Episode notes
Diabetes As Glucose Overdose
- Berry reframes type 2 diabetes as chronic carbohydrate (glucose) overdose or toxicity.
- He argues lowering carbohydrate intake consistently and sufficiently reverses prediabetes and type 2 diabetes.
Target Fasting Insulin Under 10
- Aim for a fasting insulin under 10 µU/mL, ideally approaching 4–5, to indicate optimal metabolic health.
- Do not rely on LabCorp/Quest 'normal' ranges which accept much higher insulin values.
Ditch Carb-Heavy Breakfasts
- Avoid ‘healthy breakfast’ carbs like oats, bananas, honey, or fruit juice because they spike glucose and insulin.
- Use a CGM to see how so-called natural breakfasts raise blood sugar for hours, worsening metabolic health.
