Abstract: Loss of control eating (LOC), defined as feeling unable to stop eating and/or control the amount or type of food eaten during an eating episode, is the core element of binge spectrum disorders. LOC is often reported among individuals without diagnosed eating disorders and is particularly common among individuals with higher body mass indices. LOC is also common during pregnancy, which is an important window to affect weight and promote health behaviors. Evidence-based interventions to address LOC exist outside the perinatal period. For example, cognitive behavioral therapy (CBT) has consistently been shown to effectively reduce LOC among non-perinatal individuals with BMI≥25. However, there are no data on the efficacy of interventions to address LOC among pregnant individuals, let alone pregnant individuals with BMI≥25 who are at high risk for poor long-term health outcomes. Given this, and mounting evidence that supports the high prevalence of prenatal LOC, the links between prenatal LOC and prenatal distress, the unique changes in eating, weight, and shape that accompany pregnancy, and relevance of the perinatal period to the longer-term health of both birthing individuals and their offspring, interventions designed to address prenatal LOC are needed. Thus, we aimed to examine the impact of a CBT-based perinatal lifestyle intervention, designed to address weight and well-being among individuals with pre-pregnancy BMI ≥25, on prenatal LOC using data from a recently completed clinical trial.
