A Korean man on average consumed 2,587.1 kcal on Saturdays, which was higher than the weekly average of 2,418.1 kcal. A Korean woman, on the other hand, consumed 1,792.2 kcal on Saturdays, higher than the weekly average of 1,693.6 kcal.

The study showed that 8.4 percent of surveyed men and 6.4 percent of women ate fried chicken on Saturdays, while 18.8 percent of the men and 14.6 percent of the women consumed carbonated drinks on Saturdays.

Notably, both Korean men and women’s consumption of instant noodles on weekends was 1.3 times higher than on weekdays, while their consumption of fried chicken on weekends was 1.5 times higher than their consumption on weekdays.
