Researchers have discovered why humans frequently eat the same breakfast every day.
Breakfast
People are more likely to eat the same morning meal on a daily basis compared to lunch or dinner because it has a "utilitarian goal" as humans prefer to eat quickly at the start of the day and something healthy to keep weight under control.
Lunch and dinner both have "hedonic goals" which means people look for pleasure and wouldn't be content with eating the same meals every day.
The pattern was seen in separate studies in both France and the United States and hints at a global trend.
Dr. Romain Cadario, who led the study from Rotterdam School of Management, admits that he was inspired to conduct the research after conversations with his colleagues.
He said: "[It] came about because my colleagues and I talked about always having the same breakfast, but how we didn’t worry about it being boring or tedious.
"However we would not even consider having the same dinner for three or four nights in a row."
