A physiological role for pleasure has been suggested from observations that glucose loads reduced pleasantness ratings sweet stimuli in normal weight but not weight-reduced subjects. This hypothesis was reexamined fasting and food-loaded, lean obese Magnitude estimates of sweetness were obtained seven sucrose concentrations. Indices obesity including percent overweight, body fat, mass index calculated. Pleasantness subjects either increased up to a moderate concentration then declined (type I hedonic response) or monotonically with II response). Both types response found Within each group there appeared negative correlation between indices obesity. Caloric type subjects, did affect These findings indicate the presence an monitor biased by caloric intake. The data suggest regulating at different set points
