The effects of selected social and environmental variables on the eating behavior of adults in the natural environment

The current study investigated the effects of social setting, type of restaurant environment, relative weight, and sex on the number of calories consumed by adults. Subjects were observed in 14 different restaurants by trained observers. Results indicated that both males and females consumed more calories in fast-food restaurants and that they ate more when in groups as compared to when they ate alone. Females ate less in larger as compared to smaller groups of people. Relative weight was not associated with the number of calories consumed. Implications of the results are discussed and possible treatment recommendations are outlined.
