Therapeutic intermittent fasting: The hormonal basis of insulin regulation

Cyclic suppression of basal and postprandial insulin levels through structured 16:8 daily time-restricted eating or alternate-day 24-hour fasts, allowing depleted liver glycogen and opening cellular gates for macro-autophagy.
Primary Citation: The Obesity Code: Unlocking the Secrets of Weight Loss (2016).
Verified Public Record: "Obesity is a hormonal imbalance of hyperinsulinemia, not an issue of caloric math. You cannot access and burn endogenous body fat when circulating insulin levels are elevated, and intermittent fasting is the most potent natural way to drop insulin." — The Obesity Code (Chapter 16: Fasting: The Ancient Secret, p. 211 (2016))

Drinking green tea during the fasting window stimulates autophagy while keeping basal insulin levels completely suppressed.
