Breaking down the statistics even further, Fryer's team found that black consumers were more likely to have eaten fast food on a given day than white consumers (42 percent compared to 38 percent, respectively).
Pick a day at random, and you can bet that almost 40% of Americans will eat fast food during those 24 hours, according to a new report from the Centers for Disease Control and Prevention's National Center for Health Statistics (NCHS).
The report - which drew its findings from information collected from 10,000 adults between 2013 and 2016 as part of the National Health and Nutrition Examination Survey - found that fast food intake was higher among consumers in middle- and higher-income brackets. That's about 85 million people.
Men are more likely to eat fast food at lunch, according to the CDC, but women tend to eat fast food as a snack more often than men.
When it came to gender, men were most likely to buy fast food for lunch, while women would purchase it as a quick and low-priced snack. And among high-income families (those with incomes above 350% of the poverty line), 42% dined on fast food on a typical day.

It was the least enticing to Asian Americans, though 30.6 percent of them ate it on a typical day as well.
That 91% was an increase from 79% of 771 parents in a 2010 survey and 83% of 835 parents in a 2013 survey, according to the Rudd Center report.
Still, the CDC said that fast food's ubiquity and price can make it an attractive option for some people.
"When we see news clips of a shark swimming near a beach, it scares us into not going near that beach", Weinandy said.
"These findings remind us that fast food companies have figured out a way to conveniently fit into our daily routine, despite their [products'] negative health implications", Boehmer said. "However, what we should be scared of is double cheeseburgers, French fries and large amounts of sugary beverages", Weinandy said.
