This study evaluates the influences of chronicity of, and time lag between, dietary restriction and binge outcome for predicting binge episode onset. Sixty-two women aged 18 to 40 years old completed an online survey at random intervals seven times daily for a 7-day period. Participants self-reported engagement in dietary restriction and/or binging, and temptation to binge. Consecutive instances of reported dietary restriction better predicted subsequent binges than single instances. As the time lag between the first report of dietary restriction and binge onset increased, a clear linear trend emerged, such that the value of restriction for predicting binges increased with the number of consecutive assessments in which they reported dietary restriction. A similar pattern was found when predicting temptation to binge. Present findings suggest that duration of restriction is a crucial determinant of binge onset. These findings have implications for clinical practice by highlighting the time course from dietary restriction to binging.
