Eighty-five percent of U.S. consumers decide what to eat for dinner the day of the meal — more evidence that convenience is king, according to a new study.

Compared to 2015, convenient meal solutions have become more popular across almost all categories and generations, according to The Why? Behind the Dine, a new report from Jacksonville, Florida-based Acosta and Chicago-based Technomic.

"Whether it's enjoying a family dinner out or picking up carry-out food, diners are seeking convenient, healthy options for themselves and their families," says Colin Stewart, senior vice president at Acosta. "We are seeing more diners take advantage of the seemingly endless array of meal solutions, be it a quick trip through the drive-thru, grocery prepared foods, lunch from a food truck, or preparing dinner using a meal/ingredient kit.”

Among the study’s other finds:

  • Delivery food continues to be a popular meal solution for diners. In the three months leading up to the survey, 51 percent of all U.S. diners and 77 percent of millennial diners reported ordering delivery food.
  • Pizza isn't the only food diners want delivered. Diners surveyed expressed interest in everything from hamburgers (28 percent), chicken wings (27 percent) and Mexican fare (21 percent), to barbecue (14 percent) and desserts (11 percent).
  • In 2015, only eight percent of U.S. diners indicated they had ordered a meal/ingredient kit online. That figure increased by 10 percentage points to 18 percent of total U.S. diners by 2017, with more diners with kids and millennial diners engaging with this option.
