Salivary response to olfactory food stimuli as a function of dietary restraint and body weight.
The effects of food and non-food odors on salivation rate and the relation between this response, body weight for height and dietary restraint score were investigated in college students. Potential confounding variables, such as dieters' anxiety due to expectations of food consumption, intrusive methods of salivation collection, and the degree of dieting strictness, were controlled. Results indicated that dietary restraint, but not body weight per se, predicted hyper-responsiveness to food cues, supporting the view that self-imposed dietary restriction heightens external salivary responsiveness to food-related stimuli.
