Do distant foods decrease intake? The effect of food accessibility on consumption
Methods: In Study 1 (N = 77) and Study 2 (N = 54) distance to a bowl of snacks was randomly varied at 20, 70 or 140 cm in an experimental between-subjects design. Main outcome measures were the number of people who ate any snacks (probability of snack intake), the amount of snacks consumed and risk of compensatory behaviour as measured by food craving. In Study 2, self-report ratings of salience and effort were examined to explore potential underlying mechanisms.
Results: Study 1 showed lower probability and amount of intake in either of more distant conditions (70 and 140 cm) compared to the proximal condition (20 cm), with no unintended effects in terms of increased craving. Study 2 replicated the results of Study 1 and showed that distance affected perceived effort but not salience.
Conclusions: Making snacks less accessible by putting them further away is a potentially effective strategy to decrease snack intake, without risk of compensatory behaviour.
