Treadmill Talks - Signal Over Duration 18 hr fast 6 hr controlled eating window 36 hr fast Why? Because insulin and liver glycogen are the gatekeepers of metabolic signaling. 18 hours lowers insulin and begins liver glycogen depletion. The 6 hour window keeps food simple and stress low. The 36 hour fast drives deep fat burning once insulin is low and liver glycogen is drained. Most people fast for time. I fast for signal. If you don’t control insulin and liver glycogen, you don’t control metabolic signaling. Structured rhythm. Not restriction.
