The “other” circadian system: food as a Zeitgeber

Stephan, F.K.·2002·Journal of Biological Rhythms

Abstract

It is not surprising that limiting food access to a particular time of day has profound effects on the behavior and physiology of animals. It has been clear for some time that pre-meal behavioral activation, a rise in core temperature, elevated serum corticosterone, and an increase in duodenal disaccharidases are under circadian control and that the observed circadian properties are not abolished by lesions of the suprachiasmatic nucleus (SCN), but the search for the locus of a separate food-entrainable oscillator (FEO) has not been successful. The cloning of circadian clock genes and the discovery that these genes are expressed in many central nervous system structures outside the SCN and in peripheral tissues have led to new strategies for investigating potential loci of an FEO. Recent findings concerning the entrainment of clock gene expression in the central nervous system and in peripheral tissues by periodic food access are presented, and the implications of these findings for a better understanding of a circadian system that entrains to meals, rather than to light, are discussed.

  • Food can regulate various peripheral body clocks and metabolic rhythms and is often referred to as a zeitgeber.

    “Food is often referred to as a zeitgeber (14) because of its ability to regulate various peripheral body clocks and metabolic rhythms (2, 15, 16).”
  • Food intake and eating patterns exhibit diurnal rhythms.

    “Food intake and eating patterns likewise exhibit diurnal rhythms (14, 17)”
  • Restriction of food availability to a short time window causes behavioral and physiologic changes, including food anticipatory activity.

    “It has been known for many decades that restriction of food availability to a short time window will cause the manifestation of behavioral and physiologic changes, including food anticipatory activity.”
  • Animals shift their activity rhythms and sleep/wake cycle in response to restricted food availability at a certain time of day.

    “Animals also shift their activity rhythms and sleep/wake cycle in response to restricted food availability at a certain time of day (Stephan, 2002).”

  • Entrainment to food or other non-photic stimuli is controlled by SCN-independent pacemakers located in various regions of the brain and other organs.

    “This entrainment to food, or other non-photic stimuli, is controlled by SCN-independent pacemakers located in various regions of the brain and other organs (Stokkan et al., 2001; Stephan, 2002; Mieda et al., 2006).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
