The Monthly Consumer Survey from BIGinsight indicated McDonald's patrons were the unhappiest -- 24 percent who ate at the Gold Arches said they were unhappy or totally unhappy with their health, followed by 22.7 percent who ate at Taco Bell, 22.1 percent who ate at Wendy's and 21.5 percent at Burger King. Customers of these restaurants tend to have a more negative opinion of their own physical condition versus the general population.
Almost 54 percent of the general public said they were happy with their health, while 21.4 percent of Americans said they were unhappy with their health, the survey said.
On the other hand, Chick-fil-A diners report being the happiest with their health -- 58.9 percent said their were happy or totally happy with their health, followed by Subway and Arby's customers at 57.1 percent and 56.6 percent, respectively.
"Given that Chick-fil-A, Subway and Arby's all offer menu items with a calorific punch, it's apparent that Americans' overall personal health perceptions aren't specific to their fast food chain of choice," Pam Goodfellow, consumer insights director at BIGinsight, said in a statement. "We've found that it boils down to their health habits, including exercising regularly and watching fat and calorie intake."
The survey involved 8,716 people and was conducted in February. The margin of error is 1.1 percentage point.
