It is stated in the passage that ----.

Hunger is known to increase food purchases, but
Alison Jing Xu at the University of Minnesota and her
team wanted to know if it also increased desire to buy
non-food items. They asked 63 people to come to the
lab with an empty stomach. Half were given a piece of
cake to eat before all the volunteers were asked to
examine a binder clip and decide how many they would
like. Hungry participants asked for 70 percent more free
clips than those who had just eaten. To find out if the
same association held true for real purchases, the team
had a look at the receipts of 81 customers leaving a
department store that sold mostly non-food goods.
Customers who were hungrier spent 64 percent more
than the others. So, what is going on? When we are
hungry, our stomach releases a hormone called ghrelin
which acts on an area of the brain that makes people
not only want to consume calories but also to seek out
reward and motivation in buying other things. Jing Xu
and her team suggest that consumers better feed
themselves before they go shopping
