The name of a food product often does or does not contain the association with healthy information, and it may work as a clue for consumers to evaluate a food product’s nutrition value. Notably, the influence of product name on food evaluations is likely to vary on the basis of individual dieting tendency. Differences exist in dieters’ and nondieters’ perception and preference of their food product choice. Dieters are in accordance with their dieting tendency when they choose their food products; while consumers who are not on a diet have no such concern in choosing food products. Considering their concerns on avoiding diet-unfriendly food items, dieters try to classify food products as “forbidden”; compared with nondieters, dieters usually classify greater number of foods as forbidden. So, dieters pay more attention to their own forbidden food products, by such ways they can avoid less healthful food products. Unhealthy name of food product may lead dieters who have paid chronic attention to forbidden food categories to associate unhealthfulness towards the food product. In other words, when choosing food product, consumers are influenced and limited by their cognitive resources towards food products. What more important is that the influences of cognitive resources bearing on dieters are clearer than that on the nondieters, the reason is that dieters’ persistent thoughts are always preoccupied by the concerns about their eating and body shape.
