BACKGROUND AND AIMS The mechanism of intraduodenal fat induced inhibition of food intake is still unclear. Therefore, we tested the ability of duodenal fatty acids to suppress food intake at a lunchtime meal; in addition, we were interested to test if these effects were mediated by cholecystokinin (CCK) A receptors. SUBJECTS AND METHODS Three sequential(More)
Intraduodenal fat inhibits gastric emptying and exerts early satiation in animals and humans, but it is not clear whether the effects are mediated by cholecystokinin (CCK) in humans. Here, we tested whether CCK-A receptors mediate the inhibition of fat on food intake. Two sequential, double-blind, crossover studies were performed in 24 male subjects. First,(More)
The present review of the satiating effect of cholecystokinin in humans has revealed that cholecystokinin is a physiological satiety factor in humans. The results demonstrate the efficacy of the satiating actions of exogenous and endogenous CCK in humans. The therapeutic potential of CCK analogues cannot be estimated until further studies are performed that(More)
Exogenous cholecystokinin (CCK) induces early satiety when infused into humans. Whether alimentary CCK (CCK-A) receptor blockade stimulates food intake in humans is, however, uncertain. The aim of the present investigation was, therefore, to establish the effect of CCK-A receptor blockade on satiety and eating behavior in healthy volunteers. To further(More)
Glucagon-like peptide-1 (GLP-1) and CCK-33 were intravenously infused alone or in combination into normal weight men for 60 min before they were served a lunch of ham sandwiches, chocolate mousse, and orange juice. Infusion of GLP-1 (dose: 0.9 pmol x kg(-1) x min(-1)) or CCK-33 (dose: 0.2 pmol x kg(-1) x min(-1)) each reduced calorie intake of the test(More)
