Episode notes
Insulin Resistance Lets The Liver Overproduce Glucose
- Insulin is the off switch for hepatic glucose production and insulin resistance disables that switch.
- Dr. Eric Berg DC describes long-term high insulin exposure causes cells to ignore insulin, so the liver keeps making excessive sugar.
High Insulin Can Mask Blood Sugar Problems For Years
- High insulin can mask high blood glucose for years by clearing sugar from the blood until insulin fails.
- Dr. Eric Berg DC notes you can eat lots of carbs for 10–20 years with high insulin and normal glucose until insulin deficiency emerges.
Stress And Cortisol Can Raise Blood Sugar Independently
- Excess stress and cortisol drive blood sugar up by stimulating glucose release.
- Dr. Eric Berg DC highlights medications like prednisone or chronic stress raise cortisol and can push someone into diabetes by releasing large amounts of sugar.
