Arch Gen Psychiatry. 1980;37(10):1133-1135. doi:10.1001/archpsyc.1980.01780230051007

• A set of naturalistic observations was conducted to examine Schachter's theory that obese individuals are more responsive to external food cues than persons of normal weight. During six days of observation at a large hospital cafeteria, experimenters manipulated the accessibility of high- and low-calorie desserts. No differences in selection by obese, overweight, and normalweight individuals of meals or desserts were observed. All weight groups were equally responsive to the experimental manipulation of food cues.
