Episode description
- Type 2 diabetes directly damages your heart's ability to make energy, leaving you more vulnerable to fatigue, swelling, and heart failure
- Human heart tissue studies show that mitochondria — the power plants of your cells — lose key components in diabetic hearts, forcing the heart to beat with less fuel
- Fat and sugar metabolism both become inefficient, and backup fuels fail to provide support, leaving your heart stranded without reliable energy sources
- Structural changes inside the heart, including scar-like collagen buildup and weaker calcium-handling proteins, make each heartbeat less coordinated and less powerful
- You can take action by cutting linoleic acid (LA) from your diet, choosing the right carbohydrates, limiting environmental toxins, using sunlight strategically, and tracking your insulin resistance with HOMA-IR to protect your heart's energy systems
