    <description descriptionType="Abstract">&lt;p&gt;Background:&lt;/p&gt;

&lt;p&gt;Repeatedly pushing high-calorie food stimuli away based on joystick movements has been found to reduce approach biases towards these stimuli. Some studies also found that such avoidance trainings reduced consumption of high-calorie foods.&lt;/p&gt;

&lt;p&gt;Objective:&lt;/p&gt;

&lt;p&gt;To make such interventions suitable for daily use, this preregistered study tested effects of a smartphone-based approach&amp;ndash;avoidance intervention on chocolate craving and consumption.&lt;/p&gt;

&lt;p&gt;Methods:&lt;/p&gt;

&lt;p&gt;Within a ten-day period, participants (n = 105, 86% female) either performed five sessions during which they continuously avoided (i.e., swiped away/upwards) chocolate stimuli (experimental group, n = 35), performed five sessions during which they approached and avoided chocolate stimuli equally often (placebo control group, n = 35), or did not perform any training sessions (inactive control group, n = 35). Training effects were measured during laboratory sessions before and after the intervention period and further continuously through daily ecological momentary assessment (EMA).&lt;/p&gt;

&lt;p&gt;Results:&lt;/p&gt;

&lt;p&gt;Self-reported chocolate craving and consumption as well as body fat mass significantly decreased from pre- to post-measurement across all groups. EMA reports evidenced no differences in chocolate craving and consumption between intervention days and rest days as a function of group.&lt;/p&gt;

&lt;p&gt;Conclusions:&lt;/p&gt;

&lt;p&gt;A smartphone-based approach&amp;ndash;avoidance training did not affect eating-related and anthropometric measures over and above measurement-based changes in the current study. Future controlled studies need to examine whether other techniques of modifying food approach tendencies show an add-on benefit over conventional, monitoring-based intervention effects.
