Temporal Bounds of Post-ingestive Glucose induced Satiety in Man

Abstract

MOST studies of the short term effects of the intake or administration of nutrients on hunger in man have been based on verbal reports. Whether these purport to describe the intensity of the desire for food—appetite itself—or the various sensations the subject habitually experiences when wanting food, the validity of such reports ultimately rests on what the subject wishes or does not wish to eat. We¹, in common with some other workers², have found it quite practicable to observe meaningful variations in the spontaneous size of meals taken when the subject is introduced to the experimental foods with little or no manipulation of his feeding behaviour before the experimental session. We wish to report here a study of the satiating effects which glucose produces after it has passed the mouth. It is intended to complement our previous study of the satiating effects of protein¹.
