Self-regulatory theory and weight-loss maintenance.

Area of Science:

• Psychology
• Behavioral Science
• Nutrition Science

Background:

• Dietary lapses are common challenges for individuals maintaining weight loss.
• Understanding psychological factors influencing post-lapse eating behavior is crucial for effective weight management.

Purpose of the Study:

• To investigate the relationship between promotion and prevention focus and caloric intake following a controlled dietary lapse.
• To examine the mediating role of anxious and depressive affect in this relationship.

Main Methods:

• Sixty-five adult females with a minimum 10% weight loss maintained for at least one month participated.
• Following a simulated dietary lapse in a laboratory setting, participants engaged in an unrestricted "bogus" taste test.
• Promotion and prevention focus, alongside affect, were assessed.

Main Results:

• Prevention focus, but not promotion focus, was significantly associated with higher caloric consumption after the dietary lapse.
• Affect (depressive and anxious) did not mediate the relationship between focus and caloric intake.
• The findings suggest prevention focus might be detrimental to dietary maintenance.

Conclusions:

• Prevention focus may pose a risk for weight loss maintenance following dietary lapses.
• Clinical interventions may need to address prevention-oriented mindsets to improve long-term dietary adherence.
• Future research should explore strategies to mitigate the negative impact of prevention focus.
