Abstract:
Faster eating has been identified as a risk factor for obesity and the current study tested
whether eating rate is consistent within an individual and linked to energy intake across multiple
meals. Measures of ad libitum intake, eating rate, and oral processing at the same or similar test meal
were recorded on four non-consecutive days for 146 participants (117 male, 29 female) recruited
across four separate studies. All the meals were video recorded, and oral processing behaviours
were derived through behavioural coding. Eating behaviours showed good to excellent consistency
across the meals (intra-class correlation coefficients > 0.76, p < 0.001) and participants who ate faster
took larger bites (β ≥ 0.39, p < 0.001) and consistently consumed more energy, independent of meal
palatability, sex, body composition and reported appetite (β ≥ 0.17, p ≤ 0.025). Importantly, eating
faster at one meal predicted faster eating and increased energy intake at subsequent meals (β > 0.20,
p < 0.05). Faster eating is relatively consistent within individuals and is predictive of faster eating and
increased energy intake at subsequent similar meals consumed in a laboratory context, independent
of individual differences in body composition.
