    <subfield code="a">&lt;p&gt;Objective. Dietary restraint is a common, yet controversial practice to tackle overweight. Yet,&lt;br&gt;
despite good intentions to reduce food intake, most restraint-based diets fail to produce long term&lt;br&gt;
weight loss. A better understanding of the naturalistic course of daily dieting intentions and their&lt;br&gt;
effectiveness in guiding subsequent eating behavior are therefore needed.&lt;br&gt;
Method. In two studies, participants (n=49 and n=59) reported both their state intention to restrict&lt;br&gt;
eating on the next day, as well as their actual restriction on that day via smartphone-based&lt;br&gt;
evening reports of 12 and 10 days, respectively. Intention-behavior gap scores were calculated as&lt;br&gt;
differences between intention at t1 (e.g. evening intention Monday for restriction Tuesday) and&lt;br&gt;
restriction at t2 (evening report of actual restraint on Tuesday). Restriction-related trait&lt;br&gt;
questionnaires served as predictors of general intention or restriction level, whereas several traitlevel&lt;br&gt;
disinhibiting eating style questionnaires served as predictors for intention-behavior gaps&lt;br&gt;
(difference scores).&lt;br&gt;
Results. Daily intentions to restrict were rated higher than the daily actual restrictive behavior.&lt;br&gt;
Participants with higher scores on restriction-related questionnaires (restrained eating, dieting,&lt;br&gt;
reversed intuitive eating) showed higher levels of daily state intention and restriction. Larger state&lt;br&gt;
intention-behavior gaps, by contrast, were seen in participants scoring high on trait-level&lt;br&gt;
disinhibiting eating styles (emotional eating, stress eating and food craving).&lt;br&gt;
Discussion. The results point to potential risk factors of diet failure in everyday life: emotional,&lt;br&gt;
stress eating, and food craving are disinhibiting traits that seem to increase intention-behavior&lt;br&gt;
gaps. These findings can inform individualized weight-loss interventions: individuals with&lt;br&gt;
disinhibiting traits might need additional guidance to avoid potentially frustrating diet failures.&lt;/p&gt;</subfield>
