Why the study?
Although self-regulation is thought to affect dietary restraint under stress, it had not been evaluated alongside its physiological correlates, such as heart rate variability.
Does acute mental stress alter food intake through changes in heart rate variability, and is this moderated by dietary restraint in female undergraduates?

Individuals with higher dietary restraint show a disconnection from internal physiological cues (HRV) that typically affect food intake under stress.
No takes yet. Share an insight, caveat, or question.
Stress-induced HRV reduction curbs intake only in low-restraint women; extends causal evidence that restraint disrupts physiological regulation of stress-eating.
McGeown et al. (2024) studied this question.
