Bodily sensations and bariatric surgery: Links between interoceptive sensibility, intuitive and disordered eating behaviour in obesity and obesity surgery.

Abstract

This study evaluated interoceptive sensibility, intuitive and disordered eating among bariatric candidates, operated individuals and individuals with obesity seeking non-surgical treatment. We recruited 57 individuals with obesity seeking nonsurgical weight-loss (IOB), 84 bariatric candidates (Pre) and 22 individuals post-bariatric surgery (Post) who responded to questionnaires: Multidimensional Assessment of Interoceptive Awareness, Intuitive Eating Scale-2 (IES-2), Dutch Eating Behaviour Questionnaire, Binge Eating Scale, State-Trait Anxiety Inventory, Beck's Depression Inventory. Overall, the Post group manifested higher scores on 'Body-Listening' (F=4.95, p=0.01), 'Emotional Awareness' (F=8.83, p<0.001) and 'Trusting' (F=6.71, p=0.002) interoceptive dimensions, on the IES-2 total score (F=5.48, p=0.007) and 'Reliance on hunger and satiety cues' (F=31.3, p<0.001) when age was controlled. The IOB group presented higher scores on emotional (F=3.23, p=0.047) and binge eating (F=5.99, p=0.004). Among operated individuals, intuitive eating mediated the relationship between interoceptive sensibility dimensions and binge eating: 'Attention regulation' (54%) 'Self-regulation' (75.1%), 'Body listening' (94.09%) and 'Trusting' (84.9%). Our results suggest the therapeutic potential of interoceptive sensibility and intuitive eating in obesity management in/beyond the bariatric context.
