Circadian-aligned eating
Protocols · Fasting
Tier B
What this is
Late eating impairs glucose tolerance even when macros are matched. Mechanistic data stronger than outcome trials. Shift workers show elevated disease risk partly due to circadian-eating mismatch.
Mechanism
Feeding synchronizes peripheral clocks (liver, adipose, gut) with suprachiasmatic nucleus; glucose/lipid metabolism more efficient during active phase; melatonin opposes insulin
Dose & route
Finish eating 2-3 hours before sleep; largest meals earlier in day; no snacking at night
