What is the Origin of Fasting Strategies?

The term is a compound of 'fasting,' derived from the Old English fæstan (to abstain from food), and 'strategies,' referring to a plan of action or systematic approach. It describes the intentional, timed application of nutrient deprivation for therapeutic or health optimization purposes.

What is the Mechanism of Fasting Strategies?

Fasting initiates a critical metabolic switch from primary glucose utilization to the efficient use of fat and ketone bodies for energy, a process that promotes cellular repair and recycling processes such as autophagy. Hormonally, fasting significantly lowers circulating insulin levels and elevates glucagon and growth hormone, leading to increased lipolysis and profoundly improved systemic insulin sensitivity. These beneficial hormonal shifts are key drivers of the clinical and longevity benefits associated with these time-restricted eating protocols.
