Effects on Metabolism Produced by the Rate of Ingestion of the Diet

"Meal Eating" Versus "Nibbling"

CLARENCE COHN M.D.1 and DOROTHY JOSEPH 1

1 From the Department of Biochemistry, Medical Research Institute, Michael Reese Hospital, Chicago, Illinois

Animals induced to meal eat (consume full spaced meals) differ from those allowed to nibble (eat frequent small feedings) with respect to over-all body metabolism. Meal eating, when compared to nibbling, is associated with the following: (1) increased body fat, (2) decreased body protein, (3) changed tissue enzymatic activities. (4) altered thyroid activity, (5) an increased incidence of diabetes mellitus in partially depancreatized rats and (6) an enhanced development of and an inhibition in the regression of experimental atherosclerotic lesions. These results are interpreted to be the result of a role the rate of ingestion of the diet plays in the regulation of intermediary metabolism. It is believed that the rate of influx of calories alters traffic over specific enzymatic pathways, when multiple pathways are available, hence it affects the metabolism of fat, carbohydrate and protein.
