Episode notes
Fatty Liver Is A Metabolic Epidemic
- Fatty liver disease is now the most common liver disorder and often stems from metabolic dysfunction rather than alcohol.
- Dr. Joseph Mercola links its rise to obesity, type 2 diabetes, and insulin resistance acting together to overload the liver.
Insulin Resistance Turns The Liver Into A Dumping Ground
- Insulin resistance causes high insulin and blood energy with cells that no longer take up fuel, forcing the liver to store the excess as fat.
- Mercola compares the liver to a warehouse where supply keeps arriving but the workers stop responding to the insulin 'doorbell'.
Silence Makes Fatty Liver Dangerous
- Fatty liver often progresses silently for years because the liver has few nerve endings and rarely causes early symptoms.
- Mercola warns feeling well is a poor indicator of liver health and damage can compound unnoticed for decades.
