Mechanistic Chronobiology Context
According to research summarized by Dr. Rhonda Patrick (@foundmyfitness), altering meal timing by 1 hour or more between workdays and weekends acts as a non-photic zeitgeber shift. While the central suprachiasmatic nucleus (SCN) remains locked to photic light cues, peripheral clock genes in liver, stomach, and adipose tissue align rapidly with food intake, causing organ-level phase divergence, inflammatory tone, and mood dysregulation.
