The association between previous success with weight loss through dietary change and success in a lifestyle modification program
Prior work has yielded mixed results regarding the association between previous weight loss and success in a current weight loss attempt. The present study evaluated differences in baseline psychosocial processes, changes in these over time, and weight loss during a yearlong behavioral weight loss program between individuals who have and have not previously been successful losing weight through self-regulating dietary intake. Individuals with prior success had greater weight losses over time than those without. Differences in baseline and change over time in some facets of motivation and self-efficacy were observed, but only differences in attendance accounted for differential weight loss. Prior success with dietary self-regulation may predict better adherence to and success in behavioral weight control programs. Evaluating the type of weight control efforts that have previously helped induce weight losses may help to better match individuals to treatments likely to yield success.
