Time is a limited resource. Deciding on how to utilize each minute in your 24-hour day is crucial.  However, the choice between using a portion of the day for food shopping, cooking, and cleaning up versus grabbing a fast food meal can have implications for our health and diet quality as well as other aspects of well-being. While fast-food purchases may save time, they have been linked to Americans’ poor diet quality and expanding waistlines.

Time-use patterns may provide clues as to what motivates fast-food purchases and in this way may help inform policies and other initiatives aimed at improving Americans’ diet quality.  Recently, we used time-use diaries from a nationally representative survey to examine how the time-use decisions of those who purchase fast food on a given day differ from the average of the U.S. population.

For this study, we defined a fast-food purchaser as a person who bought food or drink at a restaurant with counter service; that is, the customer paid before consuming the food or beverage purchased. We found that over 2003-2011, those who purchased fast food on an average day spent 57.2 minutes eating and drinking, compared with 67.5 minutes for all consumers.

Moreover, fast-food purchasers were more likely than others to report no time spent on eating or drinking as a main activity. Instead, some engaged in “secondary eating”—i.e., grabbing something to eat during a main activity such as watching television or getting dressed for work. And fast-food purchasers were more likely than U.S. consumers on average to engage in secondary eating while at work or while driving a vehicle.

We also found that fast-food purchasers work more and sleep less. Those who purchased fast food were more likely to spend less time sleeping—on average 23 minutes a day less than the total population average. This is a considerable difference in the world of time-use averages, and other research has found that less sleep is associated with poorer food choices.

Further discussion on the time-use patterns of  fast-food purchasers, as well as shifts in fast food purchasing behavior following the 2007-09 recession, can be found  in our recent ERS report, The Role of Time in Fast-Food Purchasing Behavior in the United States.
