Abstract
Observational research has indicated that modeling of eating style might occur when eating in the presence of an eating companion. This experiment investigated the effect of bite frequency of a same-sex eating companion on bite frequency, meal size and meal duration. A total of 30 normal weight young adults (m/f¿=¿8/22, age: 21.2¿±¿1.9¿years, BMI: 21.2¿±¿1.6¿kg/m2) had three ad libitum meals together with a same-sex confederate (i.e. instructed eating companion). Confederates were instructed to eat at a slow (3¿bites/min), medium (5¿bites/min) or fast (7¿bites/min) bite frequency in randomized order. Eating style was assessed through video registration and weighing left-overs. It was found that the participants' bite frequency was similar during all three conditions, i.e. slow: 3.9¿±¿1.3, medium: 4.0¿±¿1.1, fast: 4.0¿±¿1.3¿bites/min (p¿=¿0.75), as was average bite size (11¿±¿2.6¿g). Time eaten of the participants was shorter in the medium (14.9¿±¿3.6¿min) and fast condition (14.4¿±¿3.7¿min) compared to the slow condition (16.8¿±¿4.8¿min) (post hoc in both cases p¿
