Compared with non‐FA subjects, those with FA craved foods more frequently, and had higher scores for emotional and external eating behaviors (all <italic>P</italic>‐values <0.01; all Cohen's <italic>d</italic> >0.8). Surgery‐induced weight loss resulted in remission of FA in 93% of FA subjects; no new cases of FA developed after surgery. Surgery‐induced weight loss decreased food cravings, and emotional and external eating behaviors in both groups (all <italic>P</italic>‐values < 0.001; all Cohen's <italic>d</italic> ≥ 0.8). Restrictive eating behavior did not change in non‐FA subjects but increased in FA subjects (<italic>P</italic> < 0.01; Cohen's d>1.1).</p> </sec> <sec id="oby20797-sec-0004" sec-type="section"> <title>Conclusion</title> <p>Bariatric surgery‐induced weight loss induces remission of FA and improves several eating behaviors that are associated with FA.</p> </sec> </abstract>
