Happy Wife, Happy Life: Food Choices in Romantic Relationships

The authors extend research on dyadic decision making by examining how relationship partners influence consumer eating patterns. Using research from relationship science and evolutionary psychology, the authors find that romantic relationship motives of formation and maintenance influence eating behaviors. Specifically, females are influenced by the eating patterns (i.e., healthiness/unhealthiness) of males when relationship formation motives are active, while males are influenced by the eating patterns of females when relationship maintenance motives are active. Furthermore, perceptions of relational influence differ between relationship formation and maintenance, which underlies these observed effects. This research contributes to the consumer behavior literature by revealing the powerful influence of relationships on food consumption.
