Autonomic nervous system functioning, measured with heart rate variability (HRV), is associated with emotion regulation and likely contributes to binge eating. This study examined the link between HRV and binge eating severity and analyzed changes in HRV as a marker of emotion regulation in individuals with binge eating. Participants (n鈥?鈥?8) with obesity and loss of control eating reported overeating and loss of control episodes and completed an HRV assessment at rest and during a mental stressor. At rest, lower time-domain HRV was linked to more severe loss of control (SDNN B鈥?鈥?0.18, p鈥?鈥?.03). Frequency-domain HRV was associated with more severe overeating (LFn B鈥?鈥?4.92, p鈥?鈥?.03; HFn B鈥?鈥?14.81, p鈥?鈥?.04). Frequency-domain HRV differed between resting and stressed conditions (p\'s鈥?鈥?.001). Findings contribute to understanding emotion regulation in binge eating and guide future research and novel intervention development.
