Key result
Higher HRV links to lower cardiac defence response and eating disorder symptoms in female chocolate cravers.
Why the study?
The role of heart rate variability in cardiac defence response and eating disorder symptomatology among chocolate cravers was not well understood.
Does heart rate variability correlate with the cardiac defence response and eating disorder symptomatology in female chocolate cravers?
Cross-Sectional (n=72)
Does heart rate variability correlate with the cardiac defence response and eating disorder symptomatology in female chocolate cravers?
Low heart rate variability is associated with heightened cardiac defence responses and eating disorder symptomatology in chocolate cravers, suggesting poor autonomic regulation plays a role in uncontrolled eating behavior.

Autonomic assessment may flag eating disorder risk in chocolate cravers; leaves open causal role and precludes practice change.
The study examines the effect of heart rate variability (HRV) on the cardiac defence response (CDR) and eating disorder symptomatology in chocolate cravers. Female chocolate cravers (n = 36) and noncravers (n = 36) underwent a psychophysiological test to assess their HRV during a 5-min rest period, followed by three trials to explore the CDR, elicited by an intense white noise, during the viewing of chocolate, neutral, and unpleasant pictures. After the test, participants completed a questionnaire to measure eating disorder symptomatology. The HRV was inversely related to the magnitude of the CDR and to eating disorder symptomatology in chocolate cravers. In addition, the HRV was inversely related to the magnitude of the CDR when viewing unpleasant pictures but not to neutral or chocolate ones, across all participants. These findings support the idea that poor autonomic regulation, indexed by low HRV, plays a relevant role in food craving and uncontrolled eating behavior.

Rodríguez‐Ruiz et al. (2009) conducted a cross-sectional in Chocolate craving (n=72). Heart rate variability (HRV) was evaluated on Cardiac defence response (CDR) and eating disorder symptomatology. Heart rate variability was inversely related to the magnitude of the cardiac defence response and eating disorder symptomatology in female chocolate cravers.
