16:8 Protocol
The Balanced Standard
16:8 involves fasting for 16 consecutive hours followed by an 8-hour eating window. Typically accomplished by finishing dinner in the early evening and delaying breakfast until midday, it fits easily into normal working and social schedules.

Nutrients from the preceding meal are digested and absorbed, during which circulating glucose and insulin naturally respond.
As nutrient absorption completes, insulin levels generally trend toward baseline, and stored glycogen is gradually utilized.
As liver glycogen gradually depletes, the body typically increases reliance on fatty acids for resting energy needs.
Extended nutrient pauses are associated in scientific models with cellular maintenance signals (including AMPK and mTOR pathways).
How the 16:8 Protocol Works in Practice
Under the 16:8 protocol, each 24-hour cycle is segmented into a continuous 16-hour fasting period followed by an 8-hour feeding window. Fasting begins the moment your final evening meal concludes.
