Understanding of how WM performance relates to eating behavior in real\u2010time is currently limited.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We studied 32 youth (ages 10\u201317\u2009years) with LOC eating and overweight\/obesity (LOC\u2010OW; <jats:italic>n<\/jats:italic>\u2009=\u20099), overweight\/obesity only (OW; <jats:italic>n<\/jats:italic>\u2009=\u200916), and non\u2010overweight status (NW; <jats:italic>n<\/jats:italic>\u2009=\u20097). Youth completed spatial and numerical WM tasks requiring varying degrees of cognitive effort and reported on their eating behavior daily for 14\u2009days via smartphone\u2010based ecological momentary assessment. Linear mixed effects models estimated group\u2010level differences in WM performance, as well as associations between contemporaneously completed measures of WM and dysregulated eating.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>LOC\u2010OW were less accurate on numerical WM tasks compared to OW and NW (<jats:italic>p<\/jats:italic>s\u2009&lt;\u2009.01); groups did not differ on spatial task accuracy (<jats:italic>p<\/jats:italic>\u2009=\u2009.41). Adjusting for between\u2010subject effects (reflecting differences between individuals in their mean WM performance and its association with eating behavior), within\u2010subject effects (reflecting variations in moment\u2010to\u2010moment associations) revealed that more accurate responding on the less demanding numerical WM task, compared to one's own average, was associated with greater overeating severity across the full sample (<jats:italic>p<\/jats:italic>\u2009=\u2009.013). There were no associations between WM performance and LOC eating severity (<jats:italic>p<\/jats:italic>s\u2009&gt;\u2009.05).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Youth with LOC eating and overweight\/obesity demonstrated difficulties mentally retaining and manipulating numerical information in daily life, replicating prior laboratory\u2010based research.
