A collaboration between Liverpool and Bristol University found that people who swap and change their brands are more likely to over-consume than those who stick to the same brand. The researchers identified over 70 different brands of peperoni pizza, each with dramatically differing calorie content. By switching brands, consumers were not accommodating for the calorie differences when they were choosing foods to consume later in the day. The brand-switchers would also be under the impression that a slice of pizza would not be filling and thus carry on eating more food. Switching brands like this makes it difficult for consumers to learn about the nutrition of food and manage their consumption.
