Key Takeaway: 16/8 fasting restricts food consumption to an 8-hour window while fasting for 16 hours. Track your fasting circadian cycles with FastingTracker.net and log your feeding window macros on Calorie Tracker.
Mechanisms of 16/8 Fasting
By extending overnight fasting into the midday hours, plasma insulin levels drop to basal levels, activating hormone-sensitive lipase (HSL) and shifting substrate utilization from glucose oxidation to hepatic ketogenesis and fatty acid oxidation.
