Successful and unsuccessful restrained eating. Does dispositional self-control matter?

Area of Science:

• Psychology
• Behavioral Science
• Health Psychology

Background:

• Dietary restraint is a common weight management strategy.
• Individual differences in self-control may influence the effectiveness of dietary restraint.
• Understanding these factors is crucial for developing targeted weight management interventions.

Purpose of the Study:

• To investigate the role of dispositional self-control in the weight control success of restrained eaters.
• To examine the interaction between dietary restraint and self-control on body mass index (BMI).

Main Methods:

• A random population sample (N=1078) was surveyed.
• Regression analysis was used to assess the relationship between dispositional self-control, dietary restraint, and BMI.
• Subgroup analyses were conducted for restrained eaters, and separately for males and females.

Main Results:

• Dispositional self-control was negatively associated with BMI, while dietary restraint was positively associated with BMI.
• A significant interaction indicated that self-control was more strongly associated with lower BMI in restrained eaters.
• Among female restrained eaters, high self-control correlated with normal BMI, while low self-control correlated with overweight BMI. Similar, though less pronounced, patterns were observed in males.

Conclusions:

• High dispositional self-control is a key factor facilitating successful weight control in individuals who practice dietary restraint.
• These findings highlight the importance of self-control as a moderator in the relationship between dieting and weight outcomes.
• Interventions aimed at enhancing self-control may improve the efficacy of weight management programs for restrained eaters.
