Gastric and duodenal motility, food intake and hunger measured in man during a 24-hr period


The relationship between gastric and duodenal motility, reports of hunger, and spontaneous food intake were studied over a 24-hr period in 3 healthy young women. Hunger began to increase soon after the end of a meal and continued to increase until it fell abruptly at the time of the next meal, when the process began again. Neither gastric nor duodenal motility had any influence upon food intake. Although hunger usually increased during periods of gastric and duodenal motility, it also increased in the absence of such motility, and on one occasion, did not increase during nearly 2 hr of gastric motility. It was concluded that neither gastric nor duodenal motility influenced either food intake or reports of hunger.
