The effect of a mindfulness-based body scan exercise on food intake during TV watching.

A brief body scan meditation did not reduce snack consumption in a distracted setting, despite increasing state mindfulness. In a study with 137 participants, those who listened to a 10-minute body scan ate about the same amount of crisps (34.79g) while watching TV as those who listened to a control visualization (33.16g). The body scan raised state mindfulness but did not affect attention to bodily sensations, eating automaticity, or food intake. State mindfulness was linked to greater attention to bodily sensations while eating. Lower eating automaticity and relying on decreased food appeal and physical satisfaction to stop eating were associated with eating less. The authors argue that mindfulness may not reduce food intake when people are distracted, and future work should clarify the conditions under which it might.

Abstract

In some studies mindfulness is associated with reduced food consumption, but the underlying mechanisms are less well researched. One potential mechanism is that mindfulness increases attention toward feelings of fullness. Additionally, experimental research on mindfulness and food intake has primarily been conducted in constrained laboratory settings, where it may be easier for participants to notice their internal bodily signals, as opposed to the real-world where individuals are often engaged in other activities while eating. The effect of mindfulness on food intake while participants are distracted remains unexplored. This study therefore aimed to examine whether a mindfulness-based body scan exercise reduced food consumption within a distracted environment by increasing attention toward feelings of fullness. Participants (n = 137) listened to a 10-min body scan meditation, or a 10-min visualisation (control) meditation. They were then given a bowl of crisps to consume while watching a 10-min TV show segment. Participants also completed measures assessing proposed mediators, including state mindfulness, attention to bodily sensations and eating automaticity. The body scan manipulation increased state mindfulness but had no direct effect on the other mediators or on food intake (intervention M = 34.79g, SD = 24.06; control M = 33.16g, SD = 23.88). State mindfulness was positively correlated with attention to bodily sensations while eating. Lower eating automaticity and greater reliance on decreased food appeal and physical satisfaction to stop eating were found to be associated with lower food intake. Contrary to previous studies, we found no evidence that a mindfulness body scan reduces food consumption when participants are distracted. Future research should examine the specific conditions under and mechanisms by which mindfulness may influence food consumption.
