ZEIST, Netherlands--Protein is more satiating than carbohydrate, according
to a study published in the American Journal of Clinical Nutrition (83,
2:211-20, 2006).
In the single blind, crossover study, researchers administered an isocaloric
high-protein breakfast (58.1 percent of energy from protein and 14.1 percent
of energy from carbohydrate) or high-carbohydrate breakfast (19.3 percent of
energy from protein and 47.3 percent of energy from carbohydrate) to15
healthy men. Blood samples and subjective measures of satiety were assessed
frequently for three hours after consumption. The high-protein breakfast
decreased secretion of postprandial ghrelin (a hormone that stimulates
hunger) more than did the high-carbohydrate breakfast. Appetite ratings were
not significantly different between the two groups, and the high-protein
breakfast did not significantly affect ad libitum energy intake.
The researchers concluded the high-protein breakfast decreased postprandial
ghrelin concentrations more strongly over time than did the high-carb
breakfast, and noted high associations between ghrelin and glucose-dependent
insulinotropic polypeptide and glucagon suggest stimulation of these
peptides may mediate the postprandial ghrelin response. In addition, the
high-protein breakfast also reduced gastric emptying, probably through
increased secretion of cholecystokinin and glucagon-like peptide 1, the
researchers said.
