that matter most.

Key Discussion Points & Insights

1. Rethinking Cholesterol and Heart Disease (01:00–06:30)

• Dr. Hyman explains how traditional medical training taught him that:
  • High cholesterol, especially high LDL, directly causes heart attacks.
  • The main goals were to "avoid fat, lower cholesterol, and take a statin" (02:40).
• He recognizes that new research and real-world patient outcomes challenge this simplistic model.
• Notable issue: Many people with heart attacks have "normal" LDL cholesterol levels.
  • Quote: “If cholesterol were truly the main cause of heart disease, then why do half the people who have heart attacks have normal LDL levels?” (04:48)

Transition Quote

“We have to look at the things that we hold onto, like these sacred idols. And we have to let them go if the science doesn’t prove that they’re true anymore.” — Dr. Mark Hyman (01:35)

2. The Limits of Traditional Cholesterol Testing (06:30–11:00)

• Standard cholesterol panels (total cholesterol, LDL weight) are poor predictors of heart disease.
  • Only a small fraction (<1%) of labs actually test for cholesterol quality, size, and number of particles.
• Tests that matter but are rarely run include apolipoprotein B (APOB) and lipoprotein(a) [“LP little a”].
• Inflammation, not just LDL, is a crucial driver.
  • Key marker: high-sensitivity C-reactive protein (hs-CRP).
• Paul Ridker’s research (Harvard) showed high inflammation → higher risk, even with normal cholesterol.

Memorable Quote

“The risk really comes from something that's not being tested by almost every doctor in the country… less than 1% of their tests do this.” — Dr. Mark Hyman (09:30)

3. Metabolic Dysfunction: The Real Root of Heart Disease (11:00–16:30)

• Metabolic dysfunction—insulin resistance, pre-diabetes, belly fat—is the underlying cause for most heart disease.
• Sugar and refined starches, not fat, drive this epidemic.
• Key insight from a national heart attack study: 75% of patients had “normal” LDL, but most had:
  • High triglycerides and/or low HDL cholesterol—simple proxies for insulin resistance.
• Quote: “The real take home here is that here’s the headline: It’s sugar, not fat, that’s causing you to die of heart attacks.” (13:48)

4. The Most Important Tests for Heart Disease Risk (16:30–21:30)

Tests Dr. Hyman recommends:

• APOB: The most reliable marker, now finally recognized as causal for heart disease.
• Lipoprotein(a) [LP(a)]: Genetic marker—elevated in up to 20% of people.
• hs-CRP: Marker of inflammation, often more predictive than LDL.
• Fasting Insulin & Insulin Resistance Scores: Rarely checked but vital for understanding metabolic health.
• Triglyceride-to-HDL Ratio: Gives a quick snapshot of insulin resistance—should be close to 1:1.

Practical Anecdote

Dr. Hyman describes how his own weight briefly increased in Italy after eating more starches and sugar, underscoring how quickly dietary choices impact metabolic health (18:28).

5. Inflammation and Diet: The True Culprits (21:30–25:00)

• High intake of sugar and refined carbohydrates causes inflammation, which damages blood vessel linings, allowing cholesterol to deposit.
• “Angry” visceral belly fat is metabolically active and highly inflammatory.
• Most Americans (93.2%) have some degree of metabolic dysfunction, which can occur even in people of normal weight (“skinny fat”/TOFI).

Quotes & Simple Tests

“When you have inflammation, guess what happens? You oxidize the LDL… that rancid fat is dangerous.” (22:56)

“You don’t even need a tape measure… jump in front of the mirror, up and down. If your stomach jiggles, you probably have this problem.” (25:00)

6. Practical Steps: What to Do Next (25:00–33:30)

Testing

• Ask for: APOB, LP(a), hs-CRP, fasting insulin, triglyceride:HDL ratio, lipoprotein fractionation, and a coronary calcium score imaging (to assess actual plaque).
• Track your lab trends over time, not just a single value.

Diet and Lifestyle Interventions

• Eliminate most sugar and refined starch.
• Focus on whole, low-glycemic, anti-inflammatory foods.
• Prioritize exercise, especially strength training and daily movement.
• Manage stress; sleep well.

Supplements (with Physician Guidance)

• High-quality omega-3 fish oil (triglyceride lowering, anti-inflammatory).
• Multivitamin/mineral supplement (covering folate, zinc, magnesium, etc.).
• CoQ10, magnesium, fiber, and plant sterols.

Dr. Hyman’s Rule of Thumb

“Supplements are not one size fits all. They’re not a replacement. They’re called supplements for a reason.” (31:42)

7. The New Paradigm: Metabolic and Inflammatory Health Over Cholesterol (33:30–36:10)

• For most, heart disease is a “metabolic and inflammatory disease first.”
• Cholesterol is often just a bystander or surrogate; genetics play a role for a minority.
• Focus on labs and lifestyle changes that impact true drivers (insulin resistance, inflammation).

Final Takeaway

“By understanding your numbers, by knowing what’s going on with your biology, you have the power to change your heart health right now… You’re not really at the mercy of your genetics or your numbers.” (35:32)

Memorable Quotes

Action Steps & Closing Wisdom

• Test, don’t guess: Get the right labs (APOB, LP(a), hs-CRP, fasting insulin, etc.).
• Eat for lower inflammation and improved insulin sensitivity: Ditch sugary and processed foods.
• Move, manage stress, and sleep: These are as critical as medication for most.
• Track trends: Yearly or semi-annual labs give real insight.
• Remember: Heart health change is possible—most heart disease is driven by lifestyle and metabolic health, not simply cholesterol.

“Every choice you make can move you closer to healing and vitality… You have far more power and agency than you realize.” — Dr. Mark Hyman (36:10)
