A comparison of chewing rate between overweight and normal BMI individuals

Abstract

Objective: Previous attempts to identify an 'obese eating style' have led to conflicting findings. This observational study compared the chewing features of overweight or obese young adults with those of normal range BMI. We hypothesised that chewing features are individual-specific and differ between participants of a normal BMI and high BMI. Methods: Fourteen overweight to obese participants (BMI. ≥. 25.0) were pairwise matched with 14 normal range BMI participants (18.5. . 0.05), whereas chewing power was significantly higher in high BMI participants (p.. 0.05). Masticatory performance did not differ significantly (p. >. 0.05) between the high (55.9%) and normal (52.4%) BMI groups. Conclusions: Within the limitations of the present study, chewing characteristics appear to be individual-specific with wide variability. Overweight participants chew at a similar rate to control participants, albeit slightly stronger. Our preliminary findings need to be replicated in larger samples.
