What is the Origin of Fasted Sleep Protocol?

This term is a modern construct within the wellness and intermittent fasting movements, drawing on principles from endocrinology and chrononutrition. It recognizes the critical metabolic distinction between the fed and fasted states, particularly concerning insulin and growth hormone. The protocol formalizes the ancestral pattern of overnight fasting.

What is the Mechanism of Fasted Sleep Protocol?

By ensuring a low plasma glucose and insulin state before and during sleep, the protocol removes the inhibitory signal of insulin on growth hormone (GH) release. The resulting low energy availability stimulates the pituitary to release higher-amplitude GH pulses, which promote lipolysis and protein synthesis. Furthermore, the absence of late-night feeding allows the digestive system to rest, diverting energy toward cellular housekeeping and repair pathways.

Fasted Sleep Protocol

Meaning

A lifestyle and nutritional strategy that involves maintaining a period of caloric abstinence throughout the nocturnal sleep phase and for a defined duration leading up to bedtime. The primary clinical goal is to maximize the body’s reliance on fat oxidation during sleep and to optimize the hormonal environment for growth hormone secretion and cellular repair. This protocol aims to leverage the fasting state to enhance metabolic flexibility and restorative sleep processes.
