Abstract

Background

In today’s food-rich society, the prevalence of dieting is remarkably high among adolescent girls and young females striving to achieve their ideal slim figure. Nonetheless, most individuals fail to maintain long-term dieting plans due to increased hedonic cravings for appetitive, high-calorie foods. Young dieting females are often confronted with two antagonistic motivational conflicts: the hedonic impulse and the pursuit of the slim ideal. Moreover, the trait of disinhibition plays a crucial role in dieting failures and hedonic overeating.

Objective

The present study aims to examine the moderating effects of the disinhibition trait on the antagonistic motivational processes between hedonic impulse and slim ideal pursuit among young dieting females.

Methods

Participants with high and low disinhibition traits performed a food-versus-figure task to determine the conflicting motivational processes.

Results

The findings showed that the balance between the hedonic “hot” and the slim ideal “cold” pathways was moderated by disinhibition. Specifically, only high-disinhibition dieters exhibited stronger food conflict than slim conflict, suggesting a pronounced preference for appetitive foods over the slim body ideal.

Conclusion

These findings enhance our understanding on the role of automatic hedonic impulse and the disinhibition trait in dieting failure, potentially clarifying why some individuals are more vulnerable to hedonic overeating and food addiction.
