Righty—Hungry, Lefty—Full?

Since snacking is a favorite past-time for many, we often find ourselves sitting in front of the TV, hand mindlessly passing from chip bag to mouth. This comforting cycle can sometimes last the duration of an hour-long show and before we know it, our hand is brushing the bottom of the bag desperately searching for any last morsels.

Since we become classically conditioned to snack over time, this question may seem a bit odd: which hand are you using as the primary transporter of your snacks?

An interesting study from the University of Southern California has been receiving some media face time recently due to its remarkable results. According to this study, people who used their non-dominant hand during nosh sessions consumed 30% less calories than those who employed their usual method.

So, what makes this seemingly arbitrary approach so effective? When we throw a kink in an automatic process – like snacking – our brain gets knocked off course and causes us to become aware of our behavior. This can prompt us to feel fuller sooner, resulting in fewer chips consumed.

The actual details of the 3-part study are pretty clever, too; participants sat in a dark movie theater, watched trailers and snacked on popcorn. The purpose of the dark theater was to create an automatic atmosphere, since many of us associate movies with mindless munching.

In part three of the study some participants were directed to snack with their non-dominant hand while in the movie theater. For those who had previously reported frequent movie time popcorn pig outs, the total amount consumed was 30% less than that of part one of the study.

So the next time you eagerly tear open a bag of cheese puffs, resist the urge to dive in with your dominant hand; you might find yourself reaching for the chip clip much sooner.
