A: purchasing impulse items
According to a recent study from IHL, the average American woman could lose up to 4.1 pounds in a year by not purchasing impulse items, such as chocolate candies, chips and soda, once they are in the checkout line. Men could lose an average of 3.1 pounds doing the same thing. While women have an overall higher average, men under 25 are the heaviest consumers of caloric impulse items, consuming enough each year for an additional eight pounds.
