    Theoretically driven smartphone-delivered behavioral interventions that target mechanisms underlying eating behavior are lacking. In this study, we administered a 28-day self-paced smartphone-delivered intervention rooted in an operant conditioning theoretical framework that targets craving-related eating using mindful eating practices. At pre-intervention and 1-month post-intervention, we assessed food cravings among adult overweight or obese women ( N  = 104; M age = 46.2 ± 14.1 years; M BMI = 31.5 ± 4.5) using ecological momentary assessment via text message (SMS), self-reported eating behavior (e.g., trait food craving), and in-person weight. Seventy-eight participants (75.0%) completed the intervention within 7 months (‘all completers’), and of these, 64 completed the intervention within 3 months (‘timely completers’). Participants experienced significant reductions in craving-related eating (40.21% reduction; p  < .001) and self-reported overeating behavior (trait food craving, p  < .001; other measures p s < .01). Reductions in trait food craving were significantly correlated with weight loss for timely completers ( r  = .30, p  = .020), this pattern of results was also evident in all completers ( r  = .22, p  = .065). Taken together, results suggest that smartphone-delivered mindful eating training targeting craving-related eating may (1) target behavior that impacts a relative metabolic pathway, and (2) represent a low-burden and highly disseminable method to reduce problematic overeating among overweight individuals.
