Deprivation and time of testing as determinants of food intake.

Abstract
The effects of length of deprivation and the time of day at which food is restored on the course of subsequent food intake were studied in rats. Increasing the deprivation period led most prominently to an increase in the size of the first meal; the magnitude of this effect was influenced by the time of restoration of food in a manner best explained by considering the momentary strength of all drivers.
