Les biais perceptuels influençant la consommation alimentaire et l'évolution de l'obésité

In this article we present a synthesis of research in consumer psychology on some external factors that could cause perceptual biases that influence food decisions. We focus specifically on two characteristics of the food easily modified by the marketing: the size and name portions as well as the labels and the positioning of food products. We first present the effects of these biases on overeating and then discuss different strategies to reduce their impact.
