Key result
Weight reduction of 17.8% using a very-low-calorie diet improved heart rate variability in obese patients, increasing the mean normal R-R interval and high-frequency component.

Does very-low-calorie diet-induced weight loss improve heart rate variability in moderately obese Japanese patients?
Significant weight loss achieved through a very-low-calorie diet improves autonomic nervous system function, particularly nocturnal heart rate variability, in moderately obese patients.
Akehi et al. (2001) conducted an observational in Obesity (n=16). Very-low-calorie conventional Japanese diet (VLCD-CJ) and behavior therapy vs. Baseline (pre-weight reduction) was evaluated on Heart rate variability (HRV) based on 24-hr ambulatory ECG recordings. Weight reduction of 17.8% using a very-low-calorie diet improved heart rate variability in obese patients, increasing the mean normal R-R interval and high-frequency component.
