Restrained eating, eating disorders and obesity have been associated with cardiac autonomic dysregulation. The current study investigated cardiac autonomic regulation in current dieters. Female students (N = 50) indicated if they were currently trying to control their weight and completed the Perceived Self-Regulatory Success in Dieting Scale (PSRS). Heart beat intervals were recorded during two 10 min relaxation periods from which parameters of vagal-cardiac control (high frequency power in normalized units, HF n.u.) and sympathovagal balance (ratio of low and high frequency power, LF/HF) were calculated. In current dieters, self-reported dieting success was positively associated with HF and negatively associated with LF/HF. These associations were independent of current body-mass and food deprivation (i.e. hours since the last meal). We conclude that vagal-cardiac control reflects self-regulatory strength, rather than nutritional status, in current dieters.
• We investigated cardiac autonomic regulation in relation to dieting in healthy women.
• Dieting success was related to vagal-cardiac control and sympathovagal balance in current dieters.
• Current body-mass and food deprivation did not influence results.
• Vagal-cardiac control may reflect self-regulatory strength in dieters.
