Food reward without a timing component does not alter the timing of activity under positive energy balance

Highlights • Timed daytime feeding induces food anticipatory activity but the regulatory mechanisms are unknown. • Daytime chocolate feeding induces diurnality in mice, but working for chocolate without timing constraints does not. • Timed feeding and energetic challenges are both sufficient to indu...

Description
Summary:	Highlights • Timed daytime feeding induces food anticipatory activity but the regulatory mechanisms are unknown. • Daytime chocolate feeding induces diurnality in mice, but working for chocolate without timing constraints does not. • Timed feeding and energetic challenges are both sufficient to induce diurnality in mice. • Food anticipatory activity likely results from additive effects of distinct reward and metabolism-regulating pathways.
