Abstract A highly structured test meal situation was used to examine the metabolic and behavioral response of restrained and unrestrained eaters to a disguised calorific preload. Both restrained and unrestrained eaters ate initially more quickly after drinking a disguised glucose preload, compared with those who drank a glucose‐free preload. Restrained eaters showed a comparatively greater increase in rate of eating, which tended to persist as a greater overall food consumption. The unrestrained group compensated for their initially greater consumption by eating less later in the meal. The excess eating occurred in conjunction with the release of excess insulin compared with circulatory glucose in response to the preload. In the unrestrained subjects, this declines together with the compensatory decrease in food consumption. For restrained eaters, the elevation of insulin/glucose ratio persisted and was comparatively greater, in conjunction with a persistent and relatively greater enhancement of food intake. Subjective reports and ratings indicated that the subjects were aware of neither the presence nor the behavioral and metabolic effects of the preload. The results suggest a possible metabolic component to the phenomenon of counterregulation.
