Understanding the Signaling and State Changes in Fasting

Short answer: 4-6 hours after a meal the small intestine is emptied and the insulin-to-glucagon ratio declines; 25 hours after, hepatic glycogen is emptied; 5 days later the brain is adapted to ketones and gluconeogenesis reaches its minimal level. Moving from one to the other cannot occur with a small piece of signaling like the bite of an apple. It requires the preponderance of signaling.
