Liquid meal attenuates meal anticipation in rat adrenocortical activity.
Effects of dietary consistency were examined on the development and persistence of meal anticipation in adrenocortical activity in rats under restricted daily feeding (RF), in which food supply was restricted to a fixed time of day. Restricted daily solid meal produced the anticipatory hormone peak in 8 days, whereas restricted daily liquid meal produced the peak in 12 days. The developed hormone peak was less prominent by liquid meal than by solid. The anticipatory corticosterone peak developed by solid meal persisted throughout the period examined (3 weeks) after the termination of RF, whereas the peak developed by liquid meal disappeared after the first week. It is concluded that liquid meal attenuates the meal anticipation in the adrenocortical activity in rats under RF.
