Triglycerides & Insulin Resistance Explained: The Hidden Engine Behind Heart Disease

Most people focus only on LDL cholesterol — but high triglycerides may be the most underestimated cardiovascular risk factor in modern medicine. And the reason so many people have high triglycerides comes down to one thing: insulin resistance. In this deep-dive video we explain exactly what triglycerides are, how insulin resistance drives them up, and why they damage arteries through mechanisms your standard cholesterol panel completely misses. KEY TOPICS: What triglycerides actually are and how they circulate in your blood Triglyceride levels: what the numbers mean (less than 150 / 150-199 / 200-499 / 500+) How triglyceride-rich remnant particles directly cause plaque — the Copenhagen City Heart Study (5x higher heart attack risk in the highest quintile) The atherogenic lipid triad: high TG + low HDL + small dense LDL INSULIN RESISTANCE EXPLAINED COMPLETELY: What insulin resistance is and how it silently develops for years Exactly how insulin resistance drives triglycerides up — 4 mechanisms: 1. Liver VLDL overproduction (suppression failure) 2. Impaired LPL-mediated clearance 3. Excess free fatty acid release from fat tissue 4. Fructose → de novo lipogenesis (the sugar-fat connection) How high triglycerides then worsen insulin resistance — the vicious cycle The triglyceride-to-HDL ratio: your free insulin resistance screen Metabolic syndrome — 35% of American adults, 2x cardiovascular risk Non-alcoholic fatty liver disease (MASLD) — 64% higher CV risk (Journal of Hepatology 2023) ⚠️ This video is for educational purposes only and does not constitute medical advice.
