Trusting homeostatic cues versus accepting hedonic cues: A randomized controlled trial comparing two distinct mindfulness-based intervention components

Abstract

ObjectiveMindfulness-informed cognitive behavioral interventions for obesity are promising. However, results on the efficacy of such treatments are inconsistent which in part may be due to their substantially different methods of practice. This study is the first direct comparison of two theoretically distinct mindfulness-based weight loss approaches: increasing awareness of homeostatic/innate physiological cues versus hedonic/externally-driven cues for eating. MethodsOverweight adults were randomized to one of three group-based workshops: Mindful Eating (ME; n = 21), Mindful Decision-Making (MD; n = 17), or active standard behavioral control (SC; n = 19). Outcome measures included percent weight change and reduction in caloric intake from baseline to 6 weeks. ResultsDifferences in weight loss and calorie reduction did not differ significantly among groups. However, the difference in weight loss between the MD and ME groups trended towards significance, with medium-large effect sizes. ConclusionsResults provide modest preliminary evidence for the utility of mindful decision-making strategies over mindful eating for short-term weight loss and calorie reduction.
