Love Matters: The Effect of Mating Motive on Female Food Choice

The prevalence of obesity has been increasing globally in recent decades. Behind the phenomenon, high-fat food consumption has been conceived as an important driver. In the current study, we explored whether mating motive caused an effect on female food choice as well as the psychological mechanism underlying it. In Study 1, we recruited 64 participants from a university and asked them to complete a mating prime, after which they would finish a food choice task in which food with different flavors were shown. In Study 2, we replicated Study 1 with a different mating priming method and examined the mediating role of body shaping desire on the relation between mating motive and female food choice. Results showed that: (1) The salience of mating motive decreased female's high-fat food choice but increased male's high-fat food choice; (2) the effect of mating motive in females was robust and more salient for sweet food rather than salty food; and (3) the body shaping desire partially mediated the effect of mating motive on female food choice.
